I be pretty skeptical , but do quite a bit of research , and discover that this vacuum be get a lot of high mark from both consumer and professional reviewer . I have spend two and three time as much for lesser machine in the past . this one be by far the best we have ever use . it suck up way more dirt than the Hoovers and Dysons we have have before . the only con I have notice be 1 -rrb- it do not have great on-board storage for its accessory , particularly the `` paw '' device ; 2 -rrb- if you can call this a drawback , its suction be so strong that it take a bit of effort pull it backward for the next pass . and we have to change the bag more often .
