I have a very old, thick burgundy wool carpet that is in excellent condition. However, the hair from my two cats gets 'attracted' to the rug and seems to make a home there. I had to replace my other brand pet vacuum that I thought was doing a great job. I only did a small section of the rug and the dirt container was already half full. What a surprise! I've had Bissell vacuums in the past. And was very pleased with the job they did. I know I'll be just as happy, if not more, with this one.
