The bleed valve is just adding more bulk. Something that was already in the assortment to buy if you'd like it... (I did by accident, costed me return shipping [mad]), that nobody asked for... now standard. Added size, weight and cost.
I'm happy I bought my Midi when I did, because now it includes that stupid thing.
With the sanders, PS, OF... the hose end is already often the bottleneck in corners. And Festool made it worse... at nobody's request, by adding the dumbass bleed valve.
And ofc they immediately discontinued the older one without the valve. F**ng bullshit.
Never ever have I felt the need for a hose with a bleed valve.
