Hi Benji
i also have a trolley sysem and i do the downstairs by hand what i do is all of the upstairs first and by trhe time i have got back to the front to do the bottoms have usually stopped dripping.
i do the downstairs tradional just as a compromise for my csm,s plus i can only carry 300l of water and usually by the end of the day i will get very low on water.
i also have csm,s that will only let me clean with the wfp they find it a better clean in that they stay cleaner for longer , also if at the end of the day i have water left i will clean the houses up/down with the wfp some of my csm don,t mind some are a bit funny i just make sure i do the funny ones wfp up trad down it,s no big problem and it,s still a little quicker but a hell of a lot safer
darren......
