What is a Robotic Lawn Mover

A robot lawn mower is exactly what it sounds like. It's a battery-powered automated robot, that moves around on wheels and trims grass with razor blades on its bottom. Such mowers come with a docking station, used for recharge, and a special perimeter wire for setting the boundaries. Some models also have such features a solar battery on top, which prolongs their working time. Many of them have an option to be programmed with a mowing schedule, and some other features.

Once all of the preparations are complete - the wire is laid, the station is connected to the power supply, the battery is charged, and the mowing schedule is set - the robot lawn mower will not require a human intervention and will work automatically. The cut grass is not collected in a bag, but rather left on the ground as the soil fertilizer, boosting the future grass growth. Thus, you will get a perfectly maintained lawn with healthy green grass without even having to go outside.

On a related note, we can also offer you our pick of the best hedge trimmers for keeping the green fences well-manicured. Also, you might be interested in the smart sprinklers systems, that can be scheduled to irrigate the flower beds and the grass in your yard during the desired time of a day even when you are away.

Best Robotic Lawn Mowers

What Features to Compare

Maximum Coverage. Some mowers are designed to effectively cut lawns of a specific size. Some of them can cover the areas of only 2000 sq ft, while others may patrol as much as over an acre. Thus, if you choose a model with the designated area smaller, than your yard, you might require moving the docking station from one zone to another, which is not exactly convenient.

Perimeter Wire Length. Unlike some robot vacuum cleaners, that can scan the room for possible obstacles beforehand, the mowers rely on the perimeter wire, laid along the borders of your lawn and around some obstacles that you don't want it to hit with its bumpers. Thus, check out beforehand how much wire you will need to cover the necessary area.

Sensors. As a rule, the mowers are equipped with several smart sensors that allow the robot to detect the perimeter wire or turn around when it bumps into an object that it can't push away. Another useful sensor is a rain detector, because the wet grass may clog the rotating blades. Additionally, such device with a lot of metal parts, staying on the flat lawn, may attract the lighting strike. So, when the rain sensor detects high humidity level, it will make the robot return to the docking station.

Programmable Features. A lof of the latest models can be scheduled to mow only during specific time of a day. Some of them may have an option to set the password for controls or configure different behavior scenarios for different situations and also change the mowing patterns. Still, in most cases, the mowers just move in a chaotic pattern by randomly choosing its direction. That way, your lawn will obtain the carpet-like look without the wheel traces on it. There are also models that feature linear and even spiraling mowing patterns.

Lawn Grass Types. Generally, most of the mowers' blades can cut down almost any lawn vegetation like grass or dandelions. Yet, some models may be an exception and struggle to cut high-maintenance types of grass with thick shoots like St Augustine Grass.

Robomow RC306

Rolling Around

The Robomow RC306 is the finest example of a robotic lawn mower that boasts great functionality. It's designed to trim average-to-large lawns and capable of covering up to 1/8 acres at about 60-90 minutes, depending on the terrain features. Although robot's movements may look chaotic, it tries to choose the most optimal path and mowing pattern for several lawn zones, owing to the various built-in sensors.

The Robomow RC306 comes with the 650 ft wire, that is used to set the boundaries for the cutting area and limit it off from the flower beds, ponds, and other places, you don't want it to go to. Even if this length is not enough, it's possible to buy the additional Robomow MRK0040A Perimeter Wire and join it together with the existing one via special adapters on each side. The Robomow RC306 package includes 250 pegs to pin the wire down to the ground. Furthermore, there's no need to worry about having your feet caught with it because the new grass will gradually grow over it. 

As for the decorative elements of your lawn like pots, tables with chairs, and other things, if the robotic mower can't push it aside, it'll turn around and move the other way. Simple as that.

Review of Robomow RC306 Robotic Lawn mower

Sensation and Perceptions

Okay, it can move around without breaking your stuff or running into the wild. Performance-wise, the Robomow RC306 is worth every cent. The cutting height can be adjusted from 0.6" to 3.1" for leaving the exact grass length as you like.

The weak point of many robot mowers is that you have to manually trim the edges, as their blades don't reach them. In this mode, there's a special Edge mode, that sets the device going along the wire, cutting the grass near and a bit over the border. This robot can run up 20° slopes and roll out of shallow pits. Even if the robots somehow tips over, the cutting blades will stop spinning automatically. 

Among its various sensors, the rain detector is one of the most useful ones as it sends the robot back to the docking station in order to keep it away from the water. Although the electronic part is pretty much water-resistant, the blades may get plugged with the wet grass or the wheels may leave the traces on the ground.

Cutting Edge Technologies

Underneath, this model features - a 3-blade disc, that rotates at a huge speed, delivered by an extra-powerful 200W motor.

