Budget for a robot mower’s installation and running costs as well as its purchase price. The main items are electricity, blades, servicing, eventual battery replacement and any connectivity or positioning equipment the chosen model needs. Obtain current quotes for your garden rather than assuming these costs are the same across all mowers.

Ask for a complete installation quote

For a wired system, check whether the price includes enough boundary and guide wire, connectors, pegs and installation labour. For a wire-free system, check whether the required positioning module, reference station, mount or connectivity equipment is included.

A site survey may identify necessary changes to a dock position, passage or boundary. Keep optional accessories separate from equipment required for operation. More expensive hardware cannot make a model suitable for a slope or route beyond its approved limits.

Allow for consumables and electricity

Cost	What to ask
Blades and fixings	Price of the approved full replacement set and expected inspection frequency for your lawn
Electricity	Estimated consumption under the intended schedule, including charging and standby where stated
Battery	Current replacement price, fitting arrangements and warranty conditions
Wear and installation repairs	Typical parts availability and charges for wheels, cables, connectors or damaged equipment

Blade life varies with mowing time, grass, soil and contact with debris. The number of blades included in a service contract is not a prediction of how many your lawn will need. Batteries also have no universal replacement date; workload, age and storage affect their condition.

For an electricity estimate, multiply the manufacturer’s relevant energy-use figure in kilowatt-hours by your tariff per kilowatt-hour. Keep the period consistent and label the result as an estimate; do not confuse charger wattage with energy used over a month.

Compare servicing and storage options

Ask what an annual service includes: diagnostics, cleaning, safety checks, consumables, collection and storage may be priced separately. Check the maintenance required by the warranty and which work the owner can do.

For a service plan, read exclusions, length of cover and claim conditions as well as the monthly price. Winter charging and storage requirements vary by model. A generic promise to charge every mower twice over winter is not a substitute for the operator’s manual.

Check connectivity terms

Separate optional remote app access from connectivity required for navigation. A mower using cloud correction data may depend on network coverage across the working area; another installation may use a local reference station instead.

Husqvarna’s published Automower Connect terms describe included connectivity for a stated period, subject to network support and coverage. Confirm the current terms for the exact model and market, what happens after the included period, and whether dealer-installed hardware or a different SIM arrangement would cost extra. Other brands can have different subscriptions.

A reference station does not automatically solve satellite obstruction beneath trees. Confirm the actual cause of weak coverage and the model’s supported solution before purchasing extra equipment.

Compare total cost over the same period

Use the same ownership period for each shortlisted mower. Add purchase, necessary installation, estimated electricity and blades, quoted servicing and subscriptions, then show possible battery or repair costs separately. This keeps uncertain future repairs distinct from committed fees.

Include your own practical workload too: manual edge trimming, carrying the mower to a separate lawn and clearing obstructions can remain part of ownership. Choose on the basis of a workable installation and support arrangements, not the purchase price alone.
