"Reach" is the manufacturer's rated floor area per charge for cordless robots and the longest pool a corded robot is rated for. Cordless and corded figures aren't directly comparable — see corded vs cordless and how coverage ratings work.

Specs are manufacturer ratings from Amazon listings and spec sheets. Prices are typical US street prices as of October 2026 and change often.

FAQ

Which robotic pool cleaner has the best specs in 2026?
By our research-based score, the Beatbot AquaSense 2 currently ranks highest (8.7/10), but the best robot for you depends on pool type, size, debris and budget. Sort the table by the spec that matters most, or use the robot matcher.
What is the difference between a corded and a cordless pool robot?
Corded robots (like the Dolphin Nautilus line) plug into a poolside power supply and run as long as you want, with strong suction and a proven record. Cordless robots (Beatbot, Aiper, Wybot) run on a rechargeable battery for roughly 1.5–5 hours, with no cord to manage and newer models that also clean the waterline.
Do I need a skimmer robot or a vacuum robot?
A vacuum robot cleans the floor and (usually) the walls. A solar skimmer only handles the surface: leaves, pollen, bugs. If trees drop debris on your pool, many owners run both. If you only get a little surface debris, a vacuum robot alone is usually enough.
