I previously had the shark navigator for over 5 years and it was awesome-  I just needed a new one because I was using my other for dirtier jobs and wanted a new clean vacuum for just my carpets. The old one never lost suction so I wanted another shark. I settled on this one. 
I do not so far think it’s any better than my last. Good though. 
Cons- for the price it’s no better than my 120 shark. 

It kind of seems cheaply constructed.

Too many bells and whistles it’s a bit overwhelming. 

Hose seems to be shorter than normal

Pros- that thing sucks like a champ! 

Quiet and easy to manuever
