Philips Sonicare models compared: DiamondClean 9000, Smart and Prestige

In its favour

• SenseIQ adapts the intensity to your brushing style, according to Philips, with pressure feedback that glows green when pressure is right.
• Coverage feedback glows blue for finished areas, and the handle display shows post-brushing feedback on spots you missed.
• The box includes a Prestige charging travel case plus a charging base and glass, so home and away charging are both covered.

Good to know

• Only one A3 All-in-One brush head comes in the box, so you will need to buy spares sooner than with multi-head sets.
• The listing gives no battery life figure in days, which matters if you plan to rely on the travel case for long trips.

In its favour

• SenseIQ lowers the intensity when you press too hard, according to Philips, and the light ring flashes as a pressure warning.
• Five brushing modes and three intensity levels give a wide range of settings, from gentler to stronger brushing.
• The set list includes four A3 Premium All-in-One heads, a charging travel case and a charging stand.

Good to know

• There is no handle display on this generation, so coverage and session feedback live in the Sonicare app instead.
• The listing does not state battery life in days or the bristle movements per minute.

In its favour

• Two handles in one box, each with an interactive display, 7 modes and 3 intensities for 21 settings.
• Smart coverage feedback glows blue for finished areas and pressure feedback glows green when pressure is right.
• Philips lists a 2-year limited warranty and a 100-day money-back guarantee on this set.

Good to know

• No travel case is listed; the set comes with a charging base with stand and a charging base with glass.
• A two-handle pack is more than a single person needs, and the listing gives no battery life figure.

In its favour

• Philips lists 62,000 bristle movements per minute with four modes and three intensity levels.
• Four W2 Optimal White heads come in the box, more than most premium sets in this range.
• A USB charging travel case is included, and the handle pulses slightly as a pressure reminder.

Good to know

• There is no brush head detection or SenseIQ, which the DiamondClean and Prestige models add.
• The listing does not state battery life in days, so the case is your backup on longer trips.

In its favour

• Four brushing modes and three intensity levels, with a light ring on the handle that flashes if you press too hard.
• The box includes two heads (A3 Premium All-in-One and G3 Premium Gum Care), a charging glass and a USB charging travel case.
• Brush head detection is listed in the title, and the handle connects to the Philips Sonicare app for brushing guidance.

Good to know

• The listing does not give a battery figure in days, so you cannot plan trip length from the page alone.
• There is no SenseIQ automatic intensity reduction here; that feature is reserved for the Prestige models in this range.

In its favour

• Philips states up to 62,000 bristle movements per minute and up to 14 days of regular brushing on a full charge.
• Four modes (Clean, White+, Gum Health, Deep Clean+) and three intensities give 12 settings in total.
• Ships with a charging stand and a USB charging travel case, plus a brush head replacement reminder.

Good to know

• Only one C3 Premium Plaque Control head is included, so budget for spare heads soon after buying.
• There is no handle display; app pairing is needed for guided brushing and progress tips.
