Read the review →Buying a robotic pool cleaner shouldn't take a weekend of research. The whole decision comes down to a handful of questions about your pool, and once you answer them, the shortlist gets very short. Use the finder below, then read on for what each answer actually changes.
The four questions that decide it
Almost every robot recommendation turns on four things: your pool's surface, its size, its worst debris, and whether you'd rather manage a cord or a battery. Answer those and you've eliminated most of the market. Everything else — apps, mapping, self-emptying — is refinement on top of getting those four right. The finder walks you through them and points you at the models that fit.
Pool size and cord vs cordless
Size and power source are linked. A large pool that takes a long time to clean favors a corded robot, because a cordless model's battery can run down before the job's finished — a corded Dolphin or Polaris never quits mid-cycle. A smaller pool, or one where fishing a cable out from around the ladder genuinely annoys you, is where cordless earns its premium: models like the Aiper Scuba S1 and Beatbot AquaSense 2 clean just as well and drop the cord. Freeform shapes lean cordless too, since cables snag on curves.
Surface and coverage
Your pool's surface and how much of it you need cleaned narrow things further. Most robots handle vinyl, fiberglass, and gunite, but check the rating for a delicate liner. More important is coverage: floor-only, floor-and-walls, or floor-walls-and-waterline. On an in-ground pool with a visible scum line, waterline cleaning is worth insisting on; on a soft-walled above-ground pool, a floor-only model like the Dolphin E10 is exactly right and cheaper.
Debris type
Your worst debris picks the details. Heavy leaves call for a big basket or a swappable bag like the Dolphin Premier's; fine dust and silt call for fine filtration like the Dolphin Quantum's; floating leaves and pollen are a job for a surface skimmer alongside a floor robot, not the floor robot alone. Match the machine to the mess and you won't be disappointed. Answer the finder's questions, take its shortlist, and confirm the exact specs on the model's page before you buy.
Frequently asked questions
How does the Pool Robot Finder choose a cleaner?
It should match your pool type, size, surface, main debris problem, wall and waterline needs, cord preference, cleaning frequency, and budget to cleaner categories instead of pushing one random model.
What is the most important pool robot feature?
The most important feature is fit. A cleaner must match your pool size, pool surface, debris type, and cleaning expectations before app control or fancy extras matter.
Do I need a wall-climbing pool robot?
You need wall climbing if your walls get visible dirt, algae film, or waterline buildup. If your pool floor is the only problem, a floor-focused robot may be enough.
Should I choose corded or cordless?
Choose corded for larger pools and longer repeat cleaning. Choose cordless if cable handling would stop you from using the robot regularly.
What should I check before buying a pool robot?
Check pool-size rating, cleaning coverage, filter type, cord or battery details, weight, warranty, return policy, and whether replacement filters and brushes are easy to buy.
