The Roborock Qrevo 5AE and the Roborock Qrevo S5V are essentially the same model, only sold under different names in different regions/sales channels. Functionally and technically there are no clearly defined differences between the two variants, they share the same platform, features and cleaning technology.

According to the manufacturer, it is 12,000 Pa.

Yes, you can add detergent, preferably the original Roborock floor cleaning solution for robotic vacuum cleaners with mopping function. For models with a base station like this one, it is added to the fresh water tank of the station to prevent damage. Other agents are possible, but Roborock only recommends their own, as third party products can cause corrosion. The in-house data does not contain any explicit information on this.

Unfortunately, we don't have any spare parts for the Roborock Qrevo 5AE on sale.
