We often receive many calls for repairs of floor scrubbers. The first sentence is that my floor scrubber is broken, what should I do? When asked what exactly is broken, many practical personnel cannot explain why. Whether it is a hand-push floor scrubber or a ride-on floor scrubber, it is inevitable that it will break down due to frequent use, forcing the cleaning work to stop. When encountering this situation, there is no need to worry. First, figure out where the problem is. Just follow the troubleshooting and inspection steps explained to you by the editor of YOUNISI. You can troubleshoot step by step. Small problems can be solved by yourself. Problems that cannot be solved at least know where the problem is. Timely feedback to the YOUNISI floor washing machine manufacturer can also locate the problem. This not only shortens the troubleshooting time, but also minimizes the impact of the fault and improves work efficiency.

2. The floor washing machine cannot operate:

First, make sure the power supply is connected properly (for battery-type floor scrubbers, check whether the battery and the machine are connected properly; for power-type floor scrubbers, check whether the plug is connected to the power strip and whether the power strip has power.
