Segway Navimow 6021 robot mower: fails to reach its destination
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On the Navimow H, error 6021 means the mower cannot reach its destination, such as the charging station. Segway points to grassless stretches on the way, obstacles, a station hidden in shade or bushes, a poor positioning signal in narrow passages or a dirty VisionFence.
Safety first
Stop and check this first
- Before putting your hands near the mower to clean the VisionFence or carry it, stop it with STOP, power it off with OK and wear gloves: the blades can cut even when the disc is still.
Safe checks you can perform
- Walk the route to the destination
- Clear obstacles from the path
- Check where the charging station sits
- Clean the VisionFence and review narrow passages

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Email Segway Navimow support
What they doIf 6021 persists after checking the route, obstacles, station and VisionFence, Segway asks you to email its support team at support-navimow@rlm.segway.com.
They must show youwhich stretch of the map or which positioning data they identify as the source of the fault.
In writingtheir recommendations for map changes or station relocation and, if a part is replaced, the reason and the warranty cover.
Map adjustment with support guidance
What they doIf you are unsure which areas to mark as VisionFence-off or which corridor causes the poor signal, ask support to guide you through reconfiguring the map.
They must show youthe excluded zones and the new route on the app map.
In writingwhich areas were set as VisionFence-off and what was changed in the narrow passages.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Walk the route to the destination
- Who:
- you, with the mower stopped.
- How:
- press STOP on the mower and walk the path between where it stopped and where it was going. Look for patches with hardly any grass and for stone paths with grass growing in the joints.
- Result that matters:
- finding grassless stretches the mower cannot get across.
- If you find such stretches:
- set them as VisionFence-off zones in the app, as Segway recommends.
- If the whole way is grassed:
- look for objects blocking the path.
- Evidence to keep:
- photos of the doubtful stretches and a screenshot of the map in the app.

Clear obstacles from the path
- Who:
- you.
- How:
- go along the same route looking for anything that blocks the way to the destination and remove it. Then start the task again from the mower or from the app.
- Result that matters:
- a clear path from end to end between the mower and its destination.
- If you find something blocking the way:
- remove it and see whether the mower now completes the trip.
- If the path is clear:
- check where the charging station is installed.
- Evidence to keep:
- a photo of the obstacle and where it was.

Check where the charging station sits
- Who:
- you.
- How:
- see whether the station is under heavy shade or tucked among bushes. Segway says it then needs to move to an open area; follow the installation instructions in your Navimow manual when you relocate it.
- Result that matters:
- a station in an open spot the mower can reach easily.
- If it was hidden away:
- move it into the open and send the mower home again.
- If the station already sits in the open:
- check the VisionFence and the narrow passages on the map.
- Evidence to keep:
- photos of the old and the new location.

Clean the VisionFence and review narrow passages
- Who:
- you, with the mower powered off.
- How:
- stop the mower with STOP, power it off by holding OK and gently clean the surface of the VisionFence sensor. If the mower always gets stuck in one narrow corridor, adjust the map in the app to avoid that poor-signal spot.
- Result that matters:
- a clean sensor and a map that does not force the mower through weak-signal points.
- If the mower reaches its destination after cleaning or editing the map:
- keep an eye on that area for a few days.
- If 6021 keeps appearing:
- email Segway Navimow support with what you have gathered.
- Evidence to keep:
- screenshots of the map before and after the change.

What it means
Segway Navimow's official help center explains that code 6021 on the Navimow H means the mower fails to get to the place it is heading for. It asks you to check three things: whether the route crosses barren areas with almost no grass or stone paths, whether an obstacle blocks the way, and whether the charging station sits somewhere hard to find, in shade or in a bush. If none applies, it mentions an abnormal positioning signal in a narrow path or a stained VisionFence surface. The alert on its own does not show that any component is broken.
Warnings and stop conditions
- Mediumeditorial warning
Before putting your hands near the mower to clean the VisionFence or carry it, stop it with STOP, power it off with OK and wear gloves: the blades can cut even when the disc is still.

Symptoms and causes
Probable causes · in order
- Grassless stretches on the routeCommon
A barren patch with almost no grass, or a stone path with some grass between the stones, can stop the mower from finishing its trip.
Evidence: (Navimow H) My Navimow H is displaying error code 6021. What should I do?
- Obstacle in the wayCommon
Segway lists obstacles blocking the way to the destination; as long as they stay there, the mower cannot complete the journey.
Evidence: (Navimow H) My Navimow H is displaying error code 6021. What should I do?
- Charging station in a hard-to-find spotPossible
A station installed in shade or tucked into a bush is, in Segway's words, hard to find; the fix is to move it to an open area.
Evidence: (Navimow H) My Navimow H is displaying error code 6021. What should I do?
- Weak positioning signal or stained VisionFencePossible
In narrow paths the positioning signal can be abnormal, and a dirty VisionFence surface can also cause this error.
