Abstract:
A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber and opening allows air, dust and debris to be drawn into the dust chamber during use. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber. The filter is preferably made of a non-woven material with a basis weight between about 20 and 70 gsm, and has a thickness less than about 1.0 mm.
