The Omni S Plus is the Omni S Pro without the E-Pad S touchscreen: the same table-end clamp mount, automatic recycling of 250 balls, 2-15 m/s, 30-90 balls a minute and full-table oscillation, controlled from the Bluetooth app alone. It comes in white instead of black, has 198 pre-programmed drills instead of 522 and tops out at 80 r/s of spin in 11 levels instead of 100 r/s in 23, which is what brings the price down. See the Pongbot comparison chart.
