Market guide

Will it clean this pool

A pool-by-pool check for steps, ledges, slopes, drains, finish, depth, waterline, and the debris that actually arrives

Floor, wall, and waterline are useful labels but incomplete promises. A robot can clean an open wall and still miss a shallow ledge, lose grip on a slope, hang on a drain, or carry the wrong filter for the material that settles in the pool.

01

Draw the pool

Mark every transition before reading a feature list

Record length, shape, finish, deep end, slopes, beach entry, steps, benches, sun shelf, drains, corners, and the water depth over each raised area. Compare those measurements with the maker's stated operating limits.

Shallow areas
Beatbot states that steps need enough width and at least 1.31 feet of water for AquaSense 2 Ultra.
Floor fittings
Raised drains and covers can interrupt tracks or trap a cleaner that otherwise navigates the floor well.
Finish
Brush choice, traction, and possible scuffing differ across plaster, pebble, tile, vinyl, and fiberglass.
02

Separate the jobs

Surface, waterline, walls, and floor are different work

A robot that climbs the wall may not travel the waterline. A submerged cleaner does not necessarily skim leaves. Steps and ledges are a separate test even when the maker describes full-pool coverage.

Surface
Floating leaves and pollen may justify a surface-capable robot or a separate skimmer.
Waterline
Look for lateral travel and scrubbing at the surface, not only a wall climb.
Floor
Fine dust, sand, hair, and large leaves ask different things of the basket and filter.
03

Return-window test

Start with the hardest place and the worst debris

A clean rectangular section proves little. Run the robot after normal debris arrives, inspect the steps and corners, check whether it escapes the main drain, and weigh the retrieval routine while a return remains possible.

Coverage map
Photograph the missed material after a complete cycle instead of relying on app animation.
Filter check
Open the basket before rinsing and note which material passed through or clogged it.
Second cycle
Record charge, cooldown, or cable reset work when one cycle is insufficient.
