unbelievably difficult to push head forward against carpet in order to vacuum,( tried both high and low setting),
 unusable, badly designed, its not that my specific unit was bad.
hard floor might be acceptable? but not carpet.
if it did work, head is narrow, and the inner part that actually vacuums is like 3 inches wide, the vacuum isnt spread across full width. 
I hope I can still return it back to wayfair after trying to use it for 10 minutes.
