I don't know they exact model/type you have, but Greenworks surface cleaners use a standard ¼-inch quick-connect fitting, which most pressure washers share. If yours is electric, note that the 11" model is rated for about 2000–3000 PSI and ~1.2 GPM or higher. Many electric washers sit around 1.3 GPM and lower PSI, so it will spin, just slower—think gentle patio rinse, not driveway paint-stripper.

this looks like light/medium duty which should be ok for most electric PW. Based on previous experiences I would strongly recommend d pre treating with cleaner that kills mold amd mildew bacteria first otherwise it will come back much quicker. This attachment helps produce more even and consistent result compared to straight jet type nozzles as well as speeds up the process considerably as well. For stronger and more aggressive cleaning they make heavier duty ones as well.

I have this and use it with my electric powerwasher. It will last a year probably and does an okay job. Unfortunately my driveway uses exposed aggregate which take a LOT of effort to pressure wash and this doesn't cut it. Much better for smooth concrete like the sidewalk though.

I got one from Walmart for $10 on clearance a few years ago. Looks exactly the same. I still haven't used it, but it says "Electric Pressure Washer" on the attachment. "2000 PSI max"
