Abstract
A multi-use floor tool, with which the same nozzle can be used in both dry and wet vacuum operation, and which allows for both wet and dry cleaning attachments to be easily attached and removed is disclosed. One such cleaning attachment for dry operation is a bristle brush which, when attached to the nozzle, is able to rotate, such that debris is collected with both the push and pull cleaning motions and such that for each motion, air flows primarily through the side of the nozzle at which debris is being gathered. The attachment for wet operation is a squeegee, which is rigidly attached to the nozzle having an insert which reduces the area of air flow into the nozzle and thereby increases the effectiveness of wet cleaning. This design increases the effectiveness of both wet and dry operation, and allows the operator to effectively clean in both wet and dry conditions while using the same nozzle.
