The most complete cordless cleaner here: it handles the floor, walls, waterline and the water surface in one robot, and independent reviewers found it cleaned very well. It is heavy at about 29 lb, loses its app connection underwater, and still costs close to two thousand dollars on sale. Skip it if you have a small pool or would rather pay less for a corded robot on a weekly timer.

- 50 ft long
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.

What reviewers found
Beatbot AquaSense 2 Ultra
- Reviewed: Did an excellent job on bottom and sides and left clear water, but could not clean the shallow tanning area or Baja shelf, lost Wi-Fi underwater, and its near 30 lb weight was hard to haul. Source
- Android Authority: Editor's Choice; pulled more debris, including small rocks, from an already clean pool than other robots tested. Downsides were bulk, price, and one failed charge due to wet contacts. Source
- The Pool Nerd: Named best cordless pick in its 2026 roundup but still labeled it Pool Nerd Disapproved, citing mesh filtration at flagship price and the daily charge and haul routine. The site prefers corded robots and earns affiliate commissions. Source
Dolphin (Maytronics) Premier
- Bob Vila (9/10): Cleaned light leaf litter, tile line algae and storm dirt in a Miami pool, ran quietly at about 5 cents per hour, but was heavy to lift and the caddy and remote cost extra. Source
- The Pool Nerd: Names it the author's personal favorite after testing about 30 robots, citing suction, filter choices and the 3 year warranty. Affiliate site with links to Dolphin dealers. Source
