The toothbrush has a superb cleaning result. The battery doesn’t last as long as my old cheaper electric toothbrush and the replacement heads are a little pricey. I guess if you want a really good cleaning, I have to pay for the OEM replacement heads
[This review was collected as part of a promotion.] I have purchased a few Phillip Sonicare toothbrushes over the past. Recently, I purchased DiamondClean 9000 HX9911 in January 2026 and had trouble getting it to work until April 2026 at which point I contacted Phillips Sonicare and they exchanged my defective DiamondClean 9000 HX9911 with a new one which works!
