Question about Dyson Pure Cool Me

Mine always squeaks the first 3 times back and forth, then no more... Unfortunately, I don't have a solution.

When we bought it last year, it didn't squeak. But when we used it this summer (after the winter break), it unfortunately squeaked too. 🤷♀️ Despite taking it apart and cleaning it, we couldn't find a solution.

Same thing with me with a Dyson floor fan.... Maybe plastic or something

How long have you had the device? How often do you use it? I would possibly oil it a little...
