Designed for in-ground pools up to 20 by 50 feet, this easy-to-use pool-cleaning robot offers a hands-free way to clean at just the touch of a button. It systematically covers the entire pool in about three hours, vacuum cleaning from floor to waterline and everywhere in between. Sturdy PVA roller brushes "power scrub" all pool surfaces including vinyl, fiberglass, and tile. The unit cleans over 70 gallons of water per minute, and its filtration system picks up leaves, hair, dirt, dust, algae, and particles as small as two microns, reducing the run time of the pool's primary filtration system. The machine also circulates pool water, improving the distribution of chemicals and water temperatures. Best of all, there's no need for bulky hoses, booster pumps, suction lines, or installation. Simply plug the robot in, drop it in the pool, and let it go. Other highlights include an auto-reverse function to prevent hang-ups, a 60-foot floating power cord with a swivel cord detangler, and a durable ultra-lightweight design. The pool-cleaning robot measures 19 by 15-2/3 by 14-3/5 inches and carries a one-year warranty.
