Top 5 Best Robot Lawn Mowers

You have seen the list of the Best Robot Vacuum Cleaner, it is only time when you can get smart and clever robot lawn mowers that are just as reliable offering the best cutting result with minimal interaction. That time is now.

What To Look For in a Robotic Lawn Mower – Top 8 Considerations

1. Weather Proof – One the biggest factor when choosing a lawn mower if you have a big lawn is to make sure that it is weather resistant or weather proof. Being outside for long hours meant being under harsh weather conditions be it direct heat or rainy and cold climate. Both the electronics and motor needs to operate in the widest possible temperature range. Most lawn mowers have rain sensors. When it detects rain, it will stop mowing and return to base and will return again once the rain sensor clears up or according to a delay timer.

2. Automatic Charging – When the robot mower needs more power, it will find its way back to the charging station. Some mowers use guide wires to help the mower find its way back to the charging station to reduce searching time. This is particularly useful for complex gardens. Others require additional charging stations to be placed in each plot. The size of each plot is fixed to make sure that the robot mower does not run out of power before reaching the next charging station.

3. Maximum Lawn Area Coverage – Different robot mowers are design for different lawn sizes, these areas can be further divided into sections or plots, additional charging stations may be required for each plot depending on model. Some mowers lets you set the mowing pattern, irregular or straight and for any garden, square or odd shaped. Boundary or perimeter wires and pegs are used to confine the robot mower within an area or to mark the edge of the garden.

4. Security – Some robot mowers come equipped with anti-theft alarm that alerts you if the device is removed from your garden. This can be set according to your own choice. Others may incorporate a PIN code lock system for added protection.

5. Low Energy Consumption & Zero Emissions – most robotic mowers are energy efficient, run on rechargeable battery packs and cost only a fraction of the cost to charge compared to conventional lawnmowers. As it runs on electric only, there are no harmful emissions unlike fuel driven lawnmowers.

6. Safety – most lawn mowers come with lift and tilt sensors that cuts of the electricity to the motor and stops the blades from rotating when the unit is lifted off the ground or is tipped over. The blades are also a safe distance away from the edge of the machine giving it enough space to stop and redirect itself should it come across an obstacle and not cause any damage to the blades.

7. Programmable Timer and Settings – Using the settings panel, the robot mower can be personalised to fit many different gardens and to access the different features. You can decide if you want your mower to mow the lawn on different times and different days of the week.

8. Height Adjustment – just like your conventional lawn mower, you want to be able to adjust the cutting height to choose your preferred grass height.

Other considerations

  • Place for charging stations; preferably shaded, cold and dry or covered area that doubles as storage
  • Housing to charging station and robotic mower when not in use for protection from the elements
  • Power cable to charging stations with couplers and connectors
  • Take time to setup the boundary wires and peg for your garden, test and move this if required.
