We recommend to perform a detailed service check and clean-up of the mower once a month.
remove the unit from the station,
check all moving parts including the blade status,
remove any external object,
use a leaf blower to clean the clippings,
if necessary loosen the clippings with a brush,
turn-off the unit, then remove and disconnect the shell,
blow the clippings and dust,
detach all accumulations of clippings,
clean the lift sensors,
reinstall and reconnect the shell.

Enjoy your well-maintained robot.
