Gardena 19113-28

A True Champion Among Robotic Grass Trimmers

When regular lawn mowing solutions just don’t cut it anymore you may want to be one step ahead. Fortunately enough, this self-sustainable device from Gardena makes other robotic lawn mowers pale in comparison.

First of all, with a weight of only 8 kg, the unit is fairly stable on the lawn and can be utilised in almost any weather as long as it is not freezing outside. The housing, on the other hand, is made of high-impact waterproof plastic that won’t let a single raindrop get to the electric components of the machine. And so, you don’t have to worry about maintenance aside from occasional dirt cleaning. On top of that, the treaded wheels of the lawn mower allow it to traverse freely without risk of sliding down the slopes, which is great for cutting grass covered in dew or right after it rained outside.

For your convenience, the kit comes equipped with an automatic charging system, which enables the lawn mower to recharge on its own when it is running low on batteries. The whole process will take only 60 minutes and after the unit is done it will get back to cutting your lawn for up to 65 minutes straight, before returning to its parking lot. In addition to a handy charging dock, the package also comes equipped with a 200-metre border wire. Thanks to this attachment you can actually set the borders for the mowing area so the robot will avoid the area beyond them.

Review of Gardena 19113-28 Robotic Lawnmower for Lawn Areas of Up to 750 m sq

Won't Get Lost Regardless of Terrain Difficulty

The self-driving capabilities of the Gardena 19113-28 allow it to easily find the lawn parts that the lawn cutter has missed so you don’t have to worry about the lawn being cut unevenly. Alternatively, the sensor system won’t let the appliance stroll too far away from the docking station. Moreover, the collision, tilt, and lift sensors also provide the lawn mower with additional safety measures so it won’t fall on the side or rollover accidentally.

Speaking of slopes, the combination of two front and one rear wheel allows the unit to drive on uneven ground. What makes this model stand out is its ability to drive and cut hard grass on slopes with an angle of up to 16.7°, making it great for most tasks regarding your lawn.

The adjustment capabilities of this mobile grass cutter allow choosing the required cutting length, various mowing modes, as well as the frequency at which the robot will mow your lawn.

In the end, the Gardena automatic lawn mower is, perhaps, the best model for its price around. The combination of high-quality build and reliability makes this low-maintenance gadget a real steal for owners of rather large lawns.

Flymo 1200R

Avoids Obstacles and Pets

If you have pets or small children, you’re likely to be very worried about the safety of using a robotic lawn mower, afraid that the animal or your toddler might get hurt or damage the equipment. However, the Flymo 1200R won't hurt anyone and the likelihood of it being broken is incredibly small.

First off, this model has been designed with a broader distance between the edges of the casing and the blades, so there is no chance of a child touching the machine and being cut by a blade that pokes out. Plus, if the kid or a bigger pet decides to turn the appliance over, the blades will stop spinning automatically and won’t be able to hurt them.

There is also no chance of the lawnmower bumping into anybody on its path as a special obstruction sensor will detect people or animals on its path and veer away to prevent a collision.

The only part that might become a target of a curious tot or a rowdy dog is the docking station. It’s painted in bright, attractive colours, so you might consider repainting it to stop your child from trying to play with it.

Plus, you don’t have to worry about the machine disturbing your child’s sleep, as it only emits 58 dB of noise, no louder than a quiet conversation. You could even run this appliance with your windows open without hearing it from the comfort of your bed.

Review of Flymo 1200R Lithium-Ion Robotic Lawnmower

Automatised and Efficient

Able to traverse slopes of up to 14°, the Flymo 1200R is not afraid of unkempt or bumpy gardens. The sharp blades beneath can cut grass in the area of 30 square metres per hour, working on up to 400 square metres in total. Just let the machine run through the night and you will see a well-trimmed lawn in the morning without being disturbed by any noise or having to get up and take the mower to the docking station. The recharging occurs automatically after the appliance operates for about 65 minutes. The charge time is around 50 minutes, an admirable number that is up to par with industry leaders.

Flymo also mows in an irregular pattern without any need to program it. This is done so that no areas are missed, which might happen with machines that strictly patrol the perimeter in straight lines. Plus, this model mulches on the way, utilising clippings to provide nutrients for new plants.

All in all, the highly sensitive collision sensor makes the Flymo 1200R safe and its variety of perfected features makes it a wonderful choice for households with smaller gardens. Weighing in at 7.4 kg, the machine is so lightweight that you can easily carry it in your hands or store in your garden storage if a storm occurs or you just want to let your grass grow out for a bit.

