8 year ago I be give the hoover windtunnel for my wedding . it never do work as well as I like . so finally feed up i purchase this one . seem to have the best review for the price . im thrill with the purchase . I want to test it , so I vacuum with the windtunnel first and then revacuum with the Boss . all I have to say be GROSS . 1\/2 a bag of dirt and gross in my carpet . im almost embarrassed now . great suction power , and great suction through the hose -lrb- which the hoover have hardly any -rrb- and accessory work great . I like that the brush stop spin for hard floor -lrb- ive have machine keep spin and inevitably spit peice at my foot which be usually bare . -rrb- not a problem with this one . my area rug have never look as good and light and fluffy and soft as they do now . not even know . I blame the Hoover . however , my one complaint be that there be a high pitched noise that by the time im do vacuum my ear be ring . I have read another review say it be loud , maybe this isnt normal , seem more then just regular motor noise . so I might need to trade mine in , but very pleased this last month with how it work .
