The Aiper Cordless Robot Pool Cleaner picks up dirt, leaves, and even sand from pool floors up to 538 square feet. The best-selling cleaner has dual suction motors and two brushes to efficiently clean your pool in just 50 minutes. One shopper said it has “surprisingly powerful suction,” and they “can’t believe how well it sucked up all the dead insects and leaves along with the dirt and grime.” If you’re not convinced that robot pool cleaners are a smart investment, Stewart Vernon, COO and founder of America’s Swimming Pool Company (ASP) told BH&G that, “robotic cleaners are pricier but are also the easiest pool cleaners to use. They use software to determine how to clean your pool.” The cordless pool cleaner catches sediment with its filter—and you can rinse the filter after a few uses to maximize its cleaning power. It weighs only 6.6 pounds, and it returns to a pool wall when the battery is running out to make it easy for you to reach in and grab it without jumping in the water. Just wipe the robot cleaner down with a towel and let it dry before charging. You can run the robot cleaner when the pool cover is on or while you’re swimming, however, Vernon suggests waiting until you’re out of the pool to ensure that debris has settled on the pool floor. It works on in-ground and above-ground pools, as long as your pool is flat on the bottom. One reviewer said it’s “such a huge timesaver,” while another shopper said, “Our in-ground pool sweeps never worked this good. I have seen this pool sweep pick up pebbles, larger rocks, Legos, grass clippings, dust, dirt, hair, [and] pretty much anything you can think of.” We independently research, test, review, and recommend the best products.
