So happy with this vacuum! We have a golden retriever and other brands can not handle the hair like the Shark. The brush roll has not become clogged or tangled at all. The green indicator light and the ability to see the brush roll without turning the vacuum upside down are very handy. The large rubber wheels roll very smoothly. I like having the hose and attachments always available. But the suction power is the best feature. We keep ours mostly on max but the adjustment is nice for vacuuming the rugs. I waited a while before reviewing to make sure it continued to perform well and it has not disappointed.
