Robot mowers have evolved rapidly. For UK households with small gardens (up to about 400 m²), modern models offer plug‑and‑play setup and advanced navigation that eliminate boundary wires. Brands such as STIGA, Mammotion, Segway Navimow, Kress and EGO now provide compact, wire‑free mowers with smartphone‑controlled mapping and systematic cutting patterns.
This article explores the best robot mowers for small gardens in 2026, focusing on ease of installation, reliability and cutting quality.What qualifies as a “small garden”?
Lawn area: Typically under 400 m² – the average terraced garden in the
UK is around 200 m².
Complexity: Small plots often have narrow passages, patios and flowerbeds requiring precise navigation.Noise & convenience: With close neighbours, quiet operation and hands‑off maintenance are priorities.
Top wire‑free models for small gardensSTIGA A4 – Instant digital mapping for up to 400 m²STI
GA’s new A4 robot mower, launched in 2025, is designed for lawns up to 440 m².
Its standout feature is the Active Guidance System (AGS), which maps your garden, anticipates GPS signal variations and plans efficient mowing paths. Homeowners define mowing areas through the STIGA.GO App, eliminating the need for physical perimeter wires.
Installation is therefore as simple as placing the mower on the lawn and creating a digital boundary via the app. The A4 provides 90 minutes of scheduled daily mowing and runs quietly, with advanced obstacle detection and retractable blades for safety. STIGA’s systematic cutting ensures complete coverage and healthier grass.
Yuka mini 2 is an upgraded compact mower for small‑to‑mid lawns.
On the Yuka mini 2, Mammotion introduces Tri‑camera AI Vision + NetRTK so the mower can map multiple zones and start mowing instantly via the DropMow mode. With all‑wheel drive and an Ultra‑Close Edge Cutting side disc, it trims right up to walls and flowerbeds. Installation is a true plug‑and‑play experience—open the app, map your garden and press go.
The Yuka mini 2 suits lawns up to roughly 10,760 sq ft (~1,000 m²) and handles steep slopes thanks to Mammotion’s proven 4WD platform.
Series offers wire‑free installation and is aimed at smaller gardens. These models use network RTK, visual SLAM and optional solid‑state LiDAR to map and navigate lawns with centimetre‑level accuracy.
Segway markets the i2 mowers as “drop and mow” devices—no perimeter wires or physical antennas are needed. The i206 AWD covers 0.15 acre (~600 m²) and the i210 AWD covers 0.
37 acre (~1,500 m²), both featuring AWD traction for slopes and an app that guides setup, scheduling and zone creation. These mowers integrate Segway’s Xero‑turn AWD system to reduce turf damage when turning.
Kress RTKⁿ
Kress’s RTKⁿ series is one of the most user‑friendly wire‑free solutions.
The KR161 model is designed for ¼‑acre lawns (about 1,000 m²). Kress emphasises that its mowers require no boundary wire, no beacons and no antenna on your property—the RTKⁿ system delivers inch‑level accuracy via a network of base stations. Simply place the mower, define your zones in the app and let it mow systematic stripes across your lawn.
Kress’s satellite‑guided mowers follow parallel lines to create fresh‑cut stripes and encourage healthy grass growth. For very small gardens, the KR161 offers a professional‑level finish without complex installation.
EGO RMR1500E (AURA‑R2) – Intelligent mapping and app control
EGO’s AURA‑R2 platform, introduced for 2026, includes the RMR1500E model rated for lawns up to 1,500 m².
The mower maps up to 40 distinct zones, travels between them across paths or driveways and adjusts schedules and cut heights via the EGO Connect app. Installation is flexible: mount the PATH IQ antenna on a pole or wall or use network RTK if available. Users receive three years of data connectivity and can control the mower using Bluetooth, Wi‑Fi or 4G.
Are wired mowers still relevant?Traditional wired mowers like the Worx Landroid M500 Plus and Gardena Sileno City remain budget options; however, they rely on boundary wires prone to damage and require professional installation or significant DIY effort. With wire‑free technology now mainstream, we recommend prioritising plug‑and‑play models unless you have a very limited budget.
Choosing a small‑garden mowerWhen comparing models, consider:
Kress and EGO require no trenching. The app‑based setup typically takes less than an hour.
Kress) offer ±1 cm precision, while RTK + vision systems (Segway, EGO) provide reliable guidance even under trees.
Slope capability – If your garden has inclines, check the slope rating. STIGA A4 handles moderate slopes; Mammotion’s Yuka mini 2 uses 4WD for steeper areas; Navimow’s AWD models also excel on hills.Battery runtime – For lawns under 400 m², most models finish in a single session.
Look for multi‑zone management, adjustable cutting height (e.g.,
