I cleaned 1,500sq/ft two weeks ago at a frat house. It took me a a supervisor 2-hours, I cleaned ...because I didn't want to move furniture or spot. The other crew encapsulated 3,000sq/ft of halls. We needed them to help at a fire packout, so it was either help them finish up or help at the packout. We're told old to help at the packout.
And for your information I have a room full of upholstery to clean Monday and Dan is cleaning rugs then too. We're getting our butts kicked with work and can watch or help.....I'd prefer to watch....but I better help. ; )
