Surface cleaners or alternatively known as patio cleaners, are spinning disc pressure washer attachments that spray high volumes of water through nozzles cutting the surface of any dirt and leaving the surface like new. If you have ever used a pressure washer and placed the nozzle close to the ground to see white lines form, a surface cleaner achieves this level of cleaning in a large area, they are fantastic for cleaning porches, driveways, pools and any floor area. RapidG stocks surface cleaners from Karcher, Gerni, Nilfisk and Aussie Pumps.
