I have a central vacuum system in my house, but would like a regular stand up style vacuum cleaner for quick jobs. I feel Dyson is 50% paying just for the name Dyson. What is the best way to get a strong vacuum cleaner? Do you go by Amps? Reviews? I have a dog that sheds so it should be pet friendly. I would like to stay under $100. I was looking at the Walmart Bissell Power Force model 17003. Any thoughts?
