To ask the obvious question…did you check to make sure that the lid on the trash can is air tight? If you are losing suction without a filter, make sure you just don’t have air leaks. Also, if you are using one of those lids that has the right angle nozzles to create the cyclone effect in the can, those right angles add even more resistance. I think you would get better separation with a nozzle that injects the airstream from the side instead for straight down from the top with a right angle. Finally, a Thein baffle might help reduce how much dust gets swept past the separator by keeping the turbulent air away from the collected dust. Easy to make and might improve how much dust actually ends up in the can versus blown outside.
