- 40 ft long
The cheapest way here to get a corded robot on a weekly timer, which means no daily charging or hauling. It is light and simple, but Maytronics does not list waterline scrubbing, there is no app, and it is rated for pools up to 40 ft. Skip it for large or very leafy pools.

A proven corded cleaner for in-ground pools that get leaves, with a weekly timer and filter options from a big leaf bag to fine cartridges. It has no app and weighs about 20 lb dry. Maytronics showed it as unavailable on its own store when checked, so expect to buy from a dealer.
