Abstract
A cleaning tool for a vacuum cleaner system. The cleaning tool has a manifold disposed therein for more evenly distributing a vacuum-like force produced by the vacuum cleaner system to an undersurface of the cleaning tool, thereby increasing the number of dust and dirt particulates that can be picked up by the vacuum force, and thus increasing the efficiency of the cleaning tool. In a preferred embodiment, the cleaning tool comprises a multi-piece housing within which the manifold resides. The manifold includes a pair of outwardly flaring air passageways and is operable to selectively direct the vacuum force from a vacuum cleaner system more evenly across the undersurface of the cleaning tool to improve the pick-up of dust and dirt particles by the cleaning tool.
