Stiga’s mid-tier wireless robotic
The A 5500 sits in the middle of Stiga’s Autonomous robotic mower range — 5,500 m² (≈1.36 acre) coverage envelope, GPS-RTK satellite guidance, 40% slope handling, no perimeter wire required. The argument is the same wireless-RTK generational shift that anchors the flagship A 7500, sized for the property profile that doesn’t need the full 1.85-acre envelope and shouldn’t pay for it.
Spec snapshot

| Power | Lithium-ion, fully autonomous battery management |
| Best fit | Mid-size estates (0.7-1.4 acres), high-end residential, school formal lawn |
Where the A 5500 actually earns its keep
Two typical buyer profiles. First: mid-size country estates and large gardens with 0.7-1.4 acres of amenity lawn where the buyer has hit the same operator-cost-displacement maths that justifies the A 7500 at larger sites — but the property doesn’t need 1.85-acre coverage and shouldn’t pay £2k extra for unused capacity. Second: high-end residential properties where night-time silent mowing genuinely matters (urban-fringe properties with neighbour considerations, mews-pattern lots where weekend cutting noise is a real factor) and the cut quality of robotic frequency-cutting matches the buyer’s amenity-lawn expectations.
The quieter argument that the spec sheet doesn’t surface: cut quality from frequency-cutting. The A 5500 mows the same lawn 4-5 times per week instead of weekly rotary cutting once. Cut height stays within 2-3 mm of target across the working week, and the lawn receives the same fine-trimming treatment that championship-grade greens-keeping uses to maintain surface density. For amenity buyers who care about lawn condition, the cut quality is a hidden upgrade most don’t expect at the price tier.
Versus the A 7500 and A 3000
The Stiga Autonomous ladder, by coverage envelope:
- A 3000 (£2,795): 3,000 m² (≈0.74 acre), 35% slope. Right for high-end residential properties.
- A 5500 (£4,295): 5,500 m² (≈1.36 acres), 40% slope. Right for mid-size estates.
- A 7500 (£6,495): 7,500 m² (≈1.85 acres), 50% slope. Right for large country estates and small commercial.
For sites under 0.74 acres, the A 3000 is the right call. For sites approaching 2 acres, step up to the A 7500. The A 5500 hits the sweet spot for the broad middle of UK estate-lawn profiles.
The tradeoff
The 12-18 week initial setup window applies to all wireless RTK robotic systems, including the A 5500. RTK-base-station siting, app-based mapping, edge-case training, operator familiarisation. After commissioning, ongoing overhead is software updates, occasional GPS-correction issues, regular sensor cleaning. For sites where IT-and-software overhead is genuinely a deal-breaker, the older perimeter-cable robotic systems are simpler to live with — but the wireless A-series is functionally superior across nearly every operational metric.
