Robot lawn mowers, if used correctly can be very beneficial for the lawn. Why?
Because the most important mowing rule is to mow little and often. In other words, remove a little bit of grass by mowing frequently which is exactly what a robot mower can do!
Here are some quick robo mower facts for consideration:
- They can cover lawn areas from a few square metres to over an acre (4000m2+)
- Most randomly cover the lawn within a wired perimeter yet others use GPS to cover the lawn more efficiently
- Not all have the power for slopes but some do
- Once set up to the shape and size of your lawn they are fully autonomous
- Some cut grass in the rain but it'll get caked in grass goo!
- Many robot mowers will work in multiple zones eg the back and front lawn
- Pivoting blades are more forgiving than fixed blades
- Height adjustment of the cutting deck is essential from at least 2cm to 6cm
- You still need to adhere to the seasonal cutting height recommendations here
- Recognised brands to consider
- Bosch
- Robomow
- Husqvarna
- Flymo
- John Deere
The downsides:
- Because they don't collect the clippings you can have a weed explosion so:
- ensure the lawn is robocut everyday so weed flowers are removed before they set seed
- if in doubt get the old mower out and keep the box on during weed seeding periods
- Installation on anything other than a simple lawn can be tedious so consider an installation service
- They're expensive but beneficial for you and the lawn if you're a reluctant gardener
- They can spread the dogs business a long long long way!
