Abstract
A connecting apparatus connects a wet dry vacuum cleaner in a vertically spaced relationship with a solution tank. Cleaning solution is dispensed from the solution tank to the article to be cleaned, such as a carpet, and thereafter extracted from the article by the wet dry vacuum cleaner. The connecting apparatus allows a pre-existing vacuum cleaner to be combined with the solution tank, or allows the vacuum cleaner to be disassociated from its associated apparatus of the cleaning solution - extraction type cleaning apparatus. The connecting apparatus itself comprises a plurality of elongated arm members extending essentially from a common connection point, and bracket members are attached to each arm member to contact the vacuum cleaner and solution tank for retaining the vacuum cleaner and solution tank in an essentially vertically spaced relationship. The solution tank can be formed as a part of a movable cart-like device with the vacuum cleaner positioned essentially vertically above the solution tank by the connecting apparatus, or the connecting apparatus positions the solution tank essentially vertically above the vacuum cleaner.
