Description
Segway offers three device families under the Navimow name that look similar but have different mowing units. This disc belongs to the small i series: i105E, i108E and i205 AWD. It comes with pre-assembled stainless steel blades and is swapped directly for the worn original disc—no adapters, no reworking.
Three models, one spare part
i105E, i108E and i205 AWD differ in mowing performance and equipment – but for the cutting deck, Segway has kept the same mounting. If you drive one of these three devices, you’ll use the same disc.
This is practical for households with two robots: one spare part on the shelf covers both, and even the Klingen are interchangeable with each other.
What matters is the separation by height and to the side: the larger i-models from i208 AWD and the entire H series each require a different disc. Which one it is can be found further below.
Compatible Navimow models
Which Navimow do I have?
The model names are very close to each other, and Segway has expanded the lineup over the years. These three questions clear up the most common mix-ups:
Replacement on the Navimow
- Switch off the robot and remove it from the charging station.
- Put on gloves, turn the device over, and place it safely.
- Remove grass clippings around the mowing deck—wet cuttings often stick here.
- Loosen the old disc, fit the new one, and tighten it evenly.
- Tap each blade once: It must be able to rotate freely around its screw.
The last point is the most important. If a blade gets stuck because the screw is seated too tightly, it cannot fold away during contact with a stone—and the force is transferred directly to the disc and the mowing motor.

6, 7 or 9 blades for the Navimow
The number of blades does not change the motor performance—it determines how often a blade of grass is hit on the same run. Which setup makes sense depends on the mowing interval.
6 blades – factory setup with center cover
The version that matches the original. The robot behaves as before, and the battery runtime remains the same—the right choice if you simply want to replace the worn mowing disc.
This version is the only one that has a closed center; the 7- and 9-blade discs do not. The Navimow follows its paths with high overlap and thereby throws up a lot of fine clippings; part of it ends up under the chassis. The cover prevents it from getting stuck at the blade mount and slowing down the cutting edges.
For anyone who runs the robot on a schedule and doesn’t want to deal with the underside, this is the most straightforward option.
7 blades – for a well-groomed ornamental lawn
One more cutting edge, and the cut pattern becomes noticeably calmer. Because the Navimow mows with a clear overlap anyway, the additional cuts add up across the entire area.
Recommended when the lawn is kept short and mowed every two to three days.
Without center cover: On dry grass, it doesn’t matter much. If you let the Navimow run often in the early morning hours, you’ll be better off with the 6-blade disc, which requires less maintenance.
9 blades – for daily use
The densest blade setup shows its strength when the robot drives practically every day and only trims by a few millimeters. Then even the last blades standing individually disappear.
If, on the other hand, Navimow only goes through longer grass twice a week, the 6-blade or 7-blade setup is the more durable choice – nine narrow cutting edges wear out faster under this kind of load.
Also without center cover. With daily operation on short lawn, little collects under the chassis anyway.
Signs of dull blades
Buy blades individually
On the Navimow, the blades wear out while the mowing disc remains. If you order the 60-blade replacement set including screws at the same time, you’ll have everything at home for the next blade changes—and you can swap them immediately if needed, instead of waiting for delivery.
