What should I do if the noise of the floor scrubber suddenly becomes louder?

First: The sewage tank may be clogged. During the cleaning process, there are a lot of small garbage on the ground, or the sewage tank has not been cleaned for a long time. In this case, the sewage tank will be clogged. Once the sewage tank is clogged, it will cause air to stagnate, and a lot of noise will be generated during use. At this time, it is necessary to clean the debris in the sewage tank in time and clean the sewage tank every once in a while.

Second: Water ingress into the fan. Water ingress into the fan will damage the fan. Such abnormal operation will generate noise. What should be prevented is not to accumulate sewage in the sewage tank. After each use, drain the water in the sewage tank and clean the sewage tank to prevent water from entering the fan.

The reason why the brush plate position is loud and how to deal with it. The brush plate position is very loud. We need to check two parts: the brush plate and the brush plate motor. If the brush plate is not installed properly, it will collide with the machine and make noise. Another situation is that if the brush plate motor is damaged or in an aging state, the sound will be relatively loud during use.
