Philips Sonicare DiamondClean Smart : Features & Benefits

Sonicare has manufactured 4 models of Philips Sonicare DiamondClean Smart electric toothbrush. Which of these should you get?

The answer depends upon your unique needs and the specific features included in each model. Let’s explore them next.

The 4 DiamondClean models are:

Philips Sonicare DiamondClean Smart 9300 Series
Sonicare DiamondClean Smart 9500 Series
Philips Sonicare DiamondClean Smart 9750 Series
Sonicare DiamondClean Smart 9700 Series

All four models share the following features in common:

  • clean through sonic action at 31,000 vibrations per minute
  • operate in 3 modes of intensity
  • have inbuilt timer with quad pacer
  • pressure sensor to avoid injury to gums and teeth
  • automatic power down function
  • Smart travel case that doubles as a recharger
  • battery life is superb (runs for 3 weeks on a single charge)
  • BrushSync technology for replacing brush heads

Apart from these, each of the 4 models has some unique elements that may not be included in another. Maybe these are vital for your needs, which will make one of the models a better fit.

Philips Sonicare DiamondClean Smart - Cleaning Modes

Brushing Modes

All 4 Philips Sonicare DiamondClean models offer a choice of 5 different brushing modes:

  • Clean
  • White+
  • Gum Health
  • Deep Clean
  • Tongue Care (except in 9300 series)

You can switch between them by pressing on a button. In Clean mode, which is the default setting that most users will operate, the toothbrush vibrates at 31,000 strokes per minute to generate a sonic power wave for cleaning. This is effective at getting rid of dental plaque and stains on teeth.

White+ mode allows for a longer brushing session to whiten teeth better. Polish mode is available in some models to remove stains and leave teeth shiny and sparkling.

Gum Care or Health mode is gentle and meant for users with gingivitis, gum diseases and previous dental surgery. It’s a weaker brushing mode and is gentle on teeth and gums.

Color Choices

The Philips Sonicare DiamondClean Smart 9300 is available in a choice of:

  • pink
  • white
  • black
  • silver/gray

Philips Sonicare DiamondClean Smart Review - Multiple Colors

The Sonicare DiamondClean Smart 9500 range comes in

  • pink
  • black
  • white
  • silver
  • rose gold

The other two models are only available in a single color. The Sonicare DiamondClean Smart 9700 series is in lunar blue, while the Philips Sonicare DiamondClean Smart 9750 comes in rose gold only.

What’s In The Box?

All four models of the Philips Sonicare DiamondClean electric toothbrush include:

  • DiamondClean brush handle
  • replacement brush heads (vary in number and type between models)
  • charging station
  • Smart travel case (with recharging function in 9500 and 9700)
  • instruction manual
  • documentation and warranty

Brush Head Storage

In the Philips Sonicare DiamondClean Smart 9750 there is a storage unit in which you can keep up to 4 replacement brush heads. This isn’t available with the other models.

Philips Sonicare DiamondClean Review : Design & Aesthetics

This premium electric toothbrush is a sophisticated and elegant device that comes in an assortment of colors to suit your taste and preferences.

From a daring Lunar Blue to a gentle Rose Pink, there are pastel shades to please a connoisseur.

That an electric toothbrush can almost resemble a piece of art sounds weird. But the Philips Sonicare DiamondClean Smart electric toothbrush does just that.

In keeping with its positioning as a premium product, every element of it has been carefully crafted to appeal and impress.

Replacement brush heads also come in an array of color options to match the handles. There are even travel cases in matching color themes for a co-ordinated effect. You get to pick between a black or white case.

A Cut Apart

Right from the moment you unbox the Philips Sonicare DiamondClean, you’re aware that this is a classy product. The toothbrush feels luxurious to look, feel and hold. Nothing about it is cheap or cheesy.

The arrangement of LED indicators and control buttons is thoughtful and pleasing. In the end, the Philips Sonicare DiamondClean Smart is an electric toothbrush anyone would be proud to own.

The only drawback to consider is that its slick and sleek finish makes the toothbrush feel a bit slippery when it is wet. If there had been some ridges or grooves to get a better grip, it might have been better.

Philips Sonicare DiamondClean Smart Review : Battery Life

All Sonicare electric toothbrushes come with excellent battery life. The Philips Sonicare DiamondClean is no exception to this general rule.

