Lymow One Plus evaluation: A tank-like robotic mower constructed for tough yards

Finest Costs In the present day: Lymow One Plus

Robotic mowers with out boundary wires have lengthy been customary, however the Lymow One Plus takes a radically completely different strategy. As a substitute of wheels and a compact design, the producer has opted for caterpillar tracks, a front-mounted twin reducing deck, and excessive engine energy. We examined the system on hilly, uneven terrain and checked whether or not the tank-like look is extra than simply advertising hype. Right here’s what we discovered.

Lymow One Plus: Design and construct high quality

The supply bundle weighs in at round 103 kilos. The contents are intensive and embrace mounting {hardware} for each soil and concrete in addition to the charging station and RTK antenna. The consumer handbook is multilingual.

As soon as unpacked, the robotic could be moved by a robust grownup due to the aspect carrying handles and its rear-heavy middle of gravity.

Visually, the Lymow is extra paying homage to a building web site car than a conventional backyard helper. Broad tracks, a front-mounted mowing deck, and the digital camera tower characterize its look.

The low middle of gravity and broad observe width enhance off-road functionality. The front-mounted mower deck additionally reaches areas the place the central blade discs of many rivals fail.

The chassis and mower suspension are manufactured from high-strength metal and a body of A380 die-cast aluminum, respectively. All connections, wheel suspensions, and the electrical peak adjustment are generously dimensioned. The development seems stable and torsion-resistant.

The movable mowing head is linked to the principle chassis through two highly effective springs and joints and follows the terrain independently of the robotic physique.

The IPX6 safety ranking permits the unit to be hosed down with a backyard hose. The working temperature vary is 14 to 113 Fahrenheit.

Lymow One Plus: Options

On the coronary heart of the machine is the LYCUT 2.0 mower deck. Two rotating blade discs manufactured from SK5 device metal with a hardness of fifty HRC function at as much as 6,000 revolutions per minute.

The reducing width is a powerful 15.7 inches, and the reducing peak could be adjusted electrically between 1.2 and three.9 inches. The strong metal blades are extra paying homage to traditional lawnmowers than typical robotic mower blades. Even tall or dense grass barely fazes the mower deck. The mower motor’s peak energy is 1,785 watts, with a rated energy of 680 watts.

Energy is transmitted through two broad rubber tracks with a deep-tread sample. They distribute the load over a big contact space and guarantee traction on moist, sandy, or free floor.

Lymow specifies a most climbing capacity of 100% or 45 levels. In our check, the robotic reliably dealt with gradients of as much as round 30 levels. The robotic can drive over obstacles as much as seven centimeters excessive. Turning maneuvers depart no seen marks on the turf as a result of each tracks can rotate in reverse instructions and the broad contact floor reduces strain.

The Lymow One Plus combines a number of programs for navigation. RTK satellite tv for pc positioning ensures centimeter-accurate positioning, with an exterior antenna offering the correction knowledge. VSLAM additionally comes into play, i.e. visible localization through the 2 entrance cameras. If the robotic quickly loses the RTK sign, it might probably proceed mowing autonomously for round 100 to 150 sq. meters or ten minutes.

Impediment detection is dealt with by an AI digital camera, 5 ultrasonic sensors, and two Corridor sensors for edge detection. Two LEDs on the tower illuminate the realm in entrance of the robotic in low-light circumstances, enabling night-time operation.

Energy is equipped by a LiFePO4 battery with a capability of 15 Ah at a nominal voltage of 35.2 volts. This corresponds to round 528 Wh. This battery know-how is taken into account to be considerably extra sturdy and thermally steady than standard lithium-ion cells. Lymow quotes 2,000 cost cycles at 80 % remaining capability. The battery prices in round 90 minutes utilizing the 405-watt quick charger. A single battery cost is ample for as much as 2,300 sq. meters. The robotic can cowl as much as 7,000 sq. meters per day.

The system provides loads of connectivity: Bluetooth, Wi-Fi, and 4G cell are built-in. A SIM card for 4G is included and can be utilized freed from cost for the primary yr.

As much as 80 mowing zones and maps protecting a complete of 60,000 sq. meters could be saved. Additionally on board: a rain sensor, elevate sensor, anti-theft safety with geofencing alerts, and a stay feed from the entrance digital camera through the app.

Lymow One Plus: Arrange

Set-up is extra complicated than with many LiDAR robotic mowers. First, an acceptable location for the charging station have to be discovered. In entrance of the station, there ought to be an obstacle-free space roughly three meters broad and 1.5 meters deep, with the bottom as degree as doable. The bottom anchors or enlargement bolts equipped safe the station relying on the floor.

Inserting the RTK antenna is extra tough. It wants a transparent view of the sky, so no dense tree cover or excessive partitions within the fast neighborhood. The equipped mast could be assembled from a number of segments and both anchored within the floor or mounted on a façade or shed utilizing a wall bracket. The connection cable to the charging station is ten meters lengthy. Alternatively, the included energy provide unit can energy the antenna individually.

