Pool-cleaning robots have quietly turned into small appliances with their own personalities, and the gap between the cheapest and priciest in this group is wide. Ten models sit here, stretching up to. That spread alone tells you how differently these machines are built and who each one is really.
Buying a robotic pool cleaner is less about brand loyalty and more about fit: pool size, the kind of debris you battle, and how much you want the machine to think for itself. The 10 cleaners in this guide range, which covers everything from a lightweight cordless unit for a small above-ground pool to a Wi-Fi-scheduled flagship built for in-ground pools up to 50 feet. Some lean on raw suction, others on smart navigation, and a couple split the difference. To rank them, we pulled current specs, images and Runtime, suction figures, filtration, coverage area and navigation all factored in, alongside how cleanly a model fits a common buyer need. The result is a list where the higher a cleaner sits, the better it scored for the money, not just on paper.

Things to consider
8 Things to Consider Before Buying Dolphin Pool Cleaner
Before you compare suction numbers, start with your pool: its size, surface mix, and whether it is in-ground or above-ground. The factors below map the specs buyers actually weigh for these robots, from coverage area and runtime to filtration and navigation, so you can match a machine to your space instead of overpaying for features you will never use.
Coverage area vs. your pool size
These cleaners list very different maximum coverage. The Beatbot Sora 30 and Sora 10 each cover up to 3,229 sq ft, the Ecovacs Ultramarine P1 reaches 1,937 sq ft, the Wybot C1 handles up to 1,615 sq ft, and the Robokleen tops out at 1,100 sq ft. Buy more coverage than your pool needs and you waste money; buy less and a single session may not finish the job.
Runtime on a single charge
Cordless robots live and die by battery life. The Beatbot Sora 30 and Sora 10 quote up to 300 minutes, the Aiper Scuba S1 lists 180 minutes, the Ecovacs P1 also runs up to 180, the Wybot C1 reaches 152 minutes, and the 2026 Aiper Scuba S1 stretches to 240-270 minutes in Eco Mode. Longer runtime matters most for large pools or heavy debris that needs more passes.
Suction power for heavy debris
Suction is rated in GPH here, and the range is dramatic. Both Beatbot Sora models advertise 6,800 GPH, the Ecovacs P1 claims 4,800 GPH with anti-clog tech, the Wybot C1 lists 3,038 GPH, and the Robokleen puts out 2,700 GPH from dual 50W motors. If your pool collects leaves and grit, lean toward the higher figures.
Filtration fineness
A dual-layer filter catches both leaves and the fine stuff that clouds water. The Aiper Scuba S1, Ecovacs P1, Aiper Scuba V3 and 2026 Aiper Scuba S1 all pair a 3-micron ultra-fine filter with a 180-micron standard filter. The Robokleen uses a single 180-micron mesh. Finer filtration helps most with sand, pollen and algae particles.
Surface zones it actually cleans
Not every robot scales walls or scrubs the waterline. The Aiper Scuba S1 and Beatbot Sora 30 clean floor, walls, waterline and shallow areas, while the Dolphin Nautilus CC Supreme adds an active waterline scrubbing brush. The Dolphin Nautilus AG focuses on above-ground pools with its scrubber and smart navigation. Match the zones to where your dirt actually collects.
Smart navigation and app control
Navigation determines whether the robot maps your pool or wanders. The Aiper Scuba S1 uses 11 high-precision sensors with dual-path algorithms, the Ecovacs P1 runs IMU-powered SmartNavi for up to 99% floor coverage, and the Aiper Scuba V3 adds a front-facing AI camera that detects over 20 debris types. App support on the Aiper, Wybot, Ecovacs and Aiper V3 lets you schedule and track cleanings remotely.
In-ground vs. above-ground fit
Some models are pool-type specific. The Dolphin Nautilus CC Supreme is built for in-ground pools up to 50 feet, while the Dolphin Nautilus AG targets above-ground pools up to 33 feet in length. The Wybot C1, Ecovacs P1, Beatbot Sora 10 and Robokleen list both in-ground and above-ground compatibility. Confirm the fit before buying so the robot can climb and clean your specific pool.
Weight and handling
You lift these in and out by hand, so weight counts. The Robokleen is the lightest at 8.6 lb, the Dolphin Nautilus AG lists 14.55 lb, the Aiper Scuba S1 comes in at about 16.98 lb, and the Dolphin Nautilus CC Supreme is the heaviest at 24.6 lb. If you will retrieve the robot daily, lighter is friendlier on your back.
Verdict
Our Final Verdict
After comparing all 10, the Aiper Scuba S1 Robotic Pool Cleaner takes the top spot for balancing four-zone cleaning, dual-layer filtration and an 11-sensor navigation system at a mid-range The Robokleen Cordless Robotic Pool Cleaner is the value play, the lightest unit here at 8.6 lb with dual 50W motors and an 8L basket. If budget is no object, the Dolphin Nautilus CC Supreme Wi-Fi Automatic Robotic Pool Vacuum Cleaner is the premium choice, with always-connected Wi-Fi scheduling and an active waterline scrubbing brush for in-ground pools up to 50 feet. It is also the heaviest at 24.6 lb and by far the most expensive, so only pay up if those features earn their keep in your pool.
