If you are planning on picking up large debris, you should look for a vac with a 2.5″ diameter hose. If you try to pick up large debris with a small diameter hose, the debris will clog the hose and the vac will lose suction.
Friction pushes against the flow, resulting in pressure loss as the pipe length increases. Pipe length also factors in fittings, which increase the “length” input for the equation. Velocity of fluid (v): As flow velocity increases, pressure loss also increases and efficiency decreases.

I just changed the bag and filters. The machine runs, seems normal, but there is no suction. There is no blockage of the hose, as indicated by the fact that that little viewer window above where the hose connects to the unit is not showing the red portion that it shows when there is something blocking the hose (god, this is hard to describe!).
If I disconnect the hose and put my hand over the hole, I feel some suction. But
.Low suction, poor pickup, or no suction may be due to a clog in the vacuum cleaner. If you notice a change in the sound of the motor or a reduction in the spinning action in the Dirt Container, check for clogs. Unplug cleaner from electrical outlet. Empty Dirt Container. Check Upper Tank and Louvers for build up or clogs. Check to make sure Louvers are installed correctly. To unlock the Louvers, grasp the rim and turn toward the left. Pull straight down to remove. If the Louvers are missing or not locked into place, check and clear the tube in the center of the Dirt Container. Remove the Twist ‘n Snap Hose from the vacuum by turning to the left. Check the Suction Inlet, Hose and Hose Wand for clogs. Remove any clogs from the hose using a long, narrow object. Check the Foot Hose for clogs. If needed, remove the screw attaching the Hose Wand Base to the vacuum. Straighten the Foot Hose and unclog with a long, narrow object. If the clog persists, then check the Rotating Floor Brush the Air Passageway for obstructions.
