I buy the Eureka 4870mz Boss Smart-vac 3\/19\/09 . it be now 7\/25\/09 , and the vacuum be already fall apart . the vacuum be a okay one , but I accept it be shortcoming , because it be cheap enough . it vacuum pretty well across several different floor surface -lrb- carpet , tile , laminate -rrb- , but it be heavy , generate a lot of heat , attachment would fall off all the time , and switching between bare floor and carpet and between hose and floor be unnecessarily cumbersome . as I say I be willing to live with this , because of the price . my previous vacuum have be a $ 400 Dyson which be a nightmare , and I vow never to spend that much on a vacuum again . but now , here I be , just over four month later , and the Eureka be no longer usuable . first , the cheap plastic wheel be fall off . second , the switch that you turn to change from floor to hose no longer work properly , so that now I can not use anything but the hose . basically what I have now be a really expensive dust Buster . my floor be filthy and I can not vacuum . other review have make reference to the cheap quality of this vacuum , and it fall apart after a few month . I should have listen . if you value you money , I would not recommend this vacuum .
