* If WINBOT is powered on but the fan is not working, WINBOT will shut down after 10 minutes of inactivity. To restart, press and hold the Power button. - Fill up the Water Tank
It is recommended to use it with the ECOVACS WINBOT Cleaning Solution. The maximum volume of the Water Tank is about 60 ml, and a full tank can sustain spraying for about 60 minutes. In Fast Cleaning mode, a full tank can cover an area of approximately 30 ㎡ .- Use ECOVACS WINBOT Cleaning Solution for better cleaning performance.
* If the ECOVACS WINBOT Cleaning Solution is used up, use tap water as a temporary substitute. - To avoid product damage, do not use any cleaning solution other than the dedicated ECOVACS WINBOT Cleaning Solution. Do not use distilled water or filtered water.

Attach the Wiping Pad to the velcro at the bottom of WINBOT, then press it firmly to ensure it sticks securely.
Note: Remove all protective materials, including but not limited to the EPE protective strips around WINBOT and the protective film on its side.
- Wet the Wiping Pad
Ready for Cleaning
- Properly Place the Station
Place the Station next to the window you want to clean.
Notes:- Try to place the Station as close to the window as possible to prevent people or animals from tripping over the Compound Cable.
- For cleaning larger floor-to-ceiling windows, place the Station on the ground near the window opening in case the Compound Cable is not long enough.
* The effective length of the Compound Cable is 5.5m, suitable for a maximum window size of 4m in width and 2.5m in height. - Place the Station on a flat and seamless ground surface.

* Do not place the Station on desks or shelves. - Do not place the Station on uneven surfaces, such as carpets, floors with gaps, as it may result in loose attachment of the Suction Cup.
* Suction Cup can only attach to flat, smooth, and seamless surfaces, such as smooth and seamless flooring, tiles, and marble.
- Start Cleaning
Make sure Station and WINBOT are turned on.- Press and hold the START button on WINBOT for 2 seconds to start the fan.
- Place WINBOT’s bottom close to the glass. WINBOT will automatically attach itself and start cleaning.
Notes:
* Do not place WINBOT too close to the edge of the window. It is recommended to keep a distance of at least 10cm from the edge of the window.
* WINBOT is only suitable for flat surfaces without gaps.
* After the fan is started, do not bring small objects such as hair close to the fan to prevent them from being sucked in and blocking the fan.
* Before cleaning, please observe the area to attach WINBOT for any small particles. If there are any, please remove them or switch to a particle-free area to avoid scratching the glass.
- Swtich Modes
When WINBOT is working, you can switch cleaning modes by pressing the Mode Switching button on the Station. After switching the modes, WINBOT will start the new cleaning mode immediately.
Note:
Press Mode Switching button to switch between Thorough Cleaning, Fast Cleaning, and Edge Cleaning in sequence. To learn and use more modes, refer to the ECOVACS HOME App.
Select Cleaning Modes
Select the proper cleaning modes via buttons on the Station. If no mode is selected, WINBOT follows the last remembered mode by default.
Suggested Modes:- For moderately dirty interior windows, use Fast Cleaning.
- For heavily soiled exterior windows, use Thorough Cleaning.
- For detailed information on cleaning modes, please refer to the app.
* Edge Cleaning is not remembered. Thorough Cleaning is the default cleaning mode.
- Pause Operation and Move Station
- Pause
Short-press the Power button on the Station to pause WINBOT’s current work. Short-press the Power button on the Station again to have WINBOT resume and continue the unfinished cleaning task. - Move the Station:
During cleaning, if you need to relocate the station, firmly grip the handle of the Station, lift it, and the Station’s Suction Cup will
automatically unlock. If you release the handle and it drops back down, the Station will automatically reattach to the surface and lock.
Note:
Before use, ensure there are no walls or other obstacles such as furniture within a 10 cm radius of the Station. This allows the handle to naturally drop to its lowest point. If the handle is obstructed from fully dropping down, it will reduce the Suction Cup’s ability to attach securely.
- Pause
- Maintenance during Cleaning
For heavily stained glass, wash or replace the Wiping Pad multiple times and clean the four Spherical Sensors in time.
* Clean the Wiping Pad in time and make sure that any small particles on it are completely removed to avoid scratching the glass.

* When storing WINBOT, remove the wet Wiping Pad. Store the Wiping Pad after it is dried to avoid any unpleasant odors.
- Auto Take up the Compound Cable
After placing WINBOT in the container, press
,and the Station will immediately start reeling in the Compound Cable .
* As the reeling-in process nears completion, the reeling-in speed slows until the cable is fully reeled in. This is a normal occurrence.
* During the reeling-in process, the Compound Cable may become twisted. Do not worry and help straighten it. Then press again
to complete the reeling-in process.
- Power Off
Press and hold
on the Station for 2 seconds or more to power WINBOT off. - Unfasten the Safety Rope

- The WINBOT fan cannot operate while charging. Please wait until the charging is complete before using the WINBOT.
- WINBOT’s fan cannot operate while charging. Please use WINBOT after charging is completed.
- If you do not use WINBOT for an extended period, it is recommended to periodically charge the Station to help maintain its battery health.
- If the Station is charging while WINBOT is working, the Station’s charging speed will be significantly slower compared to when WINBOT is idle. At room temperature (10-40℃ ), this results in an estimated charging time of more than 6 hours.
