The Navimow X3 robotic lawnmower scored very well in our review. However, its crowning feature of perfect edge mowing with an attachable edge trimmer leaves one crucial question unanswered.

The Navimow X3 from Segway definitely counts among the best and most powerful lawnmowers in 2025. The model features an innovative connector on the side to which various accessories can be attached, including a side trimmer for supposedly perfect edge mowing. Unfortunately, this is currently unavailable in the reviewer's homeland (Germany), so we were unable to include this exciting feature in our Navimow X3 review, but we'll try to do so as soon as it becomes available.

Even without this innovative solution, with which Navimow aims to solve arguably the biggest problem of current robotic lawnmowers with edge-free mowing, the Navimow X3 almost completely wins us over. While power consumption (especially in standby mode) is relatively high, the Navimow X315 impresses with high-quality and reliable mowing performance. The entry-level model is slightly slower than the two top models in the X350 and X390 series.

Systematic navigation in paths across the test areas generally worked without issue, but the mower requires an RTK antenna in the garden. Several additional cameras are mounted on the front and sides of the robotic lawnmower, which are used for obstacle detection. Here, too, the Navimow X3 performs almost flawlessly, our review shows.

Another point of criticism is that the entry-level model, the Navimow X315, with an RRP of $2,299 for a robotic lawnmower that can mow up to 1,500 square meters, is quite expensive compared to competitors such as the Mammotion Yuka ($1,399). However, the latter does not offer the option of connecting a module. The Navimow X390, suitable for up to 10,000 square meters, is no bargain either with an RRP of $4,999.
