a-the reason for better suction is how air tight the vacuum is. i think g is more airtight that 1205.
b-the hose might be leaking.
to check the hose for leak
1-prepare a water and soap solution [maybe 10 to 1] in a spray bottle.
2-put the hose to the exhaust blower.
3-spray a little of the soap solution on the hose.
4-turn on the vacuum and put your hand at the end of the hose to stop the air from coming out
5-watch for bubbles.
c-the bag. make sure you have a clean bag.
d-air flow is more important than suction to the cleaning power of the vacuum
