This article and the photos helped me open up my LG Hom-Bot 2.0 in order to disconnect the speaker (which was always beeping in the middle of the night).

First I removed the red thin plastic cover: no screws, just plastic clip-on

Discconnected the connector of the "keypad".

Now 5 screws are visible below.

Then I removed the thin black outer plastic cover: no screws, just plastic clip-on

Now a 6th screw is visible below.

Removed 6 screws.

Now I had access to the speaker connector.
There is just 1 speaker and the connector is easy to see and disconnect.

Now I have a silent LG Hom-Bot 2.0, no more disturbing nightly beeping.

Here are all the photos (in random order).
