Philips Sonicare 1100 Series Review

Design, usability, clean & general use

If you have ever seen and used a Philips Sonicare toothbrush, everything about the 1100 is typical Sonicare.

This is a good thing.

Many elements of the Philips Sonicare toothbrush are excellent and I think the word understated best describes a lot of the Sonicare brushes, the 1100 included.

The retail packaging isn’t the most eye catching, but it does what it needs to.  It explains the key features and what you get included.

It might sound a bit ridiculous to compliment a box for highlighting the product inside, but believe it or not, many brushes have very little information on what the product inside actually offers. This is fine if buying online, but not quite so good for the shop shelves.

Another nice touch is the image on the box is colour matched to the handle inside.

Like many companies, Philips is taking a bit more of a proactive stance with their packaging to ensure it is more sustainable.  The outer box and inner tray are made from cardboard. 

As I will explain in more detail later, Philips has now even changed their conventional charging stand to reduce plastic use.

It is then a little disheartening to find the brush head, handle and charger are all wrapped in plastic.  It is LDPE 4 plastic, which can technically be recycled, but it is still fairly difficult to do for most people.

I perhaps understand the brush head, but the stand and handle, is this really required?  How much more plastic could be saved by dropping these.  Other manufacturers don’t.

Right, to the toothbrush itself then.

The 1100 isn’t breaking any new ground with revolutionary design and innovation.  And this is a good thing.

It is made up of 2 key parts, the brush handle and the brush head.

The handle of the 1100 is nice and slim.

It is much slimmer than some older and cost effective models like the DailyClean toothbrush handles.  

In fact, the 1100 is one of a number of brushes that have benefited from a slight redesign.  The result is a slimmer and lighter handle.  Others include the 2100 and 3100 series.

The handle measures about 2.6cm wide and thick.  And in hand, with the brush head fitted it weighs just 98g.

It isn’t the absolute lightest electric toothbrush, but it is a good few grams lighter than some other models and it is noticeable.

At the time of review, the 1100 is available in 2 colour options.  In both instances the handle colour is white, it is just the power button colour that differs.  One is grey whilst the other is mint green.

The handle has a matt white finish to it, rather than a gloss white, I approve of this.  It is accented by the one and only button on the handle.

The handle isn’t a perfect cylinder. There is a very slight squaring off to the body which does result in a comfortable and nice to use handle.

Aside from the silicone power button, the handle is smooth to the touch.  It makes for a very clean and minimal looking toothbrush.

For some, it might be a bit slippy in hand.  But, somehow the finish to the body means it doesn’t actually feel slippy, despite not having raised surfaces or different textures to grip onto.

Ultimately the handle feels solid, well built and durable for the price paid.

On the front of the handle, just below the metal shaft to which the brush head attaches, is the Philips Sonicare logo, in a grey coloured font.

Beneath this, within the upper third of the handle, is a subtle contouring to create an elliptical shape.  Inside this is the power button. It appears to have an almost seamless design, despite being silicone, compared to the plastic of the brush handle itself.

The round button has a concave shape and power icon embossed on it. There is good clicky feedback to it and as it isn’t very firm, it’s quite easy to activate. Great for those with limited dexterity.

The implementation of the button and contouring results in a space on the handle that becomes a natural resting place for the thumb when in use.

The only other meaningful item on the handle is the battery status LED in the lower third of the handle.

The LED sits above a battery icon.

Different coloured lights and patterns are emitted from this LED subject to the status of the built-in rechargeable battery.  I have listed these in the battery life section of this review.  

The sides and back of the handle are free of controls.  

The only other small thing worth mentioning is on the back of the handle, towards the very bottom are 2 raised bits of plastic on the handle.  These are there to prevent the toothbrush from rolling when laid on a flat surface.  Genius.

The toothbrush will stand upright.  The base of the handle is flat, but it does have a recess for the pin on the charging stand to fit into.

Printed on the base is the model number along with some regulatory information.

The top of the handle tapers in very slightly, just before flattening out to give a surface for the brush head to sit on. 

In the middle of this flat surface, extending out upwards is a metal shaft that connects to the brush motor inside the handle.

The provided Simply Clean brush head simply pushes onto and pulls off of this. There is no need to twist or lock any head in place.

Once fitted, if you take a look at the handle from the side, the head sits perfectly vertically. There is no angling of the brush head as is the case with some other models.

I feel it is worth pointing out at this stage that the Simply Clean brush head is one of a number of different options on offer from Philips. It isn’t the most commonly offered head either.  All the different choices are listed in our Sonicare brush heads explained article.

But the key thing to be aware of is that whilst the vast majority will fit and work with the 1100, the BrushSync enabled heads will not be tracked.

The vast majority of heads on offer now have BrushSync technology, but this handle does not support this.

You can gladly use the BrushSync enabled W3 Premium White if you like, just know the 1100 is never going to tell you when to replace the head.

