Top complaints

Oral-B iO Series 6 Rechargeable Electric Toothbrush

  • Costs much more, with iO-only heads

    Wirecutter says it regularly costs three times as much as the Pro 1000 and its heads cost more than double; standard Oral-B heads don't fit iO models. Electric Teeth lists the iO-specific heads and the non-essential Bluetooth as its cons.

  • Gunk builds up at the head mount

    Wirecutter notes some customer reviewers clean the junction between head and handle daily, and Electric Teeth says the attachment point can collect mold if not cleaned regularly.

  • Drooly brushing for some, slow charging

    The size and shape of iO heads gave some Wirecutter testers a more drooly experience than the Pro 1000. Electric Teeth says a full charge takes up to about 12 hours.

Oral-B Pro 1000 Rechargeable Electric Toothbrush

  • Stops holding a charge or dies early

    Amazon's review summary says the battery gets mixed feedback, with some owners saying it stops holding a charge and several saying it stopped working within two weeks. Walmart's lowest-rated reviews describe units that stopped charging after about two months, chargers that didn't work, and a motor that slowed down after a month.

  • Loud

    Wirecutter calls Oral-B brushes like the Pro 1000 louder and more sonically grating than comparable Sonicare models. Electric Teeth measured 73 dB, versus 60 dB for the Sonicare 4100. Amazon's summary says customers find it somewhat loud.

  • Weak pressure alert, no auto shut-off, vague battery light

    Wirecutter's testers had to press harder than expected to trigger the pressure sensor. The brush also keeps running after two minutes until you switch it off, and the battery light only shows full or low. Electric Teeth found the pressure alert neither visible nor audible and easy to miss.

  • Button and slippery handle

    Amazon's summary says some customers struggle with the on/off button. Walmart low-star reviewers say the button is hard to use and the smooth plastic body gets slippery when wet.
