Once set up, the robot works autonomously. And it saves us at least 1½ hours per week. Exactly what we bought these for. We have approx. 200M² of grass and have therefore bought this version of 600M² so that we are sure that the robot can handle this. Well, not so. We have set the robot to mow for 6 hours every day. Unfortunately, the battery is empty after 1½ hours of mowing and then it takes over an hour to charge and then it can be used again for 1½ hours. Very bad!

I chose this smart variant because of the combination with a gateway, which means that communication with the robotic lawnmower does not necessarily have to be within 10 meters. Installation was fairly labor-intensive (I have a main area and a secondary area); I chose to work the wiring 10 cm into the ground to be able to continue scarifying the grass (140 meters of wire in 2.5-3 hours). When the robotic lawnmower initially started, a message came up about a damaged boundary wire. At first it was a bit of a shock, but it soon turned out that the connector containing the boundary wire and the control wire had not been properly tightened. Installing the mowing schedule via the app is super convenient, as is setting the extra options, including a connection with the Google Home voice assistant. From now on a pleasure to watch .. 'Hey Google, dock my mower'!

It's a great robot that does its job well. It's quiet and practically never gets in the way. Setting up the wires does require some explanation, as there are a few rules to consider. However, for a simple, rectangular setup, it's not too bad. Once the wires are laid, they do get overgrown quite quickly. Laying the wires is a bit of work, but it doesn't take hours. Just make sure you bury them in the ground if you still want to use the scarifier.
I wanted one with a wire because it could easily drive into a chasm. If a GPS model has a 10-meter error, it could just shut down. This model also stops completely if the wire signal is lost. Ideal for my situation.
It's a bit of a shame that the robot can no longer be started from the onboard display when it's connected to the smart gateway. That has to be done via the app.
