SILENO smart sense 600 m²

User-replaceable with common tools, and an official replacement battery is sold

Operator's manual gives a user procedure (six Torx 20 screws, unclip, two connectors). The original 18V 4.0Ah battery is in Gardena's Spanish parts catalogue and the genuine part is sold by a Spanish retailer (197 €).

At least 80% of key modules sold through official channels

Gardena's Spanish site publishes a spare-parts catalogue for this exact model covering 9 of 10 key modules (battery, cutting disc, blades, drive wheel, cutting motor kit, charging plate wiring, body, main board, camera module); no separate wheel motor is listed. Parts are ordered via Gardena dealers ('Buscar tienda'), not an online cart.

At least half of key modules orderable for a model in the category launched 5+ years ago, including the battery

GPLshop.es (Husqvarna/Gardena robotic-mower parts dealer, EUR checkout, ships to Spain) lists in-stock parts for the SILENO city 2018 model year: battery, cutting disc, cutting system, wheel motor, wheel, top cover/body, main PCB. 7 of 9 applicable modules (78%); blades not verified as listed for this model on an official channel; charging contacts not identifiable (only 'Estación de carga (lower)'). Positioning module N/A (wire-guided).

Partial (e.g. videos for some parts only)

Public operator's manual covers battery, blade and body removal, and exploded parts drawings are public per model; no service/workshop manual for key modules (motors, mainboard) is published.

Neither, or not disclosed

Gardena's warranty is conditional on nobody having opened or repaired the product and on original parts only; parts pairing is not disclosed.

None stated

None stated. The manual only says Gardena updates firmware 'regularly'; Gardena UK lists PSTI statements for smart gateway/water products but none for SILENO mowers.

No evidence of updates for models 2+ years old

Gardena's firmware page shows the latest bundles for older mowers dated 5/2023 (SILENO city, life, minimo) and 12/2021 (R models); SILENO pro/max last 07/2025. Only the 2025 SILENO free and 2026 sense got 2026 bundles.

Statutory guarantee only

3 years with registration only matches Spain's statutory guarantee; batteries excluded.

Core function stops without the manufacturer's cloud

Setup, zones and schedules need the cloud app with a Husqvarna Group account, and navigation relies on correction data delivered over mobile/Wi-Fi; 'no correction data available' is a fault state that needs the service. The keypad can start/park on the stored schedule, but positioning depends on Gardena's correction service. No subscription is needed (lifetime free SIM).

Cloud-only integrations

No Matter certification or official local API found; Gardena's API is cloud-based, and Home Assistant's local Gardena Bluetooth integration explicitly does not support mowers.

Nothing advertised at purchase sits behind a subscription

Gardena advertises no hidden costs and a built-in SIM with permanently free mobile connectivity; RTK corrections and app control carry no subscription.

None

No published commitment on what happens if the GARDENA smart system cloud / correction service is shut down.

At most 10% (robot vacuums: 20%)

€64.46/year in official consumables = 5.9% of €1099.99.

At most 20%

Official battery €197.00 = 17.9% of €1099.99.

They work, but with warnings or reduced function

No chips/DRM on blades and third-party blade kits are sold for Gardena robots, but Gardena warns safety is only guaranteed with original blades and the warranty requires original wear parts.

One of the two

Husqvarna Group (GARDENA owner; the sense manual and app account are Husqvarna Group) published a product vulnerability disclosure policy with web form and productsecurity@ email, covering products developed or maintained by Husqvarna Group. No public advisories, so fix-within-90-days cannot be shown.

Processed on the device; not uploaded by default

Gardena states all camera recordings stay on the mower and cannot be accessed externally or via the cloud.

Neither

Husqvarna Group privacy notice describes deletion on request per service (Group ID stays active), not in-app deletion; it shares pseudonymised account data with advertising partners on marketing consent and does not state that device data is excluded from advertising.
