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.

The base cordless Polaris cleans floor, walls and waterline in about 2.5 hours and parks for retrieval with Tap and Lift. The Pool Nerd ranks it as a saner cordless pick than no name robots, but notes suction fades as the battery drains. It costs a lot for a cordless robot without a remote.

Polaris FREEDOM
- The Pool Nerd: Named it the runner up cordless pick with longer runtime than many cordless units and wall climbing, but said suction and scrubbing fade as the battery drains and it does not match corded Dolphins. Source
