I am overall happy with the machine, taking it spart to clean after using was easy, filling and emptying tanks is easy but charging plate is large and takes up a lot of space we dont have, and cleaning cycle after each use is loud. 
I have attached a photo of the dirty water tank after using this on my kitchen tile floor. I wasn’t happy that the ingredients list isn’t disclosed on the bottle of Shark brand cleaning solution that came with the vacuum so I filled the water tank with distilled water only. 
I was surprised so much dirt came up because I didn’t think the vacuum was working effectively but was pleasantly surprised. We have an old house and the floors are very uneven and i felt it was floating over spots and not hitting the tiles effectively.  When placed onto base to run a clean cycle i felt the unit was very loud.
