Yes, Roomba really works! Roomba uses a unique and powerful patented 3-stage cleaning system to sweep and vacuum most home floor surfaces, including hardwood, laminate, linoleum, low-pile carpet, medium-pile carpet, tile, slate and other hard surfaces.
Independent testing proves that Roomba works as well as or better than standard upright vacuums on hard floor surfaces and low to medium-pile carpet when used for routine cleaning. What’s more, Roomba’s compact shape allows it to reach under beds and other furniture, so it actually cleans more of your floor than a standard upright can. If your bed or furniture clears the floor by at least 3.5 inches (approx. 90 mm), Roomba will happily clean underneath.
