OK so I've to clean internal atrium about 45/50 ft, just wondering if anyone has used a trolley on low setting with guttersucker mopping up water. I know ionic had a internal machine similar.
Any advice welcome

Yes i have cleaned an atrium this way. Contoller on wfp set on low about 10 but turn water on and off so use bare minimum of water. There are big panels so scrub lower panels with water turned off as they get soaked from rinsing off upper ones. I use line tap on hose which I hold do can turn on and off quickly.

I don't use gutter vac for exces water just use dust sheets and old curtains. Soaks up pretty well. I sometimes trad lower panels to use less water.

Atrium floor is just standard patio slabs .
