Verdict

Pros & cons

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

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
