Abstract: The invention provides an endless rotary band cleaning device comprising an endless cleaning band mounted on three rollers disposed parallel to each other, namely: a drive roller, a guide roller and a secondary roller disposed in the space between the other two rollers. These rollers are arranged so that the lower part of the band follows a sinuous path comprising an upgoing path in which the band is washed and a downgoing path after which the band is impregnated with cleaning liquid. The upper part of the band situated between the drive roller and the guide roller serves as cleaning area.
