An adaptive suspension for a rotary cleaning machine includes a hub ring configured to receive a hub member, a plurality of rigid arms that extend radially from the hub ring and each have a proximal end rotatably connected to the hub ring and a distal end configured to be rotatably connected to a suction shoe, and a plurality of flexing arms that extend radially from the hub ring and each have a proximal end rotatably connected to the hub ring at substantially the same angular position as a rigid arm and a distal end connected to the same rigid arm at a radial distance from the proximal end of the rigid arm. The adaptive suspension adapted for use in a rotary cleaning machine and enables independent upward and downward movements of the suction shoes over an uneven surface.
