Causes that Force Roomba to Make Clicking Noise?

The reasons that force Roomba to make grinding noise are the following. One of the most commonly reported reasons among users is dust/hairs(usually of pets) stuck in the brushes.

Why roomba making a clicking Noise

Check the Brush Rollers of Roomba

Usually, the common issue is that the hair of pets gets stuck in a Roomba vacuum cleaner. These messy hairs can be very frustrating if they are causing your vacuum cleaner to sound loud.

When your Roomba walks along the floor, it sucks the hairs from the floor and sometimes they get stuck and jam the roller.

In this case, you have to clean the brush roller such that there is no mess in them. The process to clean that is jotted down.

Although Roomba is an effective robotic cleaner. But if you’ve pets it could be as frustrating as you can think. If you’ve pets at home, iRobot recommends(check Tips & How to install section) you clean the brush at least once a week.

These stuck hairs can hinder the brush movement and thus causing the brush to produce a clicking and rattling noise.

Check Wheels of Roomba

The dust stuck on the wheel well might create grinding noise when it is pressed against the floor. And the screeching sound thus produced due to the wheels of Roomba might be irritating.

Battery Issues

Some errors in battery functionality might produce some clicking noise.

Furthermore, if the navigation system or mapping works inappropriately this may cause some beeping or clicking sound in the software, and sometimes it might display some error code.

Error 46: If this error 46 shows it means Roomba doesn’t have enough battery and needs to be powered again.

Check Roomba’s Dustbox

If a Roomba vacuum cleaner has a full dust box, this causes the blockage. Thus, the vacuum stops moving around.

Only it turns on and when not able to move due to full bin, this creates noise.

Solutions to Overcome Roomba Loud Noise

Clean Brush Rollers

There are two types of brushes in Roomba that contribute to cleaning. You have to clean both of them(brush roller and side brushes). Follow these steps to clean brush rollers.

  1. First, turn your Roomba upside down. Pull the plastic levers(yellow or green in color; depending on your model). Then remove the brush by pulling gently from both ends.
  2. Now remove the hairs, you don’t have to clean them very carefully. Just clean visible messy hairs.
  3. If you’ve a brush cleaning tool that came with Roomba, use that to remove hairs instead.
  4. And that’s it. Your brush is cleaned.
  5. Now reassemble the brush roller again.

Now you have to remove hairs from side brushes.

Tool Required: You will be needed a screwdriver to unscrew the side brushes.

  • Unscrew them, clean all of them and attach them again.

Clean Wheels of Roomba

You just have to clean the dust/debris accumulated in the wheel well with some cloth. And that’s it. It’ll be working fine again without any screeching noise because it won’t face that friction again.

Empty the Bin

The full dust box halts vacuum from working. It doesn’t allow it to accumulate dust further and thus dust gets jammed in other parts of the vacuum cleaner.

The best solution is to empty the bin at least once a week. And, if you have pets you should try to empty the bin twice a week because hairy pets shed hairs and Roomba sucks them very quickly. This fills the bin within days.

Why does Roomba make Clicking Noise While Charging?

The first thing to note if your Roomba is producing clicking noise while charging is to make sure your battery isn’t too old. Because rechargeable batteries in Roomba stop performing after 2 years. Then they need to be replaced.

If not replaced, this may cause malfunctioning, and produce loud clicking noise in the Roomba robot vacuum. If the battery has completed its span you should replace the Roomba battery.
