Which Robot Lawn Mower for My Garden? Sizing Guide

Area is the first filter, not the only one

Makers describe robot mowers mainly by maximum lawn area. That is a good starting point, but the number on the box is not enough. Garden shape, narrow passages, the number of separate lawns and whether the sky above is open all matter too. Below we sort the models in the robot lawn mowers catalogue into four area bands and explain when to choose a bigger model than your lawn size suggests. We checked prices in Polish shops on 10 October 2026.

Why you should leave a margin

The area on the spec sheet is an upper limit, reached under good conditions with long working hours. The makers' own data shows this clearly:

• The Dreame A2 2000, according to Dreame, mows 1,000 m² per day in standard mode and 2,000 m² only in efficient mode.
• The Husqvarna Automower 308V covers 800 m², but 500 m² in irregular mowing mode. The Automower 310E NERA covers 1,500 and 1,000 m² respectively.
• Per charge, the STIGA A 10v mows up to 210 m², the Mammotion YUKA mini 2 1000 about 250 m² and the Mammotion LUBA mini 2 AWD 1000 about 430 m². A larger lawn therefore takes several cycles with charging breaks in between.

If your lawn is exactly as large as the maker's rating, the mower has no reserve. Every pause for rain, the spring growth spurt or extra time spent driving between zones means it falls behind. With a complex layout or a slope, choose a model rated clearly above the size of your lawn.

Lawns up to 500 m²

For a small lawn a cheap wire-guided mower is enough. The Aspire R4 and SILENO minimo cost around PLN 2,000 (≈ EUR 460), but the wire has to be laid and pegged around the lawn. The Bosch VISIMOW18V-100 needs no wire or antennas, but it covers only 100 m² and the set has no docking station. The STIGA A 4 and Navimow i205 AWD work without a wire but need open sky.

Lawns from 500 to 1,000 m²

This band offers the widest choice. The Bosch Indego M+ 700 was a last unit at Morele.net, and the ECOVACS GOAT O800 RTK was awaiting delivery. For a lawn close to 1,000 m², go for a model rated at 1,000 m² or one from the next table. The YUKA mini 2 navigates by LiDAR and does not depend on a satellite signal, so it copes under trees.

Lawns from 1,000 to 2,000 m²

Price differences in this group are large. The Navimow i215 LiDAR mows up to 160 minutes per charge, the Automower 310E NERA about 50 minutes. The GARDENA smart SILENO free has no shopping cart on the maker's site; it is sold through partner shops. We read the Navimow X420 price at Robopunkt on 9 October 2026.

Lawns above 2,000 m²

Despite its name, the STIGA A 1500 is rated by STIGA for 2,500 m². It cuts an 18 cm swath, though, while the LUBA 3 AWD and Dreame A3 AWD Pro cut 40 cm and the GOAT A3000 33 cm. A narrower swath means longer working time on the same area. The GOAT A3000 promotion runs until 31 October 2026; the regular price is PLN 9,499 (≈ EUR 2,180). Segway also sells an X450 version for 5,000 m², but we have no Polish price for it in the catalogue. The professional Husqvarna CEORA 546 EPOS is meant for sports pitches and parks, not for a home garden.

Wire, RTK or LiDAR: what the navigation column means

Boundary-wire mowers are the cheapest in the catalogue (PLN 1,999 (≈ EUR 460) to 3,899), but they need installing. The SILENO minimo kit contains 150 m of wire and 150 pegs, the SILENO life 200 m of wire and 300 pegs, and the Indego M+ 700 comes with 175 m of wire and 240 pegs. On a large or irregular lawn that means a fair amount of work or a paid installation.

RTK-GNSS mowers need no wire, but some need a reference antenna. The STIGA A 4 and A 1500 include one, while according to STIGA the A 10v does not need one. Network RTK (Navimow i205 AWD, LUBA mini 2 AWD) requires mobile network coverage. Watch the connectivity cost too: on the STIGA A 4 it is included for 2+1 years, after which a data package has to be bought, while the LUBA mini 2 AWD comes with a 4G module with three years of data.

LiDAR mowers such as the YUKA mini 2, Navimow i215 LiDAR or GOAT O1200 do not depend on a satellite signal.

Garden shape: narrow passages and several zones

Two gardens of the same size can need different mowers. The most common obstacles are:

• Narrow passages. The mower has to get between parts of the lawn, for example past the house. The YUKA mini 2 1000 fits through 55 cm, GARDENA SILENO models with CorridorCut through 60 cm, the GOAT O800 through 0.7 m, the GOAT O1200 through 0.8 m, and the GOAT A3000 needs 90 cm. Measure the narrowest point before buying.
• Several separate lawns. Wire-free mowers handle zones in the app: the STIGA A 4 up to 2, the STIGA A 1500 up to 10, the STIGA A 10v up to 15, and the Navimow H210 and LUBA 3 AWD up to 30. If there is no drivable route between zones, you will have to carry the mower.
• Trees and buildings. RTK needs open sky, and the Husqvarna 308V and 310E NERA in wire-free mode also need Wi-Fi coverage across the whole lawn. In a shady garden, LiDAR models tend to do better. We cover the differences in “Wire-Free Robot Mowers”.
• Slopes. Steep ground rules out some models, and wire-guided mowers have a separate, lower figure for the edge. Details in “Robot Lawn Mower for Slopes”.

Summary

Measure your lawn, then choose a model with spare area, and more spare the more complex the garden is. For a small, flat lawn a wire-guided mower at around PLN 2,000 (≈ EUR 460) is enough. Gardens from 1,000 m² upwards mostly mean wire-free mowers at PLN 4,299-11,606 (≈ EUR 985–2,660). General buying criteria are covered in “How to Choose a Robot Lawn Mower (2026)” and the full cost of buying and running a mower in “Robot Lawn Mower Prices in Poland (2026)”.
