Verdict
Pros & cons
Der Beatbot iSkim Ultra ist ein solarbetriebener Oberflächen-Skimmer, der Pollen, Insekten und kleine Blätter zuverlässig aus dem Wasser holt und bei Sonne praktisch ohne Pause fährt. Am meisten bringt er an offenen Becken unter Laubbäumen ohne gut arbeitenden Einbau-Skimmer. Der Haken: Große Blätter treiben oft weg, und für das Leeren des Korbs musst du das 7,7 kg schwere Gerät herausheben.
Pros
- Läuft bei Sonne dauerhaft, Akku blieb über Monate über 85 %
- Holt Pollen, Insekten und kleine Blätter fast vollständig ein
- Großer 9-l-Korb, bei viel Laub nur alle drei Tage leeren
- Planvolle S-Bahnen mit Ultraschall-Randerkennung
- Ausziehbare Bügel verhindern Aufsetzen an Stufen und Sonnenbänken
- Manuelle App-Steuerung für Laubnester, stabile WLAN-Verbindung
Cons
- Große Blätter treiben seitlich weg, nur 40 bis 45 % Kunstlaub eingesammelt
- Korb nur nach Herausheben des 7,7 kg schweren Geräts erreichbar
- Kleine Propeller, Sog lässt bei Wind nach
- An bewölkten Herbsttagen teils nur etwa 3 h Betrieb
- Klärmittel-Spender bei ausgeglichener Wasserchemie ohne erkennbaren Nutzen
WYBOT C187
Der WYBOT C1 ist ein kabelloser Poolroboter auf Raupen, der Wände bis zur Wasserlinie gründlich reinigt und Laub, Insekten und groben Schmutz zuverlässig vom Boden holt. Er passt zu Folien- und Betonbecken bis 150 m². Feiner Sand geht durch den 180-µm-Filter, am Boden bleiben kleine Stellen liegen, und mehrere Geräte fielen nach Monaten aus.
Pros
- Reinigt Wände sauber bis zur Wasserlinie und saugt dort Insekten ab
- Holt Laub, Insekten und groben Schmutz zuverlässig vom Boden
- 120 bis 150 min Laufzeit, reicht für Becken bis etwa 6 m Länge
- Zyklustimer verteilt eine Akkuladung auf bis zu vier Läufe in einer Woche
- In rund fünf Minuten samt Firmware-Update eingerichtet
- Parkt nach dem Lauf an der Wand, Bergung per Haken und Poolstange
Cons
- Mehrere Geräte ließen sich nach Wochen oder Monaten nicht mehr einschalten
- Feiner Sand und Schmutzpartikel gehen durch den 180-µm-Filter
- Lässt am Boden kleine Stellen, Innenecken und kleine Stufen aus
- Rutscht auf Fliesen, Acryl und glatter Folie ohne Schwimmkörper von der Wand
- Programmwahl nur per App, Kopplung scheiterte mit einzelnen Handys
