Installing the Safety System
Product components
If the device is to be used outside or for tall surfaces, the safety system must be
attached to the robot and to the window before use.
PLEASE NOTE: If there is a power cut lasting more than 30 minutes, the device may fall down
(the emergency battery has a battery life of approx. 30 minutes).

EN
Operation
Loop the other end of the safety tether
(2) around the safety suction cup
(3) and tighten.
Before attaching the safety suction cup,
wipe the surface clean and dry.
If ENERGY RWC-1 is used to clean an
inside window surface, press the safety
suction cup firmly on the upper corner of
the inside window surface.
If ENERGY RWC-1 is used to clean an
outside window surface, attach the
safety suction cup firmly to the lower part
of the window for cleaning.
PLEASE NOTE: If the robot’s movement is restricted by the length of the power or adapter
cable, you may use an ENERGY RWC-1 extension cord. Disconnect ends A and B, connect
them to the respective ends of the extension cord and screw them tight.
Using the Extension Cord
