发明名称 VACUUM CLEANER HAVING AT LEAST ONE SUCTION ASSEMBLY
摘要 A vacuum cleaner is provided with a dirt collection container and a suction head which can be placed on the dirt collection container, wherein the suction head has at least one suction unit which is in flow communication with the dirt collection container via a suction duct and a filter device and with at least one exhaust air opening via at least one exhaust air duct. To provide high suction capacity, a compact construction, and relatively little generation of noise during operation, the suction head has two suction units arranged next to one another, positioned in a vertical direction at the same level as the filter device and surrounded by a common exhaust air chamber, wherein the exhaust air chamber is in flow communication with exhaust air openings via a first and a second exhaust air duct and the filter device is arranged between the two exhaust air ducts.
