I just buy this vaccuum last week and after several hour of use I be very pleased with it . I have never use a Dyson so I can not compare the two . however , unless the Dyson miraculously go around clean all by itself while you be at work , I do not know what I be miss out on with this Eureka . I spend a couple hour research vaccuum and read review before purchase . the 3 biggest criterion that influence my purchase decision be the ability to do a good job of clean both carpet and hardwood floor , suction power , and price . the 4870 do a great job on my carpeted floor and hardwood . you can disable the roller brush for when you be use the vaccuum on hard flooring . this be a great feature . as I have a lot of hardwood I would not have buy a vaccuum without this feature . read review of other vaccuum , I see that the exhaust blow out the front and scatter the dust bunny that you be try to suck up . I have not have this problem at all with the 4870 . it have great suction power and I like the power paw attachment for clean my sofa . when the handle be in the upright and lock position the vaccuum 's floor brush roller be disabled . this be another nice feature since you do not want the brush run constantly in one spot of you carpet while you be use the handheld hose and attachment . finally , I think it be a great value for a small price -lrb- I pay $ 140 -rrb- and I recommend it !
