Quick verdict
The best surface skimmer we've researched: a huge basket, solar all-day running, and smart navigation. Buy it as a complement to a floor cleaner, not instead of one.
Ideal for
- Pools with heavy floating debris (leaves, pollen)
- Owners who already have a floor robot
- Buyers who want the top skimmer with app control
Not ideal for
- Anyone expecting floor or wall cleaning
- Owners who only want one robot (get a floor cleaner)
- Tight budgets
The full picture
The iSkim Ultra is Beatbot's dedicated surface skimmer — not a floor cleaner. It patrols the water surface collecting leaves, bugs, and pollen into a large 9-liter basket, runs on a 10,000 mAh battery topped up by a 24W solar panel for continuous daytime operation, and uses seven motors and twenty sensors for navigation and edge coverage, all controllable from the app. For a pool that fights floating debris and where you want the top-tier skimmer, this is the reference model. It complements a floor robot; it doesn't replace one.

The in-depth review
The iSkim Ultra is the best surface skimmer we've researched — a huge 9-liter basket, solar-assisted all-day running, and smart multi-sensor navigation. Buy it to complement a floor cleaner, not to replace one.
The best skimmer, with a caveat
Its 9-liter basket goes days between empties, solar power keeps it working all day, and app control plus multi-sensor navigation let it cover the surface intelligently. A skimmer's value is timing: it grabs leaves and pollen while they're still floating, before they waterlog, sink, and stain — so your floor robot and filter have far less to deal with.
What it isn't
It's surface-only — no floor, wall, or waterline cleaning — it's premium-priced for a complement device, and solar output drops on overcast days.
