I love the BIG GREEN MACHINE.. I have beige carpets throughout my house. It does a great job removing dirt from high traffic areas . I've used a lot of carpet cleaning machine in the past. Nothing compare to the Big Green no even Rug Doctor...Don't spend your money on the cheap carpet cleaning machine ... it's leaks water and leaves stains on your carpet. Pay a little more for a quality machine... it pays off in the long run.
