It has a heavy duty plastic attachment and it feels solid enough.It works great,it has a valve on the top to adjust the air/water/foam mix which makes great foam that clings to your car.They sell metal attachments for the bosch for £6.99 but the plastic one is fine.I looked at the more expensive lances and Im glad I went for the one I did,it works just the same and is a good £20 to £30 quid cheaper.
