Dreame L40 Ultra squeaks when turning

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

I used some silicone lubricant on the front wheel and it solved the issue.

You need to pop out that little wheel that changes direction - run it under the tap to clean it, dry it off and pop it back in. The squeaking will stop

I sprayed the wheels with no success but changing the main roller brush did the trick.

Mine as well. Is the MANUFACTERER reading our problem page. Perhaps they could offer a solution???

I've got the l10 it does the same thing!!! Drives me crazy!!!

Mine started too

Mine did that and a sprayed the wheel with liquid wrench and it stopped immediately. In about a month, the squeak was back and I sprayed again and squeak was gone.

When my Dreame was squeaking, I opened up the area that all the yuckies are vacuumed into. There was a piece of wood about 1/2 inch wide and about 3” long. It was stuck and I had to pry it out. There was a lot of hair also around it. It did stop whistling after that.

Mine just started doing this too. It's very annoying.  Is anybody from the manufacturer read these forms? Can they make suggestion on how to fix it?

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.
