I just got mine today and started on my living room area rug. 
Packaging/ Assembly: 10/10 was pretty easy to put together.  Literally only like 4 pieces to put together.
Noise level: no score just as loud as any other carpet cleaner. 
Tank Usage: 8/10 easy to fill and clean tanks. The only "con" is the dirty water tank needs to be emptied more. (Ex: my area rug is an 8×10 and I had to empty it three times) but again super easy to empty and refill. 
Solution Samples: 1000/1000 SMELLS AMAZING!! Cleaned very well. One can is I wish they gave a larger sample size. 
Overall: 9/10 Easy to put together, easy to clean, normal noise level and the solution is AMAZING. 
I clean my carpet at least once a month and this did such a better job! My rug looks brand new. The dry only setting was good just next time I'll know clean half then dry it.  Honestly I was just so excited to use this!