The toothbrush runs on a lithium ion battery. A full recharge lasts for upto 3 weeks of typical use.

The battery that is encased within the brush handle is not meant to be replaced or removed. You can recharge it using the recharging station. It takes around 24 hours to fully recharge when drained.

The automatic power down function helps conserve battery power. At the end of a brushing session of 2 minutes, the motor turns off without you having to do a thing.

The Philips Sonicare DiamondClean Smartphone App

Philips Sonicare DiamondClean Smart review - Smartphone app

Like most premium electric toothbrushes, the Philips Sonicare DiamondClean Smart has a wireless Bluetooth connectivity with a Smartphone app to track and monitor brushing behavior.

The app is compatible with both Apple and Android smartphones and tablets. It displays graphics showing how well your teeth are being cleaned, offering feedback to help avoid missing areas.

It also keeps records of cleaning activity, so you can tell at a glance if you’re brushing regularly. Your dentist also will have evidence to show you’re complying with instructions.

How Does The Smartphone App Work?

While your app is running, the Bluetooth connection transmits data about your brushing session to the app. In real time, you’ll receive feedback about where to brush, and for how long.

As the graphic display demonstrates how your teeth are whitening, it can be a fun way to have younger users get accustomed to the habit of cleaning their teeth. It also helps avoid overlooking quadrants and leading to cavities or other problems.

Data can be stored temporarily on the device itself. But once in 4 weeks at least, it must be synched with the Smartphone app to transfer, otherwise the data will be lost.

The app can also let you know when it is time to replace a brush head because it has worn out.

Philips Sonicare DiamondClean Brush Heads

Sonicare toothbrush replacement heads

Replacing worn out brush heads is necessary once in 3 months or so. This depends largely upon the brushing frequency. Heavier use may need changing the brush head sooner.

Bristles in the Philips Sonicare DiamondClean brush head are shaped like a diamond. The bristles are densely packed, and aligned at angles suitable to remove debris and plaque from crevices between teeth and behind last molars.

The brush heads are available in two sizes – regular and compact. Both are excellent at creating the power wave which ensures cleaning even at a distance from the brush head itself.

Brush heads with BrushSync technology can track usage and notify you when it is time to change it. Replacement brush heads are readily available and can be simply snapped on to the same handle.

These ‘smart‘ brush heads have RFID chips embedded in them to mode-pair with the handle and send reminders about changing heads before they lose efficiency.

The cost of such Smart brush heads is slightly higher. Philips Sonicare DiamondClean heads cost around $15 each and come in packs of two or four heads. Larger packs offer discounted rates.

Is The Philips Sonicare DiamondClean Good For Travellers?

Philips Sonicare DiamondClean Smart - Travel Case

Yes, the inclusion of a premium travel case in the package makes this an ideal electric toothbrush to conveniently carry along on trips.

The case has a shell of hard plastic covered with soft leather. It looks classy and stylish while serving the purpose of protecting the delicate instrument inside.

The travel case can comfortably hold the toothbrush, spare replacement heads as well as the recharging cable. It snaps shut with a magnetic holder, requiring no buttons or clips to hold it closed.

The Smart travel case allows recharging while being stored. A 2 foot long cable can be detached and carried along to attach to a power outlet also through a Type A USB connection. But since a full recharge will last you for 2 to 3 weeks of regular use, this may not even be necessary for most trips.

Are There Any Drawbacks To The Philips Sonicare DiamondClean?

Switching between brushing modes can be a bit non-intuitive.

To reach Sensitive mode, you will have to cycle through all other modes first. This means you’ll press the button five times until you can arrive at the desired cleaning mode.

There’s a problem here – because the motor turns on while this is happening. If you are already brushing while you switch modes, this can lead to toothpaste and spittle splattering all over.

The only other complaint voiced by some owners on consumer forums is about the occasional battery failure. This seems to be due to defective items being shipped out rarely. The manufacturer has promptly replaced them at no cost.

Is The Philips Sonicare DiamondClean Electric Toothbrush Worth Buying?

While this is the most important question any Philips Sonicare DiamondClean review has to address, it’s also the most difficult because your mileage will vary.

If you are happy with your current instrument, there’s little reason to switch over to the more elaborate DiamondClean unless some of its features appeal to you. On the other hand, it is an excellent device to upgrade to, especially if you’re lucky to get a good deal.
