Ecovacs Deebot T90S Pro drops to $699 at Amazon

The Deebot T90S Pro is designed to clean hard floors with an OZMO ROLLER 3.0 system. Ecovacs says 32-way pressurized water flow rinses the roller during cleaning, while a scraper removes dirty water to help limit smearing and the spread of grime.

For vacuuming, the unit offers up to 40,000Pa of suction and anti-tangle brushes intended to reduce hair wrap. Its OMNI Station automatically removes dust, washes the roller with hot water, dries it with hot air and dispenses cleaning solution. The deal is available at Amazon.
