Dolphin Robotic Pool Cleaner Comparison Guide
Dolphin offers a broad range of domestic robotic pool cleaners, from lightweight entry-level models to premium app-controlled and cordless cleaners. The best model is not simply the most expensive one. It is the cleaner that matches the pool length, surface, shape, debris load, required cleaning coverage and the way the owner wants to operate and store it.
This domestic comparison guide focuses on Pooltronics' residential Dolphin range, including S Series, M Series and Liberty cordless models. It is designed to help narrow the shortlist before comparing individual product pages or requesting advice.

How to Compare Dolphin Domestic Pool Cleaners
Begin with the practical requirements of the pool. Features such as app control, multiple cleaning cycles and cordless operation are useful only when they support the way the pool will actually be maintained.
- Pool length: confirm the cleaner is rated for the maximum length of the pool.
- Cleaning coverage: decide whether floor-only, floor and wall, or floor, wall and waterline cleaning is required.
- Pool surface: surface texture can affect traction, brushing and wall-climbing performance.
- Pool shape: steps, benches, ledges, slopes and unusual corners can make navigation more demanding.
- Debris: large leaves, general dirt, fine dust and sand require different filtration priorities.
- Controls: choose between simple one-button operation, weekly timers, app control and selectable cleaning modes.
- Handling: compare cleaner weight, water release, caddy inclusion, cable storage or battery charging.
- Support: consider spare-part availability, serviceability and access to professional repairs.

Where the Dolphin Skimmi Fits
The Dolphin Skimmi is different from the cleaners above. It is a solar-powered robotic pool-surface skimmer designed to collect leaves, insects, pollen and floating debris before it sinks.
It does not replace a floor, wall and waterline cleaner. It is best considered as a complementary product for pools that regularly collect surface debris.
Best Dolphin Models by Pool Requirement
| Pool Requirement | Models to Start Comparing | Why |
|---|---|---|
| Small pool, simple floor cleaning | S100 | Compact, lightweight and straightforward |
| Small to medium pool, floor and wall cleaning | S1000 | Value-focused operation with broader coverage |
| Medium pool, full-pool cleaning | S150, S200 | Floor, wall and waterline cleaning with simple controls |
| Smart cleaning for a medium pool | S300i, S400, S2000 | App control and broader cleaning options |
| Larger residential pool | S3000, M400, M500, M600, M700 | Larger-pool capability and premium features |
| Cordless cleaning | Liberty 400, Liberty 600 | No floating cable during operation |
| Premium connected features | M600, M700, S400 | Advanced control, navigation and status features |
| Surface leaves and floating debris | Skimmi alongside a floor cleaner | Dedicated solar-powered surface skimming |
Corded vs Cordless Dolphin Pool Cleaners
Choose Corded When
- You want repeat cleaning without waiting for battery charging.
- The pool has a practical location for the power supply.
- Cable handling is not a major concern.
- You prefer a broad range of models and price points.
Choose Cordless When
- You want no floating cable during the cleaning cycle.
- The battery runtime suits the pool and selected mode.
- You have a suitable charging and storage routine.
- Retrieval features and cordless handling provide practical value.
How Filtration Changes the Comparison
Filtration is one of the most important differences between models. A cleaner may move well but still be a poor match if its filtration does not suit the debris in the pool.
- Large leaves: prioritise accessible capacity and easy emptying.
- General dirt: standard filtration may be sufficient for regular cleaning.
- Fine dust and sand: compare fine, ultra-fine or multi-layer filtration options.
- Mixed debris: multi-layer filtration can help separate larger and finer material.
Replacement filters must match the exact cleaner. Pooltronics supplies genuine Dolphin spare parts and filtration components for supported models.
How App Control Changes the Comparison
App control can provide scheduling, cycle selection, status information and manual guidance on supported models. However, the value depends on how often those features will be used.
- Choose app control when remote scheduling and cycle selection improve the maintenance routine.
- Choose a simpler cleaner when reliable one-button operation is preferred.
- Confirm the exact app functions available on the individual model.
- Do not choose a cleaner only because it has more software features.
How Pool Surface and Shape Affect the Choice
Two pools of the same length may need different cleaners. A simple rectangular pool is less demanding than a pool with benches, steps, ledges, slopes or a complex waterline.
- Confirm that the model is compatible with the pool surface.
- Choose stronger navigation where the shape is complex.
- Confirm whether steps and ledges are expected cleaning areas.
- Consider cordless operation where cable movement around obstacles is difficult.
- Use a home demonstration where available to confirm suitability.
Compare Total Ownership, Not Only Purchase Price
The purchase price is only one part of the comparison. A lower-priced cleaner may be the best choice when it matches the pool. A premium cleaner may provide better value when its filtration, navigation or controls reduce maintenance effort in a more demanding pool.
- Check whether a caddy is included.
- Review replacement filter, brush and track costs.
- Consider battery replacement and charging for cordless models.
- Confirm local repair and spare-part support.
- Choose features that will actually be used.
