we have have one for year , we need another one for the second floor as repeat haul up and down the stair have hurt the old one . I have purchase a huge stock of filter and bag for this model so decide to go with it - not to mention that it be still a consumer digest best buy . no issue whatsoever , it be probably a little noisy but we be use to it - have not owner another vacuum model in over 6 year . the additional accessory that have a roller attach to the hose be great for carpeted stair . you can not go wrong with this solid piece of machinery .
