We’ve been Shark loyal for the last 7 years. We were needing a new vacuum and just so happened to stumble across this beast. 
I’ve been looking for years for a good canister vacuum but could never decide on one. 
This one has it all. Two different areas to turn off and on (handle itself and the canister), three different suction/power modes, bare floor/carpet mode (all of which is operated right from handle).
Super easy to empty dust bin. Retractable power cord!!!! No needing to wrap it around. Hold down the button and it slowly goes back to its hidden place!!
The roller brush is very different and unique to anything I’ve ever seen. Hair didn’t get wrapped around it.
 No bags, belts or any of that. Filters can be cleaned reused, and then purchase new when needed. Best part in my opinion is how quiet this thing is. Even at the highest suction, it’s very quiet, without losing suctioning performance. I highly recommend this vacuum.
