Robotic lawn mowers conquer the gardens. But which one is the right one? The large lawn mower robot test overview has identified the best lawn robots in the main categories. The trend is towards stronger and smart robotic lawn mowers such as the new GARDENA smart SILENO life range or the new Worx Landroid M WR141E and Landroid M WR151E prove. With our recommendations for the best lawn mower robot with App operation, lawn edge mowing function, for large, medium and small lawns as well as lawn robots without boundary wire, the purchase of a lawn mower robot becomes a success. In addition, we offer an overview of favourable offers for the respective lawn mower robot recommendation and provide answers to burning questions on the subject of robotic lawn mowers in our Mähroboter FAQ. If you are about to make a purchase, you will find valuable tips in our lawn mower robot purchase advice.

GARDENA smart SILENO city Set – Price-performance recommendation

We recommend the GARDENA smart SILENO city Set as the best lawn mower robot in our comparison. The intelligent lawn mower robot has lawn areas of up to 500 square meters, which should be sufficient for most gardens, works reliably and ensures a beautiful lawn cut. The well-equipped lawn mower robot comes as a set with a gateway, can be conveniently operated via an app and can also be integrated into the Gardena smart system. This makes the GARDENA lawn robot very suitable for most applications.

Lawn mower robot with App control: Recommendation GARDENA smart SILENO city Set

gardena-smart-city-set

With the GARDENA smart SILENO city Set, garden tool manufacturer GARDENA has landed a real hit. The lawn mower robot from the SILENO city series differs from the other intelligent robotic lawn mowers of the city series in several ways: It comes as a set with the GARDENA Gateway, which communicates with the GARDENA smart app (iOS|Android). The gateway, which is installed outdoors, ensures good communication coverage and simultaneously integrates GARDENA smart SILENO city Set into the GARDENA smart system, which can be used to operate other smart garden tools. For example, the mowing times can be coordinated with the irrigation times of the smart GARDENA irrigation system via an app. The concept is convincing and helps the lawn mower robot to make our recommendation.

The intelligent GARDENA smart SILENO city Set lawn mower also impresses with its excellent performance data. It maintains gardens with a working area of up to 500 square meters, is the quietest machine in our lawn mower robot comparison with 58 dB(A) and has a PIN code anti-theft device. In contrast to other devices, no rain sensor is integrated, so the GARDENA smart SILENO city Set continues to mow even in the rain, which doesn’t bother it, but pollutes the housing with grass cuttings. However, cleaning the lawn mower robot is also easy – it is sufficient to spray the lawn robot with the garden hose. One advantage of the App-supported robotic lawn mowers is that if, for example, you are at work and learn from the App that a storm is brewing at the location of the GARDENA Gateway, the lawn mower robot can be ordered to the charging station. In conjunction with a lawn mower robot garage, the device is then in good hands.

Robot lawn mower with lawn edge mowing function: recommendation Worx Landroid SO500i

worx-landroid-so500i

The Worx Landroid SO500i is an affordable model that compares well with the GARDENA smart SILENO city set. With an RRP of just under 750 euros, it undercuts the GARDENA model by 350 euros. The intelligent lawnmower robot is also designed for work surfaces of up to 500 square meters and has app control. However, the app is not connected via its own gateway, but via WLAN. In such a case, it is advisable to check the WLAN coverage at home with the smartphone in the garden. If the lawn mower robot moves away from the radio coverage, the user has to wait until the random mowing tracks bring the Worx Landroid SO500i back into reach. As the only model in our lawn mower robot comparison, the intelligent lawn mower robot of the Chinese gardening tool professional offers a lawn edge mowing function. Worx has attached the mower to the side so that the blades can cut close to the edge of the lawn. By pressing the Home button, the Worx Landroid SO500i (WR105SI) is instructed, for example, to mow only along the edge of the lawn. However, the lateral mounting of the mower also reduces the safety area to the blades.

