3. Using Your Omni C28
• All UI images shown in this section are for illustration only, and they may be subject to change due to
software updates. Please refer to the actual app interface for the most accurate information.
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 eective if dirty or used on carpeted / reflective floors. Place physical barriers or set a “No-Go” zone to block
o areas where RoboVac may fall.
3.2 Mapping
This feature is designed to help your RoboVac eciently 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 eciency 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 O 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.
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.

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.
3.5 Select a Cleaning Mode
You can start / pause cleaning or select the desired cleaning mode via the eufy app.
In each cleaning mode, you can further customize the modes, cleaning intensity, water level, suction level, and
other settings.

3.5.1 House Cleaning Mode
Tap "Start" in the eufy app to enable House Cleaning mode.
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.
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.

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.
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.
5. Using RoboVac with Alexa, Siri, or Google Assistant Compatible
Devices
With Alexa, Siri, and Google Assistant compatibility, your RoboVac is just a voice command away from cleaning
every corner of your house.
Before you start, make sure:
• RoboVac is attached to the Omni Station to ensure there is enough power.

Once the child safety lock is enabled, all buttons will be locked to prevent children from damaging the device or
accidentally getting hurt.
• Network configuration and factory reset are not aected by the child safety lock.

67/UDP:
Port used by the DHCP server to receive configuration requests from clients.
68/UDP:
Port used by the DHCP client to receive configuration information returned by the server (such as IP address,
subnet mask, gateway, etc.).
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.
