Self-clean design With SOLOLIFT2 macerators there is no need for regular cleaning or heavy chemical cleaners thanks to the clever design of its grinder and tank. The grinder cleans itself after each operation using the water-air mix present, which is both natural and environmentally friendly. The design also ensures that no debris sticks to the tank walls, removing the need for extra filters and eliminating the risk of odour problems Clever tank design A special tank floor design ensures solids are guided swiftly and easily towards the pump. This removes the problem of sedimentation build up in the tank corners and the resulting odour problems that this can cause. Quick & Easy Servicing with the Segregated easy access pump, motor & electronics SOLOLIFT2 are the most service friendly domestic macerator available on the market. The ingenious design separates the motor, pump and electronics from the processing chamber, so repairs and servicing are really straightforward.
