Question about Roborock S7

The S7 offers few advantages over the S5 Max. An S7 can be supplemented with an optional vacuum station and has a cleaning function that can lift the cleaning pad onto the carpet. Navigation is also good on both. The S6 MaxV would offer a real advantage in navigation, as it can use the built-in cameras to recognise 3D objects, i.e. it can recognise a scale on the floor as a scale and can also bypass other recognised objects without simply closing the IR the sensors leave.