A negative feature of the Worx Landroid is the missing PIN code anti-theft device that the GARDENA has. In addition, the Worx Landroid SO500i has no display on the device, programming is done exclusively via App. Since the lawn mower robot is delivered pre-programmed, it can be operated out-of-the-box – without an app, however, the user cannot make any subsequent changes. The Worx lawn mower robot is equipped with a rain sensor as it does not mow in the rain and then withdraws to the charging station. Those who value well-kept lawn edges and are looking for an inexpensive app-controlled lawn mower robot for gardens up to 500 square meters will find the Worx Landroid SO500i, a well-equipped lawn mower robot that is, however, somewhat sensitive and lacks display device operation on the machine. Apart from the lawn edge function, the GARDENA smart SILENO city Set leaves a better impression.

Robotic lawn mower without boundary wire: recommendation Wiper ECO Blitz 2.0

wiper-eco-blitz-2

Most robotic lawn mowers work with a boundary wire – this means that a cable must be laid around the working area of the lawn mower robot before it can be put into operation, which acts as a fence. Those who do not like this can use the Wiper ECO Blitz 2.0 lawn mower robot, our recommendation as the best lawn mower robot without boundary wire. Since the lawn mower robot cannot orient itself on a low-voltage boundary wire here, the Wiper ECO Blitz 2.0 uses six sensors for grass detection. In practice, this means that the wiper reverses as soon as it encounters an untreated area wider than 10 centimeters. These include, for example, floor slabs, tiles or mulch strips. Another orientation feature are obstacles such as garden fences, house walls or trees. Shock sensors allow the wiper to turn when it collides with an obstacle. This means that even with robotic lawn mowers without boundary fences such as the Wiper ECO Blitz 2.0, it is necessary to make the garden suitable for robotic lawn mowers. To be on the safe side – for example, if a pool is installed in the garden – we recommend installing small decorative fences or palisades as natural “bumpers” around the areas that the lawn mower robot is to drive around.

The Wiper ECO Blitz 2.0 is particularly suitable for less complex gardens, i.e. lawns without many bottlenecks or obstacles. When fully charged, the lawn mower robot, which does not need a boundary wire, mows autonomously. As with all other robotic lawn mowers, the mowing paths are selected at random in the overview. A lamp on the top provides information about the battery status. If this is weak or empty, the robot simply stops and has to be carried to the mains connection and recharged – a shortcoming, because this means that you always have to look for the battery charge level of the Wiper ECO Blitz 2.0, then carry it to its power supply unit if necessary, and after recharging it has to be left in the garden again. Here, robotic lawn mowers with boundary wire automatically make their way to their charging station and charge themselves automatically. The Wiper ECO Blitz 2.0 therefore needs more attention, but does its job reliably and under optimum conditions creates gradients of up to 50 percent, a top value among all the intelligent lawnmower robots presented in our comparison. With an RRP of just under 1,550 euros and a recommended working surface of 400 square meters, the Wiper is around 500 euros above our favourite GARDENA smart Sileno city set. If you don’t dare to lay a boundary wire yourself, you might consider using a service provider for this money. Unfortunately, as with the WORX lawn mower robot, the Wiper BLITZ 2.0 also lacks PIN code protection, so that thieves can use the device on foreign lawn terrain.

Lawn mower robot for large gardens: recommendation Viking iMow 632 / C

viking-imow-632-c

If you own a large garden with 1,000 square meters and more, you can breathe a sigh of relief and hand over the lawn mowing to the Viking iMow 632 / C lawn mower robot. The alternative of hiring a gardener or maintaining one or more goats is therefore a thing of the past. The Viking iMow 632 / C lawn mower robot is one of those robotic lawn mowers that work with a boundary wire. The long-distance mower creates working areas of up to 3,000 square meters, achieving optimum results with a working area of up to 1,000 square meters. One of the reasons for this is that robotic lawn mowers have to repeatedly return to their charging stations to recharge the battery when working on large areas. Our lawn mower robot recommendation for large gardens copes with gradients of up to 45 percent without it tipping over or immediately approaching the mountain without getting any further. Thanks to this good climbing ability, the Viking is also suitable for slopes. The height of the lawn cut can be varied from 20 to 60 mm. As a rule, you start with the highest cutting height and then reduce it downwards – if desired. The lawn mower robot then continuously prunes the stalks back to the set cutting height. The fine pruning sinks to the ground and becomes natural lawn mulch. Like all other robotic lawn mowers, the Viking iMow Mi 632 / C works out the mowing pattern at random.

