BISSELL SpinWave wet and dry robotic vacuum provides two ways to clean in a single revolutionary robot. The two tank system actively mops or powerfully vacuums with smart, structured cleaning paths. Use it in dry vacuuming mode to collect pet hair, dirt and other debris on carpet, area rugs and hard floors. When used in wet mopping mode, the mop pads and BISSELL cleaning solution work together to scrub floors clean. And, with the Soft Surface Avoidance Sensor, there's no need to worry about the robot going up on area rugs or carpets when in wet mopping mode. Plus, this product doesn't just clean up after pets, it helps save them, too. BISSELL proudly supports BISSELL Pet Foundation and its mission to help save homeless pets. When you buy a BISSELL product, you help save pets, too. We're proud to design products that help make pet messes, odors and pet homelessness disappear.
