Which Landroid Vision Cloud should I buy: the 300, 500 or 1800?

Start with your lawn area and leave some headroom: the 300 suits small plots, the 500 lawns up to roughly 400 m², and the 1800 anything bigger. The three UK versions of the Worx Landroid Vision Cloud are rated for 300 m², 500 m² and 1,800 m². If you haven't measured, our lawn size tool will do it from a map.

The size gap between the 500 and the 1800 is large. Worx sells in-between sizes elsewhere in Europe, but they aren't on its UK store, so a lawn of 600 m² or so points you to the 1800.

Beyond area, the differences are:

• Cameras. The owner's manual indicates the 300 uses a single camera and the 500 a stereo pair, so the smallest model has less depth information to work with.
• Battery. 45 Wh, 72 Wh and 90 Wh respectively.
• Cut and height. The 300 and 500 cut 180 mm and use a dial on the mower; the 1800 cuts 220 mm and sets height from the app.
• In the box. The 1800 includes the Cut-to-Zero edge module and the RadioLink Wi-Fi extender. The edge module is an extra for the smaller two.

All three share the 30% slope limit, so if you have banks, look at the Worx Landroid Vision Cloud 4WD instead. Prices currently start from £599.99.
