Verdict
Pros & cons
Der Beatbot Sora 70 ist ein kabelloser Raupenroboter, der Boden, Wände, Wasserlinie und Oberfläche in einem Gerät reinigt. Treibendes Laub und Pollen landen im 6-l-Korb, bevor sie absinken, und ein Skimmer-Roboter wird überflüssig. Der Haken: Ein kompletter Lauf dauert rund 4,5 h, Ecken und schmale Stufen brauchen weiter die Handbürste. Wenn du abends startest und viel Laub hast, passt er gut.
Pros
- Reinigt Boden, Wände, Wasserlinie und Oberfläche in einem Gerät
- Oberfläche voller Blätter und Insekten nach 10 bis 15 min sauber
- Klettert sicher über den Übergang Boden–Wand bis zur Wasserlinie
- 6-l-Filterkorb nimmt viel Laub, Eicheln und kleine Äste auf
- Taucht auf, parkt am Rand und lässt beim Herausheben Wasser ab
- Bis zu 7 h im Oberflächenmodus, unter Wasser fast lautlos
Cons
- Kompletter Lauf über Boden, Wände und Wasserlinie dauert rund 4,5 h
- Ecken und schmale Stufen bleiben teils schmutzig, Handbürste nötig
- 150-µm-Standardfilter lässt feinen Staub durch, Feinfilter nur optional
- Taucht nach jedem Lauf auf, ungeeignet für Becken mit Rollladen
- Keine Poolkarte, keine Ladestation, rund 10 kg schwer
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
