Find Robotic Pool Cleaners That Fit Your Pool

1. Corded vs. Cordless: Pick the Chore You Prefer

Neither power format is automatically the right choice. A corded cleaner can start another cycle without waiting for a battery, but it needs a suitable outlet, adequate cable reach, and cable management around the pool. Follow the manufacturer’s electrical and placement instructions.

A cordless cleaner removes the operating cable from the water, but runtime, recharge time, battery storage, retrieval method, and battery-warranty terms vary by model. Compare those details against the length of your pool and how often you expect to run a cycle.

For either format, compare the cleaner’s lifting weight and retrieval instructions. For battery products, follow charging and storage guidance and check exact safety information, including applicable CPSC recall notices.

Decision rule: choose corded when repeat cycles and avoiding charging are priorities; choose cordless when cable-free operation is worth managing runtime and charging. Cleaning results still depend on brush design, filtration, navigation, pool shape, surface, and stated coverage.

2. Timers, Apps, and Routine Handling

A timer can reduce manual starts, and an app may add scheduling or status controls. Neither feature makes a cleaner maintenance-free: baskets or cartridges still need rinsing, cables or batteries need inspection, and the unit must be handled and stored as directed.

Before paying more for controls, check which functions work remotely, whether Wi-Fi is required, what schedule options are supported, and whether the manufacturer permits the cleaner to remain in the pool between cycles. Optional power-supply upgrades and app features can vary by exact SKU.

If you usually run the cleaner only when needed, a manual start may be enough. If debris returns on a predictable schedule, a timer can be useful—as long as the filter has enough capacity for the interval between cleanings.

3. Match Filtration to Your Debris

Coarser baskets can be easier to empty when leaves dominate. Finer or pleated media may be more useful for silt and other small debris, but it can require more frequent rinsing. Check what is included, what is optional, and whether replacement media is readily available.

The current listings used for this guide describe these exact filtration details. Make sure the exact SKU and included media on the current product page:

• Escape and Cayman: top-load basket systems; check current fine-filter compatibility and what is included.
• Quantum: XXL MaxBin™ and NanoFilters™.
• Premier: Multi-Media™ system with multiple media choices, including a leaf bag.
• Sigma: top-load cartridges and NanoFilters™.
• Clear UV and Clear S: UltraFilter™ filtration; make sure the supplied filter set.

A cleaner’s filter supports debris removal; it does not replace circulation, water testing, chemical balance, or required sanitation. A UV-C feature likewise should not be treated as a substitute for normal pool-care practices.

4. Make sure Floor, Wall, and Waterline Coverage

A floor-only cleaner can be a practical fit when walls and the waterline are handled separately. Wall or waterline coverage may reduce manual brushing, but steps, benches, drains, sharp transitions, and unusual shapes can still need attention.

These are the coverage details shown for the models in this guide; see the product page and your surface material:

• Dolphin Escape: floor coverage.
• Dolphin Cayman: floor and wall coverage.
• Dolphin Quantum, Premier, and Sigma: floor, wall, and waterline coverage.

Choose waterline coverage when it addresses a real maintenance task in your pool—not simply because it appears higher in a lineup. No coverage label ensures that every part of every pool will be reached.

5. Motor Labels and Ownership Factors

Terms such as “residential,” “high-output,” or “commercial-grade” do not by themselves establish cleaning results or service life. Compare the complete system and the conditions the manufacturer lists for the exact model.

Current product listings describe the motor configurations this way; verify the wording and configuration on the current product page:

• Escape, Cayman, and Quantum: residential motor configurations.
• Premier: dual-motor configuration described as commercial-grade.
• Sigma: triple-motor configuration described as commercial-grade.

Also compare brush design, filter capacity, navigation, lifting weight, replacement parts, maintenance access, and current warranty terms. Usage, water chemistry, cleaning, storage, and repair history all affect lifespan; a motor label cannot predict it. Review the current warranty information before ordering.

6. Compare the Dolphin Lineup by Fit

The models below are corded options with different pool-size ranges, coverage, filtration, and controls. The details are comparison notes, not promises. Make sure the exact SKU, pool surface, maximum dimensions, cable reach, included equipment, and purchase details on each product page.

Use these as comparison prompts, not final recommendations. If a pool falls outside a model’s current size, surface, or coverage, remove that model from the shortlist.
