This is a great product

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!

Very happy with my new DiamondClean toothbrush

I really like the new DiamondClean toothbrush. I have used SonicCare toothbrushes for years and the DiamondCare is a step above those. I love the little glass battery as opposed to the SonicCare battery holders.

Pros

Easier to use smaller brush, easier to hold smaller handle, easier to insert brush

Cons

No cons for me—all pro comments

Love this toothbrush!

I've been using Sonicare/InterPlak for decades. This DiamondClean Smart toothbrush lasted 5 years! Unfortunately, I had to order a new one because the spindle became loose and vibrated terribly. It was just a matter of time before it came off completely. I definitely feel I got my money's worth since it lasted 5 years. Just ordered my replacement.

Pros

Love the deep clean feature.
