ABSTRACT:
A vacuum cleaner attachment and method of use thereof provides an effective cleaning system for fungi and the like. A vacuum paddle extension enables the attachment to travel into narrow cracks and crevices where fungus may grow and by use of an abrasive and porous pad dislodges such fungus or fungi. When attached to a vacuum system, such as a HEPA (High Efficiency Particulate Air-Filtered) vacuum system, the debris and particulate matter generated by the abrasive process is drawn into the vacuum attachment and into the vacuum system where it is removed from the air which is then expelled by the vacuum system. Better cleaning of surfaces afflicted with fungi, molds, and the like is then achieved in a manner that is safer and more effective.
