Wirecutter's budget sonic pick, with a two-minute timer and 30-second pacing, about 17 days per charge in Electric Teeth's test, and a two-year warranty. It has no pressure sensor, one intensity and a USB-only charger, and Amazon owners report units that stop holding a charge or quit within two years.

Common Philips Sonicare 1100 problems

  • No pressure sensor, one intensity

    Wirecutter says it lacks the 4100's pressure sensor and head-replacement light and has one intensity, similar to the 4100's lower setting. Electric Teeth adds that the motor feels less powerful than premium Sonicare models.

  • Stops holding a charge or dies

    Amazon's review summary says battery feedback is mixed, with some owners saying it won't hold a charge, and multiple customers report it stops working in less than two years.

  • USB-only charger and slow charging

    Wirecutter says the 1100's stand has had only a USB plug since October 2021 (Philips sends a wall adapter free on request). Electric Teeth says a full charge can take up to 24 hours, and Amazon owners are mixed on the USB charging.

What experts say

  • Wirecutter (NYT): The pick if you want a vibrating brush cheaper than the 4100: two-week battery and a pacing timer, but no pressure sensor or replacement-reminder light, and only one intensity.
  • Electric Teeth: 4.1/5 (2025-10-14): a good budget brush from a major brand that cleans well, but no pressure sensor, no wall adapter and a sealed battery that can't be repaired. It recommends the 4100 if you want a pressure sensor.

If that catch is a deal-breaker

Highly ranked electric toothbrushes whose biggest complaint is a different kind of problem.

#1 in electric toothbrushesOral-B iO Series 6 Rechargeable Electric Toothbrush

Wirecutter's pick if you want to upgrade from the Pro 1000: quieter, with a lighted pressure sensor and a display, and about 16 days per charge in Electric Teeth's test. It regularly costs about three times as much as the Pro 1000, and its iO-only heads cost more than double standard Oral-B heads.

Its catch: costs much more, with iO-only heads#2 in electric toothbrushesOral-B iO Series 9 Rechargeable Electric Toothbrush

CNN's favorite smart brush, with seven modes, a color screen and app coaching. It costs about $300, uses pricier iO-only heads, and testers disagree on how accurate its tracking is. Its battery is shorter than many cheaper brushes.

Its catch: very expensive#3 in electric toothbrushesOral-B Pro 1000 Rechargeable Electric Toothbrush

Wirecutter's long-running top pick, with cheap, widely available heads. It is louder than sonic brushes, and its pressure alert is easy to miss. Owners also report units that stop holding a charge.

Its catch: stops holding a charge or dies early