McCulloch ROB 1000

A Silent Robot

The McCulloch ROB 1000 is a pretty solid model that has quite a lot going for it. It doesn't lose to any model in its price category in terms of performance, all of the necessary features are there, and the price is more than fair. But if we had to point out the best thing about it, it would probably have to be the fact that this machine is virtually silent. The majority of robotic mowers produce a fair share of noise which can disturb the people around you as well as prevent you from enjoying a nice quiet lazy Sunday afternoon. That isn't the case with ROB 1000. On the contrary, the model produces so little noise that you can even use it at night without having to deal with complaints from your neighbours. And while we're still on the subject of noise, this remote lawn mower comes equipped with an audible alarm that will protect it from theft.

With that out of the way, it is time to talk about performance. Performance-wise, it certainly isn't the most powerful option on the market but it gets the job done. And given how much the people behind this product are charging for it, what the model is capable of delivering is actually quite impressive. It offers 65 minutes of runtime and it takes the mower only about 50 minutes to fully recharge. That should be enough to cover up to a quarter of an acre, meaning it will be able to handle your average lawn with effortless ease.

Review of McCulloch ROB 1000

The Ability to Adapt

Now that we have already mentioned the alarm, we thought it wouldn't hurt to talk about a few other features that this model comes equipped with. First off, we didn't say that bit about using this mower at night just for the sake of it. Since this model is fully programmable, you can tell it exactly how and when you want the robot to mow your lawn. Of course, we already said enough about when and, as for the how, this robotic assistant was created with the ability to adapt to a number of different surfaces, implementing a solution that cuts the grass in an irregular pattern, thus leaving your lawn looking clean and pristine, without uneven areas or track line markers.

In case you feel like the alarm wouldn't be enough to protect this little investment, the manufacturers also made sure to equip this robotic lawn mower with a PIN code so that nobody would be able to access it but you and the people that you shared the code with. To somewhat rephrase our earlier point, the McCulloch ROB 1000 will prove to be a pretty good fit for your average customer as it is one of the cheaper options on the market despite the fact that it offers solid performance and all of the necessary features are there.

WORX WR130E S300

A High-Performing Budget Robo-Trimmer

Even though most robotic lawn trimmers are quite sophisticated they often lack that customizable touch to them that would allow the user to adjust the mowing process according to their needs.

In case you already have one of the power tools from WORX you will be pleasantly surprised to know that this lawn mower is backwards compatible with any 20V battery from the company’s line of cordless tools.

As for the charging of the unit’s base battery, the device comes with a small docking station. Thanks to its compact size it is barely visible when mounted on a wall, so you won’t have issues with the station sticking out too much. Once charged, the device can cut your lawn for up to 60 minutes straight, making this model’s autonomous runtime one of the best in its class. To ease the installation process the charging base is equipped with 8 nails allowing you to firmly secure it. In order for the unit to find it’s parking spot, we recommend placing the docking station in close vicinity of the lawn. This way the robot will easily find its charging spot and won’t stroll too far away.

The only thing that did bother us, though, is the initial setup process, which requires some effort since it is not an actual, ready out-of-the-box robotic lawn mower. However, once the unit is configured you won’t have any issues with it, as long as its blades are sharp.

Review of WORX WR130E S300 Landroid Robotic Mower

The Best Thing That Can Happen to Your Lawn

Design features out of the way, let’s take a closer look at the specifications of this device. When it comes to actual lawn mowing, the high-quality blades of the device can accurately trim the grass from 50 to 20 mm, depending on the mode you have picked. Speaking of control functions, the unit can be controlled either via a mobile application or using simple voice commands. Alternatively, if you need to turn the unit fast you can do so by pressing the big red STOP button located on top of the grass cutter’s housing.

In addition to an already great package of features, the lawn mower also features 150 metres of special wire that will help you in setting the borders for the unit to operate within. The total coverage area, on the other hand, is 300 square metres, which should suffice most lawn layouts out there. Nevertheless, if you find these numbers rather unimpressive there are also two other models from WORX optionally available that can cover 700 and 1500 square metre areas, respectively.

All things considered, thanks to its superior build quality and a huge array of additional features, the WORX WR130E is, perhaps, one of the top robotic lawn mowers in the medium-price range available today.

