The Best Robot Lawn Mower of 2025

The Husqvarna Automower 450XH EPOS is a boundary-free robotic mower that relies on satellite positioning to maneuver around a yard. The associated app allows you to create and manage mowing zones, stay-out areas, mow patterns, cutting-height adjustments, and more. In our testing, it worked well beyond its listed capabilities, proving itself to be an excellent lawn-maintenance tool. It’s not ideal for every lawn—using it involves some annoyances, and it needs good satellite reception and a wide-open sky. But in locations where it’s a strong fit, it’s worth considering, even with its nearly $6,000 price tag.

The package consists of four parts: the mower, the charging station, the reference station, and the app. You have some restrictions on where to set the pieces up, due to the system’s reliance on satellites. According to the manual, the reference station, which looks like a weather station, should have 160 degrees of clear sky above it, so installing it up high and on a pole is recommended. Don’t mount it on the side of a building. Note that the reference station is responsible for the heightened accuracy of the mower—down to about a centimeter—so if the installation is loose, and the reference station moves or swings around on the mounting pole, the entire lawn map will shift accordingly.

You have two ways to connect the phone app to the mower. Option one is Automower Direct, which uses Bluetooth; option two is Automower Connect, which uses cell reception. Certain features, such as mapping a mowing area, appear in the app only on the Bluetooth connection. The cellular connection lets you control the mower from any remote location (though we had problems setting it up). You can also connect the mower to Amazon Alexa or Google Home.

The most time-consuming part is setting up the mowing areas. You accomplish this by driving the mower around the edge of the defined area, using the app as a controller, and marking points to create the boundary. Once you’ve established the perimeter, you can create stay-out zones for objects such as flower gardens, a birdbath, a child’s play structure, a tree, or a berry patch. Finally, you create a path for the mower to return to the charger. You can create multiple areas, too. Depending on your property or yard, this can be an involved process, and figuring everything out takes a while. Thankfully, once you’ve established an area, you can move the boundary points; in our tests, after the mower cut an area a few times, we could see where our initial points were off and could make slight adjustments.

With the mowing areas established, the fun begins. You can customize each work area with its own schedule, mowing height, and mowing pattern. Because everything happens through satellites, the mower can also work at night (it has headlights that you can turn on for safety), in the rain, or whenever is convenient. For example, the kids get home from school and often play in the yard around 3 p.m., so we kept the mower off-duty at that time.

We were surprised by how well it could handle our test lawn. All set up, our lawn had eight mowing areas and 21 stay-out zones. Mowing that lawn with a riding mower typically takes approximately two hours, once a week. Going all mowing season long with the Husqvarna Automower 450XH EPOS, that will be at least 50 hours we’ll have back. We’ll also have no need to deal with refilling gas, changing oil, or winterizing an engine.

The mowing patterns are customizable. We kept things simple with a straight-line mow pattern, but you can also choose a cross pattern or a triangle pattern. You can fully customize the direction of the mow lines, as well, so you can have them run parallel to the front of the house, perpendicular, or at any angle you want. Unfortunately, you can’t mow words into your yard. (Everyone asks that question.)

It cuts with three small razor blades attached to a spinning disk. The blades are double-sided, and each time the mower goes out to work, it reverses the direction of the spin, adding life to the blades. Husqvarna recommends changing the blades every six weeks or so—a simple process that you can do with a screwdriver. The cutting path is roughly 9 inches, and the body of the mower is about 28 by 21 inches, so the design puts a good 7- or 8-inch buffer zone between the edge of the body and the spinning blades, far more than on a push mower.

For added safety, it has a sensor. When the mower encounters an object that is not programmed as a stay-out zone—such as a person, a picnic table, or a delivered package—it slows down so that it bumps the object at a very low speed. Once it feels the bump, it reverses and starts to figure out how to get around the object, a process that often leads to a lot more bumping and a lot more reversing. We found that it’s easiest to create a stay-out zone through the app for any object that will be on the lawn for more than a day or so, such as a kiddie pool, but that gets tedious if you have a busy lawn.

