Yes it is true that the bagged Bissell Powerforce vacuum is about $39.92 I believe. The bagless Bissell Powerforce vacuum is about $42, and 15" bagless Bissell Power Force Turbo is/ was $65. See my discussion on those in the "Bissell as Commercial vacuum" thread under Contemporary listings.
Funny story, that I was looking to get a lightweight stick style vac to replace a broken Eureka Widetrack lightweight for older relative. The Bissell PowerForce bagged vacuum at $39.92 was the cheapest vacuum anywhere and I knew that it would have much more power than any lightweight style vac, yet still felt light itself. I got it for her, told her try it out, see what you think, if its too bulky or heavy or anything I'll return it and look into something else. SHE LOVES IT. She will only use it in the house, she won't let her husband use it. She won't let be used on the carpet in the enclosed porch or where her cat hangs out in her "fancy style"
garage. She loves it. I was going to do some quick vacuuming for her one time, but didn't think she would let me use it, so I used my trusty Hoover. We actually got one for ourselves and I like it for a quick vac/ mid week vacuuming. But for my "Works" style full throttle cleaning, I use the canister vac. I am looking to get our Central vac working again it needs a powerhead, I'll be posting a thread on that soon for suggestions.
