Husqvarna Automower 440iQ Robotic Mower, 2 Acre Mowing Capacity, Wire Free Robot Lawn Mower with Charging Station, RS1 EPOS Reference Station and Replacement Blades

What It Is

This is the complete Husqvarna Automower 440iQ system—a wire-free robotic mower designed for up to 2 acres, including the charging station, RS1 EPOS reference station, and replacement blades. It’s for residential users wanting a GPS-guided mower that doesn’t require boundary wires.

Fitment & Compatibility

• Model-specific: This is the full 440iQ system, not a standalone part or accessory. It works only with the included RS1 EPOS reference station for satellite navigation—no boundary wire needed.
• Deck & terrain: The mower has a 9-inch cutting width and handles slopes up to 20 degrees. Ensure your lawn is relatively open (minimal tree canopy) for strong GPS signal; dense overhead cover can degrade EPOS accuracy.
• OEM vs aftermarket: All components are OEM Husqvarna. Replacement blades are standard 440iQ blades (Husqvarna part # 590 83 87-01). Do not use non-OEM blades—they can damage the cutting disc.
• What to check before buying: Verify your lawn is within 2 acres and has clear sky visibility for the reference station. The RS1 must be placed in a fixed outdoor location with a power source and within 1,000 feet of the mowing area.

Key Things to Know

• Installation difficulty: Moderate to high. You must mount the RS1 reference station (tripod or pole), configure the GPS boundary via the Automower Connect app, and perform initial mapping. Expect 1–3 hours for setup.
• Signal reliability: EPOS relies on GPS and the reference station. Heavy rain, tall trees, or buildings can cause temporary signal loss, leading to missed spots or pausing.
• Maintenance: Replace blades every 4–6 weeks for clean cuts. The mower self-charges, but the RS1 station needs occasional cleaning of its antenna dome.
• Common gotcha: If your lawn has narrow passages (<4 feet wide), the mower may struggle to navigate wire-free. Also, the 440iQ does not include a weather sensor—it may mow in light rain, which can leave clumps.

Should You Buy It

Buy this if you have a 1–2 acre open lawn, want to avoid laying boundary wire, and are comfortable with tech setup and GPS reliance. Skip it if your yard has heavy tree cover, narrow paths, or you want a simpler plug-and-mow experience—a wired Automower is cheaper and more reliable in those conditions.
