Verdict

Pros & cons

Der Dolphin Liberty 300 ist ein Akku-Roboter auf Raupen, der Boden und Wände gründlich reinigt – ohne Kabel und ohne App, bedient über eine Taste. Er passt zu schlichten Folien-, Beton- oder Polyesterbecken bis 10 m, die Bergung per Klicker erspart meist den Haken. Der Haken: Fahrwege ohne System lassen Stellen aus, und die Wasserlinie streift er nur. Auf Fliesen fehlt den Raupen der Halt.

Pros

  • Reinigt Boden und Wände eines 10 x 4 m Beckens in 90 min
  • Feinste Filterplatten halten Partikel bis 50 µm zurück
  • Klicker holt den Roboter an die Wasserlinie, kein Haken nötig
  • Eco-Modus pflegt den Boden eine Woche lang alle 48 h
  • Einfache Bedienung über eine Taste, Programmwahl unter 10 s
  • Ohne Kabel nutzbar auch bei geschlossenem Rollladen

Cons

  • Fährt ohne erkennbares System, lässt Stellen aus
  • Wasserlinie wird nur gestreift, nicht geschrubbt
  • Raupen rutschen auf Fliesen durch, Klettern scheitert
  • Akku fest verbaut und nicht austauschbar
  • Keine App, kein Wochenplan und keine Nachricht zum Laufende

Der Zodiac CNX 50 iQ ist ein Kabelroboter auf Raupen, der Boden und Wände gründlich und systematisch reinigt und sich per Lift System an der Wasserlinie ohne Haken bergen lässt. Für verwinkelte Becken bis 12 m taugt er, wenn du die Kabelführung sorgfältig einrichtest. Der Haken: Treppenstufen lässt er aus, und die App bietet weder Wochenplan noch Reinigungsverlauf.

Pros

  • Reinigt Boden und Wände gründlich, auch auf unebenem Beckengrund
  • Zweistufiger Filterkorb mit 4 l trennt Grobes und Feines bis 60 µm
  • Lift System parkt ihn an der Wasserlinie und stößt beim Herausheben Wasser aus
  • Filter oben unter einer Klappe, Entnahme ohne Umdrehen des Roboters
  • 18 m Kabel mit Drehgelenk reicht für Becken bis 12 m

Cons

  • Treppenstufen steigt er nicht hoch, dort bleibt die Handbürste nötig
  • App ohne Wochenplan und Reinigungsverlauf, WLAN nur im 2,4-GHz-Band
  • Abdeckung hängt stark vom Kabelverlauf und von der Einsetzstelle ab
  • Bleibt nach Programmende stehen, auch mitten im Becken
  • Ein abgebrochenes Programm beginnt beim nächsten Start von vorn
