Description
The H Series was Segway’s entry into cordless robotic lawnmowers and has been running in many gardens for years. That’s exactly why replacement parts are needed here: If you maintain the robot, you can keep it running for a long time— a new mowing disc costs only a fraction of a new unit. This disc fits H500E, H800E and H1500E, including the VisionFence versions.
A disc for all three H models
H500E, H800E and H1500E differ in area performance, but they share the same mowing deck. The number in the name indicates how many square meters Segway the device is intended for—nothing changes on the disc.
The VisionFence variants, recognizable by the suffix VF, also use the same disc. The additional camera is mounted at the front of the housing and has nothing to do with the cutting system.
So if you’re still using a first-generation device, you’ll get a replacement part here that exactly matches the factory version—no modifications, no adapters.
Compatible H models
H-series or i-series?
“H500E or i105E” is one of the most searched comparisons around Navimow – and at the same time the most common cause of errors when ordering replacement parts.
Replacement on the H series
- Switch off the robot and remove it from the charging station.
- Put on gloves, turn the device over, and place it down securely.
- Clear the mowing area of old cuttings—on devices used for longer periods, dried-up felt often sticks here.
- Loosen the old mowing disc, fit the new one, and tighten it evenly.
- Tap each blade: It must be able to rotate freely around its screw.
For devices that have already been in use for a few seasons, it’s worth replacing the screws instead of reusing them. Worn heads are difficult to loosen next time.

6, 7, or 9 blades for the H series
All three configurations fit the same mount. Which one makes sense depends on how often the robot runs and how short the lawn is kept.
6 blades – factory configuration with cover
Matches the original: same number of blades, same cutting behavior. For anyone who wants to simply replace the worn mowing disc without changing anything about the mowing behavior.
Only with this configuration is there a cover over the center of the mowing disc – it is omitted with 7 and 9 blades. With the H models and their flat design, this has noticeable effects: the distance between the chassis and the ground is small, so a lot of clippings are pushed inward. The cover keeps the area around the blade mount clear instead of allowing it to clog.
If you run your device for years and want as little maintenance as possible, this is the most straightforward option.
7 blades – for well-kept areas
One cutting edge more, visibly more even cutting. Useful when the lawn is kept short and the robot runs at short intervals.
With the H models, which often handle larger, contiguous areas, this is noticeable especially over the area itself – the cut looks more closed.
Here without center cover. If you let the robot run mainly in dry weather, you’ll hardly notice it.
9 blades – for short-cut lawns
The densest variant is worth it for daily operation on a short-cut lawn. The cutting pattern is very even; individual blades left behind are hardly noticeable.
If, on the other hand, the robot only runs twice a week and has to cut down longer grass, the 6-blade or 7-blade setup is more robust.
Also without coverage over the middle – in practice uncritical for short, dry grass.
How you can tell the mowing disc is due
Buy blades individually
Especially with older devices, it’s worth having spare blades at home: The 60 cm replacement blades set including screws is enough for many replacements—and fresh screws are the better choice for robots that have already been through a few seasons.
