Miele S140 Operating Instructions Manual page 21

There is a non-skid rubber bumper on
the vacuum handle. This allows the
vacuum to be leaned upright against a
wall if desired.
Before leaving the vacuum make
sure it is turned off and leaning
against a wall at a safe angle.
To protect the bristle rings on the rug
and floor tool, we suggest hanging the
vacuum on a wall hook by using the
hole located on the bottom of the
handle.
