The main benefit of robotic mowers is that they will mow your lawn more often than you would and keep the grass perfectly mowed all year round.
It is best to allow your robot to cover your ENTIRE lawn 2-3 times a week during the peak growing season in Australia. All Ambrogio models have an automatic schedule feature that lets the robot work this all out for you.
Otherwise, you can work out the number of hours per week needed to mow your lawn by a simple calculation:
Lawn size in m2 / m2 per hour your robot model mows = time required to mow the entire lawn
*For this example, the lawn size is 300m2 and the robot model is a Worx Landroid WR150E that mows 85m2 per hour.
300m2 / 85m2 = 3.5 hours to mow the entire lawn.
During peak growing season, multiply this number by 3:
3.5 hours x 3 = 10.5 hours mowing per week
It is then best to have your robot mowing either every day or every second day in peak growing periods. So, you can schedule the robot to mow for either 1.5 hours every day or 3 hours every second day.
* The above calculation is only a guide as different shaped lawns will take different durations to mow.
