I don’t know why I have not tried this before but I made a small hand held wfp brush with a fan jet yesterday.
I have done some screened in porches and even really low walk out basement windows this would come in handy for. I am pretty sure one like it is available, however I decided to try one out on my own…
I pulled out some middle bristles, drilled through for the same spot. Then drilled a bigger hole from the back about 3/4 through. I tapped in the fan jet, attached the hose, then filled that space with a marine grade epoxy I found that is really good to keep the hose fastened.
The Vikan hand held brush that wcr now carries is a great little brush for screens, windows with bars and easy to each windows for 23 dollars. It has at least 6 flow through holes in the brush so it puts out plenty of water. It has become one of my favorite tools for cleaning those really dirty screen that have dust caked on.
