Verdict
Pros & cons
Der Aiper Scuba S1 ist ein kabelloser Raupenroboter für Boden, Wände und Wasserlinie, der vor allem den Boden gründlich reinigt. Eine Akkuladung reicht für gut 2,5 h, danach dauert das Nachladen 3 bis 4 h. Für eckige und ovale Gartenbecken ohne Treppenanlage taugt er gut. Breite Stufen, Leitern und viel Laub bremsen ihn, und unter Wasser lässt sich ein laufendes Programm nicht ändern.
Pros
- Boden nach einem vollen Lauf meist restlos sauber, auch feiner Sand und Haare
- Schrubbt die Wasserlinie bis etwa 4 bis 5 cm über der Oberkante
- Kabellos mit gut 2,5 h Laufzeit pro Ladung in der Praxis
- MicroMesh-Feinfilter mit 3 µm holt Staub und Algenreste aus dem Wasser
- Mit 7,7 kg leicht, Wasser läuft beim Herausheben ab
- Eco-Modus reinigt in der Urlaubswoche alle 48 h den Boden
Cons
- Hängt an breiten Treppen und Leitern fest, meldet blockierte Kette
- Kommt in kleinen Rundbecken die gekrümmte Wand schlecht hoch
- Bei viel Laub sind drei bis vier Läufe mit Bergen und Laden nötig
- Laufendes Programm lässt sich unter Wasser weder ändern noch stoppen
- Filterkorb schließt bei einzelnen Geräten nicht dicht, Schmutz fällt zurück
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
