What Are the Common Causes of Loud Noise in Robot Vacuums and the Solutions?
If your robot vacuum is making a loud noise or creating unexpected sounds such as grinding, rattling, or even squeaking, it's important to identify the specific source of the problem. Models like Roomba, Roborock, and Shark robot vacuums are prone to noise issues when there are obstructions, worn-out components, or mechanical faults. Understanding these causes can help you resolve the issue before it gets worse.
Obstructions and Debris
If your robot vacuum is making grinding noise or a clicking sound, check for any debris tangled in the main brush or wheels. Pet hair, string, or large dirt particles can easily cause your robot vacuum to sound noisier than usual and sometimes result in a robot vacuum squeaking or clicking while operating.
Solutions:
- Turn Off the Vacuum: Ensure the robot vacuum is turned off before you start inspecting it.
- Flip It Over: Carefully turn the vacuum upside down to access the brushes and wheels.
- Inspect for Debris: Check for obvious obstructions in the brushes, wheels, or other moving parts. Pay close attention to hair wrapped around the brush rolls or small objects stuck in the wheels.

- Clean Regularly: Make it a habit to check and clean the brushes and wheels regularly to prevent debris buildup.
Worn-Out Brushes or Filters
Brushes and filters are essential for your robot vacuum’s cleaning performance, but they can wear out or become clogged with use. Worn-out brushes may not spin properly, and clogged filters can impede airflow, causing the motor to work harder and make more noise.
Solution:
- Check Brushes: Regularly inspect the brushes for signs of wear and tear. Look for frayed or bent bristles that might indicate they need replacing.
- Replace Brushes: If the brushes are worn, replace them with new ones according the manufacturer's specifications.
- Clean or Replace Filters: Depending on your vacuum model, clean the filters by gently tapping them to remove dust or washing them if possible. Replace non-washable filters every few months, or as instructed by the manufacturer.
- Maintenance Schedule: Follow a regular maintenance schedule to check and replace brushes and filters to keep your vacuum operating quietly and efficiently.
Loose Parts
If you hear a rattling noise or something shaking inside, your shark robot vacuum may be making clicking noise or Roborock making rattling noise. Loose parts, like the dustbin or brush assemblies, are frequently to blame for noisy robot problems. Regularly tightening screws and ensuring all modules are secure reduces these issues.
Solution:
- Inspect the Vacuum: Turn off and flip over the vacuum to inspect all the components.
- Check for Loose Parts: Gently shake or touch each part to see if it’s loose. Common parts to check include the brush roll, wheels, and dustbin.
- Tighten Screws and Fittings: Tighten any loose screws or fittings with a screwdriver or the relevant equipment. Ensure all parts are securely attached.
- Regular Checks: Periodically inspect your vacuum to ensure all components remain securely in place to prevent future noise issues.
Software Issues
Unexpected robot vacuum noise can sometimes emerge after a firmware update or app sync. If your robot suddenly becomes loud with no visible cause, check if your robot vacuum software needs an update. For brands like Roborock, Roomba, or Shark, updating the software can resolve operational oddities and restore quiet, effective cleaning.
Solution:
- Check for Updates: Regularly check the manufacturer’s website or app for software updates.
- Update the Software: To update the software on your vacuum, simply follow the instructions provided. This often involves downloading an update via the app and installing it on the vacuum.

