2.1 Install the Omni Station

1. Remove the protective film on the Omni Station.

  • When peeling off the sticker on the cleaning tray, press down on the cleaning tray to prevent it from coming loose.

2. Install the detachable base by pressing down firmly on both sides.

  • Make sure the detachable base is seamlessly connected to the Omni Station; otherwise, the robot will fail to return to the Omni Station smoothly.

3. Place the Omni Station in a location that has strong Wi-Fi signal and the robot can easily access. It is recommended to place it against a wall and on a hard, level surface. Then, plug the station into a wall outlet. When the Omni Station connects to AC power, the LED indicator will light up in white.

  • The recommended clearance on the illustration is a suggested value based on testing, to ensure the robot operates optimally, returns to the station for charging, and cleans the designated area effectively. You may adjust the clearance distance as necessary to suit the actual working environment of the robot.
  • Do not place the station on carpets.
  • Always keep the station plugged in to ensure the infrared connection between the robot and the station is successful, otherwise the robot will not automatically return to it.

4. Take out the clean water tank. Add clean water until it reaches the MAX water line.

  • Please do not add hot water into the tank to avoid shortening its service life.
  • Please do not add non-eufy cleaning solutions or homemade cleaning liquids to avoid damaging the machine.

5. Reinstall the clean water tank. Ensure that both the clean water tank and dirty water tank are securely locked; otherwise, the station will not operate normally during subsequent use.

3.1 Important Tips Before Use

A. Remove power cords and small objects from the floor that may entangle RoboVac. B. Fold tasseled edges of rugs underneath to prevent tangling RoboVac. Avoid cleaning high-pile rugs or rugs thicker than 0.71 in / 18 mm as they may cause RoboVac to malfunction. C. It is strongly recommended to place physical barriers in front of fireplaces and certain areas (i.e. air vents) that may cause damage to RoboVac if entered. D. Avoid vacuuming large amounts of water as it will potentially damage the device. E. RoboVac may climb on top of objects less than 0.79 in / 20 mm in height. Remove these objects if possible. F. Anti-drop sensors will prevent RoboVac from tumbling down stairs and steep drops in most cases. Sensors are less effective if dirty or used on carpeted / reflective floors. Place physical barriers or set a “No-Go” zone to block off areas where RoboVac may fall.

Section 10

3.2 Mapping

This feature is designed to help your RoboVac efficiently learn the layout of your home, ensuring thorough and systematic cleaning. By creating a detailed floor plan, your RoboVac can navigate and clean with precision.

To maximize the efficiency and accuracy of the mapping process, please follow these steps:

  • Open All Doors: Ensure all doors within the cleaning area are open. This allows the robot to access and map each room seamlessly.
  • Block Off Restricted Areas: If there are specific zones you don't want the robot to enter, use physical barriers to block these areas. This can enhance mapping accuracy and prevent the robot from entering unwanted spaces. After the mapping is completed, you can remove physical barriers, and set up restricted areas to prevent the robot from entering those areas.
  • Remove Obstacles: Clear any objects, such as toys, cables, or small furniture, that might obstruct path or become entangled in its brushes. This helps RoboVac move freely and map the area without interruptions.
  • Do Not Move the Base Station: Once the floor plan is created, avoid relocating the base station. RoboVac relies on the base station as a reference point for navigation and mapping. Moving it may disrupt the accuracy of the floor plan.

To start the mapping process, tap "Start" in the app.

11 / 39
Section 11

3.3 Set Up No-Go Zone and No-Mop Zone

With the eufy app, you can set up a “No-Go Zone” or “No-Mop Zone” as a restricted area. This eliminates the need to use physical barriers, including boundary strips. This feature is only designed for dividing the cleaning zones, not for isolating hazardous areas.

12 / 39
Section 12

3.4 Schedule Cleaning

With the eufy app, you can schedule RoboVac to start cleaning at a particular time.

  • You can set the time and customize cleaning schedules from Sunday to Saturday on the eufy app. This function is only available on the app.
  • During the Do Not Disturb period, RoboVac will remain silent, with automatic dust collection and voice notifications disabled.

After startup, RoboVac moves from the Omni Station and automatically determines its cleaning route. When cleaning is finished, RoboVac automatically returns to the Omni Station.

15 / 39
Section 15

3.5.2 Room Cleaning Mode

In this mode, your house is automatically divided into several rooms for cleaning in the eufy app. You can also customize your room settings in the app. RoboVac will clean the selected rooms only and return to the Omni Station after cleaning.

  • Enable Room Cleaning mode only after RoboVac has created the map.
  • It is recommended that RoboVac moves from the Omni Station to start room cleaning.
16 / 39
Section 16

3.5.3 Zone Cleaning Mode

In this mode, you can set up a cleaning zone and customize its size in the eufy app, RoboVac will clean the selected zone only.

17 / 39
Section 17

4. Using the Mopping System

1. Start cleaning. RoboVac will automatically vacuum and mop. During mopping, you can choose between three water levels via the eufy app. 2. To prevent the development of odors in the roller mop, be sure to activate the drying function after each mopping task. We strongly recommend setting the drying mode to "Standard Drying" every time to ensure optimal drying results and reduce unpleasant smells. 3. Regularly empty and clean the dirty water tank to prevent mildew or unpleasant smells. For instructions on how to clean the dirty water tank, refer to the “Cleaning and Maintenance” section in this User Guide.

67/UDP:

Port used by the DHCP server to receive configuration requests from clients.

38 / 39
Section 38

68/UDP:

Port used by the DHCP client to receive configuration information returned by the server (such as IP address, subnet mask, gateway, etc.).

39 / 39
Section 39

Function:

DHCP uses these two ports to automatically assign IP addresses to network devices, simplifying network management. For example, when a device connects to a network, it sends a broadcast request through port 67, and the server responds and assigns the IP configuration.

Ports 67 and 68 are required for computer network configuration and Internet access and are commonly used in normal business operations.
