I give this a 5*, with a few thoughts.  It works well, cleans well, & I like how the dispenser trigger works.  About 2 months ago I ordered a Hoover Steam Vac Spin Scrub.  It works well, too. But, it's priced better even at Amazon. AND it's actual label states 12amps.  I bought the Spin Scrub for the mother-in-law. That model has a hose and attachments for cleaning stairs, furniture, etc.. Now maybe more power is needed (12amps) when hoses and attachments are added. Maybe. This new C3820 Commercial states 12amps in the Hoover information, BUT it's actually only 7.9amps.  The two seem to work equally well. They seem to be the same weight, but I didn't check that out. This C3820 has an orange and maybe longer commercial grade cord. Everything else seems the same, again, but this one lacks the hoses and attachment tools.  I've had several Hoovers over the years and wish to point out something important.  The Spin Scrub came with a plastic tool to clean out the take up shoot, the C3820 did not. In time the shoot needs cleaning. Also, Hoover now has a small clear plastic window to the right side on the front. Once in a while you need to snap that window off and clean the screen filter right behind it..Hoover got smart and makes it much more accessible.  A dirty screen will very definately interfere with take up suction of your dirty water.  These are very good machines, and I do endorse & recommended Hoover.
