terrible quality : my mom buy this for I at Costco after I have do lot of research . we do not get to test it out because the model be lock in place . it replace my cheap and efficent sharp vacuum that I have use for 12 year . I could not believe how heavy it be . it do not have a direct drive so move it back and forth take effort -lrb- I be a strong person - but my Sharp be s nice and easy -rrb- . after 3 month with use about 1 time a week the hose break and I duck-tape it together . after 6 month the on\/off switch break so when it be plug in , it be on . now a year and half later the carpet aggitator break . I have replace many belt in my year and I replace this belt but that be not the problem . I be happy it break because now I have a excuse to get a good vacuum . do not waste you money .
