Since you’ve been able to identify the possible cause of the problem, you have to remove the bin from the vacuum compartment and clean it thoroughly.

However, there are other parts you might want to clean as they have a direct relationship with the dirt that is passed on to the bin.

Clean the onboard dustbin

  • To begin, press the bin release button, which retains the bin attached to the Roomba’s body.
  • Remove the bin afterwards. Some dust may fly out as you do it. It is preferable to relocate the bin from a windy location.
  • Next, you’ll see that the bin has a door that keeps the dust inside.
  • Now, tip the bin over your garbage can and shake off all the dust.
  • When you’re sure the trash is empty, look inside for any obstinate bits of dirt, dust, or debris and clean them up.

Remove the Air Filter

After cleaning the bin, you also have to clean other supporting parts since the air filter is directly attached to the bin, you want to ensure that the air filter is also clean to avoid doing extra work.

Anyway, here is how you should clean the filter.

  • The air filter for your Roomba is placed behind the filter door on the dustbin. So, to start, open the filter door to reveal the air filter.
  • After that, take the filter out of the bin. You can do that by pulling a tab to remove the filter.
  • Then, take the filter to the garbage can. Shake and press the filter against the edge of your garbage can to remove the dust in the filter.
  • When you’re certain that the filter is clean, place it in the trash and close the filter door behind it.
  • It’s also a good idea to inspect the filter while it’s being cleaned.

Remove the Full Bin Sensors
