1. The Gears May Be Dusty and Working Slower Than Normal

Like most machines, the Roomba may get worn out after a lot of usage. This generally happens after you have used it to clean your house many times.

However, this is to be expected, so do not fret if your Roomba begins to malfunction slightly.

You can locate the side brush on the bottom of the Roomba. There may be some rubbing of the plastic and metal parts that comprise the side brush at that location. 

Additionally, there may be internal grinding located within the gearbox of the side brush itself. This is a familiar noise to hear, and it is nothing to worry about.

Both of these are causes for the irritating squeaky sound you hear. Now it’s time to fix it!

WD-40 is a very commonly used lubricant that helps solve lots of issues with squeaky machines.

  1. Turn the Roomba upside down.
  2. Take off the back cover of the Roomba.
  3. Remove the side brush that is squeaky. It looks like a windmill with three long arms.
  4. You will now see the gearbox for the side brush.
  5. Get a hold of a screwdriver; any simple one will do.
  6. Carefully unscrew the gearbox and place the lid to the side.
  7. Now you will see the intricate gears inside.
  8. Take the WD40 and gently apply it between the gears.
  9. Put the gearbox back together just as it was before.
  10. Now turn on your Roomba and let it do its magic around the house and all your rooms.

2. The Side Brush May Be Dirty and Needs Some Deep Cleaning

Sometimes things will get dirty and forgotten. If this happens to your Roomba, do not feel bad. 

It just means it is time to do some deep cleaning! After all, if you want your Roomba to take care of your house, you need to take care of it first.

The brushes and extractors located near the side brush may have become dusty and filled with unwanted dirt. 

No problem! There is a quick fix for this and, once you do it, your headache will be solved.

How To Fix the Problem

All you have to do is grab something small, like some sort of a brush. You don’t need to get too fancy here and purchase extravagant cleaning utensils.

In order to find the brushes and extractors, turn the Roomba upside down. 

All of the mechanics of the machine are located underneath.

The brushes will be relatively easy to find.

The extractors are the rubber interior that is in the shape of a cylinder. Or it may look like a cylinder covered in bristles, depending on what edition of the Roomba you own.

Once you are ready to clean, follow the steps below.

  1. Find the two yellow tabs.
  2. Pull them up to remove the brush guard.
  3. Grab your small cleaning brush and get to work! Be sure to remove all of the dirt, hair, and debris that you see, and make sure to be very thorough.
  4. You will see tips at the ends of the bearings of the brushes. Take these off and do a deep clean there as well.
  5. Once you are satisfied with the cleaning, put everything back together.

Now you will not only have a better chance of eliminating the squeaky noises, but you will also have a super clean Roomba!
