Robot Mowers for Multiple Zones

"Multi-zone" appears on a great many specification sheets and means noticeably different things from one manufacturer to the next. It is worth pinning down what you are actually being offered.

The three things "multi-zone" can mean

1. Separate mapped areas. The mower holds several distinct maps and can be told to mow one of them. Whether it can get to them on its own is a separate question entirely.

2. Areas connected by a route. The mower knows a path from one area to another — down the side path, through the gate — and drives itself between them. This is the version most people assume they are buying, and it is the more capable one.

3. Scheduling by zone. Different areas can be mowed on different days or at different heights. Useful for a fine front lawn and a rougher back one.

Before buying on the strength of a multi-zone claim, work out which of these the manufacturer means.

The connecting route is the hard part

If your areas are joined by a path the mower can drive along, and the model supports transiting between zones, you have one mower doing the whole garden with no intervention. This is the ideal.

If the areas are genuinely separate — front and back with no accessible route, or separated by a road — no amount of multi-zone support helps. The mower physically cannot get there. You will be carrying it, or buying a second one.

Check honestly whether a route exists that a small machine can drive: wide enough, not too steep, no steps, and a surface it can grip.

Charging across zones

There is normally one base station. A mower working in a distant zone must be able to get back to it before the battery runs out — including the journey. On a large property that travel time eats into useful mowing time significantly.

Some systems allow a second charging point. If yours does not, factor the return journey into whether the mower can really cover the far zone.

When two mowers beat one

For a property with two substantial, genuinely separate lawns, two mid-range mowers often work out better than one large one:

• They cut simultaneously, so the whole garden is finished sooner.
• Neither wastes battery travelling.
• If one fails, half the garden is still being mown.
• The combined cost is frequently similar to one high-capacity machine.

The trade-offs are two base stations to site and power, two apps or two profiles to manage, and two sets of blades to replace.

Setting up zones well

• Map the largest, most visible lawn first and get it right before adding others.
• Give the connecting route a generous margin — this is where mowers get stuck.
• Set different cutting heights per zone if the grass types differ.
• Schedule the visible front lawn for the days you most want it looking good.

What to check before you buy

• Does the model support multiple zones, and how many?
• Can it travel between them by itself, or only store separate maps?
• Is there a real route between your areas — wide enough, gentle enough, no steps?
• Where does the base station go, and can the mower return from the furthest zone?
• Would two mowers actually be the simpler answer?
