Sonic vibration technology revolutionises robotic mopping. The mop now scrubs efficiently over the floor instead of just grazing it. The mop scrubs up to 3,000 times per minute. Connected to an electronic water tank, it cleans floors thoroughly and effectively. The intelligent mop lifts when the S7 detects a carpet, so you can mop hard floors and vacuum carpets. And it does it all in one go, without interruption. Plus, the mop raises when docked and when finished, so you can say goodbye to ugly plastic mats and dirty streaks. Using ultrasound, the S7 identifies carpets with exceptional accuracy. How you want it to clean your home is up to you. Whether the robot lifts the mop first and just vacuums, focuses on hard floors or simply mops, you decide what's best for your home. The improved main brush hugs the floor better to pick up dirt. The S7's new floating main brush has been improved to move in multiple planes for better cleaning on uneven surfaces. The old bristle design is gone and has been replaced with a ribbed solid rubber design. It is more durable. The spiral brush blades swirl better and the main brush can basically handle hair tangles better. A larger dust bin takes a lot of the work off your hands. The dust bin stores dust day after day. The water tank can deep clean up to 200 sqm in one pass. Power is supplied by a rechargeable battery.
