Claims against testing

Smart-mapping vs random-path pool cleaners: when does mapping return on investment?

Smart mapping is sold at a higher price than a plain scanning path. This page sets what each maker says about its navigation beside what testers found on the pool floor.

Under the water at the deep end of a pool, three pool robots climb a dust-covered slope toward the shallow end, each leaving its own clean lane: a smooth wave, a hairpin back down beside itself, and one straight run, the two corded robots trailing cables up to the surface.

Mapping, claimed and tested

What each navigation claim comes with

Aiper product page

Same on all three: each cleans floor, walls and waterline and each has a phone app.

Seen from the side deck, a pool robot has turned back at the foot of a pool's entry steps, its clean lane looping round at the bottom riser while dust still lies on every tread, its blue cable floating to the far wall and over the coping to its power supply.

  • Dolphin Nautilus CC Supreme · Maytronics US store page (2 Oct 2026); PCWorld review (18 May 2026); Robotic Reviews owner summary
  • Alpha iQ+ · Dealer pages (Simplified Pools, Bay State Pools) carrying Polaris copy, read 2 Oct 2026
  • Scuba S1 Pro · Aiper US product page (2 Oct 2026); Test Your Own Pool review of the S1 and N1 checked and not used

Each claim is quoted from a page opened on 2 Oct 2026. Where only a dealer page carrying the maker's copy could be read, the cell says so. Reviews of a sibling model were not used.

Questions

What readers ask

Does mapping clean a pool in less time?

No test found compared a mapped path with a plain one on these three. Each maker states its own cycle length, and the figures cover different modes, so they cannot be lined up.

Does any of these store a map?

Not confirmed. The Aiper page names intelligent mapping but not a stored map. The other two pages read did not name a stored map.

Why is the Polaris cell marked as dealer copy?

The maker page for the Alpha iQ+ returned no readable content, so the navigation, cycle and cable figures come from dealer listings that reproduce Polaris wording.
