This upgraded automatic pool cleaner can help you clean the pool floor and walls in a low-noise and labor-saving way. The complete working system includes a finned style TPU disc, a long-life vacuum diaphragm and adjustable sewage hoses, which needs to be connected to an electric pump (NOT included) to provide suction power. You can turn the regulator valve to adjust the water flow and add weight to adjust the buoyancy. And then leave it in your pool for auto cleaning. The spinning TPU disc is adaptive to pool floors and walls, while the deflector wheel and the roller stabilizer keep the vacuum cleaner stable underwater. What's more, there are complete accessories for convenience. Hassle-free Auto Cleaning: The pool vacuum cleaner with 36-fin TPU disc can suck onto the various surfaces and climb up walls automatically for thorough cleaning. And the deflector wheel can enable flexible movement & prevent being caught in tight corners. Upgraded Cleaning Tech: No gears or flappers. There is only a vacuum diaphragm that provides powerful suction to clean off the small debris, small leaves, silt or sand. The simple yet practical design minimize daily maintenance and reduce mechanical failure. Great Compatibility and Wide Application: The professional suction pool sweeper is suitable for in-ground pools, above-ground pools and self-supporting pools (not for soft wall pools) and applicable to water depth between 75 to 300cm. Tool-free Assembly: No tool is required to assemble the auto pool cleaner. The instruction clearly shows you how to put the main body together and attach it to the pool pump (at least 1/2 horse power). You can adjust the water hose length, water flow speed and buoyancy accordingly. All-included Package: In addition to the pool cleaner, the package also includes a vacuum diaphragm replacement, 2 elbow connectors, an eyelet diverter, a weight, a vac plug connector, a regulator valve and 10 1M water hoses, bringing convenience in adapting to different pool conditions.
