Verdict
Pros & cons
Der WORX Landroid Vision Cloud WR303E mäht ohne Draht und ohne Antenne in geordneten Bahnen, die Korrekturdaten kommen über dein WLAN. Für 300 m² taugt er nicht: Der Serienakku schafft pro Ladung keine 100 m², am Rand bleiben 10 bis 15 cm stehen. Dazu kommen Defekte ab Werk, eine zähe Kopplung und ein Support, der wochenlang schweigt. Für kleine, ebene Rasen mit klaren Kanten und viel Geduld.
Pros
- Navigiert ohne Begrenzungsdraht und ohne eigene RTK-Antenne im Garten
- Kein Abo für den Cloud-Korrekturdienst, WLAN nur an der Station nötig
- Gleichmäßige parallele Bahnen, vier Mähmuster und Zeiten je Zone
- Kamera erkennt auch einen flachen Gartenschlauch, Empfindlichkeit einstellbar
- PowerShare-Akku tauschbar, mit 4 Ah rund 250 m² am Stück
Cons
- Serienakku mit 2,5 Ah schafft pro Ladung keine 100 m²
- Mehrere Neugeräte mit defektem Radantrieb, Support antwortet oft wochenlang nicht
- Am Rand bleiben 10 bis 15 cm stehen, auch mit Cut-to-Zero
- Findet die zweite Zone oft nicht oder nicht zurück zur Station
- Bluetooth-Kopplung scheitert häufig, Karte nachträglich nicht bearbeitbar
Der Yard Force MB400 ist ein schlichter Draht-Mäher mit Zufallsfahrt für ebene Rasen bis etwa 300 m². Er mäht dort zuverlässig nach Zeitplan und lässt sich per Tasten oder Bluetooth-App steuern. Der Haken: Durchgänge brauchen mindestens 200 cm Breite, ein Regensensor fehlt, und Buckel bringen ihn aus dem Takt. Für verwinkelte Gärten ist er die falsche Wahl.
Pros
- Läuft auf ebenem Rasen zuverlässig nach festem Zeitplan
- Zeitplan auch ohne App direkt über Tasten am Gerät einstellbar
- Schnitthöhe zentral und stufenlos von 20 bis 55 mm
- Lieferumfang mit 100 m Kabel, Heringen, Ersatzklingen und Abstandslineal
- Drahtnavigation funktioniert auch unter Bäumen und an der Hauswand
- Software-Updates zugesagt bis Oktober 2031
Cons
- Durchgänge zwischen Rasenflächen müssen mindestens 200 cm breit sein
- Kein Regensensor, mäht bei Schauer weiter
- Zufallsfahrt ohne Bahnen lässt verwinkelte Ecken länger stehen
- Bluetooth-App nur in Gerätenähe, kein WLAN oder Fernzugriff
- Unebenheiten wie Buckel und Löcher führen zu Störungen
