The floor scrubber bare machine drop test machine is primarily designed to simulate the durability and lifespan testing of the lifting and lowering actions of floor scrubbers during actual use. By vertically lifting an upright vacuum cleaner/floor scrubber, a program-controlled fixing mechanism is used to reach a test height position and instantly release the tested product, allowing it to fall freely and vertically onto a pine board. Through continuous testing of the lifting and lowering actions of the tested product, the durability of the tested floor scrubber is verified. The test machine is highly versatile, easy to operate, convenient to control, and has a low failure rate.