But it does not detect smaller items. You need to clear your lawn of stuff that’s small enough to fit under the mower’s housing. We found this task especially tricky with four kids living in the house. Because we had scheduled most of our mowing for the nights and early mornings, each evening we needed to do a thorough check for baseballs, hula hoops, cornhole bags, sweatshirts, dog toys, socks, and anything else strewn about.

Hitting something might not be a disaster. On a couple of occasions, we missed an item, but the damage was minimal. The blades are smaller than a traditional mower blade, and they’re hinged to the spinning disk like a flail, so if they hit something, they’re designed to spin out of the way. A baseball that got run over had only a few nicks on it—a significant difference from all the baseballs we’ve chopped in half with a traditional mower.

Security and privacy don’t appear to be an issue with the app. As we do for all app-based devices, we sent a security and privacy questionnaire to Husqvarna, asking about the company’s security policies and practices for handling a device owner’s data. Among other concerns, that includes login practices, whether the company supports two-factor authentication, what user data is encrypted, and what data is recorded and shared. Husqvarna’s responses were standard for what we’ve seen and didn’t raise any questions.

Not surprisingly, it’s expensive. The mower and charging station together cost about $5,000, and the reference station adds $800. You can purchase the Husqvarna Automower 450XH EPOS only through an authorized dealer, who can do the installation at an additional charge, though we think a moderately handy person should be able to perform the install themselves.

That is a lot of money, but the multi-acre capability of the 450XH EPOS, not to mention the convenience and having a lawn that always looks freshly mowed, makes it comparable to a riding mower or a zero-turn mower, which are up in the $2,000 to $6,000 range, depending on the size and features. Add in the time you recover by not mowing, maintaining, or winterizing, and the value of this Husqvarna robot mower starts to come into focus.

Flaws but not dealbreakers

Cluttered or busy lawns make for a stressful experience. As we mentioned above, the mower can be difficult if your lawn is an ever changing landscape of toys, patio furniture, vehicles, and clothing. With four kids in our test house, things got so difficult that we took the mower off its schedule and activated it manually every couple of days—but only after a thorough yard tidy where we got all of the jump ropes, tennis balls, sweatshirts, and flip-flops cleaned up. We also found that outdoor seating areas, like fire pits, can cause issues. The pit itself can be programmed as a no-go area, but the shifting positions of the chairs around it had the robot mower spending way too much time bumping around the legs of the chairs, not getting to spots, making a bit of a mess of the mowing pattern, and finally getting completely trapped.

The app is functional, but it has room for improvement. Using the app is mostly intuitive, but at times we were confused about how to navigate it. We also would have appreciated more mapping features, such as the ability to add a mapping point to an existing work area, and we found other little things, like inconsistencies between metric and US measurements. When we spoke to Husqvarna representatives, they indicated that the app and the satellite technology in general are still evolving, so we expect to see incremental improvements to both.

Satellite coverage can be an issue. During our testing, the Husqvarna mower exceeded its documented capabilities, working fine in many spots where it had no line of sight with the reference station, but it did drop out of satellite communication under dense tree cover or when it was directly against a two-story structure. Often it would recover on its own, but other times we had to manually restart it. If you’re not sure about the density of your tree cover, it’s a good idea to have your lawn looked at by a Husqvarna dealer prior to investing in the mower.

Cloud? Bluetooth? Hello? We had problems connecting to the mower through the cloud. This was probably due to the lousy cell reception at the test property, and it’s likely not a universal issue, but it did limit what we could do with the mower. Because we could connect only via Bluetooth, we needed to be within close proximity in order to control the mower. So if it was raining out or if it was nighttime, and we wanted to change the schedule or stop the mower, we needed to suit up and head outside, instead of making the changes from our living room.

Most manufacturers we spoke with agreed that there are still some properties where a boundary-wire robot mower is the better fit. Some properties, for example, may have too much tree cover, or they might be simple and small enough for the lower cost of a boundary-wire mower to make more sense. Right now, the Husqvarna Automower 450XH, the boundary-wire version of our pick, costs almost $3,000 less.
