Abstract: The suction head comprises a main body (4); a rotating brush (11) comprising a brush body (12); a motor compartment (19) housed in a motor housing (21) delimited by the brush body (12); a drive motor (17) housed in the motor compartment (19) and configured to drive in rotation the brush body (12) about an axis of rotation; and an air-cooling circuit (41) fluidly connected to the suction chamber (9) and including a first circuit portion (41.1) partially delimited by the drive motor (17) and a second circuit portion (41.2) partially delimited by the motor compartment (19) and the brush body (12) and located downstream of the first circuit portion (41.1).

Abstract: The suction head comprises a main body (4); a rotating brush (11) comprising a brush body (12); a drive motor (17) housed in a motor housing (21) delimited by the brush body (12) and configured to drive in rotation the brush body (12) about an axis of rotation; a bearing support (31) fixed relative to the main body (4); a bearing (28) mounted on the bearing support (31); and a support ring (26) interposed between the bearing (28) and an inner circumferential surface of the brush body (12) and including at least one through hole (44) through which an air stream is capable of flowing.
