Inadequate Cleaning Performance

Is your robotic vacuum not cleaning properly? There are several potential reasons for its inadequate cleaning performance, but don’t worry – we have covered you. Here are some possible causes and solutions to help improve your robotic vacuum’s cleaning abilities:

👉🏻Dusty or Dirty Sensors

The robotic vacuum’s sensors are crucial in detecting dirt and debris. If dust or dirt contaminates the sensors, it can severely impact the vacuum’s cleaning performance. Clean the sensors regularly with a soft cloth or brush to ensure optimal performance.

👉🏻Worn Out Brushes or Filters

Damaged or worn-out brushes and filters can significantly affect the cleaning performance of your robotic vacuum. Make sure to replace them on time to keep your vacuum working efficiently.

👉🏻Obstruction in the Path

If there is an obstruction in the path of your robotic vacuum, it will not clean properly in that area. Check for any obstacles or clutter on the floor that might block the vacuum’s path. Clear the area before starting the cleaning cycle.

👉🏻Low Battery Charge

If your robotic vacuum’s battery is low, it may not have enough power to clean your entire home. Charge the battery fully before use, and avoid running the vacuum in low power mode.

👉🏻Overused Battery

Using your robotic vacuum’s battery for a long time might not hold a charge. Consider replacing the battery if it does not last an hour during operation.

By identifying and addressing these potential causes of inadequate cleaning performance, you can ensure that your robotic vacuum operates optimally and keeps your home clean and tidy.


To improve the cleaning performance of your robotic vacuum, try the following:

  1. Clean the brush roll regularly and remove any hair or debris.
  2. Replace or clean the filter according to the manufacturer’s instructions.
  3. Check and clean the wheels and sensors, particularly if they appear dirty or obstructed.
  4. Fully charge the vacuum before use.
  5. Move the virtual wall to allow the vacuum to clean all areas.

Addressing these potential causes can help restore your robotic vacuum’s cleaning performance and ensure it operates at its best.

👉🏻Prevention Tips

To prevent your robotic vacuum from experiencing inadequate cleaning performance, try the following:

  • Clean the vacuum regularly, including the brush roll, filter, and sensors.
  • Remove any large or excessive debris before using the vacuum.
  • Keep the virtual wall in a position that allows the vacuum to clean all areas effectively.
  • Charge the vacuum before use to ensure it has enough power to operate at its highest setting.

These tips help keep your robotic vacuum in good condition and prevent it from experiencing cleaning performance issues.

Battery and Charging Problems

If you’re experiencing issues with your robotic vacuum’s battery or charging, it can be frustrating and affect the appliance’s performance. Here are some possible causes and solutions to help resolve the problem:

Battery Issues

  • Check if you properly plug in the battery and securely connect.
  • Ensure the battery is not damaged or worn out, as this can result in shorter battery life
  • If the battery is depleted, let it charge for at least 3-4 hours
  • Avoid charging the battery continuously for extended periods. It will cause damage to the battery.

Charging Problems

  • Ensure that the charging station or dock is plugged in and receiving power
  • Check the charging contacts on both the vacuum and dock to make sure they are clean and free of debris
  • If the vacuum is not charging, try resetting it by unplugging the dock, waiting for a minute and plugging it back in
  • Avoid overcharging the vacuum, as it may result in battery damage

With these tips, you can troubleshoot and resolve common robotic vacuum battery and charging issues and ensure that your appliance continues operating optimally.

Inconsistent Cleaning Patterns

If your robotic vacuum exhibits unpredictable cleaning behavior, it can be frustrating and defeat the purpose of owning one. However, this is a common issue that many users face. This section will explore why your robotic vacuum may have inconsistent cleaning patterns and provide solutions to restore its predictable cleaning behavior.

Potential Causes

  • Obstacles: Your robotic vacuum may encounter obstacles, such as furniture, disrupting its cleaning path. Check the area for objects that may be blocking its path and remove them.
  • Dirty Sensors: The sensors that guide your robotic vacuum may be covered in dust or dirt, leading to confusion in the cleaning pattern. Clean the sensors using a lint-free cloth to restore normal operation.
  • Battery Issues: A robotic vacuum with a low battery or one frequently running out of power mid-clean may lose track of its cleaning path. Fully charge your vacuum’s battery, and consider replacing it if necessary.

How to Fix Inconsistent Cleaning Patterns

  1. Check the environment: Clear the area of obstacles or clutter that may impede your robotic vacuum.
  2. Check the sensors: Clean your vacuum’s sensors with a lint-free cloth to restore normal operation.
  3. Reset the cleaning path: Turn off your vacuum, move it to a different location, and restart it to reset the cleaning path. It may help your vacuum rediscover its cleaning pattern.
  4. Update the software: A robotic vacuum’s inconsistent cleaning behavior can sometimes be due to outdated software. Check for any available updates and install them to improve your vacuum’s performance.

Follow these tips to restore your robotic vacuum’s consistent and predictable cleaning patterns. Doing so ensures that your vacuum operates at its best and keeps your floors clean.

Noisy Operation

If your robotic vacuum produces a lot of noise during operation, this can be quite disruptive and annoying. Several factors can cause the loud operation, and addressing them can help make your vacuum run quieter. Here are some possible solutions:

  1. Check the wheels for debris, hair, or other blockages that may cause the vacuum to make more noise than usual. Clean the wheels and surrounding area regularly to prevent debris buildup.
  2. Inspect the brush roll for tangled hair or debris that may cause it to work harder and produce more noise. Clean the brush roll regularly to avoid this issue.
  3. Replace any worn or damaged parts that may be causing the noise, such as a damaged fan or motor.
  4. Consider using noise-absorbing materials or adding soundproofing to the room where you use the vacuum to reduce the noise level.

Implementing these measures can help your robotic vacuum operate more quietly and make cleaning more peaceful.

Inability to Connect

Connectivity problems can be frustrating when trying to use your robotic vacuum. Fortunately, you can try simple solutions to fix connection errors and get your vacuum back up and running.

Check Your Wi-Fi Signal

Make sure your robotic vacuum is in range of your Wi-Fi signal. If your signal is weak, try moving your router closer to the vacuum or installing a Wi-Fi booster to strengthen the signal.

Restart Your Vacuum and Router

Restarting your vacuum and router can help resolve connection issues. Turn off both devices and wait a few minutes before turning them back on. It can often fix any connectivity problems caused by temporary glitches.

Reset Your Robotic Vacuum

If restarting your vacuum and router doesn’t work, you may need to reset your robotic vacuum. Consult your user manual for instructions on how to perform a reset. Remember that resetting your vacuum will erase any saved cleaning maps or schedules.

Update Your Firmware

Make sure your robotic vacuum is running the latest firmware version. Check the manufacturer’s website for any available updates, and follow the instructions to download and install them.

Factory Reset Your Router

If none of the above solutions work, try factory resetting your router. It will erase your router’s settings and configurations but can help resolve persistent connectivity issues. For further details on how to do a factory reset, see the handbook that came with your router or contact your ISP.

Following these tips, you can troubleshoot common robotic vacuum connectivity issues and ensure your vacuum is connected and ready to clean whenever needed.
