After rolling your bowling ball down the lane, and attempting to knock over as many pins as you can, the ball will then go through a tube of some sort and it will then go through a machine that is known as a professional Resurfacing Machine and can be any brand or quality.
After the pins are knocked down the bowling ball goes into a shoot and onto a conveyor system that is located under the lane. The ball is conveyed back up the lane and is sucked up by the bowling ball return system. Other names are bowling ball retrieving device or resurfacing machine.
