I don't have stairs, so can't rate it on that. I liked my other Shark vacuum more...this one is cumbersome and the power cord is stiff. The duction in the hose is mediocre.

I've had this kind of vacuum before and it works well. Had to buy a new one. The one I received was refurbished, not new, but I didn't even get through my house the second time and the handle broke off. Hoping the next I get in the exchange lasts longer.

Would have given a 5 star rating but the canister broke 1 week after I got it I glued it was doing g good then the canister broke again. In all fairness I called shark up and they replaced it for free and I received it the next day. Working good now.
