What each robot actually costs to own
Purchase price plus documented consumables, subscription gating, and replacement events. Bars share one dollar scale, so length is directly comparable. Costs are typical, drawn from manufacturer maintenance guides and owner reports.

Documented failure events
When things break, and what they cost
Field-reported failures placed on the ownership timeline, with associated repair or replacement costs. Sourced from owner forums and manufacturer service documentation.
Charging dock contact corrosion in wet climates
$0-30 (cleaning or contact replacement)Owner reports from Husqvarna Communities document dock contact corrosion appearing in the first full season in high-humidity or high-rainfall regions. Grass debris and moisture accumulate at the contact points; cleaning resolves most cases within 30 minutes. Persistent corrosion requires contact pad replacement.
Perimeter wire break at surface crossing
$10-25 (splice kit)European mower community reports identify surface-mounted wire sections at gate crossings and garden paths as the most common break point for compact wire-guided platforms. DIY splice kits resolve the issue; buried wire sections show substantially lower break frequency.
Boundary wire break: professional trace and repair
$150-400 (professional service)The 430XH's larger coverage area (up to 3,200 sq m) means substantially longer wire runs, which increases the probability of a break from landscaping activity, freeze-thaw soil movement, or rodent damage. Owner reports from r/automower describe professional tracing and repair when break location cannot be identified by tone generator.
Blade disc wear requiring replacement
$10-25 (replacement blade disc)Owner forum aggregates across the Stihl iMow line identify gradual cut quality decline as the primary indicator of blade wear. Rocks and exposed roots can cause sudden breakage; deferred replacement stresses the drive motor. Replacement blade discs are available through Stihl dealer network.
Parts sourcing friction outside European dealer network
Varies (lead time 2-6 weeks, shipping costs)Zucchetti's dealer and parts network is concentrated in Europe; North American and Australian owners report extended lead times for non-consumable parts. Owner community posts describe weeks-long waits for charging dock components and drive assemblies compared to same-week availability from Husqvarna and Stihl authorized service centers.
Charging dock replacement at end of typical wear cycle
$200-350 (dock replacement)Manufacturer documentation and owner reports identify dock replacement as the primary multi-year capital event for the Automower 305, with a typical wear cycle of two to three years under normal seasonal use. Husqvarna's authorized service network provides direct replacement; dock design stability across model years means compatible parts remain available.
Consumables breakdown
Annual cost by part type
Read from each robot’s own record, not restated here. A part is priced only from the manufacturer’s published price for a part its own page lists for that machine, and costed only where a replacement interval has been established. Anything else is left unpriced rather than estimated.
