Why this made the list
Cordless pool robots solve a real annoyance with corded ones: no cable to manage, no outlet you need nearby, no cord to get tangled or work its way into the intake. The Seagull Pro is Aiper's flagship cordless cleaner, and it's cheaper than the wall-climbing Dolphin Nautilus CC Plus while still climbing walls itself, which isn't a given in the cordless category.
What it actually does
It runs on a 9000mAh onboard battery rather than a power cord, rated for roughly three hours of total runtime split across floor and wall cleaning, and recharges in about 90 minutes on a large external charging brick. It climbs walls using top-mounted water jets that hold it against the surface as it crawls, a genuinely uncommon feature for a battery-powered pool robot. It's rated for pools up to 3,200 square feet and depths to 10 feet. Independent reviewers who've tested it describe strong cleaning performance, calling out dual rotating brush belts that handle both floor debris and algae on walls effectively.
Who this is actually for
Someone who wants wall-climbing coverage without dealing with a power cord, and who's willing to accept a shorter per-charge runtime in exchange for that cordless convenience. It's also the better fit for anyone whose pool layout makes running a cord to an outlet awkward.
What to weigh before buying
- Three hours of runtime is finite. On a larger or more complex pool, you may not get a full floor-plus-wall clean in a single charge, and you're waiting roughly 90 minutes to recharge before running it again.
- Reviewers report it can get stuck on obstacles like in-floor cleaning nozzles, worth checking your pool's fittings against this before buying.
- Cleaning the filter basket after a run is reportedly a bit messy, debris tends to cling to the mesh rather than dumping out cleanly.
- It's still a genuinely expensive pool robot, cheaper than the corded Dolphin CC Plus, but this isn't a budget category overall.
The verdict
A strong cordless option with real wall-climbing ability and reportedly excellent cleaning performance, held back a bit by limited runtime and some reported quirks with obstacles and filter cleanup. Worth it if going cordless matters more to you than maximum runtime per charge.
