Verdict

Pros & cons

Der Beatbot AquaSense 2 Pro ist ein kabelloser Poolroboter auf Raupen, der Boden, Wände, Wasserlinie und Oberfläche reinigt. Er verweilt an der Wasserlinie und schrubbt sie doppelt, eine Ladung reicht für mehrere Stunden. Für große Einbaupools mit Fliesen oder Folie ist er eine sehr gute Wahl. Der Haken: Laub schiebt der Skimmer-Modus oft weg, und rund 11 kg wollen aus dem Becken gehoben werden.

Pros

  • Schrubbt die Wasserlinie zweimal im N-Muster, Algenspuren verschwinden sichtbar
  • Lief im Pro-Modus über 3 h und deckte mehr als 110 m² ab
  • Taucht am Ende auf und pumpt das Wasser per SmartDrain ab
  • Umfährt eine frei hängende Poolleiter, ohne sich zu verkeilen
  • Filterkorb mit 3,7 l und Falltür-Boden in wenigen Minuten gespült
  • Reinigt auch ovale und runde Becken samt Rundungen vollständig

Cons

  • Skimmer-Modus drückt Blätter mit dem eigenen Wasserstrahl seitlich weg
  • Rund 11 kg schwer, über hohe Beckenränder teils nur zu zweit
  • Kleine oder geschwungene Stufen bleiben ungereinigt
  • In Becken mit mehreren Ecken teils zwei Läufe nötig
  • Sinkt nach etwa 20 min an der Oberfläche wieder ab

Der Dolphin E40i ist ein Kabelroboter für Einbaubecken bis 12 m, der Boden, Wände und Wasserlinie gründlich und in geplanten Bahnen reinigt. Sein Mehrwert ist der Wochenplan per App, der aber stabiles WLAN am Becken voraussetzt. Treppen bleiben Handarbeit, eine Filteranzeige fehlt, und vollgesogen wird das Gerät beim Herausheben schwer. Ohne App-Nutzung reicht dir ein Modell darunter.

Pros

  • Reinigt Boden, Wände und Wasserlinie gründlich in einem Lauf
  • Startet per App-Wochenplan selbstständig zu festen Zeiten
  • Systematische Bahnen mit Gyroskop decken die Fläche gleichmäßig ab
  • Filterkorb lässt sich von oben entnehmen, ohne das Gerät zu drehen
  • Drehgelenk am 17 bis 18 m langen Kabel verhindert Verdrillen
  • Start auch ohne Smartphone direkt am Netzteil möglich

Cons

  • Treppen und Stufen reinigt er nicht
  • App-Einrichtung und Verbindungsaufbau brauchen Geduld, WLAN am Becken nötig
  • Keine Anzeige für den vollen Filter
  • Vollgesogen beim Herausheben schwer, bei 7,5 bis 7,9 kg Leergewicht
  • Festsitzender Algenbelag an Folienwänden bleibt teils haften
