Abnormal movement of a driving sweeper may be caused by various reasons. The following is a detailed analysis of these reasons and corresponding troubleshooting methods:

　　1. Motor problem

　　Motor fault:

　　Cause analysis: The sweeper is unable to obtain sufficient power to travel due to factors such as a short-circuited motor circuit, damaged motor, or burnt motor.

　　Troubleshooting: Check whether the motor wiring is intact and whether the motor is damaged. If there are any abnormalities, replace or repair the motor.

　　Motor overload:

　　Cause analysis: The motor working for a long time or under heavy load conditions causes the overload protection switch to pop up, resulting in the sweeper stopping moving.

　　Troubleshooting: Press the reset safety switch to restore the motor to normal operation. Additionally, avoid prolonged continuous use or use the sweeper under heavy loads.

　　II. Battery Issues

　　Low battery:

　　Cause analysis: The battery is fully drained, unable to provide sufficient power for the vacuum cleaner.

　　Troubleshooting method: Check the battery level, charge it in time, and ensure that the battery is fully charged before use.

　　Battery aging or damage:

　　Cause analysis: The battery has been in use for an extended period or has sustained physical damage, leading to a decline in battery performance and an inability to provide sufficient power to the vacuum cleaner.

　　Troubleshooting method: Replace the battery with a new one.

　　Battery connection issue:

　　Cause analysis: The connecting wire between the battery and the vacuum cleaner is loose or damaged, resulting in the inability of power to be transmitted normally.

　　Troubleshooting method: Check the battery connection wires to ensure they are tightly connected and undamaged. If they are loose or damaged, repair or replace them in a timely manner.

　　III. Controller issues

　　Controller fault:

　　Cause analysis: The internal components of the controller are damaged or malfunctioning, resulting in the robotic vacuum cleaner being unable to properly receive and execute walking commands.

　　Troubleshooting method: Replace or repair the controller.

　　Controller connection issue:

　　Cause analysis: The connection wires between the controller and components such as the motor and battery are loose or damaged, resulting in the inability to transmit instructions normally.

　　Troubleshooting method: Check whether the connection between the controller and each component is good. If there is any looseness or damage, it needs to be reconnected.

　　IV. Wheel issues

　　Wheel damage:

　　Cause analysis: The wheel is severely worn or damaged due to impact, preventing it from making normal contact with the ground, thereby affecting the movement of the sweeper.

　　Troubleshooting method: Check whether the wheel is intact. If it is damaged, replace the wheel.

　　The wheel is stuck:

　　Cause analysis: The wheel was stuck by debris, garbage, etc., causing the sweeper to be unable to walk normally.

　　Troubleshooting method: Clear away the debris and garbage around the wheel to ensure that it can rotate freely.

　　V. Other factors

　　Accelerator malfunction:

　　Cause analysis: The accelerator is damaged or stuck, causing the sweeper to fail to accelerate or move normally.

　　Troubleshooting method: Check whether the accelerator is working properly. If there is an abnormality, replace or repair the accelerator.

　　Fuse is blown:

　　Cause analysis: The internal circuit of the sweeper is short-circuited or overloaded, causing the fuse to melt, thereby affecting the movement of the sweeper.

　　Troubleshooting method: Check if the fuse is blown. If it is, replace it with a new one.

　　Improper operation:

　　Cause analysis: The operator failed to start and operate the sweeper according to the correct operating procedures, resulting in abnormal movement of the sweeper.

　　Troubleshooting: Carefully read the operation manual to ensure that the sweeper is started and operated according to the correct operating procedures.

　　In summary, the reasons for abnormal movement of a driving sweeper may involve multiple aspects, including the motor, battery, controller, sensors, wheels, and other factors. When troubleshooting, it is necessary to inspect these aspects one by one and adopt corresponding troubleshooting methods. If the problem cannot be resolved, it is recommended to contact the manufacturer of the sweeper or a professional repair technician for assistance.
