Did 3 decent sized bedrooms,landing and stairs,clean wool mix berber 27 litres in,as I never fill to the top of the bucket,as end up tipping it everywhere.
Got 2 full buckets out and a 1/4 full,and a bit left in tank,new tank gasket has made all the difference,first rooms dry when I left,was only doing the 1 wet pass,then a couple of dry passes
