Pressure Washer Karcher HD Compatible Sandblasting Attachment Kit

This looks a nice piece of kit out of the box. But on first try the nozzle is just pulsating a not very fine jet, and sand is hardly lifting out the bag. Hopefully something easy to remedy.... waiting on feedback from seller

For the money I was willing to give it a try....but it's great! It certainly surprised me and it does do everything it claims to do. Only thing I'd advise is a full face protective mask as the bits rebound and hit you. Other than that...brilliant.

Sadly does not work with all karcher HD systems - I have the HD5/11 and the pressure washer continually pulses - an indication that the nozzle is not correctly balanced to this system.

Despite the sand blast attachment having a max rated pressure of 160 bar, my Karcher K4 having a max output pressure of only 130 bar, this attachment is a waste of money as the pressure washer just continually pulses....Don't waste your money
