Claims vs reality

Where the brand’s marketing and its own small print don’t agree.

  • They sayLawnMaster rates the OcuMow 18 for 800 m².

    In practiceThat's in auto-charging mode with the dock. Carried to another lawn as a drop-and-mow machine, the manual gives about 100 m² per battery charge. Source

  • They sayLawnMaster gives a 35% slope rating.

    In practiceThat applies inside the lawn. Where the lawn meets the boundary strip, LawnMaster's limit drops to 17% (10 degrees). Source

Which version do you need?

The standard OcuMow 18 is set up on the mower's dial and LCD. The App version adds Wi-Fi control through the OcuMow App; LawnMaster describes the app as optional. Otherwise they're the same mower.

How it navigates and sets up

The OcuMow 18 uses an HDR camera to recognise grass and find the edge of the lawn, with ultrasonic and bump sensors for obstacles. It has a charging dock, and uses GNSS satellite positioning only to find its way back to it. There's no perimeter wire, but LawnMaster's magnetic no-go strip (10 m supplied) marks areas it should avoid.

Camera-only boundary detection needs clear edges. A lawn bordered by paving, gravel or a raised edge suits it; one that fades into planting or rough grass doesn't. Our wired vs wire-free guide explains the options.

It's rated for 800 m² with the dock, slopes up to 35% inside the lawn, and passages of 100 cm. You can also carry it to a second lawn and drop and mow, which LawnMaster says covers about 100 m² per charge. For more on linking separate areas, see our complex gardens guide.

Cutting

The cut is 180 mm wide with three pivoting blades. Height has seven positions from 20 mm to 80 mm, a wide range for this price. There's no edge cutting. The guaranteed sound power is 68 dB(A), which is loud for a robot mower.

App, connectivity and security

The standard version is programmed on the mower. The App version adds Wi-Fi control through the OcuMow App. There's no cellular link or GPS theft tracking, but a PIN lock is fitted, and a rain sensor is fitted.

Running costs, warranty and support

The 86.4 Wh MX 24V battery is removable and shared with LawnMaster's other MX 24V tools. Cleva, which sells LawnMaster in the UK, gives a limited guarantee of 2 years. A shelter for the dock is sold separately. Prices start from £499.99.

OcuMow 18 questions and answers

Is the OcuMow 18 app version worth paying extra for?

Only if you want to control it from your phone; it doesn't mow any better. LawnMaster sells the LawnMaster OcuMow 18 in two versions, and apart from the app they're the same mower, with the same camera navigation, cut, battery and 800 m² rating. Their RRPs are £499.99–£549.99.

The standard model is set up on the mower's dial and LCD and runs to that schedule on its own. The App version adds Wi-Fi control through the OcuMow App, which LawnMaster describes as optional. That's handy for pausing it or changing the schedule from indoors, but it doesn't add app-drawn no-go zones: both versions use the supplied magnetic strip for areas to avoid. Neither has 4G, GPS theft tracking or a subscription.

Will the LawnMaster OcuMow 18 work if my lawn runs straight into flower beds?

Probably not well. The LawnMaster OcuMow 18 finds the edge of the lawn with an HDR camera that recognises grass, and LawnMaster says the lawn needs clearly defined borders for that to work. Paving, gravel or a raised edge give it a clear line; beds with plants spilling over the grass, rough meadow areas or ground cover don't.

There's no perimeter wire to fall back on. The mower uses satellite positioning only to find its way back to the dock, not to know where the lawn stops. For areas it should avoid inside the lawn, LawnMaster supplies 10 m of magnetic no-go strip that you lay on the ground, and more is sold separately. You could in theory run strip along a soft bed edge, but on a lawn with many soft edges that becomes a wire installation by another name.

Slopes near the boundary are a second point to check. LawnMaster rates it for 35% inside the lawn, but only 17% where the lawn meets the boundary strip.

If your lawn is mostly soft-edged, a wired mower such as the Einhell FREELEXO, or a wire-free mower that uses RTK mapping, will handle it more predictably. If you can add a mowing strip of bricks or edging along the beds, the OcuMow 18 becomes a much better fit. Our wired vs wire-free guide compares the approaches.

Frequently asked questions

How does the OcuMow 18 find the edge of the lawn?

An HDR camera recognises grass, and ultrasonic and bump sensors handle obstacles. It uses satellite positioning only to find its way back to the dock. The lawn needs clear edges, such as paving or gravel.

How do I keep it off an area of the lawn?

LawnMaster supplies 10 m of magnetic no-go strip that you lay down to mark areas it should avoid. There are no app-drawn zones.

Do I need the app version?

Not to mow. The standard model runs to a schedule set on its dial and LCD. The app version adds Wi-Fi control from your phone, which is handy but not essential.
