    Overview

    The Philips Sonicare DiamondClean 9000 (HX9914/75) is the pinnacle of sonic toothbrush design, delivering exceptional cleaning power, advanced personalisation, and elegant style. Engineered to remove up to 20x more plaque than a manual toothbrush, it comes equipped with the A3 Premium All-in-One brush head, designed to lift up to 100% more stains in under two days and improve gum health up to 15x in just two weeks — all without switching heads.

    Its four custom modes (Clean, White+, Gum Health, Deep Clean+) and three intensity settings let you tailor every brushing session to your needs, whether you’re chasing that perfect white smile or prioritising deep gum care. The built-in smart sensors and Bluetooth connectivity sync with the Sonicare app to track your brushing, providing personalised guidance, real-time feedback, and progress reports that help you build healthier habits between dental checkups.

    The DiamondClean 9000 doesn’t just clean — it transforms your brushing experience. A gentle pressure sensor protects your gums, while smart brush head recognition and BrushSync ensure you’re always brushing at peak performance. Wrapped in a sleek, modern design and paired with a convenient travel case, it’s the ultimate oral care companion for a whiter, healthier smile that lasts.
    A3 Premium All-in-One Brush Head

    Angled bristles remove up to 20x more plaque, triangular tips lift 100% more stains in two days, and longer bristles clean deep for gums that are 15x healthier in just two weeks — all without swapping heads.

    Four Cleaning Modes + Three Intensities

    Personalise your brushing with Clean, White+, Gum Health, and Deep Clean+ modes, paired with adjustable intensity settings that let you choose a powerful deep clean or a gentle touch for sensitive areas.

    Connected Smart App + Progress Reports

    Bluetooth connectivity links to the Sonicare app, providing personalised brushing feedback, habit coaching, and progress reports that help you improve technique and track your oral health journey over time.

    Smart Sensors + BrushSync Technology

    Built-in pressure sensors protect your gums by alerting you when brushing too hard, while BrushSync recognises brush heads, adjusts settings accordingly, and reminds you when it’s time to replace.

    The electric toothbrush provides an effective cleaning experience with its multiple brushing modes and intensity levels. It is gentle on gums and has convenient features like wireless charging and Bluetooth connectivity. However, some users have reported issues with the toothbrush's durability and the mobile app's limitations. Overall, it offers a superior cleaning performance, but the high price and potential reliability concerns are important factors to consider.

    Superb handle with gorgeous accesories
    [This review was collected as part of a promotion.] This is a superb toothbrush. As a longtime sonicare customer, I have owned similar models but this has been my first top-of-the-line/ bluetooth-enabled toothbrush handle. All I can say is that I am very impressed, the glass cup charger, the USB charging travel case, app-enabled brush modes, and just general tutorials and tips for use have made me realized I am just now learning to use my sonicare properly. The built in timer is much more intuitive when you brush without the app on this model, as it separates the sections in your mouth more clearly. Loved the glass charging base, it is very cool and looks great on the countertop when it has to charge, around twice a month. I have found switching the brush modes on this model is way more satisfying too, and I use more of them than just the simple clean setting.

    Efficient Cleaning
    Never before have my teeth felt as clean as when leaving a dental hygienist from just using a toothbrush. This Sonicare product is exceptiional.

    Great toothbrush
    The toothbrush does a great job cleaning your teeth and they certainly feel cleaner after brushing, definitely cleaner than my previous (not a Philips) toothbrush. It seems rather loud whilst brushing but is quite tolerable. The charging glass is a great idea and works well, just drop it in (gently) and it’s charging. Battery seems to last ages. The only problem I have had so far is the app, while being a helpful guide, is completely useless. It can’t find the brush handle and I have had to download and delete it a couple of times. It recognises the handle and one or two brushes later can’t find it, so repeat process. Then repeat again! Until you get sick of it and give up. So the point is to keep a record of your brushing habits, but it cannot do that when it can’t find the brush. It looks like I brush every two or three days.
