NEATO XV-21 Pet and Allergy 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. It scans, maps and plans. Most other robot vacuums move around a room at random. They bump into walls, bump into furniture. They go in circles, cleaning some spots several times and others not at all. But NEATO knows exactly where it?s going at all times. Its remarkable laser eye uses infrared light to scan the surroundings five times every second. The result is a highly accurate 360? map of the room and any obstacles. Then the robot efficiently cleans in a pattern of straight, overlapping lines. Don?t you dare call it a sweeper. A lot of robot ?vacuums? are really just sweepers. Their low vacuum power is merely an add-on, but not the NEATO. It?s the most powerful robot vacuum available today. At the core of every NEATO is a centrifugal compression-impeller that uses jet engine airflow principles to create high-powered suction. You can count on it to pick up everything a traditional vacuum would dirt, pet hair, dust, cereal and more.
