Verdict
Pros & cons
Der Dolphin Nautilus CC ist ein schlichter Kabelroboter auf Raupen, der Boden und untere Wände solide sauber bürstet und Laub zuverlässig aufnimmt. Er passt zu dir, wenn dein Becken eben ist und höchstens 10 m lang. Der Haken: kein Timer, kein Drehgelenk. Jeden Lauf startest du von Hand, das Kabel verdreht sich, und die Wasserlinie bleibt Handarbeit mit Bürste.
Pros
- Rotierende Bürsten reinigen den Beckenboden gründlich
- Nimmt Laub, Zweige und Grasschnitt zuverlässig auf
- Gummiraupen klettern auch auf Folie die Wand hoch
- Mit 6,71 kg allein aus dem Wasser zu heben
- Filterkorb ohne Werkzeug zu entnehmen und auszuspülen
- Vormontiert, Start per Knopfdruck ohne Einarbeitung
Cons
- Kabel ohne Drehgelenk verdreht sich, bis der Roboter festsitzt
- Kein Wochentimer, jeder 120-min-Lauf startet von Hand
- Ecken und Bodenstreifen an der Wand bleiben teils schmutzig
- Standardfilter lässt feinen Sand teils durch
- Kabeldefekte und Antriebsausfälle nach ein bis zwei Jahren
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
