I have two dogs who shed like CRAZY and I have blue carpet and their fur sticks out and my vacuum just is not picking it up. What vacuum works the best?
Definitly a Rainbow, a little pricey, but you can find a used one if you try.
If you have budget, buy robot vacuum.
My favorite vacuum by far is Oreck. I have owned ours now for 7 years and it still works great! I loathe bagless vacuums because the dirt STILL has to be bagged and dumping the canister into another bag was horrid. The dirt and dust goes airborne creating a bigger problem than you start with! Oreck bags are worth every penny. They have a special way of sealing as you pull them out of the machine. I could go on and on. I love my Oreck. You can visit any Oreck store for a live demonstration. Just tell them you window shopping for vacuums. :) No I don't work for them. I'm just a happy homemaker who finally found a great vacuum! :)
