The canister ones are nice for vacuuming up sand and such dirt and that is all they are really better for , but then a cheap wet/dry works better.
When we used the canister one as a house vacuum I got sick and tired of having to stop to go dump out the canister continually, plus if you do not replace the filiters most of those also have or they will burn out.
We have gone through three of the plastic things, which does not include having to buy new belts and rollers/brush which are 50 bucks each.
These were not 200 cheap crap, but 500 plus simplicity/Riccar vacuums.
These get hard use, and now for 500 dollars all you get is a refurbished which to me is now just fine, as new ones are several hundred dollars above that.
the Sig. had little red low buck , now 10 years old one at here beauty shop. IF, if it had attachments one like that was amazing, it would pull itself across the carpet when it was new.
But without attachments it is only good for carpets. (It sucked stuff up so well that it packed it into the bag and beyond. It stopped working once so I pulled the bag out and found it at the verge of bursting, BUT, the handle is part of the dirt transfer hose and it took me an hour to finally get the packed hair out of the handle.
Worked fine after that.)
Get the Kirby fixed, the plastic crap one stop working eventually and cost just as much to fix as a Kirby.
