Description
The large i-models from Segway use LiDAR sensor technology and cover areas where the robot is on the go every day. Their mowing unit is designed to be larger than that of the i105E series—an disc from the small series does not fit here. This disc is made for i208 AWD, i215 LiDAR and i220 LiDAR and comes with pre-assembled stainless steel blades.
Why the large i-models demand more
An i220 LiDAR is designed for around 2,000 m², an i215 for about 1,500. No robot can handle such areas in a single pass—it sets off multiple times a day and covers distances over the week that are far beyond what a device in a townhouse garden would do.
For the cutting performance, it’s exactly this running time that matters. Wear isn’t determined by the size of the garden, but by the number of meters each blade pulls through the grass.
On top of that, there’s LiDAR navigation: these models drive closer to flowerbeds, edges, and obstacles than older generations. This produces a clean mowing pattern right up to the border—and more frequent contact between the blades and lawn edge stones.

Questions about the Large i-Series
Segway has expanded the i-series across multiple generations. These points most often cause uncertainty:
Replacement in just a few minutes
- Switch the device off using the button—don’t just pause it in the app.
- Put on gloves and lay the robot on its side.
- Loosen any collected clippings around the mowing deck.
- Unscrew the old mowing disc, attach the new one, and tighten the screws crosswise.
- Finally, briefly tap each blade— it must be able to rotate freely around its screw.
With the larger i models, it’s worth clearing out the wheel arches right away. If you’re working under the device anyway, this saves you a second maintenance stop.

7 or 9 blades
For the larger i-models, we offer two configurations. Both fit the same mount—the difference is how often a blade of grass is hit along the same path.
7 blades – for regular operation
The balanced choice for areas that the robot processes in multiple passes per week. Seven cutting edges provide a clean cutting pattern without spreading the work across too many edges.
On large properties with different zones—short ornamental lawn in the front, more robust growth in the back—this is the option that works everywhere.
9 blades – for daily operation
If you let your i215 or i220 run every day and keep the lawn consistently short, then nine cutting edges deliver the densest cutting pattern. Individual blades that remain standing—sometimes left behind on longer passes—disappear in the process.
During longer mowing pauses, the advantage is reversed: nine narrow blades share the same workload and therefore dull earlier. For areas with more vigorous growth, the 7-blade setup remains the more durable choice.
When it’s time for a new set
Buy blades individually
With two passes a day, operating hours add up quickly—and the entire set is always replaced, never individual blades. The 60-blade replacement set with screws covers multiple replacements and is ready whenever the lawn needs it.
