The dust bin is a simple clam-shell type case. Open it over the waste-bin to ensure that it has been properly emptied.

Tip: When working on any cleaning device, wear a mask and, if possible, wash the item to avoid allergies and other issues.

Lay the open bin on the work surface. Be careful not to twist the two halves of the shell as you open it as you may have one hinge pin still in place.

The photo shows a bin in two separate halves. My RoboVac had chosen to throw itself down the stairs, losing the one remaining pin (marked in red) and dislodging the previous repaired hinge (which can be seen in the image - circled in Blue.) Amazingly no other damage occurred, these are robust devices.

You will need a single Bamboo kitchen skewer 3mm in diameter. These are easily found (in the UK, at least) at your local supermarket if you don't have some left over from your last marshmallow toasting.
