A simple, light cordless robot for small above-ground and flat in-ground pools that cleaned in tidy lanes and reached corners in Popular Science testing. It is rated for only 1,150 sq ft, no reviewer measured its runtime, and WinFuture says the waterline still needs a hand. Pick it as a cheap first robot for a small pool; skip it for a big or sloped pool.
Best for: small above-ground pools. Skip if: your pool is over 1,150 sq ft.
