accurate<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Perhaps the most unique and defining feature of the iO Series 9 is its ability to track the position of the toothbrush in your mouth using sensors built into the handle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The iO9 is Bluetooth-enabled, making it a smart toothbrush. This allows data to be transferred from the brush handle to an Oral-B app on your smartphone, which provides visual insights into how you are brushing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a general rule, we don\u2019t recommend smart brushes. You can brush your teeth just as well without one, they use more resources and they are usually more expensive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nonetheless, the intention is that the data is presented by the app in such a way that it educates you and encourages you to pay more attention to what you are doing.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-28.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>Oral-B smartphone app tracks the real-time position of the toothbrush and gives a coverage score.<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">The 16 zone tracking is more granular than other iO models<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike the vast majority of iO Series brushes that track 6 zones, the iO Series 9 (and the iO10) have 16 zone tracking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When tracking 16 zones, you are essentially tracking specific tooth surfaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those zones are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Upper rear right (inner, outer &amp; biting)&nbsp;<\/li>\n\n\n\n<li>Upper front (inner &amp; outer)<\/li>\n\n\n\n<li>Upper rear left (inner, outer &amp; biting)<\/li>\n\n\n\n<li>Lower rear right (inner, outer &amp; biting)<\/li>\n\n\n\n<li>Lower front (inner &amp; outer)<\/li>\n\n\n\n<li>Lower rear right (inner, outer &amp; biting)<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/wp-content\/uploads\/2022\/07\/Oral_B_iO_16_Zone_Tracking.jpg\" alt=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The logic is that with this more granular data, you can make more focused improvements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, where the iO Series 6 might highlight that you don\u2019t brush your lower back teeth well enough (1 of 6 tracked zones), the iO9 is more specific and shows that you don\u2019t brush the <em>inner<\/em> surface of the back right teeth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The whole system is very clever and with serious commitment, some will gain a real benefit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The tracking is sometimes inaccurate, particularly if you are left-handed<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No brush with real-time tracking \u2014 irrespective of brand \u2014 is perfect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the iO9, there is a real inconsistency in how well the sensor monitors the brush\u2019s position. I\u2019ve yet to establish any notable pattern to the cause. Left handed users (myself included) seem to fare worse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some sessions are better than others. It regularly thinks you are brushing a different zone to the one you are in, or not register it at all. There can also be a noticeable lag\/delay in the visuals.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Marginal improvements have been made, but accuracy should be better. I know many will be frustrated by this.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The app doesn\u2019t force you to brush tooth surfaces in a specific order. I wonder whether it would improve the tracking if it did. It would also be useful for encouraging better techniques and habits.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-16.jpg\" alt=\"\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">The app has some useful customisation features<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Using the Oral-B app you can change the order of the cleaning modes or disable them. You can set specific oral care journeys, change the brushing time and alter the pacing of the timer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can see the remaining battery life and how long you have been using a particular brush head.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You don\u2019t have to use the app every time that you brush your teeth \u2014 the data is retained by the handle and shared with the app next time you use it.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When using the app while you brush, you get a very different screen setup. Not only do you see where you are brushing, but you also see which cleaning mode is selected and how long you have been brushing for. It will show you if you are applying too little or too much pressure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All in all these are useful features, if not essential.&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_App_iO-4.jpg\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_App_iO-4.jpg\" alt=\"\" style=\"object-fit:cover;width:150px;height:300px\"><\/a><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\">You can achieve similar results for less money and without the need for all this tech<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You don\u2019t need a smart toothbrush to achieve clean teeth and make positive improvements to your oral care routine. You can do all you need with a manual brush, if not a cheaper electric toothbrush.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The tech the iO9 offers can certainly help detect areas for improvement, but there is a good chance you already know what these are.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It does make analysing your brushing more fun and engaging, but it comes at a cost.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you're committed to the app enough to gain the insights, it still relies on you making the changes to your technique.