The Swimming pool cleaner Evolution EX500 is a semi-automatic pool robot for swimming pools with a flat bottom. The special hose (included with the delivery, Ø 38 mm, length 8,0m) connects to the skimmer or the intake pipe of the filter unit. Once connected, the pool floor will be vacuumed and scrubbed. Filter pump power of at least 5,500 l/h is required for optimal cleaning performance.
