The new Segway Navimow i-series models offer a number of improvements over the previous H-series, including:

* Improved navigation stability and accuracy, with fewer pauses and better performance in areas with poor GPS coverage.

* Enhanced obstacle detection and avoidance, with the ability to detect and navigate around branches, leaves, and other objects.

* A new “Auto Assist” feature that allows the robots to create their own mowing paths and avoid collisions.

* Improved mowing performance in areas with thick grass or weeds.

* A more affordable price point, with the i105E priced at 999 euros and the i108E priced at 1299 euros.

However, there are also some limitations to the new models, including:

* A limited mowing area of up to 500 or 800 square meters, depending on the model.

* No electronic height adjustment feature.

* No front bumper or blade-halt sensor.

* No 4G connectivity.

Overall, the new Segway Navimow i-series models offer a number of improvements over the previous H-series, but may not be suitable for larger mowing areas or those with more advanced features.
