I no this has been asked before
I'm thinking of changing my Brush to a sill Medium Bristle with fan jets.
Do you think this is a good idea.
I'm currently using four Pencil jets dual trim Brush but I'm sometimes not getting the results I want.
Any thoughts
Not getting results onwhat type of windows Steve ?
We use mostly 4 pencil jets too on all window types .
And just a thought - what do you run your pump at half flow full flow ?
Outs are 7 lpm on close to full for better quicker rinsing off .
A lot of ours are 2 monthly plus to yearly so very like first cleans . Builders can be a nightmare trapped dust and dirt . For speed flow is your friend . And the obvious - hammer the frames and windows then go back over just the glass and frame missing the top frame . Try that for a few weeks with pump on full so 99 or what ever the top setting is . Don’t forget that your hose 1/2 inch/ microbore or mini bore all restrict the flow so you won’t get 5 lpm at the jet . Loads talk about saving water I don’t see point in scrubbing harder rinsing for longer etc .
