How to Test the Brush and Motor of a Robot Vacuum Cleaner

Aug 03, 2023, 11:06am

A robot vacuum can be made up of one or more brushes: some are motorized, while others follow the movement of the robot.

The central brush picks up dust and dirt by rotating with the help of a motor. It happens that this motor is damaged or that the brush no longer rotates.

It is then necessary to test the motorized brush and the motor if the robot vacuum cleaner sucks badly or no longer sucks at all. For that:

  • Check the filters
  • Disassemble the brush
  • Test the engine
  • Check the motor mechanism
  • Reassemble the device

This brush is located below the robot, and can be removed simply by lifting the protective covers.

A robot vacuum cleaner is a fantastic device that can make your daily cleaning chores much easier. However, like any machine, it can sometimes encounter problems or malfunctions. The brush and motor are two essential parts that play a critical role in its functioning. If your robot vacuum cleaner isn’t working as efficiently as it should, it might be time to test the brush and motor to identify the issue. This article will guide you through the process.

Before beginning, please remember to read and understand your vacuum cleaner’s user manual. Different models may have unique mechanisms, so it’s important to familiarize yourself with your specific model.

Also, it is recommended to switch off the device and unplug it from any charging ports before testing or making any modifications. This is crucial to ensure safety.

Testing the Brush:

The brush of a robot vacuum cleaner is the primary part that comes in direct contact with the floor, collecting dust, and debris. Over time, it may become dirty or worn out, affecting its cleaning efficiency. Here’s how to test it:

Step 1: Check for Blockages and Cleanliness

Remove the brush from the vacuum (refer to the user manual for instructions specific to your model). Check if any debris, hair, or thread is stuck, which could impede the brush’s rotation. Clean the brush thoroughly.

Step 2: Check for Wear and Tear

Examine the brush for signs of wear, such as frayed bristles. If the brush seems significantly worn, it’s time to replace it.

Step 3: Test the Brush

Once cleaned or replaced, reinsert the brush into the vacuum cleaner. Turn on the device and observe if the brush is spinning smoothly and without any obstructions. If it is not, there may be an issue with the motor.

Testing the Motor:

The motor is the driving force behind the robot vacuum cleaner’s operation. If the brushes are not spinning, the motor could be the issue. Here’s how to test it:

Step 1: Listen for Sounds

Power on your vacuum cleaner and listen. A functioning motor will typically produce a smooth, humming sound. Any unusual noise might indicate a motor problem.

Step 2: Test the Motor Function

Check if the brushes are spinning. If they aren’t, it could indicate a motor failure. You should also check other functions, like navigation and suction. If these are also not working, it may confirm a motor issue.

Step 3: Check for Overheating

If your robot vacuum cleaner is shutting off or not functioning correctly after a short period, it could be a sign that the motor is overheating.

Step 4: Professional Diagnosis

While these tests can help you identify a possible motor issue, it’s best to get a professional diagnosis for a definitive answer. If your robot vacuum cleaner is still under warranty, reach out to the manufacturer or a service center. If it isn’t, you might want to take it to a professional repair shop.

Remember, regular maintenance can help prevent many common problems. Keeping your robot vacuum cleaner clean, and replacing parts as needed, can significantly improve its lifespan and performance.
