DIAGNOSIS The bin is overfilled or a large object is jammed in the opening, preventing the mechanism from sliding open.
FIX Hold the vacuum over a trash can. Don’t just press—squeeze the red bin release latch and simultaneously *pull down* on the clear bin with your other hand. Use firm, even pressure. The mechanism is stiff by design.
IF THAT DIDN’T WORK A chunk of debris is likely physically blocking the slide. You may need to manually pry the bin open with a blunt tool (like a butter knife) at the seam while holding the release latch. Be prepared for a mess.
HEADS UP Never try to empty the bin by banging it on the side of a trash can—this can crack the plastic cyclone assembly inside, which is a costly repair.
