Turn ON Station and WINBOT
Press and hold the Power Button on the Station for 2 seconds or more to turn on Station and WINBOT.
Before use, make sure Station has sufficient battery. If Station battery is low, refer to the Charging section. Under room temperature, charging time is approximately 3 hours.

Properly Place the Station
Place the Station next to the window you want to clean.
Notes:

1. Try to place the Station as close to the window as possible to prevent people or animals from being tripped over by the Compound Cable.
2. If you need to clean larger floor-to-ceiling windows, ensure that you place the Station on the ground near the window opening because the Compound Cable may not be long enough.
3. Place WINBOT Station on a flat surface to facilitate the attachment of the Bottom Suction Cup.
4. Do not place the Station on uneven surfaces, such as carpets, floors with gaps, as it may result in loose attachment of the Bottom Suction Cup.

• The effective length of the Compound Cable is 5.5 m. Suitable for windows with a maximum size of 4 meters in width and 2.5 meters in height.
• Bottom Suction Cup can only attach on flat, smooth, and seamless surfaces, such as smooth and seamless flooring, tiles, and marble.

Take WINBOT Out
Open the Front Cover, hold WINBOT handle, and lift WAINBOT upward. You can extend the Compound Cable as needed.

Take Out Accessories
Gently press the Back Cover and take out Mopping Pad and the bottle.

Fill up the Reservior
It is recommended to add the tap water into the reservior. The maximum volume of the Reservoir is about 60 ml, and it can spray for about 60 minutes when the Reservoir is full.

Note:
Do not add too much tap water to overflow the Reservoir.
Do not add purified water nor filtered water.

Install Mopping Pad

Wet the Mopping Pad

Tie the Safety Tether
Properly tie the safety tether to a stable object that cannot be easily moved (e.g. table leg, chair leg, bed leg, sofa leg, curtain rod, stair handrail, etc.), and lock the carabiner as shown below.
Hang the rope and wrap it around the surpport.
Open the carabiner, then attach it to the rope on the other side.
