RoboUP RACCOON 2SE Test

Brief explanation: A robotic lawnmower without a boundary wire orients itself via satellite (RTK), laser (LiDAR) or camera with AI (VSLAM) – instead of via a wire in the ground. Which system is right for your garden depends primarily on size, obstacles and budget. Models such as the RoboUp Raccoon 2 SE demonstrate this: The entry-level cordless robotic mower is now available for under 500 euros – but not for every type of garden.

Why the boundary wire annoys so many people

Anyone who has ever installed a classic robotic mower knows the procedure: Laying the cable, hammering in pegs, neatly rounding corners, running the cable to the station and hoping that no animal tears out the wire. Depending on the size of the garden, it takes two to three hours of work. And when you first dig in the ground in spring? Bang, wire breakage, troubleshooting in the lawn.

Classic robotic mowers need a laid boundary wire; cordless models navigate by satellite or camera instead.

This is where wireless robotic lawn mowers come in. They navigate by satellite, laser or camera – without any underground infrastructure. This saves time during set-up and nerves over the entire service life. The market is growing correspondingly fast: by the 2026 season, there will be more cordless models available than ever before – from entry-level devices under 500 euros to professional mowers with all-wheel drive.

RTK, LiDAR or AI vision – what technology is behind it all?

Three navigation approaches dominate the market. Anyone buying should know the difference – because it determines whether the robot really works reliably in your garden.

RTK-GPS: Precision via satellite

RTK stands for “Real Time Kinematic” and is a particularly precise form of satellite navigation. While normal smartphone GPS can be off by several meters, RTK works with an additional reference station and is accurate to within a few centimeters. The robotic lawnmower therefore knows exactly where it is and follows clean, parallel paths. RTK is the most accurate option for large, open lawns.

Illustration: Mähroboter mit RTK-GPS, Referenzantenne im Garten und Satellitenverbindung
RTK-GPS combines satellite signals with a reference antenna in the garden and thus achieves accuracy in the centimeter range.

The catch: an antenna pole usually has to be set up in the garden, and dense tree canopies or tall houses can weaken the signal. The larger models in the RoboUp portfolio, such as the RoboUp T1200 Pro, rely on GPS-based navigation for much larger lawns. RTK models typically start in the high three- to four-digit range.

LiDAR: Laser scanner like an autonomous car

LiDAR (Light Detection and Ranging) emits invisible laser pulses and measures a precise 3D image of the surroundings from the time of flight – independently of satellite signals. LiDAR robotic lawnmowers navigate reliably even under trees, in cloudy conditions and in complex gardens. The price for this is significantly higher: the current entry-level model Mova 600 has an RRP of 999 euros, but is now available in stores for significantly less. Higher-quality models such as the Mova LIDAX Ultra 1000 AWD are priced above this.

LiDAR sensors create a precise 3D image of the garden environment – independent of satellite signals.

AI-Vision / VSLAM: Navigation by camera

The latest approach relies on cameras and AI. VSLAM (Visual Simultaneous Localization and Mapping) combines camera images with inertial sensors to map the environment and determine the robot’s position within it. AI algorithms also distinguish lawns from paths, beds or obstacles. The system does not require any expensive additional components – and is therefore significantly cheaper.

Illustration: Mähroboter mit KI-Kamera erkennt Zaun, Beet und Weg als visuelle Grenzen
AI vision systems recognize visual boundaries such as fences, beds or paths and navigate without boundary wires.

The price for this is that pure VSLAM systems need clearly recognizable boundaries. Fences, walls, paths, flower beds or lawn edges serve as visual anchors. It becomes difficult in open meadows without visible boundaries. Some top models therefore combine camera recognition with satellite navigation to compensate for the weaknesses of camera-only models – but this drives up the price.

