For anyone who is interested the 11" Autobrush complete with angle joint and all connectors to pole hose is 478g. And for those of you familiar with the old style 15" Autobrush that switched from left to right, the weight of that one complete is 732g, so quite a considerable difference. I also weighed a 10" oval shaped Vikan with alloy goose neck and it came in at 766g.
