Weimilor RTK+TOF+Vision Robot Lawn Mower (Wire-Free, 3000㎡)

Does this mower really work without any perimeter wire?

Yes. The Weimilor uses RTK-GPS combined with Visual Inertial Odometry to map your lawn and establish virtual boundaries through the app. There is no wire to bury, no installation tools needed and no ongoing wire maintenance. Once you've mapped the lawn via the app, the mower navigates within those digital boundaries. This is a significant practical advantage over older wire-based systems which can take several hours to install and are vulnerable to damage from spades or forks.

How large a garden can it handle?

The mower covers up to 3000㎡ (0.75 acres). That's roughly the size of half a football pitch. For the majority of UK residential gardens which typically range from 50㎡ to 500㎡ this gives substantial headroom. The product listing also references a 6000㎡ configuration, so there may be extended coverage options available depending on the variant purchased.

What slopes can it manage?

It handles gradients up to 45%. To put that in context, a 45% slope is steeper than most garden banks and considerably steeper than the 25 - 30% limit found on many competing robot mowers. The powerful drive system is designed for off-road terrain, making it suitable for gardens with uneven ground, raised sections or sloped lawns that would defeat lighter-duty models.

How does the obstacle avoidance actually work?

The mower uses two complementary systems. The HD front camera provides visual detection of objects ahead, while Time-of-Flight (ToF) sensors measure the precise distance to obstacles in real time. When it detects a fixed obstacle like a wall or fence, it stops. For moveable objects people, pets, garden furniture, rocks or tree roots it steers around them. It also monitors grass density and slows down when cutting is heavier, which protects the motor and improves cut quality.

Is it noisy enough to disturb neighbours?

Operating noise is below 67dB. For reference, normal conversation sits at around 60 - 65dB and a typical petrol mower produces around 90 - 95dB. At sub-67dB the Weimilor is quiet enough to run during the day without causing significant disturbance. It's worth checking your local council guidelines on garden machinery hours, but the noise level is well within what most residential areas would consider acceptable.

How do I set cutting height and can I have different heights in different zones?

Cutting height is adjustable across 27 positions ranging from 2cm (0.8 inches) to 8.9cm (3.5 inches). The app allows you to assign different cutting heights to different zones within your garden. So if you want a tighter cut on a formal lawn area and a longer cut on a wilder section, you can configure that directly from your phone without any manual adjustment on the machine itself.

What happens when the battery runs low?

When the battery level drops, the mower automatically navigates back to its charging station and docks itself. The charging station is included in the box. Once charged, it can resume mowing according to its schedule. This automatic return-to-charge behaviour means you don't need to monitor battery levels manually the mower manages its own power independently.

How does the anti-theft system work in practice?

If the mower is lifted off the ground or moved in a way that doesn't match its expected behaviour, an alarm sounds immediately and the unit locks itself. To unlock it, the correct PIN code must be entered. Without the PIN the mower cannot be operated. This is a meaningful security feature for gardens that aren't fully enclosed or where the mower might be left running unattended. It also protects against unauthorised use by children.
