The dolly has at least three wheels for conjoint pivoting movement therewith relative to the floor surface treatment apparatus. The at least three wheels are arranged relative to each other such that in the support position of the dolly the at least three wheels stably support the apparatus with the floor surface treating unit raised off the floor. In its non-support position the dolly may be stowed onboard the apparatus during operation thereof.
