Robot vacuum machine
Roomba sweeps and vacuums just about any home floor surface, including; hardwood, laminate, linoleum, low-pile carpet, medium-pile carpet, tile, slate, and other hard surfaces. Roomba's compact shape enables it to clean completely under beds, tables and other furniture, so Roomba can clean more, in more places than conventional vacuums. In fact. Roomba cleans better than uprights costing twice as much.
