KEY SPECS
- Model: Oral-B iO Series 7 — Deep Clean + Protect bundle, Black (part P_7082)
- Cleaning modes: 5 — Daily Clean, Sensitive, Whitening, Gum Care, Intense Clean
- Smart pressure sensor — warns when you press too hard or too soft

- 2-minute timer with brush-head change alert (every 3 months)
- Battery: up to 2 weeks per charge · 3-hour fast charger

WHY THIS PICK
- The Series 7 combines Oral-B's magnetic iO drive, round brush head, and smart pressure sensor with five brushing modes and app-based guidance.
- Five modes plus app coaching that shows the spots you missed — the guidance the cheaper iO brushes leave out
- Nothing else to buy to start: two brush heads and a charging travel case are in the box, and one charge lasts up to two weeks
HONEST NOTE
At $229.99, Series 7 costs $120.00 more than the Amazon Series 3 option. You're paying for added features and the listed bundle contents, not just the brushing handle. If you won't use the display or app coaching, Series 3 may be the better value. Replacement iO heads are an ongoing cost either way — Oral-B recommends a new head every 3 months.
+α THE VALUE OPTION
Nearly the same performance as the compared pick — for much less money.

MAIN FUNCTIONS
- The same iO magnetic drive and round brush head as the Series 7
- Smart pressure sensor and 2-minute timer — the guidance basics are kept
- Takes the same iO replacement heads as the flagship — one head type for the whole line
THE TRADE-OFF
No display, no app coaching, three modes instead of the flagship's five. The Series 7 travel case also charges the brush; the Series 3 case is protective only.
Note: Target sells a leaner Series 3 box (1 brush head) from $89.99 — a different bundle, so compare box contents as well as price.
WHO SHOULD BUY WHICH
The Series 7 is for the person who wants a coach: five modes, an app that maps your brushing, and a travel case that charges. Buy it if data and gadgets keep you honest. Buy the Series 3 if you want the same iO magnetic drive and round brush head without the homework — same iO motor and sensor doing the work every morning, none of the screen time. It is also the easier second brush for a spouse or a travel bag.
