Verdict
Pros & cons
Der Dolphin Nautilus CC Plus ist ein schlichter Kabelroboter für Einbaubecken bis 12 m, der Boden und Wände ordentlich reinigt. Die Wasserlinie bleibt Handarbeit, und an Treppen und Sitzbänken fährt er sich fest. Weil die Siebkartuschen Pollen und Algen durchlassen, gehört der Ultrafeinfilter gleich dazu.
Pros
- Entfernt Sand und abgesetzten Staub vom Boden zuverlässig
- Erfasst in gepflegten Becken etwa 90 % des Bodens pro Lauf
- Klettert Wände hoch, in mehreren Becken auch um Ecken
- Zeitplan am Netzteil ohne App: täglich, jeden zweiten oder dritten Tag
- Für Beton, Folie, Polyester, Fliesen und Salzwasser bis 5.000 ppm freigegeben
Cons
- Fährt sich an Treppen und Sitzbänken fest, teils für den ganzen Lauf
- Reinigt die Wasserlinie nicht, der Rand muss von Hand gebürstet werden
- Serienfilter lässt Pollen und Algen durch, Wasser bleibt nach dem Lauf trüb
- Schwimmkabel fiel nach zweieinhalb bis fünf Jahren mehrfach aus
- Kleine Kartuschen ohne Voll-Anzeige, bei Laub schnell voll
Der Dreame J1 ist ein schwimmender Solar-Skimmer, der Laub und Insekten von der Oberfläche fischt und die Wasserlinie bürstet – Boden und Wände erreicht er nie. Als Ergänzung zum Bodenroboter in einem sonnigen, windgeschützten Becken erspart er dir das tägliche Keschern. Der Haken: Die Umwälzpumpe muss aus sein, sonst treibt er ab, und Propellerfehler erzwingen Neustarts.
Pros
- Hält Wasseroberfläche frei von Blättern und Insekten, Kescher wird seltener nötig
- Bürstet die Wasserlinie mit zwei Seitenbürsten in eigenem Randmodus
- Filterkorb mit 5 l und 200 µm hält Laub, Haare und Insekten zurück
- 18-W-Solarpanel lädt bei Sonne nach, Skimmer sucht selbst die hellste Stelle
- Parkt per App am Beckenrand, bleibt während der Fahrt erreichbar
- Fach für Chlortabletten im Filterkorb
Cons
- Umwälzpumpe muss aus sein, sonst treibt der Skimmer durchs Becken
- Propellerfehler stoppen das Gerät wiederholt, Neustart nötig
- Wind bringt ihn vom Kurs und stört die geordnete Bahn
- Kann sich im Einlauf-Skimmer des Beckens festsetzen
- Geordnete S-Bahn nur im versteckten Labor-Modus der App
