Greenworks AI Mowbot C6A2 Wire-Free Robot Mower (Green, 600m²)

Does this mower need a boundary wire installed around the lawn?

No. This is one of its most significant practical advantages over older robot mower designs. It uses a combination of RTK satellite positioning and onboard Vision camera technology to navigate and define its working area digitally. You simply guide the mower around your garden once during setup and it maps the space automatically. There is no wire to bury, no trenching required and no risk of the wire being cut by a spade or fork later on.

How does the mower find its way back to the charging station?

The mower uses its RTK and Vision navigation system to locate the charging station precisely. When the battery runs low during a mowing session it automatically returns to the base to recharge and then continues where it left off. This means it can complete mowing sessions on larger lawns up to 600m² without any manual intervention from you.

What is the Time-of-Flight (ToF) sensor and why does it matter?

The ToF sensor works by emitting a signal and measuring how long it takes to bounce back from an object. This gives it accurate distance data regardless of lighting conditions. Standard camera-based sensors can struggle in shade, at dusk or on overcast days. The ToF sensor does not have this limitation. It detects obstacles within a defined area and steers around them reliably whether that is a garden chair, a child's toy or a pet that has wandered onto the lawn.

What is the maximum lawn size this mower can handle?

The mower is rated for lawns up to 600m². This is described as an average garden size. For context, 600m² is roughly the area of six standard tennis courts laid side by side. If your lawn is significantly larger than this you would need to consider a higher-capacity model. For most UK domestic gardens this capacity is more than sufficient.

Can I control the mower from my phone?

Yes. The mower is smart home compatible and connects to a dedicated app. Through the app you can set real-time or scheduled mowing sessions, define cutting zones, create restricted zones where the mower should not go and set up temporary or predefined areas. The app also includes a weather forecast feature so the mower can be programmed to avoid mowing in wet conditions when it may not be appropriate.

What cutting height options are available?

The cutting height is adjustable between 20mm and 90mm across 8 positions. This range covers everything from a short, neat lawn to a longer, more relaxed cut. The 20mm minimum is suitable for fine ornamental lawns while the 90mm maximum is practical for people who prefer a longer grass length or need to manage the lawn less frequently. The 200mm cutting width means it covers ground efficiently with each pass.

How steep a slope can this mower handle?

It is rated to climb slopes up to 24°. To put that in practical terms, a 24° slope is a fairly steep garden gradient steeper than most domestic lawns in the UK. The mower achieves this using its 24cm wheels which provide grip and stability on inclines. If your garden has a noticeable slope or tiered sections this mower is designed to manage them without losing performance or cutting quality.

What warranty comes with this mower?

Greenworks provides a 3-year product guarantee and a separate 2-year battery warranty. The battery warranty is worth noting specifically because robot mower batteries are a key component and replacing them can be costly. Having a dedicated 2-year warranty on the battery gives additional reassurance beyond the standard product cover. Greenworks describes itself as a world leader in electric tools and battery technology.
