Why is my Dolphin Vacuum Cleaner not climbing walls?
- CChristopher LeonJul 27, 2025
If your Dolphin Vacuum Cleaner is not climbing walls, ensure that: * The filter cartridge is clean. * If using the Dolphin at the beginning of the season, use the spring cartridge. * Check if the brushes are suitable for your pool coating and replace them if necessary. * Check if the brushes are worn and replace them if needed. * The impeller area is clean. * When applicable, check that the RCU is set for climbing.
