Rescue from the vacuum cleaner

I have identified the top reason of LEGO pieces disappearing in our household: the vacuum cleaner. On suspicion I reluctantly decided to explore the bag's content (Miele HyClean N/G) after it was full and here is what I extracted: Three LEGO pieces, three puzzle pieces, a screw driver head, a pinwall pin, a Mastermind pin and some yet to identify metal item.
