I had an experience similar to that of some of the other reviewers. The vacuum cleaner started OK but went downhill quickly. I emptied the dirt cup and cleaned the filter frequently, but it stopped picking up pet hair soon after the first use. I've had it about 4 months and, like the other reviewers' machines, the belt has broken. The store I bought it from doesn't carry the belts. Neither does Target, who also sells this vacuum cleaner. Now I either have to hunt down a belt or pop it back in the box and take it back to the store. Glad I kept the receipt.
