This Robot Lawn Mower is Wild | Lymow One Plus Overview

A tracked design for difficult yards

The Lymow One Plus keeps the distinctive design introduced with the original Lymow One. Instead of using small caster wheels, it has a rugged aluminium frame, caterpillar-style tracks and two rotary blades mounted at the front. The design is intended to address conditions that can cause other robotic mowers to lose traction, including muddy ground and sloping lawns.

According to the overview, both Lymow models can climb slopes up to 45 degrees, described as a 100% grade. The video also highlights the use of two 16-inch solid rotary blades, which are more similar in concept to blades found on a conventional petrol mower than the small pivoting blades used by many robotic mowers. The stated aim is to handle thicker grass, including St. Augustine.

More cutting power and revised airflow

The original Lymow One has a peak motor output of 1,200 watts. The One Plus increases this to a claimed 1,785 watts, representing a 50% increase in peak cutting power.

The newer model also introduces the Lymow Cut System 2.0. Its front cutting decks have been redesigned to create what Lymow calls cyclone airflow. This airflow is intended to pull grass upright before it reaches the SK5 steel blades. The overview says this should help produce a more even cut when grass is flattened or slightly damp.

The airflow is also designed to help move clippings away from the cutting deck and reduce clogging in wet conditions. These points are presented as design intentions and observations from the hands-on overview, rather than results from a completed long-term review.

Navigation and camera changes

Both models use RTK and visual navigation, combining satellite positioning with stereo-vision cameras. This allows them to map a yard and operate without a boundary wire.

The One Plus uses Lymow Multifusion Navigation 2.0. Lymow says it trained its AI models for at least a year using thousands of real-world backyard scenarios. The stated goal is improved recognition of objects such as garden hoses, pets and small animals.

A hardware change is the heated camera housing. This is intended to keep the lenses clearer in conditions involving morning dew or fog. The overview notes that this may be particularly useful in foggier or dewier locations, although this benefit was not something experienced in the presenter’s suburban Perth testing.

Maintenance and battery options

On the original Lymow One, the charging contacts are positioned on the side. The overview explains that mud, moisture and other debris can build up there, sometimes requiring the heavy mower to be turned over for cleaning. The One Plus moves the contacts to the front upper section, keeping them farther from debris underneath the machine.

The tracks also receive a self-cleaning system with a rubber barrier and specialised brushes intended to remove grass and debris. This is designed to reduce buildup that can contribute to traction or track-tension issues on the original model.

The One Plus is available with either a 5Ah battery, claimed to cover up to 4,452 square metres per day, or a 10Ah battery, claimed to cover up to 7,000 square metres per day. It also includes a 10-amp fast charger to reduce charging time.
