Verdict
Pros & cons
Der BWT COSMY 200 ist ein leichter Kabelroboter für Einbaubecken bis 10 m, der Boden, Wände und Wasserlinie gründlich und in geordneten Bahnen reinigt. Mit 5,7 kg und Schnellablauf hebst du ihn ohne Kraftakt aus dem Becken. Der Haken: Der Filterkorb hält erst Schmutz ab 150 µm zurück, ein Feinfilter ist nicht erhältlich, Pollen und Staub bleiben der Filteranlage überlassen.
Pros
- Schrubbt an der Wasserlinie, statt nur kurz anzustoßen
- Fährt per Gyroskop geordnete Bahnen, auch Ecken und Nischen
- Mit 5,7 kg leicht, Schnellablauf lässt beim Anheben Wasser ab
- Filterkorb per Knopfdruck von oben entnehmbar, mit Voll-Anzeige
- Intervall-Zeitplan alle 48, 72 oder 96 h über die App
- Ersatzteile wie Ketten, Bürsten und Kabel einzeln lieferbar
Cons
- Filter hält nur Schmutz ab 150 µm, kein Feinfilter erhältlich
- App nur per Bluetooth in Reichweite des Netzteils
- Kein Zeitplan mit festen Wochentagen, nur Intervall
- Stufen und Treppen schafft er nicht verlässlich
- Bleibt nach dem Lauf am Boden, in tiefen Becken Haken nötig
WYBOT C281
Der WYBOT C2 ist ein kabelloser Raupen-Roboter, der Boden, Wände und Wasserlinie gründlich reinigt, auch auf Folie. Für Becken um 25 m² taugt er gut, der 10-µm-Feinfilter holt Sand und Algenreste. Der Haken: real rund zwei Stunden Akku, im Vollpool-Modus verliert er die Ordnung, und der Zeitplan verteilt nur eine Ladung auf mehrere Tage.
Pros
- Reinigt Boden, Wände und Wasserlinie in einem Lauf, auch auf Folie
- Gummiwalze schrubbt die Wasserlinie ab, kein Schmutzrand bleibt
- Beiliegender 10-µm-Feinfilter holt feinen Sand und Algenreste
- Tastet sich an Düsen, Skimmer und Licht heran, ohne hängen zu bleiben
- Parkt nach dem Lauf meist am Beckenrand, 7,9 kg leicht
- Im Betrieb kaum zu hören, Filterkorb leicht zu leeren
Cons
- Akku hält real rund 120 min, nur Öko-Boden schafft 180 min
- Zeitplan teilt eine Ladung auf bis zu vier Tage, nur Boden
- Im Vollpool-Modus kein festes Muster, in Rundbecken bleiben Zonen schmutzig
- Feinfilter setzt sich in schmutzigem Wasser schnell zu
- Fest verbauter Akku verlor in einzelnen Fällen früh Kapazität
