The vacuum cleaner was cited as being effective for both damp and dry cleaning. Dry cleaning is a repulsive practice. It was essential that no dust-collecting mechanism exist; instead, a rag is used to gather stray crumbs. Because it leaves stains if the floors are even slightly dusty, having this vacuum cleaner necessitates having a second one for dry cleaning or vacuuming before washing. I can see the parallel! Exceptional, especially at that cost
