Question about Rainbow E series Canister Wet/Dry Vacuum
With years of use, you will collect a layer of "micro dust" on the impeller (the fan part) which reduces the efficiency. A toothbrush and some mild cleaner with gently scrubbing will restore it's power.
The impeller is that parts that spins that you can see when you take the top off to fill the water tank.
Hope this is the answer that you need!

Is the water seal in place or missing? Another cause would be a bad motor, running at a slower speed will mean low suction. If it is a motor, then you would have to replace it. Is the suction low at machine without the hose, if it is ok then may be a clog in the hose.
