The equipment comprises in combination: a floor cleaning machine with cylindrical rotary brushes (10) composed of essentially radial bristles (10A); and, on the side of this machine, a series of guide members - such as shoes with runners and/or spaced-out rollers (16), with annular ridges (16B) - that are able to engage in the grooves (3) of the step, in order to guide the floor cleaning machine while the bristles (10A) pass into said grooves. |
