Aiper
Aiper Seagull SE
Model: Seagull SE
The cheapest pool robot genuinely worth owning. It is light, cordless, runs around 90 minutes, and cleans the floor of an above-ground pool up to about 40 feet. Do not expect wall climbing or waterline scrubbing at this price. For a flat-bottom above-ground pool it is all you need, and it is the least you can spend without dropping into no-name territory. Important: it is a different, non-recalled product from the Aiper Seagull Pro that was recalled for fire risk, but always check your exact model against the active CPSC notices before charging.
Aiper
Aiper Scuba S1
Model: Scuba S1
If you have an inground pool and want cordless on a budget, the Scuba S1 adds wall and waterline cleaning and a longer battery (up to 180 minutes) that the Seagull SE lacks. Two honest caveats. First, reviews are mixed: pool-specialist The Pool Nerd was lukewarm on its value, so read that before buying. Second, it is an Aiper cordless, and Aiper has a fire-recall history on other models (Elite Pro, Seagull Pro), so confirm your exact unit is not on the CPSC list. It is a real step up from the Seagull SE for inground pools, but buy it on sale and buy it clear-eyed.
Maytronics
Dolphin Nautilus CC
Model: Nautilus CC
If the cordless fire recalls make you nervous, this is the answer: a corded robot has no large lithium battery to overheat, so the whole hazard category goes away. The Nautilus CC is Maytronics' entry corded cleaner, with a top-loading filter, active scrubbing brush, and the most mature parts-and-service network in the category. It costs more than the Aipers and you deal with a cord, but it is the most defensible buy on this list for anyone who wants cheap-ish and worry-free over rock-bottom price. Certified open-box units turn up under $500.
How we picked
This guide is a synthesis. We have not personally tested every budget pool robot. We leaned on the 2026 testing at The Pool Nerd and The Gadgeteer plus the primary CPSC recall notices, and we reused the verified product identities from our main pool cleaner guide and above-ground guide. Where we cite a price, a runtime, or a recall, the source is at the bottom.
At the budget end we weighted two things above features: does it match your pool (above-ground vs inground) and is it safe (the cordless fire recalls are real and specific). A cheap robot that fits your pool and is not on a recall list beats a feature-packed one that is wrong on either count.
The one thing to check before you buy any cheap cordless
Budget pool cleaning has a safety problem that the vacuum and mower categories do not: cordless models carry large lithium batteries, and several cheap ones have been recalled for catching fire. The CPSC has recalled the Aiper Elite Pro and Aiper Seagull Pro, and the Wybot S1 and Wybot Osprey 700 Max, all for batteries that can overheat and burn.
So before you spend a dollar: check your exact model and model number against the active notices at CPSC.gov, and only ever charge with the adapter that came in the box. This is not a reason to avoid cordless entirely, the picks below are not on the recall lists, but it is the reason a corded robot is the genuinely safe budget choice if the risk bothers you.
Why the Aiper Seagull SE is the budget pick
For a small, flat, above-ground pool, the Seagull SE is all the robot you need and the least you can responsibly spend. Under $160, cordless, light enough to lift out with one hand, and it cleans the floor without you dragging a hose around. It will not climb walls or scrub the waterline, and the runtime is short, but none of that matters for a flat above-ground pool. It is a different product from the recalled Seagull Pro; verify your unit anyway.
When to step up to the Scuba S1 or a corded Dolphin
If you have an inground pool, the Seagull SE is not enough, and you have two honest budget paths. The Aiper Scuba S1 stays cordless and adds wall and waterline cleaning plus a much longer battery, but its reviews are mixed and it carries the general Aiper cordless caveat, so buy it on sale and check the recall list. The Dolphin Nautilus CC goes corded, which removes the battery-fire risk entirely and brings Maytronics’ reliability and service network, for more money and the minor hassle of a cord. If you want cheap and worry-free, the corded Dolphin is the pick; if you want cheap and cordless for inground, the Scuba S1 is the option, eyes open.
Who should buy at this price
Anyone with a small above-ground pool should just buy the Seagull SE and move on. Inground-pool owners on a budget should decide which they value more, the convenience of cordless (Scuba S1, on sale, model verified) or the safety and longevity of corded (Dolphin Nautilus CC). What nobody should do is buy the cheapest no-name cordless on a marketplace without checking whether that exact model has been recalled.
