Our recommendation
Buy the Oral-B iO Series 7 if you like a small head guided tooth by tooth, want a display and app tracking, and will use the feedback. Buy the Philips Sonicare ProtectiveClean 6100 if you prefer a familiar brush shape, a gentler sonic feel, and a lower price with no app to manage. Both protect with pressure sensors; technique fit is the tiebreaker.
Cleaning action and head shape
The iO 7 uses a small round head with magnetic micro-vibrations that cups each tooth and rewards a slow, tooth-by-tooth path. The 6100 uses an oval sonic head that sweeps like a manual brush while driving fluid between teeth. People with braces, crowns, or tight back molars often prefer the small Oral-B head; people who brush fast often prefer Sonicare.
Feedback and controls
The iO 7 has an interactive display, a light-ring pressure signal, and six-zone app tracking. The 6100 has button controls, a pulsing pressure warning, and BrushSync head reminders, but no app. The Oral-B tells you more; the Philips asks less of you.
Running costs
iO heads are proprietary and sit at the premium end of refill pricing. Sonicare standard heads cost less per head and go on sale in multipacks often. Over three years the 6100 is the cheaper brush to own, widening its upfront price advantage.

Choose Philips Sonicare ProtectiveClean 6100 if…
- You prefer a gentle sonic feel and a familiar head shape

- Lower handle and refill costs matter more than tracking

Strengths and limitations
Oral-B iO Series 7 Deep Clean + Protect
Strengths
- Same magnetic iO drive and round-head micro-vibration clean as the flagship, with five personalised modes selected on an interactive display.
- The Oral-B app tracks brushing in real time across six zones and coaches coverage, which catches the commonly missed back molars.
- A three-hour fast charger and charging travel case solve the two classic electric brush annoyances: dead batteries and travel bulk.
Limitations
- App tracking covers six zones rather than the 16 zones of the Series 9 and 10.
- Still a premium handle, and iO heads remain pricier than classic Oral-B refills.
- The display adds a small learning curve compared with one-button brushes.
Philips Sonicare ProtectiveClean 6100
Strengths
- Three modes (Clean, White, and Gum Care) each with three intensities cover the routines people actually use, including a stain-focused White mode Philips positions for visible whitening in a week.
- A pressure sensor pulses and reduces vibration when you press too hard, and BrushSync tracks head wear so replacements happen on time rather than by guesswork.
- Two-week battery life and an included travel case make it an easy travel companion at this tier.
Limitations
- No Bluetooth or app, so there is no coverage feedback beyond the timer and pacer.
- Ships with a single W DiamondClean head, so budget for refills sooner than multi-head kits.
- Handle finish and accessories feel a step below the DiamondClean line.

Made your call?
Questions, answered
Which is better for braces?
Both work with the right heads, but the small round Oral-B head is easier to angle around brackets and wires tooth by tooth. Ask your orthodontist which head they prefer for your appliance.
Which is quieter?
Sonicare, clearly. The ProtectiveClean 6100 is a low hum next to the iO's mechanical buzz, which matters in shared bathrooms and early mornings.
