Husqvarna Automower 420 iQ, Wire-Free Robotic Mower for Large Residential Lawns

The Husqvarna Automower 420 iQ is a premium wire-free robotic lawn mower designed for larger lawns up to 4,000 m². Powered by Husqvarna EPOS technology, it gives U.S. homeowners a flexible, accurate and highly convenient way to maintain bigger residential lawns without relying on a traditional boundary wire.

With virtual boundaries, selectable mowing patterns, radar object detection and Automower Connect app control, the 420 iQ is ideal for larger suburban blocks, lifestyle properties and open lawn areas where presentation, flexibility and reliable daily mowing matter.

Ideal for

Large residential lawns up to 4,000 m²
Lifestyle properties and larger suburban blocks
Homeowners wanting a wire-free robotic mowing setup
Lawns with multiple zones, garden beds, paths or outdoor areas
Customers who want stripe, checkerboard, triangle or irregular mowing patterns
Properties where flexible virtual boundaries and stay-out zones are useful

More lawn, no boundary wire limits

The Automower 420 iQ is designed for larger properties, covering up to 4,000 m² in systematic mowing mode or up to 2,000 m² in irregular mowing mode. It is a strong step up for customers who need more capacity than smaller residential robotic mowers can provide.

Using Husqvarna EPOS technology, the mower can operate with virtual boundaries created in the Automower Connect app. This allows work areas, stay-out zones and mowing patterns to be adjusted digitally as your lawn or garden layout changes.

Cloud positioning or included RS1 reference station

The Automower 420 iQ can use Husqvarna Cloud positioning where coverage is available. If your property is outside cloud coverage, the included EPOS RS1 reference station can be used as a stand-alone positioning solution.

For large, complex or sloped properties, professional installation by an authorised Husqvarna dealer is recommended to help achieve the best possible setup and mowing result.

Installation note

Wire-free operation depends on correct EPOS planning, suitable satellite visibility and proper setup. Physical boundary wire installation is also available if preferred or if it better suits the property.

Mow your way

Choose from striped, checkerboard, triangular or irregular mowing patterns to suit the look you want for your lawn. Electric cutting height adjustment allows the mower to cut from 25 mm to 100 mm, making it suitable for different grass types, seasons and lawn preferences.
