The GreenWorks Optimow 4 is a fully automated robotic lawn mower designed to expertly maintain lawns of up to 450 square metres (that's just under two tennis courts). 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 cut 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.

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.

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. 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.

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.

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.

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.

The compact footprint of the Optimow makes it discreet when mowing, and its exceptionally low operating noise means you’ll forget its even there. Optimow 4 knows when its battery level is low, and automatically returns to the base station to charge itself, before resuming cutting when ready.

GreenWorks offers world-leading cordless products for use around the home and garden.-650.batteries include the best electronics and cell technology, and the products are designed for prolonged use in all kinds of garden environments .

Clean Technology

With this modern technology you really can replace your awkward electric tools, and your dirty, smelly, loud petrol products. Cordless tools start first time every time. There is no cable to get in the way, and cordless tools are much quieter than petrol versions, but best of all there are no emissions in use.

Keep your grass trimmed with the selection of lawn mowers, including robotic lawn mowers. Clean outdoor areas with a selection of pressure washers. Take care of your hedges and trees with the GreenWorks range of chainsaws and pruners, all powered by leading lithium-ion battery technology.

Product Families

Perfect for replacing electric products in small town and family gardens.
Two 24V batteries deliver combined 48V performance.
A more powerful choice for larger gardens and a true replacement for smaller petrol-powered tools.
A real powerhouse, this range can do everything that even large petrol products can do and is great for large plots of land and the toughest tasks.

Stop wearing out your arm on a pull cord. Stop filling fuel cans. The GreenWorks lithium system of tools requires none of that - plus its charging systems have received the Environmental Protection Agency's ENERGY STAR® approval rating.

ENERGY STAR-approved battery chargers, which are held to tight efficiency guidelines determined by the Environmental Protection Agency and Department of Energy, reduce energy usage by an average of 35 per cent from conventional garden tools.Petrol-powered lawn mowers launch as much pollution into the air in one hour as a vehicle does while driving 100 miles, the EPA reports. With more than 30 million lawn mowers in the USA alone, it takes a lot of pollution to trim the nation's properties.

All GreenWorks Tools products have a zero carbon footprint. No emissions, ever. The entire GreenWorks Tools product line will never release an ounce of carbon emission into the air. Plus, this efficiency requires no sacrifice from you. GreenWorks Tools will provide all the power you need without polluting the air or forcing you to keep hauling your petrol can to the nearest station (especially in the middle of mowing). No more tune-ups or maintenance. No more emissions.


GreenWorks Tools machines and battery chargers are protected against all defects under normal domestic use for a period of three years. Batteries are covered by a two year warranty for domestic use.