Robomow RC304

Low-Profile Automatic Grass Trimmer

The Robomow RC304 may not look like something special at first glance, however, it is one of the simplest models to use among similar products in the same price range. Owing to its unique design and a peculiar wheel configuration, the Robomow RC304 can cover slopes with 36% incline (20°), which is simply amazing, considering that other similar models can only cut grass on slopes of only 14°, on average. On top of that, its cutting width of 28 cm allows covering wider areas in one go, saving both time and battery charge.

Speaking of charging, the device comes with a generic charging station and a battery that can be charged in about 60 minutes. After it is fully charged, the robot will be able to operate on its own for about an hour before it has to come back to its little parking spot.

Moving on, the SmartMow feature improves the robot’s navigation capabilities, allowing it to find the spots it had missed during previous runs as well as locating its charging station with relative ease. The only thing you have to worry about is leaving the space in front of the station clear at all times so the robot can park safely.

But what about the actual maintenance? Fortunately, the device is fairly simple in its design so it is quite easy to open when you need to clean the excessive grass build-ups inside. Moreover, since the lawn mower has a triangle-shaped blade it doesn’t require a tech-savvy person to switch. So if the blade gets dull over time, simply detach it and install a new one in a few simple motions.

Review of Robomow RC304 Automatic Mower Premium

A Premium Model in a Compact Package

Once the borders are set (using the provided wires), the unit is capable of covering areas of up to 500 square metres in size, which is simply stunning, considering the relatively small price tag for the whole kit compared to similar packages. The cutting blades or, in this case, one blade does its job surprisingly well by trimming grass down from 60 to 15 mm, depending on the settings you’ve picked.

To help the robot reach the desired results you can use a handy mobile application that helps in adjusting the cutting program. With just a few taps on the screen, you can set the area for the lawn mower to cut, the required cutting height as well as the time span in which the robot will operate while you are away.

Wrapping things up, we recommend the Robomow RC304 to owners of medium- to large-sized lawns. Smart, highly autonomous, and requiring little to no maintenance, this robotic lawn mower does pretty much everything you could expect from a premium device but only at a fraction of its price.

What Is a Robotic Lawn Mower?

A robot lawn mower is exactly what the name says. It's a battery-powered automated robot that moves around on wheels and trims grass with razor blades. Such mowers come with a docking station, used for recharging, and a special perimeter wire for setting boundaries of the area that needs to be trimmed. Some models may have a solar battery which prolongs the operation time. Many of them allow for an option to program a mowing schedule and on top of the mentioned features may offer some more extras facilitating their use. 

The advantage to using a robot lawn mower is that it is completely autonomous, which means, a human intervention is not required. All you need to do is prepare the yard, define the borders, lay the wire, set the schedule of mowing, and connect a docking station to the power supply. Once that's done, the machine will mow the grass for you allowing you to concentrate on other things or tasks that need to be done. Unlike some mowers, robot lawn mowers do not collect the cut grass but shed it aside on the ground so it can serve as a natural soil fertilizer unless you decide to pick it up yourself. 

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 200 square metres, while others may patrol as much as over a square kilometre. 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 a device with a lot of metal parts, staying on the flat lawn, may attract the lightning strike. So, when the rain sensor detects a 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 a specific time of a day. Some of them may have an option to set the password for controls or configure different behaviour 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 spiralling 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.

Did you know?

Your Lawn Is Bigger Than You Think

  • An average lawn will contain about 850 grass plants per square metre. This equals around 3000 blades of grass, all of which need nourishment and care.

  • Grass grows somewhere around 7 cm per month. Leave your yard alone for the summer and soon you’ll have to find your pets by sound only as the plants will be higher than them!

  • The average size of a lawn is around 800 square metres. More than sufficient to tire you out but not nearly large enough to stop a good automatic lawnmower.

  • Nearly 60 million kilograms of fertilizers and pesticides are applied to lawns worldwide every year.

  • A well-maintained yard with healthy grass can raise the value of your property by as much as 20%.

  • That grass patch in your yard? It produces three times as much oxygen as a tree, the plants are just that efficient.

The Best Way to Take Care of Your Yard

  • If you think that you’re the first person to hate taking care of a lawn, you might be surprised to find just how long ago this chore started. The first-ever publication on lawn care, a whole book, in fact, was published back in 1870.

