The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the DiamondClean 9000 is Philips' flagship app-connected brush, and the high-trust source electricteeth.com says it 'cleans the teeth really well' with little to complain about, leaving the mouth feeling clean and fresh after each use. techradar.com adds that it runs fairly quietly even at its highest intensity, about as loud as a typical oscillating brush. The app, 12 brushing settings, pressure sensor and replacement-reminder system are the headline smart features.

Across the reviewers we read, the DiamondClean 9000 is Philips' flagship app-connected brush, and the high-trust source electricteeth.com says it 'cleans the teeth really well' with little to complain about, leaving the mouth feeling clean and fresh after each use. techradar.com adds that it runs fairly quietly even at its highest intensity, about as loud as a typical oscillating brush. The app, 12 brushing settings, pressure sensor and replacement-reminder system are the headline smart features.
Verified-purchase and community sentiment is more measured. Amazon's 4.2 average across roughly 2,200 reviews is good rather than exceptional, and r/BuyItForLife users who compared it to cheaper Sonicares noted the premium model is quieter with better battery life and a smoother, 'glass-like' finish, but several questioned whether the app and extra modes justify the price.
The most serious recurring complaint comes from r/BuyItForLife durability threads: multiple users report power-button failures within 12-18 months on newer Sonicare handles because the housing isn't sealed as well as older models. If you want the full Philips smart-app experience, this is the model to get, but treat the price premium and durability reports with eyes open.

I bought my Sonicare in 2012. It has lasted me up until now. I dropped it while brushing in the shower the other day, now it's starting to die.
Sonicare has significantly better battery life (no idea why), is quieter, and seems to leave my teeth just a bit smoother and glass-like than the Oral B seems ...
