Question about Roborock S5 Max

No, this is not recommended by the manufacturer, because these agents could damage the electric pump in the device. I would also only use decalcified water. If Roborock, I would recommend buying the Roborock S6 MaxV, it costs a little more, but has the advantage that it can do 3D navigation and can therefore also recognise and avoid objects. The wiping function is identical to the S5 Max.
