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
Der Dreame Z1 Pro ist ein kabelloser Raupen-Roboter für Boden, Wände und Wasserlinie, der Boden und Wände gründlich reinigt. Er passt zu einfachen Becken mit klarem Wasser und wenigen Einbauten. Der Haken: Fehlerabbrüche, Hängenbleiben an Leitern und Rollabdeckungen sowie ein Ergebnis, das stark von der Firmware abhängt.
Pros
- Reinigt Boden und Wände gründlich, Boden nach rund 30 min meist sauber
- Fährt das Becken nach Kartierung systematisch in geraden Bahnen ab
- Knapp 3 h Komplettreinigung im Leistungsmodus mit einer Ladung
- LiFi-Fernbedienung steuert den Roboter auch während des Laufs unter Wasser
- Wartet an der Wasserlinie und pumpt vor dem Herausheben Wasser ab
- Filterkorb mit 4,5 l lässt sich beidseitig öffnen und leicht ausspülen
Cons
- Bricht Reinigung immer wieder mit Fehlermeldung ab
- Verhakt sich an Leitern und Rollabdeckungen, teils nur mit Haken zu bergen
- Filterkorb mit 180 µm lässt Sand und Schwebstoffe durch
- Fernbedienung reagiert erst nach mehreren Versuchen, bei starker Sonne teils gar nicht
- Reinigungsergebnis und Poolkarte hängen stark vom Firmwarestand ab