The remainder of the setup is dealt with solely through the Lymow app for Android and iOS. As soon as a consumer account has been created, the robotic pairs with the smartphone through Bluetooth and connects to the Wi-Fi community. That is adopted by the firmware replace and pairing of the RTK antenna through QR code. The app guides you thru every step with tutorials.

The preliminary mapping is completed manually. Utilizing a digital joystick within the app, you hint the boundaries of the property and outline restricted areas similar to flower beds, bushes, or ponds. On our check web site, this course of took round 30 to 45 minutes.

A number of mowing zones could be created, separated, or merged, even retrospectively. If the RTK antenna is moved later, the complete map have to be recreated.

Lymow One Plus: Efficiency

Even within the first jiffy, it’s clear that the Lymow One Plus is in a unique league in comparison with different compact garden robots. The mower begins up rapidly and works in straight traces. The velocity could be repeatedly adjusted between 0.3 and 1.0 meters per second. At most velocity, the Lymow covers giant areas noticeably quicker than typical robotic mowers.

The minimize is spectacular after the primary mowing session. The excessive airflow straightens the blades of grass, the SK5 blades minimize cleanly, and the mulch is finely distributed. The benefit of the dual-blade design is clearly evident in dense or overgrown grass. Whereas many robotic mowers with small blades get slowed down, the Lymow continues to work reliably, even in taller grass. Fallen leaves are additionally shredded in turbo mode and distributed throughout the garden.

Noise ranges are one of many design’s weaknesses. In customary mode, the Lymow stays noticeably louder than typical robotic mowers. In turbo mode, the noise degree rises to 74 dB(A). This makes it nearly inconceivable to chill out within the yard whereas the mower is in operation.

Bumps and dips within the floor pose little downside for the Lymow. The floating mowing deck follows the terrain independently of the principle physique and retains the reducing peak fixed. Even on moist grass and gentle floor, the tracks discover grip the place wheels usually tend to spin. The Lymow tackled gradients of as much as round 30 levels on our check space with out slipping.

The impediment detection works reliably. Toys, patio furnishings, sprinklers, branches, and even a stuffed hedgehog positioned on the bottom are detected and averted proactively. The robotic reduces its velocity, swerves in a managed method, after which resumes its path. Solely very flat objects similar to a folding ruler mendacity on the bottom are detected late. Within the occasion of direct contact, the mower stops instantly.

The Lymow exhibits weaknesses when mowing edges. A strip of 10 to twenty centimeters stays alongside bushes, shrubs, or restricted areas. On driveable garden edging stones, nevertheless, the robotic achieves an nearly clear outcome as a result of it might probably roll over the stones utilizing a sequence. The protection distance could be decreased within the app, though this will increase the danger of the mower barely driving over the sting.

At temperatures under 68 levels Fahrenheit, the aspect discharge didn’t work reliably as a result of the rubber cowl turns into too stiff. In turbo mode, it labored flawlessly. In different modes, clippings sometimes collected. This didn’t have an effect on the mowing outcome. The clippings had been as an alternative distributed beneath the robotic. Due to the excessive floor clearance and the open mowing deck, the realm beneath the robotic is comparatively straightforward to scrub.

The Lymow app is complete and clearly structured. Path spacing, strip angle, cross-pattern, mowing sequence, variety of edge passes, and even the deactivation of the outer mowing motor could be configured per zone. An RTK diagnostic shows the variety of satellites and sign high quality in actual time. Maps can be backed up and restored if mandatory.

On a single battery cost, the Lymow achieved 142 minutes of mowing time at medium velocity on our 531 sq. meter check space, after which 42 % of the battery capability remained. Together with the 405-watt quick charger, three full mowing cycles are mentioned to be doable in twelve hours. Standby energy consumption is round 12.5 watts, although this rises to about 45 watts when the handbrake perform is activated on slopes.

Lymow One Plus: Conclusion

The Lymow One Plus is designed for big, steep lawns. That is exactly the place its uncommon design comes into its personal. The chain drive delivers monumental traction even on moist or uneven floor, the floating twin mower deck ensures a clear minimize even with tall or dense grass, and the RTK-VSLAM navigation works with astonishing reliability even in troublesome circumstances. Standard robotic mowers attain their limits a lot sooner in related environments.

The Lymow is much less appropriate for small, winding yards or these with exactly maintained edges. The excessive noise degree in turbo mode makes it much less appropriate for some residential environments. If you happen to’re primarily searching for a quiet, unobtrusive, handy resolution for the standard garden, you’re higher off with cheaper RTK fashions.

The value, beginning at round $3,199, appears excessive at first however is justified by the unusually strong know-how, the long-lasting LiFePO4 battery, the excessive protection fee, and the intense off-road functionality. Because of this, the Lymow is extra of a substitute for a small ride-on mower than a conventional robotic mower, which is exactly what makes it particular.
