The Evidence Behind Our Scores
Our Accountability Standard is only credible if the evidence is visible. This page documents the sources, screenshots, and documentation that inform our Reliability Tracker ratings.
🔧 Repairability Evidence
How we determine whether a brand is User-Serviceable, Dealer Recommended, or Manufacturer-Only.
Parts Availability
Husqvarna — User-Serviceable
Official parts catalog publicly available on husqvarna.com. Blade kits, wheel motors, batteries, and charging contacts sold directly to consumers. PartSelect and Amazon carry OEM and aftermarket parts. Repair guides published in owner manuals and YouTube.
Parts Availability
Worx — User-Serviceable
Modular ACS accessory system designed for consumer replacement. Blades, batteries, and modules available on worx.com and major retailers. Community repair guides on YouTube with 50k+ views.
Forum Analysis
Mammotion — Dealer Recommended
Reddit r/mammotion reports indicate blade disc replacement is DIY-friendly, but mainboard and RTK antenna issues require manufacturer RMA. No published repair guides. Parts not sold separately as of March 2026.
👨💻 Developer Access Evidence
How we verify API availability and third-party integration support.
API Documentation
Husqvarna — Open API
Husqvarna Authentication API and Automower Connect API publicly documented at developer.husqvarna.com. OAuth2 authentication. Home Assistant integration official. Active developer community.
API Documentation
Worx — Open API
Worx Landroid API documented through pyWorxCloud Python library. MQTT-based real-time communication. Home Assistant community integration with 1000+ users. Local network access supported.
API Status
Mammotion — Closed
No public API documentation found. App communication uses proprietary protocol. No official Home Assistant support. Community reverse-engineering efforts in early stages (mammotion-ble GitHub).
☁️ Cloud Dependency Evidence
How we test whether mowers function without internet connectivity.
Manufacturer Statement
Kress — Local-First
Kress RTKn technology operates using local RTK base station. Mowing schedules stored on-device. Mobile app required only for initial setup. Confirmed by Kress product documentation and dealer demonstrations.
Owner Reports
Ecovacs GOAT — Cloud-Heavy
Multiple Reddit reports (r/ecovacs) confirm GOAT G1 requires active cloud connection for scheduling changes and zone management. Mower enters standby mode during cloud outages.
Owner Reports
Husqvarna — Hybrid
Automower continues scheduled mowing without internet (schedule stored locally). However, remote start, GPS tracking, and app notifications require Automower Connect cloud service.
📦 Data Portability Evidence
A field where the entire industry falls short.
Industry Finding
ALL BRANDS — No Full Export
As of March 2026, zero brands in our 50-brand database offer full export of yard maps, obstacle data, and mowing history. Some brands (Husqvarna, Worx) allow partial export of schedules and settings, but property mapping data remains locked in manufacturer ecosystems.
Impact Assessment
Switching Cost Estimate
Owner reports estimate 4-8 hours to re-map a property when switching brands — including boundary wire reinstallation (wire-based) or RTK zone remapping (wire-free). This effectively creates vendor lock-in through data hostage.
How to Submit Evidence
We welcome additional evidence from owners, technicians, and manufacturers. Every piece of evidence strengthens our database and improves the accuracy of our ratings.
- Screenshots of app features, offline behavior, or error messages
