Bear in mind that the outer red lever is pushed DOWN and AWAY from the body to release the bin, THEN when you can see the little red tab, push that toward the clear bin to release (only moves inwards about 1mm or so). If the big outer lever will NOT move, and the bin is still stuck, see below:
FYI: just found a solution that may work for some. On the V11 (maybe V10 and 8 too). When the bin/cylinder is carefully removed (gently pull and rock the bin off the main body until you can see the red release tab, press that and remove the bin), clean the mesh part on the main body with a damp cloth to remove dust particles, wipe the red seal on the bin, and the black rubber seal on the body. When dry, apply a MINUTE amount ( a smear) of silicone grease around both seals. DO NOT let any get onto the plastic parts, otherwise it will attract dust. After I had done this, my v11 undoes the bin just fine now. Many auto spare shops sell silicone grease, and it is useful for many other items around the home and garage too.
