Frequently Asked Questions

Question: What is the cost to extend the cellular plan after the two year service plan runs out? Are you able to create zones to direct mowers to areas difficult to navigate along the guide wire?


The app is free for 2 years and then will be ~$29.99 / yr after!

Yes, the guidewire is used for a safe and quick return to the charging station if you have narrow passages or to assist the mower in navigating to remote /difficult areas. The guidewire needs to be connected to the boundary wire in one end and to the charging station in the other end.

Question: What heights are possible?

Answer: Choose from 32 height options between 2.4 - 4" for your lawn's best cut.

Question: I have an existing invisible dog fence that I no longer use, could I use the same wire I used for that to setup perimeter for the mower?

Answer: This unit includes 600ft of boundary wire for set up! To confirm whether the wire from your invisible fence could be used, we would need to know the gauge and conductivity of it.

Question: For a 1/2 acre empty lot, how long will it take to mow +- 20 ? Some others also say if you mow every other day, the blades have to be replaced at least once a month?

Answer: This unit is suitable for yards up to 1/2 acre. With the new battery, charge time is around an hour and mow time around 1.5 hours. Terrain and types of grass will affect the actual run time received. Run time truly is not a huge factor when dealing with robotic lawnmowers. If the battery begins to die while the mower is out, it will return it back to its charging station and then continue once changed. It is important to not fall into traditional mowing mindsets when talking about robotics as it is a very different concept.

Question: Will it move and work on a thick St Augustine grass. I had a husqvarna and it could not handle St Augustine.

Answer: Yes
