Robomow _RS612

Packing Massive Punch

The Robomow RS612 packs a massive punch. It is the most expensive robot mower on the list but the price makes total sense considering its performance and overall convenience. Incorporating dual blades with combined 22-inch cutting width, the model has no issues covering larger yards up to 3/4 acre (32,760 square feet). Plus, the robot cuts and travels on slopes up 20 degrees/35% grade. You can adjust the cutting height between 0.8 and 3.4 inches according to your needs at any time.

With its numerous features, the mower is lawn-friendly, user-friendly, and family-friendly. You can download the My Robomow app, connect via Bluetooth, and manage the mower from any place, any time you want. You can even use the Alexa smart home ecosystem to make the mower cut your grass on voice command.

The model couldn't be easier to set up. All you have to do is peg wire around the mowing area's perimeters, set weekly mowing schedule, and let the Robomow go to work.

There are many little details that separate this high-end robotic lawn mower from its mid-range counterparts. The integrated rain sensor makes sure the robot returns to the base station in rainy weather and starts again when the weather conditions improve.

The model's unique edge mode and “cut beyond the wheel” design deliver the most excellent-looking finish on your edges. As per usual, you can program the robot to automatically travel and mow in different zones within your yard, returning to the base station after completion.

Review of Robomow _RS612 Robotic Lawn Mower Small Yard

Quiet Despite the Overwhelming Power

The product isn't flawless but it is pretty darn close. As far as we're concerned, the only major downside is that the battery takes almost two hours to recharge.

On the bright side, the model can barely be heard when standing ~20 feet from it. Considering its specs, the mower's motor is ridiculously quiet, quiet enough to mow at night without inconveniencing your neighbors.

The built-in anti-theft alarm makes sense too given how expensive the model is. In case the mower is removed from its designated area, the alarm will sound. Plus, you can activate a 4-digit PIN code. The mower will not operate unless the correct PIN code is entered.

Without boring you any further with the details, the Robomow RS612 is the best robotic lawn mower in the high-end but not overly expensive price range. The model is as practical and overall convenient as it is powerful and effective.

Husqvarna 115H

Uniform Cutting Result

The Husqvarna 115H is everything. The company designs and manufactures the most well-balanced robot mowers around and the particular model is no exception. There are many little details that contribute to the model's practical build and effortless/effective performance.

The huge black knob below the hood will let you adjust the cutting height. The model's free movement pattern makes sure the lawn is always perfectly cut, delivering that beautiful, carpet-like look.

The mower's razor-sharp blades work wonders cutting the grass from all directions, making sure it grows even stronger than before. Plus, this approach prevents moss growth. The model cuts smaller pieces compared to your average robotic lawn mower but on a much more frequent basis, making sure the lawn stays nice and healthy.

Incorporating strong carbon steel mounted onto a robust cutting disc system, these razor-sharp blades aren't just effective but durable too, delivering efficient operation and especially low energy consumption.

The model can be outside around the clock, designed to function properly and unattended under any weather conditions. It is built to withstand the harsh Nordic climate without any substantial issues.

The uniform cutting result throughout the lawn is achieved mostly because you can start the mowing at three different remote locations along the company's patented guidewire. The larger the grass area is the better and more important several starting points are.

Review of Husqvarna 115H Robotic Lawn Mower

No Passage is too Narrow

When the mower is lifted off the ground or tips over, the cutting progress automatically shuts off. Plus, the blades rotate far from the machine's outer edges, meaning that whenever the mower meets an obstacle, it is able to stop and redirect itself without causing any damage.

Apart from that, it is the little things that we've seen before in high-end robotic lawn mowers. You can set a PIN code. You can activate a high-sounding alarm to make sure nobody carries the mower away.

The aforementioned cutting system makes sure the model works as discreet and quiet as these mowers come.

The high-resolution, medium-sized display incorporates graphic menu structure. The interface is easy to figure out and the machine takes very little time/effort to set up.

Bottom line, the Husqvarna 115H doesn't have any major flaws and doesn't present any challenges. The model is as effective and efficient as they come. Plus, the machine is able to automatically sense narrow passages and carefully follow the guidewire through these small, narrow passages.

Gardena R80Li

Eco-Friendly Assistant

The Gardena R80Li has quite a few tricks up its sleeve in order to attract a number of different customers. First things first, not dissimilar to the majority of mid-range and high-end robotic mowers, the model operates on a rechargeable lithium-ion battery. That means zero emissions compared to orthodox lawn mowers that run on gas and far less environmental factor compared to disposable batteries. As you would imagine, that makes the model in question a great choice for environmentally conscious people as it will allow them to reduce their environmental footprint.

The question of environment aside, robotic lawn mowers can be as complicated as the next sophisticated piece of technology, which is why the manufacturers of this one made sure to design a model that is easy to install and just as easy to use and maintain. All you have to do is set up a boundary wire around the edges of your lawn and any large objects and you should be good to go. 

Speaking of those edges, the model offers about 65 minutes of runtime, which given the average cutting width of 6.69 inches and between 0.8 and 2 inches of cutting height should be enough to handle under 9,000 square feet of land. And if not, it takes the mower about 50 minutes to recharge and go back to the grass cutting task.

Review of Gardena R80Li Robotic Lawn Mower

Improve Your Garden

By the way, we probably would be remiss not to mention the fact that this robotic lawn mower doesn't just cleave a large part of the grass but instead cuts the tips with razor-sharp blades. Since grass clippings remain on the lawn, they serve as a natural fertilizer, thus allowing your grass to grow without any chemical interventions. 

