ABSTRACT:
A bi-directional squeegee jet wand for hard floor cleaning applications is disclosed, characterized by use of a pair of laterally spaced elongate vacuum ports, each of which carry a squeegee wiper blade upon its exterior portion which functions to accumulate spent cleaning solution in close proximity to a respective vacuum port during both forward and reverse manipulation of the wand upon the flow surface. A cleaning solution jet bar is positioned between the pair of vacuum ports such that the vacuum ports serve to deter splashing of the cleaning solution during dispensing which jet bar is advantageously removably mounted thereto permit use of the wand solely for solution extraction applications.
