Comparing the suction of the Kirby with the hose - to a canister - the Kirby is much louder with much less suction. My best friend, and FORMER VCCC member - Clay Floyd - used to tell a story about the man he worked for at the Rainbow office. His boss was shown the newest Kirby, and they put the water lift gauge on it. It pulled 35. Clay's boss said "If my Rainbow pulled 35 on the gauge, I'd take it apart to see what was wrong with it".