 As for the controls, you can set the modes or switch it off via either control panel on top, or with the mobile app. With enough wire, it's possible to create several smaller working areas or even separate one and manually appoint the robot for each of them separately. This comes handy in the situations like when you need a time for the sprinklers to water one of them. It's also worth mentioning that you can control the robot remotely with the Robomow phone app for mowing in places, that it refuses to go to automatically. Of course, the app is available on Android and iOS devices alike.

The anti-thief feature blocks the commands unless you enter a pin code. And with the child lock on, the device can be activated only by pressing two buttons in a particular order.

As a result, this Robomow robotic lawn mower is one of the best models that money can buy. It's designed for the lawn, with about 5500 sq ft mowing area. Its sharp blades can cut down any type of lawn grass, while the big number of programmable features will allow you to have a well-maintained yard even without coming out of your home.

Milagrow RoboTiger 2.0

6th Sense

The Milagro RoboTiger 2.0 Robotic Lawn Mower will be a perfect choice if you are looking for an easy-to-use model with great functionality It's equipped with numerous sensors for its reliable performance. For instance, lift up and tilt sensors will stop the blade motor when the mower is lifted or moves up a slope, higher than 30°. Owing to the 2 rain sensors on the top, it accurately detects high humidity and returns to the docking station by tracing the perimeter wire. Of course, the same happens when the charge is low. There's also an option to set the password code and key-started operation. That way, nobody will be able to start it without one of the keys or the password.

It's also worth mentioning that a smart self-diagnostic function that will notify you in case of any malfunction or unexpected obstacle on the mower's path. The user manual has a pretty thorough guide on how many of these situations can be easily solved.

Review of Milagrow RoboTiger 2.0 Robotic Lawn Mower

Running Up That Hill

As we've mentioned, the mower can climb up and trim the grass on up to 30° slopes, which is greater than many other robotic mowers can do. The starting package also includes a 330-ft of wire for setting the working perimeter and 100 pegs to fix the wire to the ground. With the optional wire, it's possible to expand the maximum length up to 1,960 ft and use it to divide the area into the smaller bits. Then, the robot can be configured to mow each of them separately.

Note, along with fixing the wire with pegs, you can just lay it underground up to 2" deep, and the mower's sensor will still be able to detect it. That way, you alleviate the risk of a dog chewing the wire.

On a single battery charge, the RoboTiger 2.0 can process around 6,450 sq ft before returning to the base, while the maximum working area is approximately 16,100 sq ft.

The Art of Mowing

Instead of just one blade, this model has 2 short ones with 2 cutting edges each. Even if the first blade misses the grass, the second one should get it anyway. Their height can be adjusted for leaving the grass height at either 1.2" or 1.6" while moving either in spirals or in a straight line.

As the blades rotate at 4000 RPM rate, they can cope with the grass of any density. However, the tree branches on the ground may stop the blades from rotating. However, this model features overload protection that stops the motor in situations like this. Although the mower can't be programmed with a phone, it comes with a remote controller, which has 6-m operational range. Along with the settings control, you can manually send the robot in a specific direction or just command it to return to the docking station.

Overall, this Milagrow RoboTiger 2.0 Robotic Lawn Mower is a universal choice for anyone, as it offers decent functionality and is very easy to set up and use.

WORX WG794

Govern the Lawn

The price of robotic lawn mowers often varies from a thousand to several thousands of dollars. However, the Worx WG794 Landroid turned out to be a functional robot that comes at a considerably lower price than the other models. Its intelligent system is designed to effectively cover the mowing area of up to 1/4 acre (or around 10,800 sq ft). The housing design also allows it to trim the grass on uneven surfaces with the slopes at up to 20°.

Note, the package includes 200 pegs and 590 ft of the wire for setting the boundaries for the robot.

Review of WORX WG794 Landroid Robotic Lawn Mower

Cut and Slice

The cutting blade here has the same design as most Husqvarna robotic mowers. It has the shape of a disc with 3 small pivoting razor blades, attached to it with 1 bolt. When rotating at a high speed, these blades come out and cut almost any type of grass. However, if the blades strike against a stubborn obstacle like a branch or a thick scrub, they will just slide to the side, avoiding damage.

What's more, each blade has 2 holes and sharp edges on both sides. Such design grants much longer service life, as when one side becomes dull, you can just flip it over or attach it to the disc with another side. Also, you can adjust the cutting height manually from 1.6" to 4", leaving the grass length exactly as you need it.

Additionally, the package includes 9 blades in total. Each one stays sharp for about 4 months while being used every day. Thus, you are provided with up to 12 months of daily mowing. Just don't forget to switch them and clean from the dirt and mulched grass.

Automated Lawn Mower

The WORX WG794 Landroid offers almost fully automated performance and is equipped with numerous sensors, including the rain one. That way, you can program the schedule and don't have to worry that it will start cutting the grass when it's raining. Thanks to the bumping sensor, there's also no need to set the perimeter wire around the trees, poles, and other objects in the yard. Still, if you have deep pits or shallow flowerbeds in your yard, we strongly recommend running the wire around them to prevent the robot from falling into one.

