Verdict
Pros & cons
Der Beatbot Sora 30 ist ein kabelloser Raupenroboter, der Boden und Wände gründlich von Laub und Sand befreit und im Standardmodus rund 4,5 h durchhält. Für einfach geformte Becken bis etwa 10 m Länge ist er eine solide Wahl. Der Haken: Ohne Karte lässt er Ecken, Stufen und Plattformen teils aus, und feinen Staub hält der mitgelieferte 150-µm-Korb nicht zurück.
Pros
- Saugt Laub, Sand, Kiesel und Eicheln zuverlässig ein
- Rund 4,5 h Laufzeit im Standardmodus mit Wänden und Wasserlinie
- 5-l-Korb muss auch nach über 4 h nicht geleert werden
- Steigt nach dem Lauf auf, parkt am Rand und lässt Wasser ab
- Klettert sicher an Wänden, auch bei faltiger alter Folie
- Flachwasserreinigung schon ab 20 cm Wassertiefe
Cons
- Ecken und Übergang Boden–Wand bleiben ohne Karte oft ungereinigt
- Breite Stufen und Sonnenplattformen reinigt er nicht systematisch
- 150-µm-Korb lässt Feinstaub durch, 3-µm-Korb nur als Zubehör
- Kein Wochenplan in der App, Einrichtung nur im 2,4-GHz-WLAN
- Wasserlinie nur in kurzen Rucken statt entlang gefahren
Der Dolphin Liberty 400 reinigt Boden, Wände und Wasserlinie ohne Kabel und wartet nach dem Lauf an der Wasserlinie auf den Klicker. In gepflegten Becken mit Folie oder rauem Beton arbeitet er verlässlich und bequem. Der Haken: weniger Sog als Kabelgeräte, ein fest verbauter Akku mit bis zu 6 h Ladezeit und Durchdrehen an glatten Fliesen.
Pros
- Reinigt Boden, Wände und Wasserlinie ohne Schwimmkabel
- Bergung per Klicker bis zu zwei Tage nach Zyklusende
- Induktives Laden per Magnetstecker ohne offene Kontakte
- Eco-Modus verteilt eine Ladung auf 3 x 40 min pro Woche
- Systematische Bahnen per Gyroskop statt Zufallsfahrt
- Filterkorb von oben entnehmbar, Paneele bis 50 µm
Cons
- Raupen drehen auf glatten Fliesen und Mosaik an Wänden durch
- Saugt und schrubbt schwächer als kabelgebundene Dolphin-Modelle
- Akku fest verbaut, bis zu 6 h Ladezeit für einen Zyklus
- Bei viel Schmutz bleiben nach einem Durchgang Reste
- Wasserlinie und Ecken teils ungleichmäßig gereinigt
