Query: Not impressed

I was so please with this vaccuum when I first bought it. I have a golden retriever and a long haired chihuahua and it sucked up the hair very well. The bad thing was though that I had to change the bucket like 5 times everytime I vacuumed just one room. I have had this vaccuum about 5 months now and I swear it wont pick up anything! I have tried it on every setting and it rolls up little balls ofhair and wont suck anything up. I am very unhappy with this vacuum, dont waste your money. !!!
