What does a robotic pool cleaner clean?
A robotic pool cleaner is a self-contained underwater floor cleaner with an onboard filter. Every model should be evaluated by its stated coverage: some clean only the floor, while selected models also climb walls or scrub the waterline. These robots collect debris after it reaches an underwater surface; they are not a substitute for a surface skimmer that intercepts floating leaves, pollen, and bugs.
Choose by the job, not the feature count
Start with the surfaces and debris you need to clean, then narrow the catalog by power type, maintenance, and budget:
- Pool fit: Start with inground or above-ground, then verify the pool dimensions and surface compatibility.
- Debris and filter: For frequent leaf fall, compare basket access and capacity in our cleaners for leaves. For pollen or silt, compare the included media and available fine-filtration options.
- Required coverage: Choose floor-only, floor and walls, or a model specifically rated for floor, walls, and waterline cleaning.
- Power and upkeep: Decide whether cable management or battery charging is the more acceptable routine for your pool.
- Budget: Compare the coverage you need across models under $500 and premium models; price alone does not establish pool fit.
- Convenience features: Treat Wi-Fi and app control, weekly timers, and swivel cables as tie-breakers after coverage and filtration.
Corded vs. cordless: choose the routine you prefer
Corded cleaners can start another cycle without waiting for a battery, but they need a suitable outlet and a cable long enough for the pool. Cordless cleaners keep a power cable out of the water, but you must compare runtime, charge time, storage, and battery-warranty terms. Neither power type guarantees better cleaning: brush design, filter media, navigation, and stated coverage remain exact. The Dolphin Liberty line is one cordless option; use the corded vs. cordless comparison for a deeper decision guide.
Compare coverage, filtration, and ownership details
Coverage: make sure the exact surfaces by the manufacturer and expect occasional manual attention around steps, ledges, drains, or unusual pool shapes. Filtration: match the supplied basket or filter media to the debris you actually collect, and check how it is removed and rinsed. Ownership: compare cycle time, cable reach or battery runtime, replacement-filter availability, storage guidance, and the exact warranty. A robot reduces routine floor cleaning; it does not balance water, replace the pool's circulation system, or guarantee every corner will be reached.
Compare brands by pool fit and features
Choose by pool fit before brand. Dolphin (Maytronics) offers corded and cordless models, including the above-ground E10, Premier, and Sigma. Beatbot emphasizes cordless, app-based, and multi-zone options. Aquabot offers residential cleaners, while the Dolphin Wave series is intended for commercial applications. The Dolphin vs. Beatbot comparison explains the major pros and cons.
Compare long-term ownership
Look beyond the first cleaning cycle. Compare filter access, replacement media, cable or battery care, retrieval weight, app usefulness, parts availability, and warranty length before choosing a model.
