Purchased to replace a defective one (same model). Our old man was probably 6-7 years old and stopped working 2 years ago. I used a Dyson instead of a central vacuum. My Dyson broke last week and I've decided to replace the central vacuum turbine rather than pay a few hundred for a new Dyson. This model is spot on. During operation, it makes a terribly loud high-frequency noise. We don't have pets, so I can't comment on pet hair. I have two kids who make a mess and he manages to clean up. In my opinion, my vacuum cleaner Vaculfo Central Vac doesn't suck very well, but it does its job. After years of using Dyson, it's difficult to move forward.
