To empty a bagless vacuum cleaner without mess

[A]:
To prevent a mess when emptying a bagless vacuum cleaner, remove the barrel from the cleaner using the deploy button, take a big bin liner and wrap it over the bottom of the chamber and half-way up the chamber itself. Press the chamber open button and gently tap and shake the chamber so all the dirt falls into the bag. If some of it stays inside, use chopsticks or a wooden spoon to dislodge it into the bag. Replace the chamber and tie the bag off.
