... a blower port ...
Strongly, strongly against a blower port. A blower port means the vac is spewing all kinds of dust around itself by the wind it creates.
This is not a feature I want to se in a shop-use vac like the 26/36/48 series. If someone needs a blower port of off-shop use, there are the Mini/Midi series for that.
Secondly, a blower port does not allow a "muffed" air out, one of the things making the bigger vac series so quiet.
Onto what would be nice to see:
- Do
not change the bottom mechanical parts. So the same filters, the same bags and the same other accessories work. IMO there is nothing to really improve there.
- Re-introduce the non-garage model option as a "cut-down/basic-offer" design for shop use. Like a "big CT15" of sorts. Or use the CT22/33 approach where the garage was optional.
- design the garage so it can be pulled by it - a proper handle on the front (and back ?) would be ideal
Rest was already said.
