In a recent post, I talked about the usefulness and practicality of robot lawn mowers. In it, I come to the conclusion that these interesting devices have definitely got their limits, but that in certain use cases, they can be very useful and even fun. In my research, I also found that some robot lawn mowers are surprisingly capable and worth having. These, naturally, are among the higher-end models. However, if you have a large lawn on terrain that isn’t too wild, some robot lawn mowers can be very useful indeed.

Best Robot Mower for Large Lawn: Automower from Husqvarna

I found a few models that are powerful, capable, and just downright fun to watch on a clear and sunny afternoon. To that end, here are the best robot mowers for heavy-duty use.

The Best Robot Mower for Large Lawn & Heavy Duty Use

The one thing the mowers on this list have in common is that they are higher-end models. This means these are not $500, budget machines. However, they are powerful, impressive, and can stand up to some fairly heavy-duty use. Of course, they will never be as capable as a human being and a traditional petroleum-powered mower, but they can certainly save you a significant amount of time and effort in keeping your yard neat and tidy.

For the price, the power, and for the overall capabilities, this mower is pretty much unbeatable. When it comes to value, this one breaks the rule that you can’t get a quality robot mower for less than $1500. The Automower from Husqvarna applies durability and power where it counts without any of the unnecessary flourishes that are common in high-tech devices. To prove its true value, this mower can even operate in the rain. That, plus its powerful motor and big wheels give it the ability to tackle some really tough lawns. It’s simple, affordable, and packs a punch where it counts and may be the robot lawn mower for large yards.

Robotic mower smart SILENO life is one of the most high-tech-looking robot mowers out there, and it is as high-tech as it looks. Unlike many robot lawn mowers, it does have app support. You have complete access to settings and the ability to control the unit through your phone. It is also able to handle more rugged terrain than you would expect, but not as much as a unit that specializes in tough lawns. Its battery life is just over an hour, which might be enough. If not, you may need to supervise it through a recharge and restart. While it may not be the best robot lawn mower for large lawns, for smaller yards, it is more than sufficient.

Another powerhouse from Husqvarna, the 435X offers a unique appearance and impressive capabilities. Where it really shines is in its ability to maneuver through tight spots and twisty paths. It goes over hills and bumps almost as well as the Automower 115H, and the build quality is really second to none. It is a large robot lawn mower and it’s not the best time saver, but if you have a lot of obstacles on your lawn like BBQs and kid’s toys, this mower might save you from having to rearrange them every time it powers up.
