Abstract (en)
[origin: EP1152089A2] A motor sweeper comprising a wheeled frame (1) for supporting a height-adjustable brush (2) of horizontal axis, and a rearward-lying dirt collection bin, said brush being rotated by a motor, there being provided means for measuring a quantity indicative of the pressure exerted by the brush on the surface to be cleaned, and mechanical means (100) for adjusting the height of said brush; elastic means (200) are associated with said mechanical means (100) in such a manner that the height of the brush is adjusted by the mechanical means (100) if the value of the quantity indicative of the pressure exerted by the brush on the surface lies outside a predetermined range, and by the elastic means (200) if the value of said indicative quantity lies within said range. <IMAGE>
