LawnMaster OcuMow 18 Robot Mower (Orange, No Boundary Wire)

Do I really need no boundary wire at all?

Correct no boundary wire is required. The mower uses a combination of GPS positioning and an onboard camera with Optical Grass Recognition (OGR) software to navigate. It relies on hard physical borders such as fences, walls, patio edges or garden edging to contain it. If you have soft borders like open flower beds, you can use the included 10 metres of magnetic No-Go strip to block those areas off. Multiple reviewers confirmed the mower was running within 20 minutes of unboxing.

What happens when the battery runs low?

When the battery level drops, the mower uses its GPS and camera to locate the charging station and returns to it automatically. The charging station needs to be plugged into an outdoor power socket. Once recharged, it resumes its mowing schedule. In Drop & Mow mode on a secondary lawn, it cannot return to the station itself it simply stops and waits on the lawn to be collected and carried back manually.

Can I use it on more than one lawn?

Yes. The Drop & Mow feature is designed exactly for this. Carry the fully charged mower to any lawn a front garden, a separate rear garden or even a neighbour's lawn and select either spiral or random cutting pattern. No additional setup or boundary configuration is needed. When the battery runs low it will stop and wait. One reviewer with five separate grassed areas uses it this way regularly and purchased a second battery to speed up the process.

Does it need an app or WiFi to work?

No. There is no app and no WiFi required. The mower is controlled entirely via an onboard dial and LCD display. You set the schedule and cutting height directly on the machine. This means it continues to function regardless of internet connectivity or whether the manufacturer's servers remain active. Several buyers specifically highlighted this as a reason they chose this model over competitors.

What lawn size is it suitable for?

The mower is rated for lawns up to 800m². That covers small terraced gardens right through to larger suburban plots. The 18cm cutting width and random or spiral cutting patterns mean it covers ground methodically over multiple sessions. For best results the manufacturer recommends running it frequently rather than in single long sessions this keeps the grass short enough for the mulching system to work effectively.

What cutting heights are available and which should I use?

There are 7 cutting height positions ranging from 20mm to 80mm. For longer or overgrown grass the manufacturer recommends starting at 60mm and gradually reducing the height over successive mowing sessions. Dropping straight to a low cut on long grass can stress the lawn. The mulching blade returns fine clippings to the soil as nutrients so there is no grass collection required.

Is it safe around children and wildlife?

The mower has lift, tilt and bump sensors that stop the blades immediately if it is picked up or collides with an object. PIN code protection prevents unauthorised use. Crucially it only operates during daylight hours this is a deliberate design choice to protect nocturnal wildlife such as hedgehogs which are active at night. It does not operate in the dark so animals that come out after dusk are not at risk.

What guarantee and support comes with it?

The mower comes with a 2-year domestic guarantee covering the robot mower, charging station and battery. LawnMaster is a brand by Cleva and has a UK-based customer support team. Spare parts are available for up to 5 years after purchase. It is worth noting that one reviewer reported a GPS failure within a year and found customer service response times slow so it is worth keeping your proof of purchase and registering the product promptly.
