Vacuum Scents
Most vacuums get a smell over time. You are removing dirt from a rug along with germs, bacteria and other things. Then that dirt festers in a dark, humid, warm closet inside that machine with more dirt being added on a regular basis. Darkness, moisture and warmth create the perfect elements for the growing of germs, dust mites and other things. The smell of vacuums come from the festering of dirt and germs. Unless you were changing the water like in a Rainbow, or had an Activated Charcoal cone filter like on a FilterQueen then any vacuum can smell. Replacing a bag generally eliminates this along with maintaining a clean pre-motor filter, which us collectors know very much about but many consumers ignore!! Kenmore HEPA bags will help reduce this odor along with scented tablets that you can get from Sears, Home Depot or manufacturers like Oreck, Electrolux, FilterQueen or other manufacturers scents.
I highly recommend the Micro Clean tablets that you can get from Home Depot, they are cheaper than Sears and smell very close if not exactly like the Hoover Tablets of years ago. I wish Hoover still produced packages of their tablets. I also miss the Vacuum Puffs scented beads that I could find years ago. That company available from many dollar stores came in Fresh Outdoor, Lemon, Georgia Peach, Vanilla, Apple Cinnamon, Pine and a few others. They were the best!!!!! Really wish they were still available.