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You have the best opportunity to make required changes if you use the app whilst you brush as you will be shown on the screen what\u2019s not going well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But once you\u2019ve perfected everything, then what? Will you continue to use the app once you\u2019ve achieved a nigh-on perfect brushing score every time?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even as someone who tests such products, I don\u2019t regularly use the apps outside my testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To help perfect your brushing technique you could occasionally use plaque disclosing tablets, which are far cheaper.&nbsp;<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">The colour screen looks impressive but impacts battery life<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Series 9 is one of four iO models that have a colour display.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I can\u2019t deny that it looks impressive and adds a certain appeal to the brush. Particularly since the screen hardware has been improved compared to earlier models to offer a sharper and brighter setup. But it does less than you might expect. And it seems to impact the battery life negatively too.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It isn't a touchscreen. The power and mode button are used to control navigation of the modes and settings the display offers. Some might feel it is a little clunky, but it works and is a more robust solution than touch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The biggest benefit, in my opinion, is that it displays an icon and a text label for the cleaning modes. It\u2019s a big step up from the icon only or no icons at all of some other brush handles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Settings like the light ring colour can be controlled via the handle, but many other settings like brushing time are reserved for the app.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During a brushing session, a timer is shown on screen. Albeit the position of such makes it practically useless unless you pause your session to see the time. I still rely on the built-in pacer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An emoji reaction is shown post brushing for some quick visual feedback. Thanks to a 2026 hardware update, it now displays information such as how long I brushed with the ideal pressure and too low pressure. The battery feedback is no longer just a visual icon of the battery, there is an accompanying text based percentage shown. And the remaining days' usage from the brush head is also shown.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral-B_iO_Lifestyle_Shot-22.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>A timer is shown on screen during a standard cycle to show elapsed time.<\/em><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You don\u2019t get any real-time brushing feedback via the screen. It won\u2019t show you if you have missed a zone, for example. Given that tracking and monitoring brushing habits is such a big feature, it seems like an opportunity missed. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Oclean shows Oral-B what needs to be done on their models, like the X Pro Elite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With motion detection, the screen is often activated. A vibration through a bathroom countertop will usually result in the screen waking from its sleep mode. This does impact battery life a bit.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Inconsistent battery life: it doesn\u2019t always reach 2 weeks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With the majority of electric brushes offering a month or more of battery life, the iO9 ranks well below average. Oral-B claims a battery life of 14 days, but I\u2019ve often found it to be worse \u2013 approximately 12 days use is most common from my testing.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite having used the iO9 since its launch a few years ago, I can\u2019t categorically say what\u2019s causing it. My suspicion is the colour display. I will often see it activated as a result of vibration or movement nearby. To my knowledge, other iO brushes have the same lithium-ion battery sealed inside, yet achieve up to 17 days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This isn\u2019t a major issue for the vast majority of users. I wouldn\u2019t say it\u2019s a reason to avoid it, particularly as the Series 9 has a magnetic fast charger capable of topping the battery up in just 3 hours. If you are a frequent traveller it is something to bear in mind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The magnetic charger is circular in shape and wider and deeper than a standard issue Oral-B stand. It doesn\u2019t have the prong on top for the brush to sit on. Instead, a&nbsp; slight convex zone in the centre aligns with the concave base of the iO9\u2019s handle.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-151.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>The magnetic charger is able to recharge the battery fully in just 3 hours.<\/em><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A 2 pin power adapter is hardwired into it. The cord is about 1.2 metres in length. The stand supports 100-240 volts, unlike the 220-240 volts of the standard charger. This is more convenient if you are a regular international traveller.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Feedback on the charge is available via the smartphone app and the screen of the brush. When the power is really low the light ring at the top of the brush handle will flash red. It pulses white when on charge.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/uk\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-121.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>An example of the box contents of the iO Series 9.