How we chose these robot lawn mowers
UK gardens are rarely a flat rectangle, so slope handling and mowing area were the first filters: every mower here is rated by its own manufacturer for a specific m² capacity and a maximum incline, and we've quoted both rather than a single headline number, because most brands quote a lower area for irregular-shaped lawns than for a simple square. Second, we split mowers by navigation type — boundary wire, GPS/satellite-corrected wire-free (EPOS, RTK), or camera-based vision — because that decides both the upfront installation effort and the ongoing reliability in a garden with trees or fences that block satellite signal. Third, and specific to this site, we checked whether each mower actually exposes anything to Home Assistant: an official cloud integration, an actively maintained community one via HACS, or nothing at all. Prices are UK manufacturer list prices or a single retailer figure seen in September 2026 and move often with seasonal discounting, so treat them as bands rather than exact quotes.
We didn't include Segway's new Navimow H5 Pro, which debuted at IFA Berlin 2026 with a hedgehog-detecting camera system — Segway hasn't confirmed a UK price, release date or Home Assistant support yet, so it's one to watch rather than buy today.
The best robot lawn mowers for UK gardens in 2026
1. Husqvarna Automower 435X AWD NERA — best overall
Who it's for: anyone with a garden up to roughly 5,000m² (or 3,500m² if the shape is irregular) who wants to skip laying a boundary wire and doesn't mind paying for it. Husqvarna's own UK product page lists the 435X AWD NERA at £5,299 RRP, and specifies slope handling of up to 70% inside the mowing area and 50% at the boundary itself, backed by all-wheel drive and an articulated chassis.
Navigation is Husqvarna's EPOS™ satellite-based system, which draws virtual boundaries instead of a physical wire — though a wire remains an option if GPS reception is patchy under trees. The catch is the price and, in areas with weak cellular coverage, the possible need for an EPOS RS1 reference station to keep the positioning accurate. On the Home Assistant side, this is the strongest pick here: the official husqvarna_automower integration landed in Home Assistant 2024.3, uses a cloud push connection via websocket (so no polling), and supports start/park commands and schedule overrides from the Automower Connect app account — though it doesn't support the separate Bluetooth-only automowers.
2. Worx Landroid M500 Plus (WR165E) — best budget pick
Who it's for: smaller, simpler lawns where laying 150m of boundary wire for an afternoon is an acceptable trade for a much lower price. Worx's own UK store lists the M500 Plus at £599.99 RRP (routinely discounted well below that), covering up to 500m² with AIA intelligent navigation and a maximum 35% slope — a fraction of the Automower's incline tolerance, so it's a poor fit for a steep back garden.
Because it needs a boundary wire, installation is more physical work than the wire-free picks, but that wire also means far more predictable coverage in a garden with thick tree cover that would confuse GPS. For Home Assistant, there's no official integration, but the community-maintained Landroid Cloud add-on (installed via HACS, built on the pyworxcloud library) exposes mower state, battery and start/stop control by talking to the same Worx cloud account as the official app.
3. Worx Landroid Vision Cloud 2WD 500m² (WR305E) — best wire-free budget pick
Who it's for: anyone who wants wire-free convenience without paying Husqvarna or Mammotion prices. Worx's own UK listing prices the Vision Cloud 500m² at £799.99 RRP (frequently discounted, seen at £699.99), and it needs no boundary wire at all — it combines RTK cloud-corrected satellite positioning with a stereo camera running Vision AI and V-SLAM, so the mower can keep navigating accurately in shaded or tree-covered spots where satellite signal alone would drop out.
The catch is coverage: 500m² is the smallest model in the Vision Cloud range, so a larger wire-free lawn means stepping up to the 1,000m², 1,800m² or 4,000m² 4WD versions at correspondingly higher prices. Home Assistant support again comes via the community route — the same pyworxcloud-based ecosystem covers Vision Cloud models, and a dedicated ha-landroid-vision HACS integration adds RTK map rendering and live position tracking specifically for this range.
