Setup
1. Unpacking
Carefully remove all components from the packaging. Remove any protective films or packing materials from the robot and the docking station.
2. Docking Station Placement
Place the docking station on a hard, level surface against a wall. Ensure there is at least 0.5 meters (1.6 feet) of clear space on both sides and 1.5 meters (4.9 feet) in front of the docking station for the robot to navigate freely. Plug the power cord into the docking station and then into a wall outlet.

3. Initial Charging
Place the robot onto the docking station, ensuring the charging contacts align. The robot will automatically begin charging. For the first use, it is recommended to fully charge the robot before its initial cleaning cycle. The battery indicator on the robot or docking station display will show the charging status.
4. Filling Water Tanks
Locate the clean water tank on the docking station (usually marked). Fill it with clean tap water. For optimal hot water mop washing, ensure the tank is adequately filled. The dirty water tank will collect wastewater during the mop washing process.
5. App Connection (Optional but Recommended)
Download the official Redkey app from your smartphone's app store. Follow the in-app instructions to connect your robot vacuum to your home Wi-Fi network. The app allows for advanced features such as scheduling, cleaning mode selection, no-go zones, and real-time monitoring.

- Mop Drying: After washing, the mop pads are dried with hot air to prevent mildew and odors.
- Automatic Mop Lifting: The robot can automatically lift its mop pads when detecting carpets, preventing them from getting wet during vacuuming.

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your Redkey R20.
1. Emptying the Dustbin/Replacing Dust Bag
Thanks to the auto-drain feature, the robot's internal dustbin is emptied into a larger dust bag within the docking station. Check the dust bag indicator on the docking station or app. Replace the dust bag when full.
2. Cleaning the Main Brush and Side Brushes
- Turn the robot over. Remove the main brush cover and then the main brush. Use the cleaning tool to remove hair and debris.
- Carefully pull off the side brushes. Remove any tangled hair or debris. Reattach them securely.
3. Cleaning Mop Pads
The docking station automatically washes and dries the mop pads. However, it is recommended to periodically remove the mop pads and hand wash them thoroughly or machine wash them (if compatible) to ensure deep cleaning. Replace worn-out mop pads as needed.
4. Cleaning Water Tanks
- Clean Water Tank: Rinse regularly to prevent algae or mineral buildup.
- Dirty Water Tank: Empty and rinse after each cleaning cycle to prevent odors and bacterial growth.
5. Cleaning Sensors and Charging Contacts
Wipe all sensors (cliff sensors, wall sensors) and charging contacts on both the robot and the docking station with a clean, dry cloth. Dust and debris can interfere with their functionality.
