I've owned every cordless sweeper that's been made that i know of....This Shark Sweeper AIN'T what it's advertised to be...first off it sounds like a loud whiny kid's toy and feels of equal quality. It picks up "ok" but nothing like "the Boss" or Black & Decker's cordless older model did. As for it being good at picking up along the sides of floorboards, etc. Blah....nothing impressive. I bought it because i'm in search of the perfect easy vacuum for stairs, well this definitely is NOT it. Spend less - buy the Boss - i've not found one better than it yet....and i've even shelled out [alot of money] for one of those German cordless vacs you see in some catalogs. Now if ORECK would come out with a cordless vac - then we might have something!
