Thorough cleaning is the strongest theme: pack of 4 of 5 hands-on reviewers praise it, and 17% of owners mention good cleaning. 4 reviewers call its position tracking very accurate. The downsides come up repeatedly too. 3 of 5 hands-on testers found it aggressive on gums and 3 called it loud. 12% of owners complain about the app, and 14% mention a failure, including 6% whose brush broke or died. Retail scores are strong, at 4.5 stars across 2,239 Google votes, but the long-term reliability evidence is thin.
What each expert concluded
The Genius X cleans excellently, but it is rough on gums, loud, and flawed in most other areas, so the reviewers can't fully recommend it at its price compared with better rivals.
Hands-on review · open the review ↗4/5A sturdy, well-designed smart-ish electric toothbrush that cleans thoroughly with or without its app, tracks brushing position very accurately, and comes with an excellent travel case, though it is loud and a poor fit for sensitive gums.
Hands-on review · open the review ↗The Genius X cleans just as well as the pricier Oral-B iO and has real-time tracking, so it's a good-value choice if you can accept a less sleek design, a louder motor and much slower charging.
Hands-on review · open the review ↗A premium electric brush with the most accurate mouth-zone tracking the writer has tested and useful end-of-session feedback, held back by a bulky dated design, fiddly app syncing, poor multi-user support, and overstated AI marketing.
Hands-on review · open the review ↗The writer was impressed by how accurately the AI tracked brushing position and flagged excess pressure, found it intuitive and effective, and accepted the high price as worthwhile for oral health, though long-term results are still pending.
Hands-on review · open the review ↗The visible text only describes the Genius X 10000's features, such as a timer, pressure sensor and optional coaching app, while the actual lab ratings are locked behind a paywall, so no real conclusion is given.

The no-fluff verdict
This is a sturdy smart toothbrush that gets your teeth really clean and tracks where you've brushed with impressive accuracy, with or without the app. The travel case is a real highlight. The catch is that it's loud and can feel rough on sensitive gums, and the app can be finicky. It suits people who want a deep clean and coaching on their technique more than a gentle, quiet brush.

Questions people actually ask
Which is the best Oral-B electric toothbrush, the Genius X or the iO?
It depends on your budget and how much you value comfort. The Genius X cleans about as well as the pricier iO and uses cheaper heads, but the iO is quieter, sleeker, and charges faster.
Based on: Electricteeth and TechRadar compared it directly with the iO.How do you use the Oral-B Genius X electric toothbrush?
Pick a mode with the side button, then brush while the built-in timer and pressure light guide you. You can't switch modes while it's off, so turn it on first.
Based on: Hands-on reviewers describe six modes, a two-minute timer, and the pressure light.Do you need the app to use the Oral-B Genius X?
No, it works fine on its own. The handle still times you, warns you about pressure, and pulses at each zone. The app adds position tracking and a score.
Based on: TechRadar and Forbes note core features work without the app.How do you clean the Oral-B Genius X electric toothbrush?
Wipe the rubber grip sections regularly, because grime builds up there. The charging base has no removable cover, so give it a quick wipe-down too.
