Automatic wall adhesion and cleaning system

An automatic wall adhesion and cleaning system, comprising a cleaning mechanism and a vacuum-based wall adhesion mechanism, said vacuum-based wall adhesion mechanism comprising a main body, a vacuum suction device, a flexible rubber track and a sealing material, said main body comprising a drive unit at each of two opposite ends thereof, said drive unit providing a power motor, said vacuum suction device being mounted between two opposite side panels of said main body and disposed between the two said drive units, said vacuum suction device comprising a plurality of vacuum suction holes arranged on a bottom side thereof in at least one row, each said vacuum suction hole being connected to a vacuum-creating hole in said vacuum suction device through an air tube and a tube connector, said vacuum-creating hole being connected to a vacuum equipment through a pipe, said flexible rubber track being mounted on two drive wheels at two opposite ends of said main body, said sealing material being bonded to said flexible rubber track to hold therein a plurality of vacuum mounts, said flexible rubber track comprising an elastic sealing edge at each of two opposite sides thereof, a plurality of transmission gears therein and a ventilation unit in air communication with each said vacuum mount at said sealing material, said ventilation unit comprising an air flow slot cut through each transmission gear of said flexible rubber track and a plurality of air holes cut through said flexible rubber track, said main body further comprising an adapter located on a top wall thereof for the connection of said cleaning mechanism;

• when said vacuum equipment is activated, a vacuum suction force is created in said vacuum suction holes of said vacuum suction device, said drive wheels of said drive units at the two opposite ends of said vacuum suction device are rotatable by the respective said power motor to move said flexible rubber track;
• as said vacuum mounts at said sealing material are moved with said flexible rubber track into alignment with the respective said vacuum suction holes of said vacuum suction device during rotation of said drive wheels, said air flow slots and said air holes work in said flexible rubber track, causing said vacuum mounts at said sealing material to generate a vacuum suction force that adheres said vacuum-based wall adhesion mechanism to the building wall to be cleaned;
• during rotation of said drive wheels to move said flexible rubber track, said vacuum mounts at said sealing material are moved with said flexible rubber track so that said vacuum mounts are activated in turn to generate a vacuum suction force;
• as soon as said vacuum mounts at said sealing material are moved away from the corresponding said vacuum suction holes of said vacuum suction device, the vacuum suction force is disappeared;
• when multiple said flexible rubber tracks and multiple sets of said drive wheels are provided, said vacuum-based wall adhesion mechanism is controllable to do forward, backward and steering movements.
