I have a 3000+ sq-feet two-story house and over the time the carpets upstairs and in the basement reach a point that cleaning is required. I looked around and eyed on these two products:
Given the price difference I can only presume the former is better, but the specs didn't tell too much why is that, except that it has longer power cord and much heavier.
I'd like to know if I indeed need a pro-grade cleaner? Does it do a better job, for example it's capable of cleaning really touch stains while the cheaper one can't?
