You're welcome, Lainey.
In the event that you and Doug are unable to connect right away, here is some general information:
The stiffer-bristled brushes are for floors and the softer-bristled ones are for rugs and carpets. The U. S. A.'s floor brushes are tan, and the rug/carpet brushes are black; so this may correspond to the lighter- and darker-colored ones in your photo.
You will also need a dry-foam detergent--not an extraction detergent. The dilution ratio is typically 8:1 (water to shampoo), but check the label.
Here are the steps I have used my Model B-8 (vintage U. S. A. Carpet/Floor Beautifier):
1. Vacuum center and edges thoroughly.
2. Test an inconspicuous area to check colorfastness of carpet or rug. (Use a white rag to manually apply undiluted shampoo in a circular motion). If color appears on the rag try a different brand of dry-foam and check it (compare ingredients before purchasing).
3. Treat any spots or stains with undiluted shampoo and a rag using a circular motion. For stubborn stains repeat or try a carpet stain remover.
4. Use your B-22 to work the shampoo into a foam (do a small section such as 4 feet by 4 feet). Be careful not to over-saturate the carpet which will slow drying time and may cause mold to develop or a glued bond to weaken. If you need to stop for some reason, set your B-22 in its storage tray.
5. Go over the entire carpet using the nap-lifters to facilitate shorter drying time (some individuals also like to lift the nap prior to shampooing).
6. Allow carpet to dry completely then vacuum thoroughly once again. Good air circulation can be aided with a fan and/or open windows (if weather is conducive).
7. Rinse brushes and nap-lifters in warm water--or a mild solution such as dish water if extra dirty. Set bristles up to dry and store carefully to keep bristles from becoming malformed.
8. A service tech recommended to me not to store any unused solution in the solution tank which would eventually erode the rubber seal. Instead, store it in a clean empty bottle such as a pop bottle. Rinse out the solution tank and tube.
9. Wipe down the B-22 with a cloth moistened in plain water or a mild detergent solution (top to bottom) prior to storing. Wipe down the cord as needed--occasional sprinkling of talcum powder if it has a cord winder also helps it function properly.
The dry-foam method is effective for regular light maintenance. Carpets and rugs that have been neglected or have had a lot of spills and/or footwear traffic (versus bare or stocking feet) will benefit from an extraction method. For smaller rugs or carpets you may want to purchase a Electrolux turbo rug washer on eBay. It attaches to a tank vacuum cleaner's suction hose and is used in the same way as the triple-brush machine.
Aerus LLC (formerly Electrolux Corporation and Electrolux Canada Limited) may be able to send you an electronic copy of a B-22 manual if it has one on file. As you can see from the photos and information from previous replies on this thread the B-22s are quite similar to other models from the B-20s to the 2101 and 2101As, so one of those manuals would also be beneficial to you.
