Doing all the hallway carpets in a highrise today. Decided to use my Sprayborg since it is all carpet tile. Made $900 before noon then took off to pick up some rugs. I will finish tomorrow for a total of $1800 for aprox 6 hours labour and 2 hours driving time. The Sprayborg is so fast and easy and effective on commercial carpet. I have 3 more similar highrises in the next 2 weeks.
