So useful!
Just spending the week cleaning the black mold/algae from our driveway.
Ive bought a few Hyundai power washers. Unfortunately it's practically impossible to replace the Hose if it cracks. If you go the buying route, get one that you can replace the power hose.
I bought a few on Lazada, cheaper than any shop but impossible to cover the 1 year warranty.
I'm using the Storm, works great. Look around probably cheaper options.
