How Does the Aquabot Climb the Walls?

Ever wondered how the aquabot climb the walls?
Well the standard robotic pool cleaner has a pump motor, a filter unit (usually a bag or a cartridge) a drive motor and a microprocessor. The pump motor draws the water from the bottom of the unit through the filter unit and pushing the water back to the pool through the top outlet of the robot, the dirt and debris that were at the bottom beneath the robotic pool cleaner where drawn with the water, and now stuck inside the filter unit. The drive motor gives the Aquabot directional movement, through the drive belts to the wheel tubes and drive tracks. Once the Aquabot hits the wall, the wheel tubes that are spinning are making the Aquabot change its position from horizontal to a vertical position. until the bottom of the Aquabot face the wall at the same time the pump is pushing the water and forcing the Aquabot to stick to the wall, at the same time the drive motor is giving directional movement to the drive unit (drive belts that are driving the drive tracks and the wheel tubes) and the Aquabot make its way up all the way to the water surface level.
Note: This method is related to most robotic pool cleaner in the market but not all them
