Let me start by saying I LOVE this vacuum. The attic feature is amazing and makes cleaning the stairs an easy task. I have a large dog and several other pets and the shark makes vacuuming very easy. I used to have a Dyson beast and had to take it apart after every sweep to clean it. Here's my complaint about the shark. It also clogs, but the difference is that clogs are much easier to clean. The self-cleaning roller does not work, see attached photos. I had to pull out the scissors like with any other vacuum cleaner. It gets clogged with hair between the soft roller and the brushroll, but it's as simple as flipping your head and pulling it out. Everything comes out in one piece, like a mini mohican lol. I definitely recommend it but don't expect it to be perfect.
