CleanMate is your personal robot that will sweep and vacuum so you don't have to. From carpet to hardwood to tile CleanMate handles a variety of surfaces with ease. It goes under beds and other places where upright vacuums can't go to clean dirt dust and pet hair while simultaneously killing bacteria and deodorizing with its ultraviolet light. CleanMate works for about 60 minutes on a single charge. CleanMate is even smart enough that it won't fall down steps or elevated surfaces. CleanMate comes with an easy to use remote that fits right on the unit when you're not using it so it doesn't get lost.
