For safety, this product should be used by adults and kept out of the reach of children. When installing the turbine, place it on the wall or bottom of the barrel underwater and press it firmly into place. When the turbine is working, do not touch the rotating fan to avoid accidents. For better work, install the turbine below the waterline. Do not use power strips, put wires that are too long in the water so that they won't be pulled into the bucket if they accidentally tangle. After washing, do not touch water or clothing unless the power is turned off. 4-speed remote control: left and right cycle cleaning for 20 minutes; cycle cleaning for 40 minutes; ultrasonic cleaning for 15 minutes; automatic cleaning: left and right cycle for 40 minutes + ultrasonic cleaning for 15 minutes. Note: Please install the suction cup on the bottom of the basin or bucket, not on the curved wall. Clothes can be washed more thoroughly. Wipe it as carefully as you would with your hands without hurting your clothing.