Product-Specific Noise Issues
Not every robot vacuum makes the same sound, and different brands often come with their own common noise complaints. Here’s a quick look at the most reported issues and what you can do.
Ecovacs Deebot making loud noise or clicking
Deebot models often produce a clicking noise when the wheel gears are obstructed or when debris gets caught inside the housing. Clearing tangled hair or small objects around the wheels usually brings the noise down. In some cases, a loose gear may need tightening.
Eufy RoboVac making loud noise
Many Eufy owners report loud humming or vibration. This is usually linked to a loose brush or worn-out fan. Reseating the brush and replacing old rollers often fixes it. If the sound continues, the internal fan may need servicing.
Roomba making loud grinding noise
Grinding noises in Roomba units often point to worn brush bearings or rollers clogged with pet hair. Cleaning the brush module and replacing aged rollers restores smoother, quieter operation. Regular filter changes also reduce the strain on the motor.
Shark robot vacuum making clicking noise
Clicking in Shark vacuums usually comes from tangled hair in the main roller or a side brush that’s not secured. Removing the hair and tightening the brush assembly usually solves it. Keeping the rollers clean prevents repeat issues.
These brand-specific problems are common, and the fixes are often repetitive. If you’re looking for a quieter long-term solution, Narwal Flow offers both power and silence. With 22,000Pa suction and advanced noise-reduction technology under 57dB, it delivers deep cleaning without the constant grinding or clicking that frustrates many robot vacuum owners.
What Are Some Specific Noises and What Are the Solutions to Them?
Different noises from your robot vacuum can indicate specific issues. Understanding these sounds can help you identify and fix the problem quickly. Common noises include grinding or scraping, high-pitched whining, and rattling.
Grinding or Scraping Noise
A robot vacuum making grinding noise can point to stuck debris or misaligned components. This issue is especially common in high-traffic areas or homes with pets. If the problem is not fixed quickly, it may lead to further damage to your vacuum's mechanical parts.
Solution:
- Turn Off the Vacuum: Ensure the vacuum is turned off and unplugged from its charging station.

- Check Brush Roll: Make sure the brush roll is not worn out or damaged. Replace it if necessary.
- Regular Cleaning: Clean the brushes and wheels on a regular basis to avoid debris from accumulating and causing additional problems.
High-Pitched Whining Noise
A high-pitched whining noise usually points to a problem with the motor or the fan. This sound often occurs when there is restricted airflow, which can happen if the filters are clogged or if there is a blockage within the vacuum.
Solution:
- Check Filters: Remove and inspect the filters. If they are clogged with dust or debris, clean or replace them.
- Inspect for Blockages: Look for any blockages in the vacuum’s airway. Remove any debris that might be obstructing the airflow.
- Check Motor and Fan: If the filters and airway are clear but the noise persists, the issue might be with the motor or fan. For additional assistance, refer to the user manual or contact customer service.
- Update Software: Ensure that the vacuum’s software is up to date, as software issues can sometimes cause operational problems.
Rattling Noise
Rattling noises are often caused by loose parts within the vacuum. This could be due to components like the dustbin, brush roll, or wheels becoming loose over time, leading to a noisy operation.
Solution:
- Inspect for Loose Parts: Turn off the vacuum and inspect all parts, especially the dustbin, brush roll, and wheels, to see if anything is loose.
- Tighten Components: Use a screwdriver or appropriate tool to tighten any loose screws or fittings.
- Secure Dustbin and Brush Roll: Ensure that the dustbin is properly seated and the brush roll is securely attached.
- Regular Maintenance: Perform regular checks and maintenance to ensure all parts remain securely in place, preventing future rattling noises.
Robot Vacuum Squeaking
A squeaking sound usually comes from dry wheels or bearings that need lubrication. Over time, dust and friction can make the wheels emit high-pitched squeaks during movement.
Solution:
-
Power off the vacuum and flip it over.
-
Check the wheels and axles for dust buildup. Clean with a soft cloth.
-
Apply a small amount of silicone-based lubricant to the wheel bearings. Avoid oil-based products, as they may attract more dust.
-
Regularly inspect and clean the wheels to prevent squeaking from returning.
If the squeak continues even after cleaning and lubrication, it may signal worn bearings that require replacement. For users who want a quieter alternative without frequent maintenance, models like Narwal Flow, which operates under 57dB with DualFlow design, minimize both friction noise and cleaning effort.
User Experiences with Noise Levels
While manufacturers often list the decibel rating of their machines, real-world experiences tell the full story. On forums like Reddit and product reviews, users frequently compare how loud their robot vacuums actually sound and whether the noise disrupts daily life. Many complaints begin with “my robot vacuum is making loud noise” or “why is my robot vacuum so loud”.
