The short version

Key points

  • The One Plus increases peak cutting power from 1,200 W to 1,785 W and uses dual SK5 tool-steel rotary blades.
  • Its tracked drive is rated for slopes up to 45 degrees, although zero turns can dig holes in weak or dry lawns.
  • Ground clearance has increased from about 5 cm to approximately 7 cm, while internal brushes and scrapers help clean the tracks.
  • RTK-SLAM navigation operates without boundary wire and combines satellite data with visual recognition.
  • The mower handled a deliberately overgrown 30 cm patch, although very tall grass may need a second pass for a neat finish.

A tracked design for difficult lawns

The Lymow One Plus retains the industrial, tank-like design of the earlier Lymow One, using continuous tracks instead of conventional plastic wheels. The track system distributes the mower’s weight across a longer contact area and is rated for slopes up to 45 degrees, described in the review as a 100% grade. It also provides strong grip in muddy conditions.

The design has limitations. Zero-turn manoeuvres can still dig holes, particularly when the lawn is weak or dry. The One Plus has approximately 7 cm of ground clearance, compared with about 5 cm on the original model, allowing it to cross exposed roots, fallen branches and uneven lawn transitions more easily.

More powerful cutting system

The One Plus introduces the manufacturer’s Cut 2.0 system, increasing peak cutting power from 1,200 W to 1,785 W. Rather than using small pivoting razor blades, it has two rotary blades made from high-rigidity SK5 tool steel and a 400 mm cutting width.

The deck uses cyclone airflow to pull grass upright before it reaches the blades. This is intended to reduce uncut blades that would otherwise be lying flat. The airflow also pushes clippings out more forcefully, helping reduce wet-grass buildup beneath the deck. The review warns that the suction is strong enough to pull up roots or dry grass if the cutting height is set too low.

Testing overgrown grass

During testing, the mower was sent into a 30 cm patch of grass that had been left to grow for several months. It handled the challenge, although extremely tall grass may require a second pass to achieve a clean finish. The review describes performance as particularly strong on grass below roughly 15 to 20 cm.

This makes the One Plus more suited to difficult or infrequently maintained areas than many robot mowers designed for short, regularly cut suburban lawns.

Wire-free navigation and obstacle recognition

The One Plus uses RTK-SLAM navigation, combining satellite data and visual cameras to map the property without a boundary wire. Its mapping capacity is stated as 15 acres, with support for up to 80 zones.

A heated camera housing is designed to reduce condensation from morning dew, allowing the mower to begin work earlier when the lens might otherwise fog. The updated obstacle-recognition system can identify pets, hoses and small wildlife, including marsupials, then plan a smoother route around them instead of simply bumping into them and turning away. Some uncut grass remains around obstacles, which is a safety trade-off given the mower’s powerful blades.

Battery, app and maintenance changes

The mower has a stated 15,000 mAh LiFePO4 battery and includes a 10-amp fast charger that was previously optional. Charging from 10% to 90% is said to take about 90 minutes, while daily coverage is listed as 1.73 acres per day.

The app supports mowing schedules, cutting-height adjustments from 30 mm to 60 mm, and mower-status monitoring through 4G, Wi-Fi or Bluetooth. Safety equipment includes an emergency stop, lift sensors and blade stopping in under one second when the mower is tilted or interrupted.

A significant maintenance change is the relocation of the charging contacts from underneath the mower to the top of the deck. This keeps them away from damp grass, mud and clippings, and the contacts have a brush that cleans them during docking. The aluminium-alloy mower is rated IPX6 for weather resistance and weighs approximately 35.6 kg.

TechManPat’s conclusion

I think the Lymow One Plus addresses nearly all of the practical concerns from the first model, particularly through its stronger cutting system, self-cleaning tracks and relocated charging contacts. I see it as a replacement for a petrol-powered ride-on mower or professional mowing service, rather than a sensible choice for a flat 500-square-metre lawn. For a property of about 1.5 acres with steep hills, thick grass and obstacles, I think it is the type of robot mower that can tackle a genuinely difficult yard. The transcript states a price of $55,000, so I consider it a substantial investment aimed at specialised use.
