eufy RoboVac G+ series models use Gyro plus Path tracking sensor technology to determine the cleaning route by following a Z-shaped path. With the Gyroscope and Accelerometer smart sensors, RoboVac knows the direction and distance of its cleaning path. When the entire floor is cleaned, it will begin cleaning the edges and corners by following the edge of the walls. After the entire cleaning cycle is completed, RoboVac will automatically return to the self-emptying station.
Here are some common scenarios that may affect the cleaning route of the RoboVac, causing it to miss a certain area or clean the same area repeatedly:
- Thick carpets with tassels or wool, or carpets throughout the room.
The G+ series models are designed to work on hard floors and medium-pile carpets with a total thickness that does not exceed 26 mm /1.02 inches. The RoboVac may get stuck when it cleans on thick carpets with tassels or carpets with a total thickness that exceeds 26 mm /1.02 inches.
- RoboVac gets stuck in certain places, such as underneath the furniture, chairs, etc.
- RoboVac is manually moved during its cleaning process.
RoboVac's internal cleaning algorithms will be affected if it is manually moved during its cleaning cycle, which leads to a deviation in creating its cleaning map that results in inaccurate cleaning patterns.
- Path tracking sensor is dirty.
- An extremely dark colored floor/carpet.
RoboVac detects using IR (Infrared Ray) sensors and carpets/floors that are extremely dark will absorb the IR signal, which leads to the RoboVac failing to detect its surrounding environment. This is a common phenomenon of all the RoboVac models designed using IR sensors that are currently on the market.
- Cleans under direct sunlight.
RoboVac's sensors (drop sensors on the bottom and front sensors on the bumper) work with the sensors on the RoboVac. When RoboVac encounters sunlight, it would detect the sunlight as a stair and either backs away or triggers voice alerts.
- Large house.
G+ series models are suitable for houses below 170 square meters (about 1830 square feet), and the farthest zig zag cleaning length in each cleaning direction is 17.5m, and the RoboVac may miss certain areas if the house is larger than the farthest distance the RoboVac can clean in each direction.
If you are encountering these scenarios, please refer to the following solutions to resolve the issue:
- Thick carpets, extremely dark colored floors/carpets, or RoboVac gets stuck in certain places
The G40 Hybrid+ model supports using boundary strips. Please place boundary strips around your carpets/places where the RoboVac usually gets stuck so it will not enter that specific area and affect its cleaning route. As for the G40+ model which does not support using boundary strips, if possible, please use physical objects to block off the area to prevent the RoboVac from entering it.
- Dirty Path tracking sensor
Gently wipe the optical flow sensor on the bottom of the RoboVac with a cotton swab dipped in rubbing alcohol to clean the sensor.
- Under direct sunlight
If the environment house is sunny during the day and the environment affects the normal operation of the RoboVac, it is highly recommended to run it at a different time of the day or when the window blinds are closed. Alternatively, if you do not have any potential drop spots where the RoboVac may fall down in your home, you can disable the drop sensors by covering them with light-colored opaque pieces of paper or tape.
- Large house
It is recommended to order additional self-emptying stations or charging stations if you have a large house. When the RoboVac begins its cleaning cycle, it can cover more areas due to different self-emptying station or charging station locations. Please do not manually move the RoboVac during its cleaning process.
If the issue persists, please email eufy support for further assistance. Make sure to turn on the "Activity Log Upload" function on the settings of the eufy Clean app (https://support.eufylife.com/s/article/What-s-the-Log-Upload-feature-in-the-Eufyhome-App ) and run the RoboVac so we can learn more information from your log.
