Greenworks Optimow S Robot Lawnmower (Up To 300m², With Blades)

What size lawn is the Greenworks Optimow S suitable for?

The Optimow S is designed for lawns up to 300m². This puts it firmly in the small garden category. If your lawn is larger than this, you would need to look at a higher-capacity model. For a typical UK back garden, 300m² is a generous coverage area and will suit the majority of residential properties.

Does the Greenworks Optimow S require Wi-Fi to work?

No. The mower connects to your smartphone via Bluetooth only no home Wi-Fi connection is needed at any point. This is a practical advantage for gardens where the Wi-Fi signal from your router doesn't reach. You can set schedules and control the mower directly through the Greenworks app on your phone.

How steep a slope can the Optimow S handle?

The Optimow S is rated to handle slopes of up to 30%. To put that in context, a 30% slope means a rise of 30cm for every 100cm of horizontal distance that's a fairly steep garden incline. Most standard robot mowers are rated for significantly less, so this is a notable capability for people with uneven or sloped gardens.

How loud is the Greenworks Optimow S during operation?

It operates at 61dB. For reference, a normal face-to-face conversation sits at around 60 - 65dB. This means the mower is barely noticeable when running. Compare this to a petrol mower which typically produces 90 - 100dB and the difference in day-to-day noise impact is substantial particularly relevant if you have close neighbours.

How do you set up the Greenworks Optimow S?

Setup involves four main steps. First, lay the boundary wire around the perimeter of your lawn. Second, secure it with the pegs provided. Third, position the charging station. Fourth, connect the mower to the app on your mobile phone. The mower then charges automatically between mowing sessions and operates according to the schedule you set. No professional installation is required.

Is the Greenworks Optimow S waterproof?

Yes, the mower is fully waterproof. This means it can continue operating in light rain without damage. It also makes cleaning straightforward simply lift the lid and wash the unit down with a hosepipe. This is a practical feature for UK conditions where rain is frequent and garden equipment needs to cope with wet weather reliably.

What blades are included and how long do they last?

This bundle includes 9 replacement blades made from stainless steel. Each blade is double-edged, meaning when one cutting edge becomes blunt you can flip the blade and continue using the other side. This effectively doubles the working life of each blade. The stainless steel construction also resists rust and environmental degradation, which matters for a device that lives outdoors year-round.

What warranty does the Greenworks Optimow S come with?

The mower comes with a 3-year guarantee from Greenworks. Greenworks is described as a world leader in cordless tools and battery technology with a global reputation for customer service. A 3-year guarantee is longer than many competing robot mowers offer and provides solid reassurance on a product that represents a meaningful purchase.
