Working cleanly thanks to built-in cable: With the Wöhler RM 400 drain cleaning machine, transport, set-up and drain cleaning can be carried out cleanly and quickly. The machine including cable reel is pulled on wheels like a trolley. The plumber pulls the cleaning cable out of the reel on site and pushes it back in after cleaning. During cleaning, the auto-feed assists the insertion of the cable into the pipe. Different drilling attachments can be clicked on very easily with a snap lock. The convenient solution for indoor and outdoor use.
