Vacuum Cleaners Discussions

What are the good/bad things about aquiring used vacs? Buying from Goodwill or garage sales or picking up from the curb? I found a Eureka ESP S/P upright but don't know whether to bring it home or leave it @ the curb? It has a Vibra Groomer 2 brush/beater bar metal roller

I've owned a Diesoon canister DC23 Turbinehead; but returned it & bought a Hoover Windtunnel Cyclonic U5780-900 upright; but the brush roll melted @ the belt pulley. Also the handle wouldn't stay locked upright; & the dust bin latch broke (I remove the cyclone chamber & dump out the dirt from top instead of bottom. I HATE the 'bottom empty' dust bins I gave the WT Cyclonic 2 some1 who needed a vac; & picked a Eureka ESP from the curb (I had a few Eureka F&G style uprights) some had wood brush rolls & a few have Vibra Groomer
