Amazon.com Product Description
With a simple touch of the "clean" button, this entry-level vacuuming robot picks up amazing amounts of dirt and debris, keeping the whole floor effortlessly clean. The powerful unit automatically adjusts to any floor surface including wood, tile, linoleum, and low- to medium-pile carpet, while its counter-rotating brushes reach deep into carpet fibers to lift dust, pet hair, cat litter, food crumbs, and more. After determining the room size, the vacuum's artificial intelligence adjusts the run time to ensure thorough cleaning of the entire floor surface. Because it cleans under furniture, along walls, and other hard-to-reach areas, it actually vacuums more of the floor than a standard upright can. A gentle-touch bumper system senses obstacles so the vacuum automatically slows its approach, gently touches the obstacle, then redirects to continue cleaning under or around the object. The vacuum also senses dirtier areas and spends more time cleaning them, plus it can be set to Spot mode for fast cleaning of messy spills. Even more, built-in infra-red cliff sensors make it possible for the cleaner to avoid stairs and other drop-offs, and invisible barriers can be set using the unit's virtual-wall system. To mark off-limit areas, simply place a virtual wall at a doorway or other opening and adjust the infrared beam setting to the distance of the opening. The unit automatically detects the beam and will not go past it. Two virtual walls, a power supply, a rechargeable battery, an extra filter, and a brush cleaning tool come included. The vacuuming robot measures approximately 13-1/5 by 13-1/5 by 3-1/5 inches and carries a one-year limited warranty.
