There are a number of different types of pool cleaners and their primary role is to remove debris from the pool. A suction cleaner is connected to the filtration line and utilises the pressure of the pool pump to suck debris from the surface and walls of the pool into the skimmer basket. A robotic cleaner uses a low-voltage electric motor to create suction which removes dirt/debris from the pool. The debris is captured in a dedicated canister (bag) in the cleaner which requires emptying. A pressure side pool cleaner requires a dedicated pressure line which works off an independent pressure pump and is predominantly used in pools with larger debris. The pressure cleaner also has a dedicated bag which requires emptying
