Are there any ongoing costs with the Automower 310E NERA, such as a subscription?

There's no subscription. Husqvarna says the cloud RTK correction data used by the wire-free Husqvarna Automower 310E NERA is provided at no extra cost, and the Automower Connect app is free to use.

The regular cost is blades. Because of the EdgeCut disc at the back, the 310E NERA has two cutting discs with pivoting razor blades, so there are more blades to replace than on a single-disc mower. Husqvarna doesn't make the total blade count clear. Husqvarna sells several blade types that fit it; see our blades guide for how often to change them.

Other costs are optional. A dealer-fitted Connect Kit adds cellular connectivity, the EPOS RS1 reference station covers lawns without internet coverage, and an Automower House protects the mower from sun and rain. Electricity use is small; our running costs calculator gives an estimate. Husqvarna's warranty is 2 years for consumers, and dealer servicing is charged separately.