<\/em><\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">It\u2019s got the features your dentist recommends<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The key features that dentists recommend for an electric toothbrush are a timer, pacer and pressure sensor. The iO9 does have all of these.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pressure sensors don\u2019t come smarter than this<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The visual pressure sensor on the iO9 is one of the best out there. This is useful if you brush too hard or scrub your teeth.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The light ring illuminates in different colours to alert you when you are brushing with too much or too little force:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>White&nbsp; \u2013 low pressure \u2013 not enough force is being applied.&nbsp;<\/li>\n\n\n\n<li>Green \u2013 the right amount of pressure is being used.<\/li>\n\n\n\n<li>Red \u2013 high - excessive pressure is being applied and the force should be reduced.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If using the app it will alert you on screen too.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral-B_iO_Lifestyle_Shot-3.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>The light ring is lit red when too much pressure is applied during brushing.<\/em><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Frustratingly, the alerts are visual only. Blind or partially sighted users will struggle. It would be even better if the handle used a vibration alert, particularly when too much pressure is being applied.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Brush your teeth evenly and for longer<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">2 minutes is the optimum time to rush. Unsurprisingly the iO encourages you to achieve this. As you brush, the motor pauses at 30 second intervals to prompt you to move to the next part of your mouth.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you want to brush for longer you can \u2013 unlike some other brushes, the iO9 doesn\u2019t power off automatically after 2 minutes.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The pacing is deactivated when you use the app and real-time tracking<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When you brush in real-time with the app, the pacing is disabled. The logic is that you are paying attention to the timer and visuals on screen, therefore you don\u2019t need the prompts.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can see when you have brushed each surface and when you should move to the next one.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-175.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>Black onyx brush handle comes with matching brush heads.<\/em><\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">The motion of the larger brush head is gentler and achieves great cleaning results&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It sounds somewhat cliche, but the iO9 does deliver that dentist clean feeling after every use.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Oral-B\u2019s oscillating-rotating and micro vibrating cleaning action is backed by clinical data. The iO9 specifically has achieved the American Dental Association's Seal of Acceptance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The brush heads have gotten bigger and are iO-specific<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With the introduction of the iO Series came a similar, but different range of brush heads.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The long established range of brush heads compatible with the vast majority of Oral-B brushes do not fit iO handles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You now need an <a href=\"https:\/\/www.electricteeth.com\/au\/best-oral-b-brush-head\/\">iO-specific head<\/a>, of which there are 4 styles, when using the iO9.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/wp-content\/uploads\/2022\/08\/Oral_B_iO_Brush_Heads-15.jpg\" alt=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re used to an Oral-B brush head, you may well notice how they have gotten a little bigger. They are approximately 10% deeper. It\u2019s not a big difference, but it is noticeable. If you have a very cramped mouth you may prefer to avoid the iO range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The price has also gone up. On average, iO brush heads are twice as expensive as non-iO Oral-B heads. Expect to now pay $9 per replacement head.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Just like any other toothbrush, you need to replace the bristles every 3 months. The app and brush can track the head and alert you (in the app and via the display) when this is required. It\u2019s useful and not as intrusive as you might think.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A gentler brushing experience<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With the introduction of the iO Series came an entirely new brush motor. This is significant because it has reduced the harshness of the brushing experience.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I\u2019ve always liked the intense clean that the round brush head gives, but some, understandably, have found it to be too much.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is a noticeable difference with the iO Series. It is much softer and ultimately makes for a more enjoyable time using the brush. Importantly it still cleans the teeth just as well.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-11.jpg\" alt=\"\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Quieter, but still quite loud<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The rather loud mechanical noise from older Oral-B models has been replaced with a softer and less irritating sound. It\u2019s an improvement, but it still isn\u2019t at the same more enjoyable pitch of most sonic toothbrushes.