FIELD: sucking brush is assigned for vacuum cleaner. ^ SUBSTANCE: it has body fulfilled with possibility of communicating with dust catching arrangement and having at least one sucking opening , cover for closing upper part of body and at least one rotating rod fulfilled with ensuring installation with possibility of rotation on lower part of body. Lower part of body has at least one directing dust chute assigned for direction of garbage and air to sucking opening. At least one rotating rod has cylindrical section assigned for contact with cleaned surface and creation of gap between lower part of body and cleaned surface , and connecting lugs fulfilled in such way that they are projected from opposite ends of cylindrical section and with provision of joining with possibility of rotating in lower part of body. On periphery of rotating rod there is groove having at least one spiral section. On end section of dust directing chute or nearby there are connecting grooves into which indicated joining lugs are put in. Between connecting grooves and connecting lugs there is gap forming channel for air and garbage coming from inlets of dust directing chute. Vacuum cleaner has at least one indicated sucking brush, at least one dust catcher, arrangement for separation of at least one sucking brush from cleaned surface and at least one directing chute assigned for direction dust chuck by at least one sucking brush into at least one dust catcher and fulfilled nearby with lower part of sucking brush. Arrangement for separation of sucking brush from cleaned surface has at least one rotating rod having connecting lugs. ^ EFFECT: improves maneuverability of brush at constant sucking effort due to reducing adhesion force with cleaned surface. ^ 5 cl, 8 dwg |
