GROSS STINKY!  The odor "neutralizer technology" is a disgusting smelling pod thing that smells like a gas station bathroom "odor neutralizing technology" mixed with a sweaty teenager who swam in a tub of dollar store cheap cologne.  I could not run the vacuum for more than a few seconds before I was nauseous and getting a headache from the smell.  
The whole vacuum feels cheaply made, which is unfortunate because I really liked the Shark Vertex that quit on me the other day.
