Yep, just the extreme.
Didnt like the sill brush.
If a con roof is only a bit grubby, i use the extreme.
If its reasonably dirty, i use a s/lite mono,
If its mingin', i use a modified superlite, with the outer, longer bristles, cut down so the're level with the inner bristles for a really hard scrub.
Ive used the last brush to remove ingrained lichen.
Also, all these are cleaned using hot water & no pretreatment
