Measure the inner diameter of your nozzle with a ruler, a tape measure or a meter. If it is broken and you cannot measure it, then measure the outer diameter of the tube, from the side that goes into the nozzle.
If you measure 3.2cm (32mm) then buy a nozzle with a code that starts with 32, eg 32265
If you measure 3.5cm (35mm) then buy a nozzle with a code that starts with 35, eg 35295
You can choose from the filters whether your nozzle has wheels or not.
