Pet lovers rejoice. The Neato XV-21 Automatic Vacuum Cleaner is specially designed for pet owners and allergy sufferers. With the most powerful suction of any robot vacuum, the XV-21 picks up dirt, debris, and even the toughest pet hair. The Neato XV-21's special filter retains more than three times the amount of fine dust particles as standard filters, which is perfect for removing allergens from the home. A new combination bristle and blade brush improves the pick-up of pet hair, dander and fibers. The vacuum works great on all types of floor surfaces including carpet, hardwood, Pergo, linoleum, vinyl, and tile. Before it cleans, Neato maps its surroundings to avoid bumping into furniture and walls.
