my wife and I have have this vacuum for at least 2 year , and maybe even 3 , and have be very happy with it . it still have great suction , and work just as well as when we buy it . we have 2 chihuahua in we place , so keep up with they fur seem like a full time job , but this have be great . I do not know if I would recommend this for someone climb up and down stair , because it can be heavy , but in we single story flat it work great . give that we could have spend many time more on a vacuum , I can say several year later that I be very pleased with we purchase !
