I think you need to learn how to clean commercial carpets my friend lol !!!!maybe you had a riding TM robot worker type instrument....
on the end of your hose....??????
I am not saying you didnt clean 40,000 sq feet in 1.5 days...
HWE with a wand?????
but the pic you showed doesnt look like commercial carpet ,......
looks like a house........
maybe it was Bill Gates 2.5 billion $$$$
house with 40,000 sq feet????
so let's just say that you're an old fart that can only clean a thousand square feet an hour that's 40 hours straight.
I mean dear word a super Walmart is 108000 square feet on average you're saying you couldn't kleen half of one of those in a day-and-a-half what a joke!!!
I'm in good health but no means Superman.
Those are pics of a rug in the chairman's office I also stated I didn't have time to take pictures.
Oh and maybe if you did not stop take so many pictures you would be more productive!!!
what you need to do is swing by sometime so so I can put you through one of my training programs ( how to clean commercial carpet progressively )
