Yep, I'd say you did very well! I like the idea of that machine; It's a commercial version of Hoover's T-Series vacuums. Just yesterday I ordered a residential T-Series machine and am excited to try it out.
i use it for 3 times i like it so for it make good carpet mark i like it because it basic hoover model and big bin not that loud compare to oreck only thing is pre motor filter. it has fine dust dust on top of the filter no problem it might just to need wash more often
