From what I see it gets sucked up into a bag. I just wondered I'd it would be a good alternative to bagging then burning or flushed down the manhole as I have rather a lot of poo to pick up!
Three years ago someone at work used the Henry to clean up vomit. Have you ever tried to clean the inside of one of those hoses? Trust me, it's not easy. Even now every time the damn thing's switched on you can smell vomit. I certainly wouldn't want to try cleaning the pipework after clearing up poo with a vacuum.
