Common Causes Of The Shark Error 6 

here are seven possible causes for this type of error:

1. Obstruction In The Brush

The side brush might be blocked by debris, hair, or other objects, preventing it from rotating properly.

2. Motor Issues

There could be a problem with the motor that drives the side brush, such as a malfunction or an electrical issue.

3. Wear And Tear

Over time, the side brush components may wear down, causing the brush to get stuck or not function correctly.

4. Loose Connections

If the connections between the side brush and the main unit are loose or damaged, it can lead to errors in operation.

5. Sensor Malfunction

Many modern vacuum cleaners have sensors that detect brush rotation. If these sensors malfunction, they might erroneously detect a problem with the side brush.

6. Software Glitch

Sometimes, errors can be caused by software issues or glitches in the vacuum cleaner’s control system that wrongly interpret the state of the side brush.

7. Environmental Factors

The vacuum cleaner might be operating in an environment where conditions (e.g., carpet types, surface height, etc.) are causing the side brush to struggle, leading to the error.

Remember that this list is speculative and based on common issues that can occur with robotic vacuum cleaners that have side brushes. For specific troubleshooting steps and accurate solutions, it’s best to consult the user manual of the particular vacuum model.

How Often Should I Clean My Roomba Side Brush

The frequency of cleaning your Roomba’s side brush depends on various factors, including the amount of dirt and debris in your home, the type of flooring you have, and how often your Roomba is in operation. However, as a general guideline, it’s recommended to clean the Roomba’s side brush every 1 to 2 weeks.

If you have pets that shed a lot of hair or if your home tends to accumulate more dirt and debris, you might need to clean the side brush more frequently, possibly even every few days. On the other hand, if your home is relatively clean and you don’t use your Roomba as often, you might be able to go longer between cleanings.

Regularly checking and cleaning the side brush ensures that it can function optimally, prevents blockages, and helps maintain the overall cleaning performance of your Roomba. Always refer to the user manual of your specific Roomba model for manufacturer-recommended cleaning and maintenance schedules.

Pros And Cons Of Not Cleaning Roomba’s Side Brush


  • Maintains optimal cleaning performance
  • Prevents blockages and tangled debris
  • Extends the lifespan of the side brush


  • Reduced cleaning efficiency
  • Risk of debris clogs affecting overall functionality
  • Shorter lifespan of the side brush due to wear and tear

Inspect For Debris

Examine the side brush and its bristles for any tangled hair, threads, or debris. Gently pull out any trapped material with your fingers or use a pair of scissors to carefully cut through and remove tangled items.

Clean Bristles

Use a brush cleaning tool or an old toothbrush to scrub the bristles of the side brush. This helps remove dirt and dust that might be stuck between the bristles.

Regular Maintenance

To prevent frequent build-up, consider cleaning the side brush every 1 to 2 weeks, or more often if you have pets or a particularly dusty environment.

Check Other Parts

While you’re at it, it’s a good idea to check other components like the main brushes, sensors, and dustbin for any dirt or debris. Keeping these parts clean ensures optimal Roomba performance.

Things To Consider Before Replacing Roomba Side Brush

Before replacing your Roomba’s side brush, there are a few things you should consider:

Cleaning and Maintenance: Before replacing the side brush, make sure you have thoroughly cleaned and maintained it according to the manufacturer’s guidelines. Sometimes, cleaning can resolve issues with the side brush’s performance.

Visual Inspection: Examine the side brush closely to identify any visible damage or excessive wear. If the bristles are frayed, bent, or damaged, it might be time to replace the brush.

Performance Issues: If you notice that the side brush is not rotating properly or isn’t effectively sweeping debris, this could indicate a problem with the brush itself. If cleaning doesn’t improve its performance, replacement might be necessary.

Noise or Vibrations: Unusual noises or vibrations coming from the side brush module could indicate internal damage. If cleaning and maintenance don’t resolve these issues, replacement might be the solution.

Frequent Tangling: If the side brush frequently gets tangled with hair, threads, or debris despite regular cleaning, it might be more practical to replace it, especially if the tangling affects the overall cleaning efficiency.

Remember that each situation is unique, and the decision to replace the side brush will depend on factors such as the severity of the issue, the age of your Roomba, and your personal preferences.

Does Factory Reset Help Fixing Every Problem Of Roomba

Performing a factory reset on your Roomba can act as a reset button, wiping away all previous settings and restoring it to its original state. This can be helpful in fixing certain issues that your Roomba may encounter.

However, it is important to note that a factory reset may not fix every problem that your Roomba is facing. While it can be a useful troubleshooting step, it should not be relied upon as the ultimate solution for all issues.

When you perform a factory reset on your Roomba, it can help resolve issues such as connectivity problems, software glitches, or other minor malfunctions. It essentially clears out any errors or conflicts that may have occurred due to incorrect settings or temporary issues.

It is recommended to try a factory reset if you are experiencing persistent problems with your Roomba, as it can often resolve common issues.

However, it is important to keep in mind that a factory reset will not fix more serious hardware problems. If your Roomba is experiencing issues such as motor failure, sensor malfunctions, or physical damage, a factory reset will not be able to fix these issues.

In such cases, it is advisable to contact the manufacturer or seek professional assistance for repair or replacement options.
