How to choose a robotic pool cleaner: a spec-by-spec buying guide

Buying guide, not a ranking
This guide explains which manufacturer-published specifications matter and why. It does not rank models, and RobotMatchup has not physically tested any product mentioned.
A robotic pool cleaner is rated by its maker for particular pools, surfaces and power setups, so the spec sheet answers most buying questions before price does. This guide walks through the manufacturer-published fields RobotMatchup records for every pool cleaner and what each one tells you. It is a buying checklist, not a ranking, and nothing here comes from hands-on testing.
1. Pool type and size
Start with the pool types the maker rates the unit for — in-ground, above-ground or both. Soft above-ground walls and flat floors are a different job from a plaster in-ground pool, and a unit outside its rated pool type is outside what the maker supports.
Then check the published maximum pool length and rated coverage against your pool. Where a maker publishes neither, the figure reads Not published rather than an assumed size.
2. Corded vs cordless
A cordless cleaner is limited by its published battery runtime and charge time; its cable length is N/A because there is no cable. A corded cleaner is limited by its published cable length and runs as long as it has power; its battery runtime and charge time are N/A unless the maker publishes a real value.
Neither design is automatically better. Cordless removes the floating cable and the outlet near the pool; corded removes recharging between cycles.
3. Floor, walls and waterline
Makers publish cleaning surfaces, wall climbing and waterline cleaning as separate claims. A floor-only model will not climb walls, a wall-climbing model is not automatically rated for the waterline, and a surface skimmer works the water surface only. Check each field you need rather than inferring one from another.
4. Filtration and suction figures
Some makers publish a flow rate or suction figure and a filter rating. These are useful for comparing models from the same maker, but brands measure differently, so treat small cross-brand differences as a tie. Where a figure is not published, RobotMatchup leaves it blank rather than estimating it.
5. App control and scheduling
App control and scheduling are separate published fields. A phone app does not by itself mean scheduled cleaning, and cleaning-mode names vary by maker. Check that the controls you want are actually stated for the model.
6. Budget and availability
RobotMatchup shows the manufacturer's list price, which can differ from a retailer's street price. Each model also carries an availability status, so you can tell a unit you can buy now from one that is announced or on preorder.
7. Dolphin and the cordless alternatives
Maytronics Dolphin has long been the default name in robotic pool cleaners. Cordless makers such as Beatbot, Aiper and Wybot now publish comparable cleaning-surface and coverage fields, so compare models on the sheet rather than on brand loyalty — and check that each figure you care about is actually published for both.
8. Compare popular models side by side
These pages put two cleaners from different brands in the same attribute grid, using only manufacturer-published values.
Frequently asked questions
- What is the most important spec on a robotic pool cleaner?
- Start with the pool types and size the maker rates the unit for, because a cleaner outside its rating is outside what the maker supports. Then decide on corded or cordless and check the cleaning-surface claims you need.
- Do I need a cleaner that climbs walls?
- Only if you want walls cleaned by the robot. Wall climbing and waterline cleaning are separate manufacturer claims, so check both if you want the tile line scrubbed.
- Why do some pool cleaners show N/A for cable length or battery runtime?
- Those fields are mutually exclusive. A cordless cleaner has no cable, so cable length is N/A. A corded cleaner runs from mains power, so battery runtime and charge time are N/A unless the manufacturer publishes a real value.
- Is a list price the price I will pay?
- Not always. RobotMatchup records the manufacturer's list price; retailers may charge more or less.
- Has RobotMatchup tested these pool cleaners?
- No. RobotMatchup does not physically test products. Every figure comes from the manufacturer, and anything the maker does not publish reads Not published rather than an estimate.
