Roborock S8+/S8 vs Roborock S8 Pro Ultra

The Roborock S8 Pro Ultra is a better vacuum than the Roborock S8+/S8. The S8 Pro Ultra has a more advanced multifunction dock that empties its dustbin, washes and dries its mop pad, and refills its water tank. The S8 Pro Ultra also has a lifting brush head that can keep the brushes from being stained as it mops. The Pro Ultra has a fast-charging feature, too, leading to less downtime between cleaning sessions. However, it's worth noting that the regular S8's VibraRise mopping system is a little better at dealing with stains compared to the S8 Pro Ultra's VibraRise 2.0 system.
