Another big selling point is that since they’re battery-powered, they have zero emissions, which makes them a much more environmentally friendly solution to caring for your lawn. And not having a gas engine means very little maintenance other than charging batteries and cleaning out dried grass and dirt. To help you find the right fit for your lawn, I gathered five of the best robot mowers available to buy. I broke down their features and analyzed their maximum cutting areas to curate a list of robot mowers that will suit a variety of different needs.

The Worx Landroid L is my top choice for the best robot lawn mower. With the 8-inch cutting deck, it can mow lawns up to a half acre, which is perfect for most suburban lots. The cutting disc sits on a floating pivot to automatically rise and drop to follow your lawn’s terrain, reducing the chance of scalping or missing low spots. Built-in sensors help the Landroid L navigate around obstacles and through narrow paths, so you don’t have to worry about it getting caught in your flower beds or stuck between your toolshed and the house. A companion app for your smartphone or tablet allows you to check on battery life, set a mowing schedule, and even specify your lawn’s soil makeup and type of grass for more efficient mowing and overall care. A built-in alarm helps deter thieves, but if someone does manage to make off with your robot mower, the GPS-enabled companion app lets you track their whereabouts so you can recover your property. Pros:

Since robot mowers are such a new technology, they can be quite expensive. Fortunately, the Mowro RM24A is one of the more affordable options on the market, with a price tag that sits comfortably under $1,000. The 9.5-inch cutting deck and 28V battery allow the RM24A to mow yards up to a quarter acre, while the large rear, wheels help it tackle steeper hills and inclines. The brushless motor runs much more quietly than gas mowers and many other battery-powered mowers, which means you can enjoy your deck, patio, or backyard while the RM24A is mowing your lawn. And it won’t annoy the neighbors as it follows its 48-hour mowing schedule; this robot mower automatically mows every two days to keep a consistent cut across your entire lawn. It even has rain sensors to let the mower know it’s time to return to the docking station when storms roll in. Pros:

Cons:

No companion app for schedulingNo anti-theft system

Since robot mowers run on either interchangeable or integrated batteries, they’ll need routine charging for optimal runtimes. Unfortunately, that also means you could get stuck waiting for your mower to charge before it can finish cutting the grass. The Husqvarna 115H has one of the fastest charging times, reaching full battery in just about an hour. You can tackle other outdoor chores like edge trimming and pulling weeds while you wait, and you won’t have to schedule mowing over several days to allow for charging times.  The 8.5-inch cutting deck lets the 115H mow up to a quarter acre; and with its lift and tilt sensors, the blades automatically stop if the mower gets picked up. This protects pets, kids, and adults from getting hurt if the mower gets stuck on an object or if it gets flipped over. The integrated anti-theft alarm only can be shut off with a specified PIN number, meaning thieves can’t disable the alarm before making off with your robot mower. Pros:

Robot mowers are usually meant for much smaller lawns, but the Husqvarna 430X is capable of handling lots up to almost a full acre. The 9.5-inch cutting deck features three blades that mulch clippings into ultra-fine pieces to re-feed your lawn between fertilizer applications. The large rear wheels enable the mower to handle steep inclines. With Bluetooth connectivity and GPS navigation, the 430X lets you schedule mow times, set up remote start points, and even set up profiles for different sections of your yard. This lets you create a custom schedule for a consistent cut across your whole lawn, while remote start points mean that your robot mower isn’t limited to where the base station is when you want it to tackle a particular section.  You can even choose between spot mowing and spiral mowing. The spot-mow mode lets you quickly tackle small areas the 430X may have missed or may be growing faster than other sections of your lawn, while the spiral-mow mode provides a consistent cutting pattern. Like its cousin, the Husqvarna 115H, it has a built-in alarm to alert you to would-be thieves and only can be disabled with a personalized PIN. It also offers GPS tracking in case someone does manage to make off with your new mower. Husqvarna also offers interchangeable top covers to either make it easier to see where your 430X is in your yard or to match the rest of your lawn and garden equipment. And if you want truly hands-off lawn care, you can connect the 430X to your Alexa or Hey Google smart speaker for voice-activated controls. Pros:

Robot mowers tend to have very short runtimes, but the Greenworks Optimow 50H provides up to 2.5 hours of mowing on a full charge. It also has a fairly quick charge time of just 70 minutes, so you can tackle other outdoor chores or enjoy your patio or deck while it recharges; and you won’t have to worry about scheduling mow times over several days if your lawn is on the higher end of the Optimow 50H’s limits. It’s rated for lawns up to .75 acres, and the 9-inch cutting deck is designed to have the blades fold inward if they connect with an object. This protects the blades from damage while also preventing the mower from getting hung up on things like rocks, roots, or outdoor toys. The body of the mower is IPX67 rated waterproof, which means that if you notice dirt and grass buildup, you can quickly clean it off with a typical garden hose without worrying about ruining the motor or charging connections. The Optimow 50H also includes a safety key that can be used on the underside of the unit to disable the cutting deck; this is perfect for keeping kids and pets from accidentally starting the mower and getting hurt. There’s also an integrated carrying handle for easier maneuvering if you need to clean or perform maintenance like blade sharpening.  Pros:

Cons:
