Abstract
An auto brush pressure cleaning system is described. The system includes a first pneumatic brush, a second pneumatic brush disposed to align with the first pneumatic brush adjacent and parallel to the first pneumatic brush, and a computer. The system also includes a first brush pressure regulator electrically coupled to the computer and transmitting a first and a second signal to the computer and a second brush pressure regulator coupled to the second pneumatic brush and the first brush pressure regulator through a first three-way valve and electrically coupled to the computer, wherein the second pneumatic brush transmits a third signal to the second brush pressure regulator and to the first brush pressure regulator and the second brush pressure regulator transmits a fourth signal to the computer. The system further includes a first electro-pressure regulator coupled to the first brush pressure regulator and the first pneumatic brush through a second three-way valve, wherein the first brush pressure regulator receives a fifth signal from the first pneumatic brush and a second electro-pressure regulator coupled to the second pneumatic brush and electrically coupled to the first electro-pressure regulator and the computer, wherein the computer transmits a sixth signal to the second and the first electro-pressure regulators.
