For my fellow VLM peeps

In big commercial carpet spaces, I have found the grain of the carpet running diagonal to the walls. So, the carpet traffic lanes soiling will bisect the nap. I modify the cleaning pattern so that I am cleaning in the same direction as the nap, going forwards and back in the diagonal pattern. I found that this helps to reestablish the natural direction of the nap and helps to eliminate the appearance of the traffic lanes.
