Frequently Asked Questions - SONICARE DIAMONDCLEAN 90000 HX9911 - SONICARE DIAMONDCLEAN 90000 HX9914 PHILIPS

Can I leave my Sonicare toothbrush on the charger permanently?
Yes, you can leave your Philips Sonicare on the plugged-in charger permanently. This does not affect battery life.
How often should I replace the brush head?
We recommend replacing the brush head every 3 months or sooner if the bristles are worn. The replacement light will flash orange when needed.
Which brush heads are compatible with my DiamondClean 9000?
All Philips Sonicare brush heads fit, but the smart heads (C3, W3, G3) offer BrushSync features like automatic mode and replacement reminder.
How do I use the Sonicare app with my toothbrush?
Download the Philips Sonicare app from the App Store or Google Play, enable Bluetooth on your phone, and follow the pairing instructions. The app lets you track your brushing and receive personalized tips.
What should I do if the pressure sensor triggers too often?
The pressure sensor alerts you when you brush too hard. If this happens often, reduce the pressure you apply. You can disable this function by pressing and holding the on/off button for 7 seconds (see the manual).
What is the EasyStart function?
The EasyStart function gradually increases brush power over the first 14 brushings to ease you in. It is disabled by default: you can enable it by pressing and holding the on/off button for 3 seconds.
How do I clean my Sonicare toothbrush properly?
Remove the brush head and rinse it with warm water. Clean the handle with a damp cloth, especially the connection area. Never put the handle or charger in the dishwasher and do not use alcohol, vinegar, or bleach.
Can I use the travel case to charge my brush?
Yes, the travel case (depending on the model) allows you to charge your brush via a USB port (5 V DC). Plug the provided USB cable into a certified wall adapter or a computer USB port.
How long does the battery of the DiamondClean 9000 last?
A full charge (24 hours) provides about 2 weeks of normal use (two 2-minute brushings per day). The battery depletes gradually, and a flashing orange light indicates it needs charging.
Does the warranty cover brush heads?
No, the international warranty does not cover brush heads (considered consumables). It covers manufacturing defects of the handle, charger, and case for 2 years.
