Corded waterline robots

Corded robots that climb all the way to the tile and scrub along it. This is where the pool-trade brands concentrate their range: long default cycles, app scheduling, and swivels to stop the cable coiling.

11 robots · 3 brands, $999–$2,999

Ordered by the pool length each robot’s cable or battery covers, longest first, then by price; robots with nothing published to check come last.
