Judson was presented with a challenge.

Mike Ramsey, a good friend of mine and a carpet cleaner for over 30 years, had a customer with a high security issue.
There was no way to keep the doors open while cleaning. Judson Vacuum is a contractor with the U.S Postal Service, so we adapted our vacuum technology to develop a secure way of cleaning this building.























As you can see in the pictures, the vacuum hose's are connected to a valve. This valve has a spring loaded cover that automatically shuts when you remove the vacuum hose. This valve is located on both sides of the wall, one on the inside and one on the outside.
Above the valve is a set of quick couplings. Hopefully Mike will come on and introduce himself and tell you guys more about it.
By the way Mike is running a Judson TNT that is 24 years old.

This can fix problems of keeping the doors open in houses, this give the idea to make a special accessory for windows where you can connect your solution hose and vacuum hose, and you can take it to all the houses.
