The Old Way: Wires and Random Bouncing

First-generation robotic mowers required a boundary wire buried around your entire lawn — an expensive, fragile installation — and then mowed in random patterns, bouncing off the wire like a screensaver. Coverage was uneven, mowing took forever, and every landscaping change meant re-burying wire.

The New Way: RTK Satellite Precision

RTK (Real-Time Kinematic) positioning takes standard GPS — accurate to a few metres — and corrects it using a fixed reference station, achieving 2-3 centimetre accuracy. The mower knows exactly where it is at all times, with no wires at all.

What Centimetre Accuracy Enables

  • Perfect parallel stripes — systematic passes instead of random coverage, cutting mowing time by half or more
  • Virtual boundaries — draw your lawn, flower beds and no-go zones in the app; change them anytime in seconds
  • Multi-zone lawns — front and back lawns handled with defined transfer paths
  • Precise edging — the mower tracks boundaries exactly, minimising manual trimming

AI Vision: The Second Sense

Premium mowers pair RTK with AI vision to recognise obstacles — garden furniture, hoses, pets, children's toys — and steer around them smoothly. Rain sensors pause mowing in wet conditions; anti-theft GPS tracks the mower if it ever leaves your property.

Is Your Lawn Suitable?

RTK mowers suit lawns from a few hundred square metres to several acres — ideal for independent homes, farmhouses and villas in Bangalore, Lucknow and Delhi NCR, as well as resorts and school campuses. Slopes up to ~24° and complex shapes are handled comfortably.
