Abstract (en)

[origin: EP1068827A2] Cleaning head (140) comprises sawn-off cone-shaped cavity. Air spray nozzles (151) comes out in lower part of cavity. Dust extracting windows (161) are located in upper part of cavity. Vertical channels (131), feeding pressurized air to air spray nozzles, are also located in cleaning head. Due to spray nozzles, vortex effect is created inside cavity, close to floor to clean, so that solid or liquid particles are lifted and driven in cyclone inside cleaning head. Due to sawn-off cone-shape of cleaning head, particles are driven to top of cleaning head, to extracting windows, whilst particles discharged air is evacuated through nozzle (171). Nozzle is flared at top so as to ensure air flow distribution over filter (182) situated under suction intake (130A) of moto-ventilator (130).
