Device for a Ringformed Scraper Intended for a Floor Treatment Machine

Abstract

A device for a scrubbing-liquid scraper ring for a wet-scrubbing machine having a motor-driven rotatable brush. The scraper ring includes a plurality of flexible blade members that are tilted in relation to the ring's circumference and intended rotational direction and that are held in place in the scraper ring by respective quick-attachment mechanisms. A quick-attachment mechanism includes a manual actuation part and an attachment part that cooperates with a respective flexible blade member, and the attachment part is configured to move between a holding position and a releasing position.
