The cold water high-pressure cleaner HD 8 / 18-4 M is available in two versions: mobile with large wheels and as a stationary model for wall mounting. The machine is built to last and is thus designed for economical operation. This is evidenced by the automatic pressure relief, the brass cylinder head, a four-pole, predominantly maintenance-free motor and an efficient filter at the water inlet. The large control switch at the front is easy to reach, even during operation.
