we buy this vac because it be a hepa vac for a incredible price . the thing have great suction and the bagless design make I feel like I be waste less and be less hassle by the whole bag removal and disposal process . it go together in about a minute , and it clean we carpet more deeply than they have ever be clean . its a very good machine , especially give the price . really , I give it 4 and a 1\/2 star because it be a great performer but the hepa filter be not washable and that be not make clear by the advertising for the vac . all in all , though , I be very happy with it .
