I choose Bissell base on my friend 's recommendation and after read the positive review on this particulare model . even though there be negative review , I fool myself into ignore they and I regret the moment I turn it on . 1 -rrb- the unit be very noisy compare to the Electrolux or Samsung that I have use before and sound more like a commercial Grade vacumn cleaner . 2 -rrb- the unit also fail to pick up dust effectively from the wooden hard floor , though the hose attachment do a better job do that . 3 -rrb- the design of the unit would not let I reach under sofa and bed properly due to the bulk , and the hose attachment be too short and small to pick up dust properly . Though cheap , I decide to return it as soon as I could .
