Nilfisk Extreme X300 Vacuum Cleaner 32mm On-board Dust Brush Nozzle
This was formerly the triangular shaped soft dusting brush that fitted under the accessory cover on The Nilfisk Extreme X100 X150 X200 X210 and X300 vacuum cleaner. It also was for the Nilfisk Power P40 and P20 Allergyvac and the Nilfisk SELECT. The part number was 147-0300-500
As you can see now, it is totally different.
