(Its blown up a bit, the hose is less than 2" diameter)
I use the vacuum for emptying hops from my boiler. As its used after brewing (not during or before) I only cleaned it by sucking through some fresh water. But even so, having seen this I don't want that coming anywhere near my brewing kit - I bumped the end whilst taking a photo and green/blue dust rose gently out, dispersing in the wind.. Eew