4. Mammotion Luba 2 AWD 5000X — best for very steep slopes
Who it's for: gardens too steep for most wire-based mowers. Mammotion's own UK store lists the Luba 2 AWD 5000X at £2,399, covering up to 5,000m² with a claimed maximum slope of 80% (38.6°) — well beyond the Automower's 70% and the Worx models' 35%. It needs no perimeter wire at all: navigation combines Mammotion's UltraSense AI Vision cameras with RTK positioning, and the company's iNavi service adds NetRTK correction without requiring you to install a separate physical base station.
The trade-off is charging cadence rather than slope: Mammotion quotes a maximum of around 1,200m² of cutting per charge on the dual 400mm cutting-disc system, so a full 5,000m² garden needs several charge cycles across the day. Home Assistant support is entirely community-built — the actively developed Mammotion-HA integration (built on the PyMammotion library, which talks to the mower over MQTT, cloud and Bluetooth) exposes mowing status and control, though as with any young community project expect the odd rough edge as new firmware ships.
5. Gardena SILENO life 750 — best if you're already in the Gardena smart system
Who it's for: households that already own Gardena smart system kit, such as the Water Control Bluetooth watering computer we recommend for irrigation, and want their mower on the same app. UK retailer pricing for the SILENO life 750 (covering up to 750m²) runs around £1,200, with a claimed maximum slope of 35% — the same ceiling as the cheaper Worx boundary-wire models, so it isn't a steep-garden pick.
The SILENO life connects either directly over Bluetooth from up to 10m away, or through Gardena's smart Gateway for full app control and its LONA intelligence garden-mapping feature. The important caveat: Gardena's own smart system product pages make no mention of Home Assistant, a public API, or any third-party integration route — this is a mower that stays inside the Gardena app ecosystem, so only pick it if you're happy controlling it separately from Home Assistant, or already are for irrigation.
Boundary wire or wire-free RTK: which robot lawn mower suits your garden?
Boundary-wire mowers (the Worx Landroid M500 Plus and Gardena SILENO life here) follow a low-voltage cable you peg or bury around the lawn edge, so they cost less and behave predictably under heavy tree cover, but installation takes an afternoon and moving a flower bed means moving the wire. Wire-free mowers (the Husqvarna Automower 435X AWD, Worx Vision Cloud and Mammotion Luba 2) draw a virtual boundary in an app and navigate with RTK or EPOS satellite positioning, often helped by cameras, so setup is quicker and the map is easy to edit.
The trade-off is signal: satellite positioning can drift under dense trees or beside tall buildings, which is why camera-assisted systems and optional reference stations exist, and why wire-free models cost noticeably more at the top end. As a rule, choose wire for a small, tree-heavy, simple lawn on a tight budget, and wire-free for large, sloped or irregular gardens with reasonable sky view. The newest wire-free design is Segway's Navimow H5 Pro, shown at IFA 2026 but with no UK price yet.
Do robot lawn mowers actually work with Home Assistant?
Yes, but the depth of integration varies a lot by brand. Husqvarna is the only manufacturer here with an official Home Assistant integration, added in the 2024.3 release and built on Husqvarna's own cloud API — it's the safest long-term bet if Home Assistant control matters more to you than price. Worx and Mammotion both rely on actively maintained community integrations installed through HACS, which work well day to day but can lag behind official app updates when the manufacturer changes its cloud API. Gardena's SILENO range, by contrast, has no confirmed Home Assistant or public API route at all as of this review — it's app-only, so factor that in if a unified dashboard matters to you.
Which robot lawn mower should you avoid if you don't want to lay a boundary wire?
Skip the Worx Landroid M500 Plus and the Gardena SILENO life if a physical boundary wire is a dealbreaker — both need one laid around the lawn's edge before they'll work. If you want wire-free convenience without the Husqvarna or Mammotion price tag, the Worx Landroid Vision Cloud 500m² is the cheapest genuinely wire-free option here, provided your garden fits inside its 500m² limit; larger wire-free lawns push you back up to the Automower or a bigger Vision Cloud/4WD model.
