Why Pentair KREEPY KRAULY PROWLER 920 Swimming Pool Vacuum does not climb walls?
- KKyle RobinsonJul 29, 2025
If your Pentair Swimming Pool Vacuum isn't climbing walls, several factors could be at play. It might be too heavy due to a dirty cartridge, so try cleaning and washing the cartridge. Algae on the walls can also prevent climbing, so brush the walls. Ensure the water temperature is between 54-90° F (12-32° C). Trapped air can make the cleaner too light, so turn it upside down underwater to release any trapped air. Also, check that the pH level is between 7.4 - 7.8, with a minimum of 7.2.
