Is your Roomba making a clicking/knocking noise while operating?
Does it randomly stop and tell you to clean the brushes, however they’re already clean?

Tools/items needed:

  • screwdriver
  • white lithium grease
  • toothpicks
  • paper towels

This is a common problem with Roombas.  After months of usage, it will start to build dirt, grime, hair, etc. into the gearbox.  The gearbox contains several gears which can’t turn properly when it is full of dirt.

I’ll blame my problem on my dog, because most of the issue inside my gearbox was hair.  This video shows you how to get into the gearbox.  Once you get into this, you’ll have to do some heavy cleaning.  After that is done, put a little grease on the gears and put it all back together again.

This is a pretty easy fix, but I’ve noticed that this will not prevent dirt buildup in the gearbox again.  So, you will have to clean it out again in about 10 – 12 months.  Or whenever you start hearing the clicking / knocking noises again.

  1. Do you have any more suggestions on how to fix this clicking / error clean brushes, problem?
    Because i just done a very good job of cleaning the gears just like you said, and mine is still doing the exact same thing!
    There was a lot of pet hair in there so i figure that would fix it for sure, but it didn’t.

    Could i have put any of the gears back in the wrong place?I don’t think so? I didn’t mark them because there is only one big gear and one small one, then all the rest are the same, so they should be able to go in any of the remaining spots, correct?
    I also used a spray white lithium grease as the lube, is that ok?

    PLEASE let me know what else it could be.
    Thanks so much!

    1. I removed the bottom cover (4 marked screws including the two for battery cover) and used a flat paint scraper to lift the bottom cover, used a hand vacuum for all surface dirt/dust, then used a METRO DATAVAC ELECTRIC DUSTER Model ED500 to blow any dirt/dust from any place that let in anything that might affect friction. I didn’t disassemble anything other than remove bottom cover.

      I also used hand vacuum, electric duster and baby wipes to clean dust bin and all exterior surfaces. I usually wipe down the rollers with baby wipe, hand vacuum the filter, and use the electric duster to blow air through the filter from the exhaust side after using hand vac to remove dirt from intake side of filter.

      After doing the above, the Roomba was much quieter. I do now hear the clicking, but rarely, not constantly—certainly less than 5% of job time.

      If constant clicking returns, I’ll watch your video.

  2. This worked! Thank you so much! However, while trying to get the tiny screws out on my 2nd Roomba, I stripped one out that holds the green plastic table. Any ideas on what to do?

  3. My problem is I bought replacement brushes from a 3rd party. I’ve ordered from this vendor in the past with no problem, but this last order, the brush is clunking. If I put the old brush in, no clunk. Please help.
