Quick Answer: The Husqvarna Automower 550 is a large-lawn robotic mower covering 1.25 acres (±20%) at $3,299.99, per thepowertoolstore.com — but the “550” name actually spans four variants that are easy to confuse: the boundary-wire 550 and commercial-deck 550H (both $3,299.99, buried-wire GPS navigation), and the wire-free 550 EPOS and 550H EPOS (satellite RTK-GNSS, no wire, priced from roughly $5,000+, per AllMachines). Buy the plain 550 for a large residential lawn on a budget; step up to EPOS only if trenching a boundary wire genuinely isn’t an option and you’re willing to pay the premium for it.
Husqvarna’s Automower naming gets confusing fast once you hit the 500-series — “550,” “550H,” and “EPOS” all describe real, currently-sold machines with meaningfully different prices and installs, but retailer listings rarely explain how they relate. This page decodes the lineup with real numbers: what each variant actually costs, what the “H” and “EPOS” suffixes change, and which one fits a large lawn versus a light-commercial property. It’s the same wire-free EPOS platform covered in our Husqvarna CEORA review and best commercial robot lawn mower guide, scaled down to a more accessible price point.

Automower 550 — the large-lawn boundary-wire pick
Husqvarna Automower 550
- Covers 1.25 acres (±20% depending on lawn shape and obstacles), per Husqvarna's spec sheet.
- GPS-assisted Pentasearch navigation finds its way back to the charging dock efficiently after low-battery interruptions.
- Climbs slopes up to 45% (24°) inside the boundary, with a 9.45-inch cutting width and 3 pivoting carbon-steel blades.
- 10 Ah Li-Ion battery runs about 270 minutes per charge with a 60-minute recharge time.
- Includes GPS theft tracking, Bluetooth and cellular connectivity, and a 33-ft low-voltage boundary cable for install.
At $3,299.99, the 550 sits well above Husqvarna’s mid-range iQ series but far below the wire-free EPOS or CEORA tiers — it’s the pick for a large residential lawn where trenching a one-time boundary wire is an acceptable trade for a lower price and the buried-wire reliability that doesn’t depend on satellite signal.

550 vs 550H — same price, different blade deck
The plain 550 and the 550H share identical navigation, coverage, and slope numbers — the difference is the cutting deck. The 550H swaps in a 5-blade commercial-grade deck (versus the 550’s 3 blades), aimed at light-commercial and professional-grounds buyers who want a heavier-duty cut on demanding turf, while retailer pricing shows both at the same $3,299.99. For a purely residential lawn, the standard 550 covers the same ground for the same money; the 550H only makes sense if you specifically want the commercial blade hardware.
When EPOS is worth the jump
Both the 550 and 550H are also sold in EPOS trims that trade the buried boundary wire for Husqvarna’s satellite-based RTK-GNSS positioning — the same wire-free technology used across the residential iQ line and scaled up on the Husqvarna CEORA. Instead of trenching a wire, you install a fixed EPOS reference station and draw virtual boundaries in the Fleet Services app, which makes redrawing zones around new flowerbeds or construction a software change rather than a digging job. That flexibility costs real money: AllMachines lists the 550 EPOS at $5,000–$5,830, and Husqvarna’s own product page for the 550H EPOS doesn’t publish a price at all — expect a similar or higher figure once a dealer quotes the reference station and install. Unless you specifically need to reconfigure boundaries often or can’t legally or physically bury a wire, the plain wire-based 550 covers the same acreage for roughly $1,700+ less.
Automower 550 by the numbers
- $3,299.99: Confirmed retail price for both the boundary-wire 550 and 550H, per thepowertoolstore.com — the entry point into the 550 family.
- 1.25 acres (±20%): Husqvarna’s rated coverage for the boundary-wire 550/550H and the EPOS 550H’s standard setting; the EPOS 550H’s maximum capacity rises to 2.5 acres (10,000 m²).
- 45% (24°) slope: The shared slope ceiling across every 550-series variant, dropping to 15% specifically at the boundary line on the EPOS models.
- $1,700–$2,500 EPOS premium: The gap between the wire-based 550’s $3,299.99 and the wire-free 550 EPOS’s $5,000–$5,830, per AllMachines — the cost of eliminating the buried boundary wire.
The bottom line
For most large residential lawns, the boundary-wire Husqvarna Automower 550 is the better buy: 1.25-acre coverage, 45% slope handling, and reliable buried-wire navigation for $3,299.99. Choose the 550H only if you specifically want its commercial 5-blade deck at the same price, and reserve the EPOS variants for properties where a buried wire genuinely isn’t workable and the roughly $1,700+ premium is worth the wire-free flexibility.
