Hello yes it is a CH plug and 1 pair of rollers. But can be bought additionally. There are different ones. I am very satisfied with the device

2 rolls, so one pair. Go well in the washing machine. The appliance is OK as a supplement but not a cleaning monster. Quite ok for moping. Charging time very long.

I am also very satisfied with the appliance. It is easy to use and clean.

Two castors are included and the plug is more of an adapter that fits into the Swiss socket.
