This is a 2015 thread that basically states Festool M and L are same machine with same filter but M has added suction drop-off detection alarm - while auto-clean is optional and not part of the M standard.  Is this still correct?

Yes, still correct.

But I'm sure I also read somewhere that my 2019 manufactured CTL 26 e will bleat if the pressure drops - so isn't that basically giving what you'd pay extra for an M to supply?

Not that I'm aware of. In order to decide there is a blockage or bag full related to airflow, you'd need to be able to select the hose size as you can on an M class extractor, and that's not possible on the CTL 26 E.

Oh wow - so that's why there are so many M Class stickers being advertised on eBay!

Thanks,

Run the vac, block off the flow for a few seconds and if it beeps its got it, if not then it hasn't.
Pretty sure CTLs don't but knock yerself out, give it a bash and see.

Looking on the net it seems that its only very recent Midis that can be M class so the people after the stickers are trying to pull a fast one.

Too many of those wallys and eventually the whole standard gets changed to an even more stringent one.

If that looks like I'm being tough on them? Tough, thems the rules.