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We registered it at up to 72 decibels (dB). That\u2019s only a few dB less than most Oral-B brushes, but it\u2019s noticeable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Newer iO models (Series 3, 4, 5 and 6) have been improved further producing just 64dB.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I can\u2019t help but feel Oral-B has missed an opportunity to really make a significant change. The brush didn\u2019t need to be silent, but it could have been reduced further to compete with the quietest electric toothbrushes.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">The iO9 and its replacement heads are expensive<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You need pretty deep pockets to buy and maintain the iO Series 9. If you can afford and justify it, you are getting a fantastic toothbrush.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The suggested retail price is $749. I wouldn\u2019t blame you if you spat out your coffee whilst reading that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to creative marketing in Australia the actual selling price is typically half this at $375.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is still about 4 times more expensive than our recommendation for the overall <a href=\"https:\/\/www.electricteeth.com\/au\/best-electric-toothbrush\/\" data-type=\"post\" data-id=\"7035\">best electric toothbrush<\/a>!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With iO-specific heads now costing about $9 you can expect the Series 9 to cost $474 over 3 years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As I have made clear, you don\u2019t need to spend this to achieve clean teeth. The <a href=\"https:\/\/www.electricteeth.com\/au\/toothbrush\/pro-2500x\/\" data-type=\"toothbrush\" data-id=\"15359\">Pro 1500X<\/a> costs a third of the price and cleans the teeth just as well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But if you want the best, there is no denying that the tech is impressive, even with some irritations.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral-B_iO_Lifestyle_Shot-16.jpg\" alt=\"\"><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">It\u2019s probably the best looking brush Oral-B has made<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Oral-B has failed to keep up with the competition when it comes to design aesthetics and the iO9 addresses this to a large degree.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It looks much more modern, with a clean and minimal appearance. I particularly like the lack of gloss plastics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Large areas of textured grips found on some handles have been sacrificed here, but the matt finish to the handle creates some resistance to the fingertip.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the palm, the cylindrical handle feels solid and well balanced. It stands upright on a countertop and doesn\u2019t roll when laid on a flat surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is of practical plastic construction, not metal like <a href=\"https:\/\/www.awin1.com\/cread.php?awinmid=32739&amp;awinaffid=242715&amp;ued=https%3A%2F%2Fwww.trysuri.com%2Fproducts%2Fsuri-sustainable-sonic-toothbrush-uv-c-led-case\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.awin1.com\/cread.php?awinmid=32739&amp;awinaffid=242715&amp;ued=https%3A%2F%2Fwww.trysuri.com%2Fproducts%2Fsuri-sustainable-sonic-toothbrush-uv-c-led-case\" rel=\"noreferrer noopener nofollow\">SURI<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, the display helps with the appeal too.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each function button has a slightly concave shape and a different material finish from the rest of the handle, thus it's obvious to the fingertip where it is positioned.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ultimately, the brush, available in 3 colours, white, black and rose quartz is more refined.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Mould can build up inside the head if you\u2019re not careful<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This tooth cleaning device needs to be kept clean too, otherwise you could find a nasty surprise in your brush head.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Failure to properly rinse and clean the brush head after each use has resulted in many people finding mould growing inside the brush head.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s not a new problem with Oral-B brushes and is linked to the holes in the brush head. With the iO range it has become more obvious as a result of the gap around the magnetic attachment point at the top of the handle. It offers an ideal trap and breeding ground for bacteria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The iO9 is water-resistant despite its OLED display and can be happily rinsed under a tap and even used in the shower.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral-B_iO_Lifestyle_Shot-7.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>The iO9 is water resistant and fairly easy to keep clean.<\/em><\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">A brushing mode for every day of the week<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No less than 7 different cleaning modes are available on the iO Series 9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I\u2019ve yet to find anyone who uses them all or any real justification for having so many. The reality is the cleaning results between each are very similar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nonetheless, your choices are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Smart Adapt*<\/li>\n\n\n\n<li>Daily Clean&nbsp;<\/li>\n\n\n\n<li>Sensitive&nbsp;<\/li>\n\n\n\n<li>Whiten&nbsp;<\/li>\n\n\n\n<li>Gum Care<\/li>\n\n\n\n<li>Intense&nbsp;<\/li>\n\n\n\n<li>Tongue Clean&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><em>*From Spring 2026 - Smart Adapt has replaced the Super Sensitive mode that the iO9 previously came with.