All pools need chemicals to stay clean, but the fewer chemicals your pool needs, the healthier it is for you and your family. Aquabot robotic pool cleaners provide crystal clear water, fewer chemicals and a healthier clean. Aquabot cleaners remove more dirt and debris, from both surfaces and the water, to keep your pool physically cleaner so it needs fewer chemicals. Aquabot cleaners also offer the strongest pumps in the industry. Aquabots do a better job of mixing the chemicals that tend to settle in deep water with chemically-depleted top water substantially reducing the need for chemicals. The Breeze 4WD cleaner is for use in in ground pools up to 60". It can be used on any pool surface type and is ideal for gunite pool surfaces. The Breeze cleaner has an active scrubber with rotating brushes that loosens up dirt and debris for a deeper clean. It features two large debris baskets that are accessible from the top and have a clear cover to make them easy to view. They can capture an extraordinary amount of debris and make for easy emptying and cleaning. The 4WD has excellent traction and can climb mid-wall and inclines. It is propelled by a 4WD, two way motor with auto turning that provides excellent coverage. The cleaner can cover 450 square feet per hour. It filters 70.4 gallons of water per minute. It uses a nylon mesh filter that filters down to two microns. The cleaning programs are approximately one hour for small pools and two hours for larger pools (question 3 hours). The extreme suction and filtration capabilities ensure a super-fast cleaning. The cleaner includes a 60" self-floating cable.
