I was told that you were supposed to keep them running all day and only use a bypass into the tank when driving between jobs as  stopping the water with a tap or univale will damage the unit.
I wasn't sure so thought I'd ask especially now as it will be getting colder.

I’ve found the opposite, very rarely get many tips but nearly £200 already this year with the bulk of my residential work still to do. Quite a few have been out to tip in cash but still pay for the clean online which has never happened before.

Gardiner’s have just started producing these. I think with the splay they’ll be a great addition. Especially on large windows & deeper recessed windows.

I use the 35cm Xtreme sill brush with 4 x 1.4mm jets for most work these days with pump controller on full blast. Its a great brush for splashing and dashing at this time of year. I can literally chop an hour a day off my work in the winter months!🙂👍

If you used 3mm jets you could turn your pump controller down or use even more water thus speeding your job up even quicker. Makes no sense using smaller jets unless splashing  the kids at water pistol fights in the summer 

I've just bought the normal size dupont supreme and I'm really disappointed with it! Gardiners seem to have increased  the vertical splay to a point that makes it pretty useless! 🤔
I used to use the flocked supreme and this was superb but this dupont one is terrible in comparison! Also, because of the size of the space required to fit jet capsules, there is at least 1" either side of the brush where there is only ONE row of bristles. On a brush which is smaller to begin with, this is a major oversight IMO and it really shows when you are cleaning a velux window and you can see light through the brush- there's two major spaces barely getting touched! This in turn means that even more movement is required to guarantee effective coverage from an already smaller brush! On a plus point, the dupont ultimate is very good but the blue nylon ultimate trumps them all. 🙂👍
