Query: Worst we've ever owned

This is the worst vacuum we have ever owned. It was advertised as being designed specifically for pet hair, but I am not sure what kind of pet. It sure doesn't work well for our long-haired Shepard. It has not worked well since day one. The filter has to be cleaned constantly and I have to empty the cannister several times every time I use it to get any kind of suction.Besides not picking up dog hair very well, it is extremely awkward to move around the house. It is heavy and bulky. You need some real muscles to use this one.I have owned cheaper smaller vacuums that worked better. As a matter of fact, my Dustbuster stick vacuum has more power than this one.This vacuum is NOT worth the price and I am sorry I chose it.
