A floor cleaning machine, in particular not - or polishing machine

摘要

The floor treatment machine has at least two circular rotatable brushes for scrubbing or polishing floors, at least one of which is urged towards the floor by a roller on a spring-loaded arm. A circular brush holder (8) of the machine is pressed down by a roller (15) on one end of an arm (18), the other end of which is urged upwards by a compression spring (22), and is pivoted about a central fulcrum (19).
