Luckily the electronics area is above the sealed vacuum container area - the lid is two layers thick with the bottom of the black one being air tight with rubber gaskets and all - so no air leak at all - and even better no dust or dirt. I will post a better photo - the hose looking connection is misleading in my photos - once the two halves (top and bottom sections) of the top lid are put back together that hose connection mates up with another one and seals. Trust me.Looking at the third photo down and the black vacuum orifice and then comparing it to the slotted cuts surrounding the battery . . . . surely you're loosing ~ 50 % of your suck capability with that air leak fallacy.
