Dreame L40 Ultra squeaks when turning

Why does my Dreame L40 Ultra keep squeaking when it turns? If anyone knows pls reply. Thanks.

Mine just started doing this too.

Does the small roller squeak if you spin it? Is there any hair or debris in the mail wheel assembly?

I had to grease the very front wheelthe one that turns 360° really well with a dry silicone spray lube called blaster. I do live on the beach, so WD-40 isn’t an option here as it is in most other places is a quick easy lubricant but either one works great.

I’ve only had mine for 3 months but use it daily. It’s know squeaking so loud the in all cleaning modes.  I have cleaned all the wheels & parts but continues.

Which L40 version do you have…Ultra, S, CE, or AE?

I suspect the noise is coming from the TriCut brush. I recently bought the L40 AE and tracked a similar squeak by removing the side brush, mop pads, and TriCut brush, then running short test cleanings. I added each part back one at a time, and the noise only appeared once the TriCut brush was installed.

It seems like friction in the brush’s internal rod. A good test is to swap in the stock rubber brush and see if the noise goes away. After identifying it, I cleaned the TriCut brush (even though it was only a week old). There was some hair wrapped around the ends. I removed the end cap, cleaned it, reinstalled everything, and the noise became much less noticeable.
