Abstract (en)
[origin: US4395794A] A vacuum cleaner intake device formed of a V-shaped housing widening in the direction of working. The housing has a funnel shape nozzle, a fitting at the apex of the nozzle for connection to a source of suction and a pair of arms extending in a V-shape respectively forwardly and laterally of the nozzle. A pair of side walls are provided each having a skid at its lower edge elevating said housing above the floor. A hood covers and defines with the arms and the side walls a collection chamber open at the forward and rear edges. Each of the arms are provided on their bottom surface with a pair of spaced battens defining between them an elongated suction groove open to the collection chamber and extending outwardly through the side wall.
