There is some magnet or sensor in the filter and if they is some small misalignment it refuses to work, I’ve had to replace the filters on at least 2 Dysons because of this ‘feature’. I’m not sure what it achieves… other than ensuring you need to replace parts after you’ve cleaned it a few times and the fit gets sloppy.
This is the only justifiable way to acquire a Dyson in 2025. I saved a friends vacuum from the bin by dismantling it and pulling a clog out of a pipe, so many I’m sure get thrown away because people just don’t maintain them and assume they are broken.
