How To Stop Roomba From Squeaking? (Easy Fixes)

Last updated on January 20th, 2024

The squeaking noise from a Roomba can literally tempt you to throw it out the window. It’s unbearable to hear the constant sound while it cleans. You can’t throw it out the window because it is crazy expensive, so you would rather fix it. There are simple fixes to prevent your Roomba from making loud, screeching noises. Let’s see what that is.

So, how to stop Roomba from squeaking?

Clean and lubricate the Roomba! The sound could be coming from either the wheels or the brushes. Identify the source of the sound and make sure you clean it thoroughly. If that doesn’t stop the sound, lubricate that section with a suitable lubricant. Don’t use oil, as it isn’t compatible with the device.

Identify the sound source

To stop the Roomba from squeaking, you have to first identify where the sound is coming from. It could be from any one of the following parts:

  • Main wheels
  • Castor wheel
  • Side brush
  • Main brushes
  • Dustbin

You must pinpoint where exactly the sound is coming from and focus on that part. It might seem overwhelming to check all these sections. But it isn’t if you follow our below instructions carefully.

Step 1: Start by checking the most accessible part: the side brush. Turn your vacuum upside down and rotate the side brush with your hand. Did it squeak?

Yes? – you found your culprit. No? – move to the next part.

Step 2: Time to look at the front wheel. It’s the most common reason for that nerve-wrenching squeaking sound. Rotate it with your hand. Did it squeak?

Yes? – you found your culprit. No? – move to the next part.

Step 3: Move on to the vacuum’s main wheels. Somehow, debris gets stuck inside the axle, and that’s what causes the friction and squeaking sound. Again, you know the drill – rotate them with your hand. Did it squeak?

Yes? – you found your culprit. No? – move to the next part.

Step 4: Don’t start to get nervous now; you are almost there. Open the main brush assembly and try rotating the extractors. Did it squeak?

Yes? – you found your culprit. No? – move to the next part.

Step 5: Now, this is your last hope to discover the source of that squeaking sound. If all of the above checked out, it must be the dustbin. An improper alignment or a loose spring could cause that sound. Remove the bin and replace it correctly. Ensure all of its parts are where they should be. Now run the Roomba. Did it stop squeaking?

Yes? – you found the culprit. No? – Don’t lose hope. Contact the iRobot Customer Care; they’ll help you sort it out.

Now, if you were successful in identifying the part that’s causing all the ruckus, let’s see how you can fix it.

Easy fixes for the squeaking Roomba

We will go over each of the above-mentioned parts one by one and see what can be done to fix their performance.

Side brush

First and foremost, get a screwdriver to open the screw on the side brush. Remove it and clean it under the yellow cap. Spray/apply some dry lubricant under the cap and place the side brush back into its position. Don’t forget to fix back the screw. This should solve your squeaking problem.

Note: Don’t use oil-based lubricant.

Castor wheel

The castor wheel collects the highest amount of debris around it. And that’s why it needs frequent cleaning. We are sure you must be cleaning it as a part of your regular maintenance procedure. If not, start doing it now. Ensure that the wheel is clean and placed correctly in the position. If it continues to emit the sound, you’ll have to replace it with a new one.

Main wheels

There are three reasons for the main wheels making a ruckus:

  1. Hair and dirt are lodged in either or both wheels’ axle
  2. The axle has become dry and causes friction
  3. The motor controlling the wheels has lost lubrication

For reason number 1, getting rid of the debris should solve the issue. Use regular cleaning methods for this.

There’s a very specific but simple solution for reason number two. If you view a wheel from the side, you’ll notice a small hole in the center. Get a multipurpose maintenance spray like WD-40 and spray it through the hole. Wipe off all the access lubricant with tissues or a towel. And rotate the wheel to ensure free movement. Don’t flip the vacuum until the lubricant has completely dried.

Caution: All lubricants are not suitable. You can either use a graphite or silicon-based dry lubricant. Or a multipurpose dry spray like the WD-40. Wet lubricants are a big no.

Now, the third reason is a bit complex to resolve. That’s because you have to take apart the entire wheel along with the motor and then lubricate the motor. We recommend that you don’t resort to this, especially if you are still under warranty. Keep this as an extreme measure to solve your squeaking problem.

Main brushes

The possible reasons the main brushes could cause a squeaking sound are:

  1. Debris is lodged behind the brushes, and their movement is blocked
  2. Rubber extractors are displaced from their gears
  3. The motor responsible for rotating the brushes is displaced

And there are simple fixes to all of these.

  1. Remove the brushes completely and get rid of all debris accumulated around them. Check the axles and brush caps and clean them thoroughly.
  2. Align the brushes properly in their position. Ensure the gears are where they should be.
  3. Move the motor a bit to adjust its position and make sure its performance is not obstructed by any other part of the vacuum.

Is Roomba squeaking covered under warranty?

Yes, Roomba squeaking is covered under warranty. Well, it isn’t directly, but all the reasons for the iRobot’s high-pitched noise are covered under warranty.

For instance, the castor wheel should give exemplary performance for at least one year of the warranty. If it malfunctions before that, iRobot will do the needful so you can avail your warranty benefits. The same applies to all the other parts responsible for the sound.

If your robot is still under warranty, keep your serial number close and call Customer Support to avail the benefits.
