So they electrostatically attract dust the same way that a record attracts dust and a rubbed balloon can pick up flour very visibly in a demo. When the astronauts re-entered capsule, they brought sharp-edge gritty dust with them.

The legs are spindly because of moon gravity, they only have to support 1/4 Earth weight.
