Neato D3 Started making this weird, loud clicking noise

Postby abs9986 » April 2nd, 2019, 8:25 pm

My neato d3 started making this loud, clicking noise. We have had the robot for about 3 years and use about once per week. It sounds like the spinning wheel in wheel of fortune (i uploaded a video).

1. I confirmed it's not the brush. I removed the brush and still hear the noise
2. When I first start the neato, it sounds normal for about the first 5 seconds, then I hear the clicking noise

Not only is bumping rude, but after less than 24 hours, completely unnecessary.

Download the Neato Control program and use the commands to activate each motor to help you identify which motor may be generating the noise.

If you ignore the noise, will is continue to clean?
If no, it may be the LIDAR problem.
If your D3 start and stop 3 times and does not continue to clean, LIDAR problem.

As suggested by @vic7767, use the NeatoControl to start/stop one motor at a time to find out what is the source of the noise. Please note that there is a motor in the LIDAR module.

Upon opening the neato d3, the sound is definitely coming from the motor toward the front, which I think is the brush motor.

Attached to the motor is a little gear which I think spins the brush motor. That gear and the the little nut where the roller attaches - it spins a few times and then it tightens and then loosens back up. I believe this is the source of the issue.

I included a picture of what I'm talking about. So look at the picture on the right. Where I pointed the arrow (the thing that looks like a nut where you insert the brush) - If I spin that with my hand, it will spin maybe 3 times, then it starts to tighten - almost to the point of not moving, but then it loosesns back up again and then retightens. The same things happens when spinning the black circle based on the picture on the left side. It's like there's some issue with the gear inside the motor

Any suggestions?

Pull that unit out (it clips in) and clip it open - you will find a toothed belt inside, and (I'm guessing) a whole lot of crud too...

Are you talking about the motor I.e the picture on the left side or the module on the bottom is picture on the right side?

The module on the right.
Never let a Neato of this type run without a brush. The gear which is used to spin the brush is not centered if the brush is absent. This will destroy the gear.
Open the black box and clean it out. You can add grease to smooth things up. I have a D85 running with a destroyed gear but when grease is applied it still runs without extra noise.
