Roborock Qrevo Plus vs Qrevo Ultra: The Ultra is better, but the $400 premium is a convenience tax

Regarding the Roborock: The Ultra adds automatic dustbin emptying and self-cleaning mop washing, so you never touch dirt or wash pads for weeks. The Plus uses the same navigation, suction, and mopping mechanism but requires manual dustbin emptying and occasional mop pad cleaning. If you’re okay with five minutes of maintenance per week, the Plus delivers the same cleaning performance for $400–$600 less.