Other than that, the mower will be able to handle a maximum slope of up to 25% (14°), which should be enough for your average lawn with some uneven terrain here and there. And, again, not dissimilar to the majority of robotic mowers, the model includes chaotic moving patterns and is capable of maintaining several mowing zones.

As for the features, the robotic lawn mower from Gardena comes equipped with both an audible alarm and a PIN code, so you wouldn't have to worry about a jealous neighbor stealing your robot from you.

Furthermore, you won't have to hide the model when it starts to get slightly drizzly outside as it can perfectly work during rain. It doesn't produce a whole lot of noise either, so that scoundrel neighbor of yours wouldn't be able to complain about that either.

Finally, the mower is fairly programmable and you will be able to set different mowing times and days according to your preferences.

In short, we would recommend the Gardena R80Li robotic lawn mower to environmentally conscious folks first and foremost. It also wouldn't disappoint those who are looking for a mower that is simple to operate without being underwhelming in terms of what it can bring to the table.

Husqvarna Automower 310

Free Movement Pattern

The Husqvarna Automower 310 isn't necessarily cheap but the model's price is justified considering what it is packing and how much it offers on just about every level. It is both the little things and huge changes that make the mower so much better compared to its already impressive predecessor.

We really like how balanced the control is. The mower is able to automatically detect any imbalances in the cutting system for that silent, trouble-free operation. We're talking about imbalances that could be caused by missing, double-mounted, or damaged blades.

The model's free movement pattern isn't necessarily new but it has been upgraded to an extent that you'll hardly have any issues keeping the lawn perfectly cut, giving you that beautiful carpet-like look.

Its razor-sharp blades are able to cut the grass gently from all and every direction, letting it grow strong afterward. Plus, this way, you'll also be able to effectively prevent moss growth.

In many ways, that uniform cutting result is possible thanks to the fact that the model lets you start the mowing process at three different remote locations along the patented guide wire, right out from the charging station. This is particularly important and helpful for larger lawns.

Review of Husqvarna Automower 310 Robotic Lawn Mower

Any Terrain Will Do

Another little detail that helps achieve that universal cutting result is the mower's automatic cutting functionality that excels at evening out the grass height differences. Its cutting disc sensors are able to detect when the mower enters an area with higher grass and switch the cutting technology to a systematic spiral pattern.

The high-resolution, medium-sized display with a graphic menu structure doesn't necessarily hurt too. The menu is straightforward and intuitive. Though the model is packing ample functionality, you shouldn't have any issues figuring them out. It might take you some time since there are so many little extra details here but probably not too much effort. Among other things, the model incorporates personal settings that will let you schedule the machine to mow at a specific time(s).

There are many components and features here that make the mower so universal and versatile. We've already covered a few but none matter as much as the model's construction. The seemingly low-profile design is actually able to handle slopes up to 45%. It has no problems with narrow passages.

Long story short, the Husqvarna Automower 310 builds upon its predecessors' successful implementations and is able to take that robotic mowing game to the next level. The machine is relatively lightweight and nimble but rugged and robust at the same time. It will be able to work under any weather conditions. Its performance and functionality are as good as it gets.

WORX WR140 Landroid M 20V

Comprehensive Algorithm

The WORX WR140 Landroid M is as affordable as robotic lawn mowers come. The model has its flaws compared to its more expensive peers but nothing that would prevent the machine from competing against these peers.

First and foremost, what we're dealing with here is an outside robot. It lives in your yard, rain or shine. Sure, the weather can get too harsh for its taste. That's when the robot automatically heads back to the charging station to wait out the storm. You don't have to direct the mower yourself nor do you have to worry about certain weather conditions damaging its components.

That being said, it all starts with the mobile app. You can use the company's proprietary application to adjust the mowing schedule and control the robot remotely.

The model's algorithm measures your yard using the lawn size calculator and suggests an automatic schedule based on your yard's size and overall conditions. Don't care for that schedule? You can always use the manual schedule feature to set the schedule according to your needs and preferences.

The application's intuitive layered interface is as accessible and straightforward as these things come. You'll have no issues figuring out the settings and controlling the robot in general. You can track the robot via GPS, set notifications, the usual deal.

Review of WORX WR140 Landroid M 20V Robotic Lawn Mower

Kid- and Pet-Friendly

As far as the model's performance is concerned, we don't have any major complaints. It is able to work for an hour straight and takes no more than 90 minutes to fully recharge.

The mower's blades are offset, letting the machine mow closer to your lawn’s border than ever before. The result is less grass to trim and more free time to enjoy.

At the same time, the robot can sense and bypass movement and will automatically turn off when it is picked up, making the mower pet- and kid-friendly.

The model's 7-inch cutting width is not necessarily impressive in general but it is more than sufficient considering that the mower is designed for small- to medium-sized lawns less than 0.25 acres. The cutting height ranges from 1.5 -to 3.1 inches, standard stuff that lets the mower handle short and tall grass alike.

All things considered, the WORX WR140 Landroid M offers an excellent price-performance ratio. The model does not trail behind its more expensive competition in just about every important regard. It will be able to keep any small/medium-sized lawn in the most pristine condition. You won't have to do anything yourself.

What Is a Robotic Lawn Mower?

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 lot 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.
