Why Is My Roomba Brush Not Spinning – Possible Causes

Why isn’t my Roomba’s brush spinning? This is a common issue that many Roomba owners face, and there can be several reasons behind it.

  • One possible cause could be a clogged brush. Over time, dirt, hair, and debris can get tangled in the brush bristles, preventing it from spinning freely. To resolve this, we need to remove the brush and clean it thoroughly.
  • Another reason for the brush not spinning could be a loose or damaged belt. The belt is responsible for connecting the motor to the brush and allowing it to rotate. If the belt is loose or worn out, it may not have enough tension to spin the brush.
  • It’s also possible that the brush motor itself is malfunctioning. If you have cleaned the brush and replaced the belt but the brush still won’t spin, the motor may need to be replaced.
  • Lastly, it’s important to note that some Roomba models have a brush cleaning indicator that notifies you when the brush needs to be cleaned. If this indicator is on, it means that the brush is too dirty and needs to be cleaned before it can spin properly.

If your Roomba’s brush is not spinning, it could be due to a clogged brush, a loose or damaged belt, a malfunctioning motor, or a brush cleaning indicator that needs to be reset.
