Robotic pool cleaners · updated 2026-09-29

The pool size on the box is a claim. The cable length and the battery runtime are how you check it.

A corded robot reaches as far as its cable, less the depth of the deep end. A cordless one covers as much floor and wall as its battery lasts. Every robot here gets that arithmetic done, beside the finest filter in its box and what it takes to lift it out of the water.

Every robot in the catalog

Filter by brand, type, power, price and the length of your own pool. The default order is the pool length each robot’s cable or battery actually covers, longest first; robots whose makers publish nothing to check that against come after. Tick up to three and their specifications line up in one table.

Shortlists, each stating what it ranked on

Cordless Robots With the Battery for a 16 × 32 In-Ground Pool

23 qualifying robots

Cordless wall-climbers the maker rates for in-ground pools, whose published runtime covers at least a 32 ft pool at 13 sq ft a minute; ordered by the pool length that runtime supports (floor-only figures after floor-and-wall ones), then by price.

Robots Rated for Above-Ground Pools

26 qualifying robots

Every floor robot whose maker lists above-ground pools, ordered by price. Skimmers are left out; they have their own guide.

Corded Robots That Scrub the Waterline for Under $1,500

7 qualifying robots

Corded robots whose maker lists waterline scrubbing, priced under $1,500, ordered by price.

Robots That Filter Fine Dust and Algae (50 Microns or Finer)

5 qualifying robots

Every robot whose in-box filter the maker rates at 50 µm or finer, ordered by that rating and then by price. Optional filters sold separately do not count.
