Why is My Roomba Vacuum Bad Smelling

Many things can cause your Roomba vacuum to smell bad. Here are a few usual causes and ways to fix them:

Dirty or Clogged Filters

Cause: Roomba vacuums have filters that catch small pieces of dust and dirt. Over time, these filters can become clogged with the particles they’re meant to capture. When wind is blocked, dust and other particles build up and cause bad odors.

But you can solve it, Look below:


To tackle dirt or clogged issues thoroughly:

  • First, Check the filter after every few times you use your Roomba to clean, especially if you use it often.
  • Second, Follow the instructions for your Roomba model to find out if the filter can be cleaned or if it needs to be changed.
  • Third, If it (filter) can be washed, gently tap to remove any loose dirt, and then wash it as directed. Be sure it’s dry throughout before putting it back in the machine.
  • If it (filter) can’t be cleaned, follow the manufacturer’s instructions to get a new filter.

Dirty Brushes and Rollers

Cause: Roomba’s brushes and rollers are designed to pick up debris from floors. But they can accumulate hair, dust, and other particles, leading to unpleasant odors.

  • Next, Take the brushes and rollers off the Roomba every so often and wash them if they can be washed. If they can’t be washed, follow the cleaning and care directions from the maker.
  • Lastly, Before returning the brushes and rollers to the Roomba, ensure they are fully dry.

Stale Air in the Dustbin Compartment

Over time, your Rambo robot vacuum’s trash can start to smell bad if it has a lot of old air in it. As the vacuum cleans, it fills the trash can with dust, dirt, pet hair, and other bits of waste. When the vacuum isn’t being used, especially for a long time, the particles get stuck in the trash section, where the air isn’t moving. Over time, these stuck particles can give off odors, making the room smell old and bad.


To mitigate the stale air problem in the Dustbin Compartment:

  • After using the Roomba, open the dustbin compartment to allow air circulation. This will help prevent the buildup of stale, potentially smelly air.
  • Use a trash cover or add something to get rid of the smell, like baking soda.
  • Ensure the dustbin compartment is clean and free of debris before storage.

Cause: If not cleaned up promptly, Pet hair and messes can lead to persistent odors in the Roomba. Usually, pet hair and messes start to smell after a day or two, especially if they aren’t cleaned up right away.


To comprehensively manage pet-related odors:

  • When the Roomba (960) has picked up pet hair or messes, it needs to be cleaned well. Make sure to take extra care to remove any pet hair caught in the brushes and rollers.
  • Use vacuum tools or brushes to get rid of pet hair. These can be more effective at getting rid of pet-related dirt and smells.

Dirty Sensors

Cause: When dust and dirt build up on Roomba’s sensors, it can make it hard to move around and cause bad smells.

  • Use a soft, dry cloth to wipe the sensors down to get rid of any dirt or dust. Ensure the sensors are clean to keep the vacuum’s tracking correct and its parts from wearing out too quickly.

  • Overheating Motor
  • Clogged Brush Rollers
  • Worn-out Components
  • Electrical Problems
  • Battery Issues

Environmental Factors

Cause: The environment in which the robot Roomba is stored can impact its smell. Storing it in areas with strong odors, like a garage or basement, can lead to odor absorption.


When not in use