A single battery charge provides around 40 minutes of active mowing before the robot returns to the base. A full recharge takes only 45 minutes, which is also a great result, compared to many other models on the market.

The bottom line - we can recommend the WORX WG794 Landroid Robotic Lawn Mower with a well-balanced functionality for owners of the average-sized lawns. If you are looking for an inexpensive, quiet-working lawn mowing robot and not afraid of having to switch the blades manually every month or two, we can recommend you this mower.

Husqvarna Automower 315

Choose Your Size From The Start

The Husqvarna Automower 315 lawn mower features all the modern features for keeping your yard in a perfect state. Notice, on Amazon, you may find several options with different lengths of a perimeter wire and a number of included wire pegs.

In terms of capacity, this mower can cover the area of up to 0.37 acre by setting the timer. It moves in a chaotic pattern, never repeating it. That way, it guarantees that the lawn is trimmed everywhere, with no trace being left out of its route. In case you have narrow passages in the yard, you can ensure that the robot will go there too by laying a guide wire.

What's more, unlike many other robotic lawn mowers, the Husqvarna Automower 315 can cut the grass even during the rain, although it is not recommended to do, as the wet cut grass tends to clog and stuck to the blades. So, you can set the robot's behavior scenario choosing whether it continues to mow under the rain or returns to the base when a high humidity level has been detected.

Review of Husqvarna Automower 315 Robotic Lawn Mower

Managing the Performance

Fun fact: the Husqvarna 315 lawn mower works quieter than an average vacuum cleaner. Still, its razor blades effectively cope with the grass of varying density and thickness. You can manually adjust the cutting height within 0.8"-2.4" with a simple turn of the knob, hidden under the lid on top. Cutting the grass on small slopes also won't become a trouble as the robot can go up and down at a 22° slope. All the while its 3 pivoting razor blades, set on the rotating disk, evenly cut the grass at 8.7" width, leaving the strip of trimmed grass behind. 

If you notice that the grass grows faster than the mower can cut it, you can set the special Weather Timer so that the robot keeps cutting the grass longer during the periods of intense grass growth.

Overall, one of the greatest characteristics of this model is that you can fully program its behavior in a variety of scenarios. The included user's manual has a detailed guide on how to set each of them. This comes especially handy if you have lots of narrow passages in your yard or many trees or other obstacles in the garden.

Husqvarna Automower 315 Robotic Lawn Mower in the use

Extras and Features

Even the starter package includes 9 extra razor blades. Each of them has 2 cutting edges. Thus, when one side becomes dull, you can just flip it and set it back. If you have kids or pets in the yard, you can prevent the mower's accidental activation by setting a pin-code password. The mower will stop the motor when the tilt is greater than 20°, allowing you to safely lift it up and move to another area or to the base. However, the mower also detects the low battery level and returns to the docking station automatically.

Summing up, this is one of the best lawn mowing robots that can be found on the market. If the high price doesn't stop you, this is a go-to mower. It will also be an exceptional choice if there are many narrow passages in your yard or garden.

Robomow RX12

Expecting the Miracle

The Robomow RX12 model is the most expected robotic lawn mower of Spring, 2017. Mostly, because of the incredibly friendly price and rich functionality.

It features a capacious battery that provides from 90 to 120 minutes of a mowing time. It has a single 7" cutting blade with adjustable height from 0.6" to 1.7". Furthermore, the mower can effectively cut the grass at up to 8.5° slopes. It doesn't have a navigation wheel like most of the other models, but it uses its 2 large wheels to push itself around. It also features a floating deck underneath that follows the terrain features.

Review of Robomow RX12 Robotic Lawn Mower

Light and Simple

This Robomow lawn mower is very convenient. Its modular design allows you to quickly detach almost any part for cleaning or changing. Just like any other robotic mowers, it automatically returns to the docking station when the charge is low.

The acid-lead battery allowed to dramatically reduce the price. The payback, though, is that it takes almost a single day to recharge it. For the same reason, its mowing area is only 1/20 of an acre, making this robot suitable for small yards and gardens only.

Anyhow, the built-in sensors allow it to follow even the narrow passages and trim the grass, including the lawn's edges. Speaking of the perimeter, the package also includes a wire and pegs for laying it around your yard.

Robomow RX12 Robotic Lawn Mower in the use

Easy Setup

Well, the Robomow RX15 mowing robot probably has the most simplified controls, that we've seen in such devices. It has one on/off button and another one that just sends it to the base. That's it. No LCD screen, no fancy phone app for schedule programming. Zilch. Nada. You just plug it in, turn it on - and the mower handles your lawn all by itself. Owing to the chaotic mowing pattern, it tends to never go over the same path twice.

Concluding, this inexpensive robotic lawn mower can become an ideal solution for small yards and gardens of up to 2,000 sq ft in size.
