i was in desperate need of a good vacum and got a dyson........ worked absolutely fine for me( after i cut all the damn string off the brush) then after i had it a couple weeks i read a report that said they tested the dyson with other compareable models........... and they were more powerfull and did a better job........ but dyson is the only one that dosent lose suction.
screw em tho my dyson works just damn fine for me
