Compact robotic lawn mower for small lawns up to 450m2

The Greenworks Optimow 4 is a fully automated robotic lawn mower designed to expertly maintain lawns of up to 450m2. Installation is simple with everything you need included, simply peg down a perimeter wire and connect to the base station.

Once installed the Optimow will mow the lawn according to your pre-set schedule, charging itself when necessary. You have full control from the Bluetooth enabled App to alter mowing times if required, and the built-in lift and collision sensors ensure safety at all times.

Compact & Lightweight

The compact and lightweight design of the Greenworks Optimow 4 makes it suitable for smaller lawns of up to 450m2 (just under 2 tennis courts). The compact footprint of the Optimow makes it discreet when mowing, and its exceptionally low operating noise means you’ll forget its even there.

Full Control from the Greenworks App

The Optimow 4 can be controlled via Bluetooth from the Greenworks app, where you can monitor and update the machine as well as alter settings and schedules. Connectivity works up to 32 metres from the machine.

Safety First

The Optimow 4 is designed with safety in mind, featuring an integrated lifting sensor which automatically stops the blades when the machine is lifted. The collision sensors allow Optimow to recognise obstacles, with the machine stopping and turning away to mow elsewhere.

How does it work?

The concept is simple and involves a boundary wire around the perimeter of your lawn, this can be pegged into the lawn or buried, once installed the Optimow 4 mows the lawn in a random pattern leaving a carpet like finish. For complex garden shapes, the optional guide wire allows the Optimow to easily navigate back to the base station for charging.

How does it know where it has already cut?

The Optimow 4 doesn’t know where it has mowed and doesn’t need to. By mowing a random pattern regularly, it covers the whole lawn easily only ever cutting very small amounts at a time, leaving a perfectly level surface.

How does it charge?

Optimow 4 knows when its battery level is low, and automatically returns to the base station to charge itself, before resuming cutting when ready.

Where do the grass clippings go?

The cutting method is ‘little and often’ which leaves very small grass clippings which fall down to the grass roots and are not visible to the eye. This grass then naturally decomposes and acts as a fertiliser, giving a healthier and greener looking lawn.

How often does it need to mow?

Depending on the size of your lawn you set a mowing schedule either on the machine or via the Greenworks app, Optimow 4 will then follow this schedule automatically.
