Abstract
A vacuum cleaner attachment which can be connected to a dry vacuum cleaner to convert the dry vacuum cleaner into a wet vacuum cleaner such that a liquid can be removed from a surface. The vacuum cleaner has a vacuum source for drawing an air stream through an inlet and exhausting the air stream through an outlet. The attachment comprises a housing including a passageway having a first end and a second end in fluid connection with the first end, and a coupler on the first end for coupling the first end with either the inlet or the outlet of the vacuum cleaner so that the air stream produced by the vacuum source passes through the passageway. The housing also includes a reservoir and an intake nozzle. The passageway has a restricted passage portion between the first and second ends including an opening in fluid connection with the reservoir such that when the air stream passes through the passageway, the restricted passage portion produces a vacuum in the reservoir thereby drawing the liquid from the surface through the intake nozzle and into the reservoir.