The Viking iMow 632 / C feels at home in large gardens. It mows in any weather and has a rain sensor that can be activated and deactivated. The Viking iMow 632 / C model is operated via a removable display, which is very convenient and eliminates the need for the lawn mower robot to kneel down to program the mowing times. With the Viking iMow 632 C model variant, a smartphone app is also available. Just like the HUSQVARNA, the Viking also has GPS. This allows the lawnmower robot to be located via smartphone, which serves as an anti-theft device and is also fun if you simply want to see where the Viking is mowing in the garden. On the other hand, the Viking iMow 632 C uses its GPS system for zone management. This allows up to four mowing zones to be defined, on which the Viking then places mowing centers as desired.

Lawn mower robot with GPS: recommendation HUSQVARNA AUTOMOWER 450X

HUSQVARNA AUTOMOWER 450X

The HUSQVARNA AUTOMOWER 450X is the top model in HUSQVARNA’s X Series and is aimed at owners of large gardens and meadows of up to 5,000 square meters – one reason why the device has GPS supported navigation. In addition, the built-in GPS also provides tracking in the event of theft. Another special feature of the GPS lawn mower robot is that it is the only intelligent lawn mower in the best comparison to have an ultrasonic sensor for object recognition. It therefore does not have to hit an obstacle to change its direction of mowing, even though collision sensors are also on board the GPS lawn mower robot. The lawn mower robot therefore leaves nothing to be desired in terms of equipment.

The GPS module records the working area inside the boundary wire. This means that the lawn mower robot can use GPS to record exactly which areas it has already mowed and adapt its mowing pattern accordingly. As a result, the HUSQVARNA AUTOMOWER 450X provides the user with a perfect lawn cut that leaves virtually nothing to be desired. Using the AUTOMOWER CONNECT equipment, the owner can also control the lawn mower robot with GPS via a smartphone app and thus instruct it to stop, start or park. Together with the GPS module, the owner can also find out where the HUSQVARNA AUTOMOWER 450X is at any time in the event of a theft.

Test overview of robotic lawn mowers

The purchase of a lawn mower robot needs to be well considered in advance, because the purchase is always a small investment. The intelligent lawnmower robots in our comparison start with recommended retail prices from 750 dollars. Dealers sell the machines at much lower prices. We have considered the following criteria for you in our comparison:

  • Lawn cut pattern: Does the lawn mower robot mow the lawn evenly, or are mowing paths visible on the lawn? The robotic lawn mowers in our comparison all draw their mowing tracks at random, which is why they all deliver a very good result.
  • Garden size: The available lawn mower robot models are designed for different garden sizes. Generally, a distinction is made between robotic lawn mowers for small gardens up to 500 square meters and robotic lawn mowers for large gardens up to 1,000 square meters. We recommend the GARDENA smart SILENO city for small gardens and the Viking iMow 632 for large gardens.
  • App control: Although robotic lawn mowers work autonomously, control via an app is more convenient when it comes to programming mowing times, for example. Without an app, this usually has to be done directly on the display of the lawn mower robot. The GARDENA smart SILENO city is the best lawn mower robot with App control in comparison.
  • Lawn edge mowing function: As the mower unit is usually located in the middle of the lawn mower robot, blades of grass at the edge of the working area generally remain unmown and have to be cut by hand afterwards. The Worx Landroid SO500i lawn mower robot presented by us is the only one that offers a lawn edge function here.
  • Boundary wire: Most robotic lawn mowers work with a boundary wire that defines the working area of the lawn mower robot like a fence. With the exception of HUSQVARNA, all manufacturers provide sufficient installation material. Installation is not difficult, but involves a one-off effort: A cable must be pulled around the lawn and tapped with pegs into the lawn. robotic lawn mowers without boundary wire are based on traditional “delimiters” such as fences or tiles. Preparations are also necessary for these robotic lawn mowers, such as the attachment of decorative palisades as stoppers. The editorial board recommends the Wiper ECO Blitz 2.0 for robotic lawn mowers without boundary wire.
  • Price: The robotic lawn mowers from our comparison cost between 750 and 4,100 dollars. Our recommended lawn mower robot, the GARDENA smart SILENO city, costs around 900 dollars. Only the Worx Landroid SO500i is cheaper.
