BISSELL® SpinWave® Hard Floor Expert wet and dry robotic vacuum gives you two ways to clean in one revolutionary robot. Its two-tank system powerfully vacuums or actively mops. So, when used in dry vacuuming mode it collects pet hair, dirt, and other debris across multiple surfaces, and when used in wet mopping mode, the mop pads and BISSELL cleaning solution scrub messes on sealed hard floors for you. And, thanks to the Soft Surface Avoidance Sensor, you don't have to worry about it cleaning surfaces like rugs 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.
