Dreame Robot Vacuum Making a Loud Noise? Here’s How to Fix It

Step-by-step fix guide | Dreame robot vacuums

Try this first — Take out the dust box and check the filter. Dreame’s manuals say a clogged filter can make the robot louder: clean it, or replace it.

If your Dreame robot vacuum has got noisier while it cleans, these are the checks from Dreame’s manuals.

What This Problem Means

Dreame’s manuals give three causes of extra noise while the robot is working: a clogged dust box filter, a hard object caught in the main brush or dust box, or tangled brushes. They also suggest switching to a quieter suction mode.

Common Symptoms

  • The robot is louder than usual while it cleans
  • The noise is new, or getting worse

Safe Checks You Can Try

1. Clean or replace the filter

Check whether the dust box filter is clogged. Take out the dust box, remove the filter and gently tap it to knock the dirt out: Dreame says not to clean it with a brush, your finger or anything sharp. Rinse the dust box and filter with clean water only, and let them dry completely before refitting them.

2. Remove hard objects

A hard object may be caught in the main brush or the dust box. Check both and remove anything you find.

3. Untangle the brushes

The main brush or the side brush can get tangled. Press the brush guard clips to remove the brush guard, lift out the main brush and remove any tangled hair with a suitable tool. To clean the side brush, unscrew it with a screwdriver, remove the hair and screw it back on. On the D30 Ultra and L10s Ultra Gen 2 the side brush clips on, so just take it off to clean it.

4. Lower the suction

Switch the suction mode to Standard or Quiet in the app.

5. Replace worn parts

Dreame’s maintenance tables say to replace the main brush every 6 to 12 months, and the side brush and dust box filter every 3 to 6 months.

Brush and filter care

Part Clean Replace
Main brush Every 2 weeks Every 6 to 12 months
Side brush Every 2 weeks Every 3 to 6 months
Dust box filter Every 2 weeks Every 3 to 6 months

These intervals are the same in all twelve manuals. Dreame says the real intervals depend on how you use the robot.
