I have one of these. It works when it feels like it. Everything must be just right. The orange hoses kink very easily and that causes issues so a better suction hose would help. Be prepared to get wet and full of sand as in most cases when blasting into corners it comes right back at you.
efficient sandblasting requires high CFM not PSI. Plus with that short of the nozzle the send won't accelerate to max velocity that would be supported by the 1500+ PSI that the pressure washer is capable of. Average "small" sand blaster runs at around 11 cfm at 90 psi. 1 cfm is about 7 gpm ; so to have "equivalent" power at say 2000 psi you need 3.5gpm pressure washer and then 95% of it would be wasted due to short nozzle So you really need like 70gpm 2000 psi pressure washer to equate a small/medium size blasting cabinet.
I'm researching these with the intention to purchase one, I noticed this other one has 2 tubes going into the sand which may help the air flow into the bucket end, plus the sand type. Link to the video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DVe0vBAYubM.html
