## Key Features
### EPOS Wire-Free Boundary System
Like all iQ models, the 420 iQ uses Husqvarna's EPOS (Exact Positioning Operating System) for centimeter-accurate satellite navigation. There is no boundary wire to install — you define work zones, forbidden zones, and passages virtually using the Automower Connect app. This is especially valuable for complex lawns with garden beds, trees, and irregular shapes, where installing a physical wire boundary would be time-consuming and imprecise.
### Full 1-Acre Coverage
The 420 iQ is rated for lawns up to 1.0 acre. For the average American homeowner, this covers the great majority of residential properties. The mower runs in scheduled sessions throughout the day, returning to base when the battery needs charging and resuming automatically — requiring no input from you.
### Automower Connect App — Triple Connectivity
Cellular, WiFi, and Bluetooth connectivity means you are always connected to the 420 iQ regardless of where you are. Schedule sessions, start or stop on demand, check operational history, or receive push notifications if the mower needs attention. The app experience is polished and reliable, placing Husqvarna well ahead of most competitors on the connectivity front.
### 45% Slope Capability
The 420 iQ handles slopes up to 45%, which covers the vast majority of residential terrain including rolling hills and moderate inclines. This makes it a practical choice even for properties that are not entirely flat.
### GPS Theft Protection
Built-in GPS tracking allows you to locate the mower at any time through the app. Combined with a PIN-code requirement for operation, the 420 iQ is one of the most theft-resistant robotic mowers on the market.
### Included Year of Free Blades
Husqvarna includes a complimentary first year of replacement blades with the 420 iQ. Blade replacement is a routine maintenance task for all robotic mowers (typically every 1-2 months depending on conditions), so this inclusion represents real savings and demonstrates Husqvarna's commitment to ownership satisfaction.
