Squeaking can be a wheel or brush issue rather than a sign of poor suction. Locate the sound before buying parts or applying a lubricant that can attract dirt.

Start with these checks
- Clean the accessible front caster and inspect it for wrapped hair.
- Check whether the sound remains with a freshly cleaned, correctly fitted main brush.
- Test on a second clean hard-floor area and note whether turning changes the noise.
What this looks like at home
A squeak during turns but not straight travel makes the caster area worth inspecting first.
Test the machine and the obstacle separately
| Check | What matters |
|---|---|
| One location only | Examine the shape, surface and escape route. |
| Every location | Check accessible wheels, bumper and brush assembly. |
| After maintenance | Recheck the fitted parts before changing the map. |
A mistake to avoid
Household oils and spray lubricants can contaminate floors and parts; use only manufacturer-approved servicing.
Buy a part only after identifying the cause
Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you
Tell support whether the sound happens during turns, straight travel or both. That simple distinction is more informative than a general description of the robot as noisy and can prevent unnecessary suction-setting changes.
