1. The rotary mop cannot rotate by itself

(1) The rotary mop is generally composed of two parts with an interface in the middle. If the mop does not rotate, there is a problem with the interface. Divide the middle part into two parts with a hacksaw. The upper nut is working properly. If it is damaged, you can replace it with a new one and install the mop head.

(2) After using the mop ruler for a period of time, it may also rub on both sides, resulting in its inability to rotate. The solution is to take down the ruler and level the upper and rear teeth of the ruler with a knife. Increase the space on both sides without friction.

2. Rotating mop bucket does not rotate

(1) If the mop bucket does not rotate, there should be a problem with the internal rotating shaft. You can open the bucket and check whether the steel ball in the empty tank is normal. If the steel ball is worn, you should replace it with a new one.

(2) The pedal spring of the mop bucket may also be insufficiently elastic, resulting in excessive friction and locking. You can remove the damaged spring and install the new spring on the snap of the ruler.
