The advantage of the midi or mini vs the CT 22 is size and it comes with a hose garage top. I have the 22 and as someone else mentioned, its not heavy nor bulky. There is a bit of weight when the bag gets close to full but its still reasonable. I usually look at these situations as what might you need in the future. I opted for the 22 for the extra capacity, Hepa and more suction power. I knew I would only buy one vac and figured the extra cost was worth it.
The vac with the TS is great but I really love it for sanding.