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">My preference is Daily Clean, but the sensitive mode is nice to have for those times your teeth and gums might be feeling a bit tender. It is also a useful mode for those starting out their journey with an electric toothbrush because it\u2019s not as intense.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike many other models (and that includes other iO models), it is really simple to switch between modes and know which you have selected. You don\u2019t have to remember a specific order or know what each icon means.&nbsp; The colour screen makes it easy to see and select the mode you want.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">The bulky power adapter makes the charging travel case less useful<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The iO9 premium travel case is, in my opinion, the worst available today. Those that come with the Sonicare 9900 Prestige, <a href=\"https:\/\/www.awin1.com\/cread.php?awinmid=32739&amp;awinaffid=242715&amp;ued=https%3A%2F%2Fwww.trysuri.com%2Fproducts%2Fsuri-sustainable-sonic-toothbrush-uv-c-led-case\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">SURI<\/a> and others are far better.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral-B_iO_Lifestyle_Shot-12.jpg\" alt=\"\"><figcaption class=\"wp-element-caption\"><em>A premium charging travel case is included with the Series 9.<\/em><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">It is admittedly one of a select few that have the ability to charge the brush whilst in the case. But, it is hampered by the bulky proprietary power adapter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The competition uses USB connectors and cables. Thus you can likely use the same power adapter for your toothbrush as you can your smartphone (as long as it\u2019s not an iPhone). That is not the case here (excuse the pun).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To be clear, there is no battery in the power2go case. It must be connected to a power outlet to charge the toothbrush.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One redeeming factor is that the 2 pin power adapter does support 100-240v, so you need only a plug adapter when travelling, not a voltage adapter too.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is a very durable travel case too. Thicker and heavier than most, it holds the handle and 1 brush head.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When connected to power, an LED on the outside gives feedback on the charge status.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.electricteeth.com\/au\/wp-content\/uploads\/sites\/3\/2020\/07\/Oral_B_iO_Series_9_Electric_Toothbrush-76.jpg\" alt=\"\"><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">An industry average 2 year warranty<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Where more affordable brushes from lesser known brands typically come with a 1 year warranty, the iO9 is supplied with a 2 year guarantee. This is pretty typical for an Oral-B brush and those from other leading brands like Philips Sonicare.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s not impossible, but not all that common for a brush to fail during this time. Oral-B has had years to perfect the design and manufacturing to limit such.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A number of iO brushes I have been using for several years remain functional with no issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is a need to move to more sustainable approaches. It's disappointing that parts of the brush are not intentionally designed to be user serviceable. Yes, this is common for electric toothbrushes. Although Oral-B doesn't overly promote this, it is possible to replace the battery yourself, as <a href=\"https:\/\/youtu.be\/4dEPyCYw39o\" data-type=\"link\" data-id=\"https:\/\/youtu.be\/4dEPyCYw39o\" target=\"_blank\" rel=\"noreferrer noopener\">demonstrated in this video<\/a>.

This doesn\u2019t mean that you shouldn\u2019t use one. You need to balance effective cleaning and disease prevention against the environmental impact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the additional, non-essential technology built into the iO9, plus the extra accessories, bigger box and increased shipping weight the impact is likely much higher than lower spec\u2019d brushes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While Oral-B has partnered with schemes such as TerraCycle, it does not yet have its own recycling scheme for used brush heads or faulty products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its brush heads are made from petroleum-based plastic, which uses up the planet\u2019s finite resources compared to using plant-based plastics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Come the end of its life the extra electrical components required for the smart technology results in more e-waste.&nbsp;<\/p>\n<\/div><\/div>\n\n\n\n<div id=\"conclusion\" class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Conclusion: fantastic, but you\u2019re paying for non-essential features<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The iO9 is a top of the range brush and one I do recommend.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It isn\u2019t for everyone and even if you can afford the premium price, I will reiterate, you don\u2019t need the extra features. More affordable brushes (see the <a href=\"https:\/\/www.electricteeth.com\/au\/toothbrush\/pro-2500x\/\" data-type=\"toothbrush\" data-id=\"15359\">Pro 1500x<\/a>) clean the teeth just as well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But, if you love your tech and want the best, this is it. For those committed to getting the most from the iO9, it can pick up on your mistakes and encourage you to do better. Used to its full capability, it will help you achieve cleaner and healthier teeth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Just be aware that the battery life isn\u2019t amazing. The tracking isn\u2019t perfect and you\u2019re stuck buying more expensive brush heads.<\/p>\n\n\n            <div  class=\"lg:my-6 my-3\">\n\n                \n                <div
