Questions and answers
why doesn't my cleaner Dolphin go up the walls?
This is generally due to three main causes:
- Saturated filters: even if they appear clean, invisible fine dust can clog the pores. Try a short cycle without filters (under supervision) to rule out this fault.
- Wear of tracks/brushes: If the rubber pads are smooth or worn out, the robot slips and does not pull.
- Water chemistry: An imbalanced pH or the presence of incipient algae on the wall makes the surface slippery.
when should I change the filters?
The spring filters (grid baskets) last for several seasons, but the ultra-fine panels are more delicate. If you notice that after washing them the robot still does not vacuum well or the cycle is shortened, it is time to replace them. It is recommended to keep a spare set on hand at all times.
is it difficult to change the tracks or belts myself?
Most of the "consumable" changes (tracks, brushes, filters) are simple and do not require complex tools (DIY - Do It Yourself). However, for engine changes or internal repairs, we strongly recommend using our Official Technical Service to maintain the equipment's watertightness and warranty.
are the E-Series parts suitable for the S-Series?
Some do (like certain filters or basic transformers), but most mechanical parts (housings, rollers) are different. Always check the compatibility list on the product sheet or ask us before purchasing.

Types of Spare Parts Dolphin Essential for your Robot
To facilitate your purchase, we have classified the most demanded spare parts according to the critical function they fulfill in your automatic robot.
1. Filters and Filter Baskets
The heart of cleaning. With continuous use, panels and bags lose microbial retention capacity.
- Spring Filters (Coarse): Ideal for seasonal start-up or when there are large leaves and visible dirt.
- Ultrafine Filters: Essential for daily maintenance; they are capable of retaining fine dust, pollen and particles of a few microns.
Tech Tip: If your robot "releases" dirt when you take it out of the water, it is very likely that the non-return valve (gate) of the basket needs immediate replacement.
2. Brushes and Cleaning Rollers
Traction and the ability to remove algae depend entirely on these items.
- PVC brushes: The standard for most pools (reinforced sheet, painted concrete). They are durable and effective.
- Foam Brushes (Wonder Brush): Specific for very slippery surfaces such as vitreous china or smooth ceramic.
- Combined Brushes: A mixture of PVC with foam rings to improve grip on mixed surfaces or old stoneware.
3. Tracks and Tracing Straps
If your Dolphin moves slowly or skids, the problem usually lies here. Tracks and belts stretch or wear out under the action of chemicals in the water, losing the tension needed to climb walls.
4. Electronics: Cables and Power Supplies
Critical components such as the floating cable (with or without Swivel system) or the power supply (transformer).
Note: Many misfires do not come from the motor, but from an internally damaged cable or a faulty power supply due to electrical surges.
Comparison Chart: Which Brush Dolphin Do I Need?
Choosing the wrong brush is the number 1 cause of the robot not going up the walls. Use this quick guide to get it right:
| Brush Type | Recommended Surface | Main Advantage | Wear Level |
|---|---|---|---|
| PVC (Sheets) | Liner, Concrete, Polyester | High durability and all-terrain cleaning | Low |
| Foam (Wonder) | Gresite, Ceramic very smooth | Maximum adherence (grip) for wall climbing | Medium-High |
| Combined | Old or mixed gresite pools | Balance between grip and durability | Medium |
| Active | All models (rotates at double speed) | Powerful algae descaling | Under |
Professional Maintenance Tips for your Dolphin
As technical experts, we recommend you to follow these guidelines to extend the life of your spare parts and avoid unnecessary visits to the workshop:
- Impeller (Propeller) Cleaning: At least once a month, check the water outlet propeller (top). It is very common that hair or dirt strands get entangled there, forcing the motor and reducing the suction power.
- Floating Cable Care: Never wrap the cable tightly around the robot ("bending"). Spread it out in the sun - if possible - from time to time so that it recovers its linear shape and avoid sudden jerks when taking the robot out of the water.
- Water Removal: Do not leave the cleaner in the pool permanently. The chemicals (chlorine/salt) degrade the rubber and plastics prematurely. Always store it in its cart or caddy in the shade.
- Washing Filters: Don't wait for them to dry. Clean the panels or bag with pressurized water immediately after each cycle to prevent dirt from becoming embedded and calcifying in the pores of the fabric.
have doubts about compatibility?
Don't buy blindly. The Dolphin robots have many variants (E10, E20, Seamaster, Poolstyle, etc.) that share some parts, but others are unique.
