A clean pool is mostly invisible work. You only notice it when leaves drift to the bottom or the waterline turns grimy, and by then the skimming you skipped has become a chore. The ten robots in this guide, which is a wide enough gap that the right pick depends far more on your pool than on your wallet.
Robotic pool cleaners split into two jobs that get lumped together: skimmers that work the surface and vacuums that scrub the floor, walls, and waterline. This guide covers both, because the label on the box matters less than whether the machine reaches the debris your pool actually collects. A floating skimmer like the Betta SE Plus catches leaves and pollen before they sink; a floor vacuum like the Ecovacs Ultramarine P1 goes after what already has. We pulled current Amazon Solar charging, battery runtime, filtration micron ratings, and app control were the specs that separated the field. The higher a model sits, the better it balanced those traits against its
The short version: The Betta SE Plus is our top pick, a solar-powered surface skimmer with twin Salt Chlorine Tolerant motors and a shallow water safeguard that earned the highest score of the ten cleaners here.

Things to consider
8 Things to Consider Before Buying Pool Cleaner
Before you compare runtimes and suction numbers, decide what surface you most need cleaned, because a skimmer and a floor vacuum solve opposite problems. From there the specs that matter cluster tightly: pool size coverage, debris handling and filtration, runtime per charge, and how the robot navigates. Use the factors below to match a model to your pool rather than chasing the longest feature list.
Skimmer or floor vacuum
The biggest fork is what the robot cleans. Surface skimmers like the Betta SE Plus and the Aiper EcoSurfer S2 float and pull in leaves and pollen before they settle, while floor vacuums like the Ecovacs Ultramarine P1 and Beatbot Sora 10 climb the floor, walls, and waterline. If debris sinks fast in your pool, a vacuum earns its keep; if leaves blow in constantly, a skimmer keeps the surface clear.
Pool size and coverage
Several listings state the area they are built for, so match that to your pool. The Beatbot Sora 10 claims coverage up to 3,229 sq ft, the Ecovacs Ultramarine P1 up to 1,937 sq ft, and the Coasteering Planet Edge up to 850 sq ft for flat pools. The Dolphin Nautilus AG is rated for above-ground pools up to 33 ft in length. Buying past your pool's size wastes money; buying under it leaves spots uncleaned.
Battery runtime per charge
Cordless models live or die on runtime. The Beatbot Sora 10 leads here at up to 300 minutes from a 7,800mAh battery, with the iGarden KN Series at 210 minutes and both Ecovacs and the original Aiper Scuba S1 at 180 minutes. The Coasteering Planet Edge runs up to 120 minutes but recharges in about 2.5 hours. Longer runtime means fewer interruptions on bigger pools.
Filtration and debris capture
Micron ratings tell you how fine the catch is. The Aiper Scuba S1 and Ecovacs Ultramarine P1 both pair a 3-micron ultra-fine filter with a coarser standard filter, while the Betta SE Plus uses a 200-um fine-mesh basket and the Aiper EcoSurfer S2 a 150-micron filter. The Beatbot Sora 10 takes a different tack with a 5L basket rated to hold up to 650 leaves, cutting how often you empty it.
Navigation and obstacle handling
Smarter pathing means fewer missed patches and less aimless wandering. The Aiper Scuba S1 uses 11 high-precision sensors with dual-path algorithms, the Ecovacs Ultramarine P1 runs IMU-powered SmartNavi claiming up to 99% floor coverage, and the iGarden KN Series adds Smart 3D Navigation. The Betta SE Plus leans on ultrasonic radar for obstacle detection, and the EcoSurfer S2 pairs dual sensors with anti-stranding columns to avoid steps.
Charging style and power source
Two of these robots charge from the sun. The Betta SE Plus runs 24/7 on solar with 5 to 6 hours of charge under direct sunlight, or 3.5 hours via adapter, and the Aiper EcoSurfer S2 offers the same dual-charging approach. The rest are battery-and-adapter cordless designs. Solar suits owners who want set-and-forget surface cleaning without plugging in.
App control and scheduling
App support turns a cleaner into something you can run remotely. The Aiper Scuba S1, Ecovacs Ultramarine P1, Aiper EcoSurfer S2, and the 2026 Aiper Scuba upgrades all offer app control, and several add OTA updates or custom schedules. The iGarden KN Series instead uses on-unit LED mode indicators. If you want to start a cycle from your phone or set a weekly plan, check for app support specifically.
Surface and waterline coverage
Not every vacuum reaches the walls. The Aiper Scuba S1, iGarden KN Series, Ecovacs Ultramarine P1, and Beatbot Sora 10 all list floor, wall, and waterline cleaning, with several handling shallow areas down to 12 inches. The Coasteering Planet Edge focuses on the floor of flat pools. If your waterline tends to ring, prioritize a model that explicitly scrubs above the floor.
Verdict
Our Final Verdict
The Betta SE Plus takes the top spot for its solar 24/7 skimming, twin Salt Chlorine Tolerant motors, and shallow water safeguard, which together scored higher than anything else here. If price is the priority, the Coasteering Planet Edge Pool Vacuum is the clear value play, a cordless floor cleaner for flat pools up to 850 sq ft at well under half the cost of the premium picks. For the most features, the Aiper Scuba S1 Robotic Pool Cleaner brings 11-sensor navigation, dual filtration down to 3 microns, and app control for full floor, wall, and waterline coverage. Note that three different cleaners share that ceiling, so spend it only if the spec sheet matches your pool.
