AI Technical Summary

Problems solved by technology

While generally speaking these known wet/dry vacuums work for their intended purpose, such as cleaning up solid and liquid debris, there are a few drawbacks with the typical configuration.

One such drawback concerns the size and portability of many of the known wet/dry vacuum cleaners.

Some vacuums are of such a size that their use in smaller areas or elevated areas, such as in attics, closets, and crawl spaces, is not readily possible due to size or weight issues, or is limited.

Another drawback concerns the collection drum used in containing the dirt, debris, and/or liquid material which is vacuumed up by the wet/dry vacuum appliance.

In some instances, such as when cleaning up certain types of particulate or liquid debris, e.g., drywall compound dust, fine sanding dust, or other fine particulate mat
