Keeping hard floors clean requires both sweeping and mopping. Eufy's S1 Pro is designed to handle both. Its 290mm roller mop uses rotational speed and downward pressure to mimic human scrubbing, with one tank for water mixed with cleaning solution, and a second for wastewater squeezed out of the roller mop. 3D MatrixEye Obstacle Avoidance combines binocular infrared sensors and an RGB camera to identify toys, cables, shoes, pet messes, and more, safely navigating around them. 8,000 Pa suction power removes deep-seated dust and debris from hard floors and carpets, and when cleaning is done, it returns to its sleek 10-in-1 Uniclean Station which charges the battery, automatically empties the dustbin, refills the clean water tank, cleans and dries the mopping pads, and removes the wastewater, leaving the S1 Pro ready for its next duty.