Three navigation systems in direct comparison

Criterion RTK-GPS LiDAR AI vision / VSLAM
accuracy 2-5 cm cm-accurate, 3D depending on the garden
Works under trees limited works yes yes (with visual anchors)
Works in open areas without borders yes Yes no
Additional hardware required RTK antenna Sensor tower on the robot none
Typical price range (entry level) from approx. 999 euros from approx. 600 euros (RRP higher) from approx. 499 Euro
Example model RoboUp T1200 Pro Mova 600 RoboUp Raccoon 2 SE

Many current top models combine several technologies: RTK plus camera, LiDAR plus AI vision. This compensates for the weaknesses of individual systems, but drives up the price.

RoboUp Raccoon 2 SE: entry-level model for less than 500 euros

This is where the RoboUp Raccoon 2 SE comes in. Instead of RTK or LiDAR, it relies exclusively on VSLAM, an inertial navigation system (INS) and an AI camera for lawn detection. This explains the price: according to the manufacturer, the RRP is 629 euros, while the robot is currently listed in the official RoboUp store for around 499 euros. If you were an early bird, you could even get it for as little as 359 euros during the Kickstarter phase in fall 2025.

Who is the concept made for? For gardens with clear visual boundaries – fences, walls, lawn edges, flower beds or paved paths. The manufacturer specifies a maximum area of 600 m²; in practice, 500 m² is the realistic upper limit for daily mowing without loading breaks.

Set up in five steps

The Raccoon 2 SE is actually set up as quickly as RoboUp promises. In practice, it looks like this:

Infografik: Fünf Schritte zur Einrichtung eines Mähroboters ohne Begrenzungskabel
Setting up a cordless robotic lawnmower usually takes less than ten minutes.
  1. Position the charging station – level surface, socket within reach, hammer in pegs.
  2. Fit the bumper and mower blades – a screwdriver is included.
  3. Place the robot in the station and switch it on – the display guides you through the initial configuration.
  4. Start mapping – either automatically (the robot moves along the edge of the lawn independently) or manually via app remote control, which works more reliably in winding gardens.
  5. Connect mowing zones (optional) – lay out the enclosed marker disks for the front and back garden as a visual reference. Up to three zones are possible.

If you don’t want to use an app, press start on the device – the Raccoon then maps automatically and gets started. The app also provides schedules, app-controlled cutting height, spot mowing for heavily used areas and a remote control function. Practical tip: Manual mapping via the app clearly delivers better results in winding gardens than the automatic version – if you rely on the robot alone here, you may end up with untidy outer edges or wheel tracks in the bed. A detailed classification can be found in our practical test of the Raccoon 2 SE.

Where the Raccoon 2 SE shines – and where its limits are

The camera-based VSLAM system is significantly cheaper than RTK or LiDAR, but it requires good visual landmarks. In concrete terms:

Well suited for:

  • Gardens with fences, walls or clearly recognizable lawn edges
  • Areas framed by paths, flower beds or paving stones
  • Typical terraced house gardens or residential gardens up to 500 m²
  • Users who do not want complicated installation or an RTK antenna

Less suitable for:

  • Open lawns without visible boundaries – such as communal green spaces
  • Heavily shaded areas without other visual anchor points
  • Very large or complex gardens over 600 m²

For those who value the classic stripe pattern: RoboUp has now extended parallel mowing to the entire map via an OTA update. The Raccoon 2 SE now follows systematic paths across the entire lawn and automatically changes direction during mowing when it reaches the boundary. This creates the desired striped look in the grass without having to intervene manually at the edge. Alternatively, a random mode is still available, which allows the robot to move more freely over the area.

Which robotic mower suits which garden?

There are three questions to ask before making a purchase: How large is the area, how manageable is it and how much budget is available? This matrix helps with the pre-selection.

Garden size Boundaries clearly visible Open / few anchors Sloping / complex
up to 200 m² AI vision (e.g. Raccoon 2 SE) RTK beginner LiDAR model
200-500 m² AI vision or RTK beginner RTK LiDAR or RTK + camera
500-1.000 m² RTK + camera RTK LiDAR + AWD
over 1,000 m² RTK + camera, professional models RTK, professional models LiDAR + AWD, professional models

When is it worth switching from a wire model?

