Philips Sonicare 1100 Series review

Philips Sonicare 1100 Series review 1

A simple entry-level brush, but there’s a better option


The Sonicare 1100 is a great electric toothbrush.

Easy to use, it offers a good clean of the teeth as well as satisfactory battery life.

The biggest downside is that it lacks a pressure sensor, which is a useful feature for preventing you from brushing too hard.

The 2100 is the same spec but better value

£49 is about what you’ll pay for the 1100. That’s a small discount on the £59.99 retail price.

Replacement brush heads cost around £6 each. This makes the 3 year ownership total about £115.

Buy the 2100 series instead. Generally cheaper by about £15, it comes with a different brush head, but it is otherwise the same. It’s our best budget Sonicare toothbrush.

But we do encourage you to take a look at our ‘best overall’ choice from Oral-B, the Pro 3 3500.

It has the essential features of a good electric toothbrush and it is affordable. It ticks the boxes the 1100 Series doesn’t — a travel case and a pressure sensor. It isn’t as refined as Sonicare handles, but it cleans comparably and packs a punch for the price.

One button, one mode: it’s all you need to achieve clean teeth

Simple and less complicated is often better. The 1100 is just this. 

A single press of the button on the handle is all that is needed to get brushing.

The concave rubber button is easily detected with the power icon embossed on it. Not too firm, each time it is pressed you get reassuring feedback including a clicking noise.

The ‘Clean’ mode is perfectly sufficient for the vast majority of users.

Lasting for 2 minutes the sonic brush head gives a good overall clean. I am perfectly satisfied with the results. 

Different styles of Sonicare brush heads are available and compatible with the 1100 Series. The provided C1 SimplyClean or S Sensitive (subject to variant) are great options for everyday cleaning. You don’t need to worry about getting a specialised head to whiten the teeth for example. 

BrushSync technology that alerts you when to replace your brush head is not available on the 1100. This is reserved for the 3100 Series and other premium brushes. You’ll need to remember to replace the head every 3 months.

If you have a small mouth, a sonic toothbrush might not be right for you. The oval heads tend to be larger than the oscillating-rotating counterparts from Oral-B.

It’s less powerful than most sonic brushes but still cleans well

The motor that moves the bristles of the brush head is tuned differently to the motors found in premium Sonicare models. It doesn’t achieve the 62,000  movements of some of Sonicare's more expensive brushes.

It means the 1100 doesn’t offer quite the same intensity and deep clean feeling when in use. But, unless you have used a Sonicare toothbrush before, you’d have no reason to question it. The sonic vibrations give a thorough and clean feeling.

Cleaning results are not impacted. They are most definitely comparable. 

It does appear to make the brush quieter in use. It’s audible hum is just 57 decibels. Quieter than many other sonic brushes, great if you don’t want to disturb others.

It’s got a 2 minute timer and pacer to help you brush evenly

If you turn the 1100 Series off yourself, you haven’t brushed for long enough. This is because it turns itself off automatically when the 2 minute cleaning cycle is complete.

With average brushing times being just 45-70 seconds per day, the timer is a great motivator to brush for longer for the benefit of your oral health.

Maximum benefit is gained when you brush all the tooth surfaces evenly. A pacer built into the 1100 will at 30 second intervals pause the bristle motion. Creating a change in sound and brushing sensation, this is your cue to move between the 4 sections of the mouth until all have been brushed.

The timer and pacer are 2 essential features of any good electric toothbrush.

It lacks the protection of a pressure sensor

The 1100 Series does not have a pressure sensor built in. This means that you are not alerted in any way should you scrub the teeth too hard as you brush. Forceful brushing will in the long term damage teeth and gums.

Pressure sensors often don’t feature in the cheapest of toothbrushes. You don’t need it to brush your teeth well, but it's a dentist recommended feature. More brushes now do include them than in times past. If you know you like to brush hard and fast you should seriously consider the 3100 Series, which has a pressure sensor.

Slim and stylish

I’ve handled brushes more expensive than this that look and feel worse.

Durable and quality feeling in the hand

It isn’t a perfect cylinder, instead, there is slight squaring to the edges that makes it feel more secure in hand. Given the lack of different textured surfaces, this is welcomed.

Slimmer and lighter (98g) in the palm than previous cheap Sonicare brushes it’s pleasant to use and doesn’t result in the same arm fatigue you might get with other heavier handles.

Available as a white coloured handle only the matt finish to the plastic is resistive and more pleasing to the eye than the glossy finish of many competitor's products.

The 1100’s handle is easy to keep clean and because it is water resistant, can be rinsed under the tap or used in the shower if you prefer.

A firm squeeze of the handle doesn’t result in any dubious sounding creaks or groans from the plastic. It feels well made and looks good.

Daily usability is improved as the toothbrush can stand upright on a countertop and has been designed not to roll too much when laid flat.

The 2 week battery life is adequate but not amazing

A rechargeable Lithium-Ion (Li-Ion) battery is sealed inside the 1100’s handle.

Philips claims 14 days of use on a single charge, but I’ve been able to achieve a respectable average of 17.

Premium Sonicare models often deliver even better usage times, more in line with the 3-4 week average. The poorer performance here isn’t a deal breaker unless you travel or are away from power regularly.

The benefit is a slim handle and a battery charge notification LED. Not always available on affordable toothbrushes it gives you an alert when the brush needs charging.

USB charging makes it more difficult for some

Recharging takes a maximum of 24 hours on the supplied stand.

A new slimmer, circular design, there is a 110cm USB cable hardwired into the stand. It doesn’t have nor come supplied with a 2 pin power adapter to connect it to a shaver socket.

Excluded for environmental reasons, this makes it less convenient for many. Unless you source an adapter (they are not readily available), you will have to charge it from another socket in your home. You’ll need to make use of a 3 pin USB adapter. You probably have one you use for your smartphone or powering other gadgets.

Increased versatility is enabled though as being allows the brush to be charged from a computer, battery bank or USB wall socket if you choose.

2 year warranty included as standard

An industry average 2 year warranty against defects and workmanship is provided. It’s not quite as good as the up to 3 years Oral-B offers with their brushes.

Budget brushes like the 1100 can often come with compromises. Thankfully reliability doesn’t appear to be one that applies. It seems well built with no reason to suggest it wouldn’t last a good few years.

Disappointingly, in an era where environmental impact is important, the 1100 has no serviceable parts. There is no ability to undertake a repair without rendering it useless.

Environmental impact

Electric toothbrushes have an impact 11 times greater than a manual brush on average.

The 1100’s impact is likely to be similar to the average electric brush, as it doesn’t boast lots of extra resource hungry features such as RFID enabled brush heads and smart technology. Impact is further reduced by excluding a 2 pin power adapter. But at odds with this is the lack of repairability and the fact that the handle and stand come wrapped in plastic.

Where some manufacturers now use plant based plastics, Philips heads primarily use petroleum based, thus using more of the finite resources,

Philips has partnered with schemes such as TerraCycle to recycle consumables such as heads, but using this facility isn’t always easy. 

Conclusion: simplicity at a cost

If you are on a budget and want a toothbrush from a leading brand, the 1100 Series is a good choice.  

It looks good and cleans the teeth well. The main downside is the lack of a pressure sensor.

I’d pick the 2100 Series though. Aside from the brush head supplied it is the same brush and typically about £15 cheaper. It’s our choice for a Sonicare toothbrush on a budget.
