my wife and I have decide several year ago to go with a bagless model also make by Eureka . not a good idea , for we anyway . the dirt cup fill up quickly with we Golden Retriever 's hair and be constantly clog . when I decide to go back to this model that use bag I be a little bit skeptical thinking we be make a move backwards in ` clean technology ' . I be glad we do now though . we have have this machine for a couple of month and it be by far a better unit . this vacuum have not clog once in that time and even with we constant need to pick up West Texas dirt the bag be only about half full in that time . you do need to adjust for carpet height closely to maintain a good suction , but it be very simple to tell when it be not adjust correctly . my only concern have be with the light plastic construction on some part , but I guess that be the trade off you make for a lower price . we also buy the year supply of bag , filter , etc. and after see the retail price of bag around town , we be glad we do . if you do not want to spend the money on Dyson or another high dollar machine , this be a good choice .