You can save yourself a few pounds by opting for those heads that don’t have an RFID chip built-in.  This includes the C1 SimplyClean, S Sensitive and the C1 ProResults. Although be aware even the ProResults is in the process of being upgraded.

If you want a handle that tracks your brush head, you need to look at more premium models such as the 3100 and 4300.

Subtle differences in cleaning results do exist between the brush heads, but more significant improvement will be gained from improving your brushing time and technique than picking one particular brush head.

The supplied SimpleClean head is a great everyday brush head with a W profile to maximise the cleaning ability of the brush. It cups the teeth and cleans deep between them too.

You should replace the head on average every 3 months.  Whilst the handle itself won’t remind you, bristles on the head do fade to act as a visual reminder to you to do so.

Be sure to recycle your brush heads when done with them.  We explain your options here.

The 1100 has just one cleaning/brushing mode.  

This is in truth all that the vast majority of us need.

It makes it nice and simple to use.

Yes, potentially there are benefits from different cleaning modes, but the vast majority of users don’t require these.

If I was going to pick any one extra mode, it would be a slower and more gentle sensitive mode.

This is great for those with sensitive teeth and gums, but also great for new toothbrush users, to ease them into the increased power that these brushes offer.

Although the 1100 doesn’t offer a second mode, it does have you covered with its Easy Start feature.  This limits the full power of the brush over the first 14 brushing sessions to help make the transition for new users easier.

The default cleaning mode lasts for 2 minutes.  The brush automatically turns itself off when 2 minutes have elapsed.  This is a very clear indicator that the recommended brushing time has been achieved.

As the brush powers on the timer and quadpacer are activated.

As the bristles move the timer counts and once it hits 30 seconds, it pauses the brush motor briefly.

This pause changes the sound and brushing sensation. It is your alert to move from one quadrant of the mouth to another.

This then repeats every 30 seconds, until the brush gets to 120 seconds (2 minutes) at which point it will turn itself off.

If you are not familiar with the concept of quadrant and 30 second intervals, allow me to explain.

Whilst dentists recommend 2 minutes of cleaning twice a day, what this does not help with is ensuring you and I brush our teeth evenly. 

The idea is that you break the mouth up into 4 sections: 

• upper right
• upper left
• lower right 
• lower left

You spend 30 seconds cleaning each section. As you do, you try and give equal attention to the front, back and biting surfaces of the teeth. If you do, come the 120 seconds (2 minutes) of brushing time, you should have achieved an even clean to the teeth and gums.

The pacer acts as an alert to you, to change the quadrant as you brush to encourage this even clean.

Of course, you don’t have to follow it, but it is good practice.

When brushing your teeth, the bristles need only really skim the surface of the teeth. You need just a little bit of pressure, not lots. Too much pressure can cause wear on the teeth and gums and in the long term result in irreversible damage.

Many toothbrushes have a pressure sensor built-in to alert you when you are brushing with too much force.  It is one of the key features we recommend looking for in a brush.

Unfortunately, the 1100 doesn’t have one.  This means you won’t be alerted if you brush too hard. Do your best to avoid damaging the teeth and gums and brush with little force.

Something to be aware of is the power of the brush motor in the 1100 isn’t the same as that used in the more premium Sonicare models.

The 1100 motor does offer up to 31,000 brush strokes, but it doesn’t achieve the 62,000 movements often quoted with the more expensive models. It is configured differently.  

As a result, the 1100 does feel less powerful/intense compared to some other Sonicare toothbrushes.

Technically, more power or movements does mean better cleaning results.  But, it isn’t quite as simple as this, there are more factors at play.

The lesser power on offer here isn’t immediately obvious. Even for me and I have tested hundreds of brushes. The brushing sensation is slightly different. It is most noticeable if you have used other premium Sonicare toothbrushes before.

The 1100 still does a very good job.  My teeth feel clean after each brushing session. It is just a bit of a shame that you are not getting the ultimate Sonicare cleaning experience.

For first time users of an electric toothbrush this isn’t a deal breaker on its own, but something to be aware of.  Even for existing Sonicare users, don’t get too hooked up on this point.  The implications are not as great as you might think.

Your technique and brushing time will likely have more impact on your oral health than the number of bristle movements.  

If you want to ensure you are doing the best by your teeth, view our helpful guide that explains the correct ways to brush the teeth.

Sealed inside the 1100’s brush handle is all the technology that makes this brush function, which includes the user rechargeable, but not user replaceable lithium-ion battery.

The handle is water resistant, which means toothpaste, saliva and water shouldn’t pose a reliability issue. A rinse under the tap to clean it is fine. Sonicare tends not to advise use when bathing, but I know many do brush their teeth whilst in the shower. The important thing here is to avoid full submersion in water.

At this time the 1100 doesn’t come supplied with a travel case which is a bit of a disappointment.  It can be useful to own one of these to protect the handle and brush head when on the go.

You can buy cases from Philips or find third party alternatives for a few pounds.

And lastly, Sonicare does offer a 2 year warranty that covers any mechanical or workmanship faults, but not user damage.