  • Homeowners spend from 5 to 8 days per year taking care of their yards. Makes sense to speed up the process, right?

  • More than 22 million homeowners use professional services for yard maintenance. Unless you want to add that to your monthly expenses, the easiest alternative is to read a robotic lawn mower review like ours and find something to help you.

  • More than 6000 people are hospitalised every year after falling off ride-on mowers or after a regular one malfunctioned. Yet another point in favour of automatised appliances and an important reminder to take safety precautions.

  • A robot lawn mower, in comparison with a regular one, is 60% more efficient and much easier to use. Studies are still being done on exactly how much safer it is but even now it’s clear that regular models are more likely to cause trouble.

  • There are nearly 150 million lawnmowers being used worldwide, with a third of them located in the United States.

  • If you’re ever travelling by Merseyside, you can drop by their British Lawnmower Museum. Care to guess what’s on display?

  • Before we were blessed with the invention of lawn mowers, our ancestors had to cut grass using scythes or… sheep! The livestock ate enough grass to keep yards well-maintained without the need to stand out in the heat with a scythe all day long. How lucky are we to have the automatic lawn mower?

  • If you somehow have a passion for lawn maintenance, you could go to the USA and get a degree in that subject from Penn State University. Of course, the actual studies are more complicated than simple care for grass, but the foundation is exactly that.

  • Garden gnomes may be fashionable right now, but the most popular ornament is considered to be the pink flamingo with a quarter of a million sold every year. A good time to invest perhaps?

Thirsty Plants

  • Water makes up 80% of the weight of a single blade of grass.

  • Around 50% of water used in British homes is used to water lawns.

  • Lawns absorb 6 times as much water as a whole field of wheat, on average. So taking care of your grass is essential to preserve water.

  • The famous AstroTurf was invented back in 1967, making life easier for the many people that wanted a patch of grass in their yard but were reluctant to spend time on maintenance. No longer did you have to spend litres of water on a small grass patch. And, of course, it changed the way football fields were designed and serviced.

FAQ:

Q: I’ve received my automatic lawn mower, can I start using it right away?

A: No, first you have to do a one-time but very important procedure. Using the specialised wire included with your product, define the perimeter in which the machine can operate. You can put it underground, but not too deep though. The reason why you need to do this is that it establishes a sort of electronic invisible fence which tells the appliance where it must stay. If you set it up properly, the lawnmower will work efficiently inside the bounds you’ve set and never leave them. This is a long task that can take up several hours, but you only have to do it once and it’s essential for the device to function. If you don’t set up the wire, the appliance might just ride away without proper instructions.

Q: What can I do to keep my pets and kids safe when this mower is in operation?

A: Don’t be afraid of them getting harmed, most machines of this kind are either programmed to drive around obstacles or have their own safeguards to keep curious children and animals away from the blades. And if you have a sufficiently quiet lawnmower, you can simply run it while your toddler naps. These devices do not require any precautions that regular ones wouldn’t.

Q: I’ve had my regular mower get clogged or “throw” objects such as rocks away by hitting them with blades. Is there any danger of that happening with these models?

A: Since blades on robotic lawnmowers are rather small and placed quite densely, an object would have to be rather tiny to get trapped between them. That way a clog or a stray rock flying off to hit someone is very unlikely. Just make sure to look over your appliance once in a while to make sure nothing is stuck to the blades or between them.

Q: Is there any specific reason why cutting grass with automatic lawnmowers is better than regular ones, aside from convenience and safety?

A: The cutting method utilised by these appliances is different than the one in the non-automatised models. They only shave off small pieces of grass, which leaves the lawn even and clean but not too short so that it looks unkempt. Plus, you won’t have to clean up afterwards as these small pieces can serve as a soil fertiliser.

Q: Will I have to take the lawnmower to the charging station myself?

A: Most likely, not. The majority of models have a setting that tells them to ride around the perimeter until they reach the vicinity of the docking port. Then the machine will approach it and start charging automatically. Some of the more advanced models also have an extra wire, like the one you lay around the perimeter to set the bounds. However, that additional wire is used not to restrict the appliance but to guide it straight to the charging port. You lay it from the working area all the way to the charger and the machine follows it to reach its destination.

Q: Can I use basic batteries to run this appliance?

A: No, this type of lawnmower charges at a special docking station, no need for any other accessories. Perhaps you might find one that takes batteries but it’s prudent to use a standard model that utilises a charging station.
