As already mentioned, more force may be needed. Many teams utilze pneumatics to raise/lower the "H" drive wheels, thus giving it more down force. Also, the full raising of the wheels eliminates drag and wear. Omni's do have drag, especially when at an angle not inlign with the rollers. Also the omni rollers wear quite a bit on the carpet. We had a few omnis replaced last year due to "Flat spotting" a few rollers . It's just the nature of the beast.
