ABSTRACT:
The present invention relates to vacuum systems and more particularly, to systems for cleaning up waste materials and/or recovering materials which might otherwise be considered waste, particularly in industrial uses. The instant invention includes a means for creating and applying a vacuum to a localized area, means for collecting materials and a pair of annular rings connected by a spacer means arranged so as to prohibit retained materials from entering the vacuum creation means and means for minimizing the amount of ambient noise disturbance including a sound dampening sleeve member and a helical spring member fitted within said sleeve. Additional embodiments of the present invention include mounting the vacuum means on a frame having articulated wheels thereon and a frame arranged to allow the collection means to be dumped. The present invention may also include means for determining the level of any fluid collected within the collection means which is easily observable to the operator of the instant vacuum cleaner.