If you are already using a classic robotic lawnmower with a perimeter wire and are happy with it, there is no need to switch. The advantage of cordless systems is particularly evident with new purchases or if the old wire is causing problems anyway. Three points should then be put to the test:

Garden size and shape: for clearly defined areas up to 600 m², a camera system such as the Raccoon 2 SE is sufficient. For large, open or hilly gardens, RTK or LiDAR models are the better choice – such as the RoboUp T1200 Pro for large lawns or a LiDAR model like the Mova 600 for complex gardens. However, such devices cost many times more.

Setup effort: RTK systems are more precise, but require an antenna and more configuration. Pure camera models such as the Raccoon 2 SE are ready for operation in under ten minutes – but only if the garden is suitable for them.

Budget: Until recently, worthwhile robotic lawn mowers without a boundary wire started at 800 to 1,000 euros. Models such as the Raccoon 2 SE for 499 euros or LiDAR starters such as the Mova 600 break away from this price level. If you want more functions or larger areas, you should plan on spending 1,000 euros or more.

Conclusion: Cordless mowing will no longer be a niche technology in 2026

In 2026, robotic lawn mowers without a boundary wire will have arrived on the mass market. The question is no longer whether, but which system suits your garden. RTK is convincing in large, open areas. LiDAR scores points in complex or shaded gardens. AI vision, as with the RoboUp Raccoon 2 SE, is the cheapest option – as long as the garden has clear boundaries.

For owners of small to medium-sized home gardens with fences, beds or paved paths, the Raccoon 2 SE is a serious proposition for around 499 euros. No cable, no antenna, quick set-up, quiet operation and an app that doesn’t get in the way. Those who maintain larger or open areas are better off planning an RTK or LiDAR solution – and the corresponding budget at the same time.

Frequently asked questions about the robotic lawnmower without boundary wire

Which is the best robotic lawnmower without a boundary wire?

There is no single answer – the best model depends on the garden. In clearly demarcated gardens of up to 500 m², AI Vision models such as the RoboUp Raccoon 2 SE impress with their simplicity and price. For larger or more complex areas, it is worth looking at GPS or LiDAR models. A comprehensive selection across all price ranges can be found in our 2026 robot mower best list.

What are the disadvantages of a robotic lawnmower without a boundary wire?

Three points regularly stand out: Firstly, camera models reach their limits in open areas without visual anchors. Secondly, the edge mowing performance is often weaker than with wire models – depending on the device, strips remain at the edge that have to be reworked. Thirdly, obstacle detection varies significantly between the models, especially in the case of small obstacles or plants.

How much does a good robotic lawnmower without a boundary wire cost?

The price range is much wider in 2026 than it was a year ago. Entry-level models with AI vision such as the Raccoon 2 SE start at around 499 euros. LiDAR robotic lawn mowers start at around 600 euros street price with an RRP of around 999 euros. RTK models for medium-sized gardens cost between 999 and 1,500 euros. Professional devices for large or hilly areas are priced at 2,000 euros and more.

How safe are robotic lawn mowers without a boundary wire?

Safety depends heavily on the sensor system installed. Models with an AI camera generally detect people, animals and objects reliably and stop in good time. In addition, bumper sensors, a lift stop and ideally a night mode to protect hedgehogs and the like should be available. If you have children or pets in the garden, you should pay particular attention to the safety features before buying.

Robotic mowers without a boundary wire for small areas – does it make sense?

Yes, small gardens in particular benefit. For areas of less than 200 m², laying a wire is hardly worthwhile and setting up an RTK system seems oversized. AI Vision models such as the Raccoon 2 SE are ready to go in under ten minutes and are cost-effective. The prerequisite remains: The garden must have clear visual boundaries.
