Verdict

Pros & cons

Der Dolphin E20 ist ein leichter, leiser Kabelroboter für Boden und Wände, der ordentlich, aber nicht makellos reinigt. Er passt zu kleinen, eckigen Becken bis etwa 8 x 4 m, wenn du die Wasserlinie selbst wischst und gleich einen feineren Filterkorb einplanst. Der Haken: Im Rundpool bleibt der Übergang schmutzig, und App oder Zeitplan fehlen.

Pros

  • Aktive Bürste löst am Boden auch festliegenden Belag, Laub und Algen
  • Klettert an geraden Wänden hoch und bürstet sie mit
  • Mit rund 6,5 kg leicht genug, um ihn allein herauszuheben
  • Filterkorb oben, Wasserablauf beim Herausheben, Ausspülen ohne Schmutzkontakt
  • Läuft leise, neben dem Becken kaum zu hören
  • Feinere Filterkörbe mit 70 und 50 µm als Ersatzteil erhältlich

Cons

  • Reinigt die Wasserlinie nicht, der Rand bleibt Handarbeit
  • Im Rundpool bleibt der Übergang Boden–Wand ungeputzt, Bürste sitzt hinter den Raupen
  • Standardkorb mit 100 µm lässt Schwebstoffe durch, Wasser wird leicht trüb
  • Nach 120 min bleibt Restschmutz, Partikel werden vor dem Gerät hergeschoben
  • Kabel ohne Drehgelenk kann sich verdrillen, kein Zeitplan, keine App

Der Dolphin Liberty 200 ist ein kabelloser Poolroboter, der Boden und Wände ordentlich bürstet. Er passt zu Becken bis 10 m ohne Steckdose in Randnähe, wenn du das Laden in Kauf nimmst: Nach 90 bis 150 min Lauf braucht er bis zu 6 h am Ladegerät. Die Wasserlinie reinigt er nicht verlässlich, App und Zeitplan fehlen, und geborgen wird er mühsam per Haken.

Pros

  • Kein Kabel im Becken, induktive Ladestation ohne offene Kontakte
  • Aktivbürste schrubbt Boden und Wände gründlich ab
  • Plant die Route systematisch statt nach Zufall
  • Eco-Modus reinigt eine Woche lang den Boden, dreimal je 40 min
  • Fein- und Ultrafein-Paneele schon im Lieferumfang
  • Verträgt Salzwasser bis 5.000 ppm, für Folie, Beton und Polyester

Cons

  • Wasserlinie wird nicht verlässlich gereinigt
  • Bis zu 6 h Ladezeit nach 90 bis 150 min Lauf
  • Keine App und kein Zeitplan, jeder Lauf startet per Knopf
  • Bergung nur per Haken, vollgesogen schwerer als 8,1 kg
  • Saugt schwächer als vergleichbare Kabelgeräte, kein Laubsack erhältlich
