Thank you for the information, John. I was just wondering if my friend received accurate information from Aerus. Unfortunately, others have commented that Aerus has not always researched information before relaying it to consumers. In this case, my friend was told that the representatives had just done their own experiment and found that the nap lifters intended for the more recent machines worked on the Model B-8s.
ALL: In doing more research, I would like to amend some of the information in one of my previous replies (#23). I had not realized that the Model B-7s and first Model B-8s (and probably the previous machines from Sweden such as the Model B-3s and and Model B-6s) were only scrubbers/polishers. It seems that the first B-8s to have the "Carpet Beautifier" function debuted around 1965 (those with the starbursts on the shampoo tank, literature, and packaging). I also wonder if that is when the reset buttons were removed from the design?
Moreover, technically the other Model B-8s would more correctly be labeled as "Scrubber-Polisher & Carpet Beautifier". The B-9s and B-10s were more succinctly called "Floor Beautifier", and the 1522s, 1732s, 1739s, S105s, and S165s were simply called "Floor Pro" or "Lux Floor Pro". I apologize for the misinformation and always appreciate corrections.
Amended information:
1961-1965: B-8/Scrubber-Polisher (aqua; T handle)
1965-1966: B-8/Scrubber-Polisher & Carpet Beautifier (aqua; V handle)
