She ended up getting rid of the Filter Queen, but I did check that filter too!! The power nozzle motor died, she had it replaced, then the suction unit had an issue she got that fixed, it broke again and she had enough sinking money into it.
I wasn't here for any of that, but I heard. Long story summed up:
I live just outside of State College and worked for these people while going to college. Then I graduated and moved away in January 2006. Well in November 2010, I moved back to the area and actually live with them now. We've remained in contact and I became kind of "extended family."
So sometime between January '06 and November 2010 the Filter Queen had lots of issues. However the cleaning lady that took over when I left was a vacuum abuser. I returned to both the Filter Queen, and Windtunnel Supreme broken and no longer here, one of the Central vacuum power nozzles completely nonfunctional and a Eureka Widetrack Boss lightweight vacuum broken. The other cleaning lady liked to run agitator vacs on bare floors and suction only vacs on carpet, talk about backwards!!!!!! Everything was a mess here!! The workshop building had a Kirby G4 which she thought was too heavy so she wasn't using that at all, so the carpets here weren't getting ANY agitation, just a quick go over with a crappy newer style Eureka Rally canister which broke and I got rid of. Granted the rugs here are very low profile, but in my book, all carpets must recieve an agitator!!!!!!!!!! I'm not a fan of the G4 either but I used it so the place would be clean. When the Eureka Mighty Mite died which the cleaning lady never used so at least that was still here when I returned, I replaced it with the Riccar 1700 power head canister vac, which is posted in another thread on here. This solved all of my problems for the workshop building, until the recent hose break.
