FAQ
Can the Husqvarna 420 IQ work in the rain?
Yes. It boasts an excellent all-weather waterproof design.
However, in extreme downpours, it’s recommended to use the app to have it return to its charging dock to prevent excessive trampling of the grass roots.
Is Satellite Navigation (EPOS™) really better than wired wiring?
In most cases, yes. EPOS™ eliminates the installation costs and maintenance hassles of aging wiring, making it ideal for large or complex gardens.
What if there are pets or children on the lawn?
The 420 IQ is equipped with a sensitive sensor system.
Upon contact with an obstacle or being lifted, the blades immediately stop rotating to ensure safety.
Can a single charge cut 2500㎡ of lawn?
No. A single charge provides approximately 100 minutes of continuous operation.
However, it will automatically return to its charging dock for 60 minutes before resuming operation.
This “small amount, multiple times” cyclical cutting logic can make the lawn grow more evenly.
