The appliance can vacuum and wet-clean up to 150 square metres at a time. A capacious 350 ml water tank and electronic water supply control with three modes (Low, medium, high) allow you to choose the best cleaning scenario depending on the type of flooring and level of dirt This remote sensing technology uses a laser to collect spatial measurements, which can then be utilized to create 3D models and maps of objects and rooms. Smart room mapping allows the device to memorize all the objects in the room and bypass obstacles, making cleaning more efficient When the battery is low, the cleaning is paused for charging and then resumed from the same spot.
