Verdict
Pros & cons
Der ECOVACS X12S OmniCyclone ist ein sehr gründlicher Saug- und Wischroboter mit beutelloser Station, der eingetrocknete Flecken per FocusJet meist im ersten Durchgang löst. Wenn du Haustiere oder lange Haare hast, sparst du dir dank keine Haarwickel an den Bürsten das Nacharbeiten. Der Haken: Schwellen nur bis 2,4 cm, außerdem leert sich der Akku auf großen Flächen schnell. In ebenen Wohnungen mit viel Hartboden spielt er seine Stärken voll aus.
Pros
- Nimmt auf Laminat in Tests 99,24 von 100 g Testmischung auf
- Keine Haarwickel an Haupt- und Seitenbürste, auch bei 1 m langem Kunsthaar
- FocusJet weicht eingetrocknete Ketchup- und Kaffeeflecken gezielt vor
- 27 cm breite Wischwalze reinigt Hartboden schneller als der Vorgänger
- Beutellose Station mit 75 °C Walzenwäsche und bis 70 °C beheizbarem Abwassertank
- Mechanische Kamerablende und Matter-Unterstützung
Cons
- Überwindet laut Hersteller nur Schwellen bis 2,4 cm
- Hoher Akkuverbrauch von 1,64 % pro m², ab 100 m² drohen Ladepausen
- Fuhr sich in einem Test auf Hochflor dreimal fest
- Erste Karte legt Räume falsch zusammen und braucht Nacharbeit
- Sieb der Waschschale und Abstreifer müssen von Hand gereinigt werden
Der Roborock Saros 20 Flow Complete ist ein starker Saug-Wisch-Roboter mit Wischwalze, der in Tests fast allen Schmutz vom Hartboden holte und kaum Eingriffe brauchte. Wenn du viel Hartboden, Tiere oder hohe Schwellen hast, bekommst du spürbar weniger Handarbeit im Alltag. Der Haken: Ecken und Fußleisten bleiben Nacharbeit, und Legosteine oder Tierkot übersieht er.
Pros
- Holte in Tests 99,65 von 100 g Testschmutz vom Laminat
- Keine Haarverwicklungen an der Bürste auf Hartboden und normalem Teppich
- Mit 8,98 cm Bauhöhe passt er unter Möbel ab rund 9 cm
- Klettert in Tests über einzelne Kanten von 4,5 bis 5,5 cm
- Walze wird im Roboter gewaschen, Waschschale der Station bleibt trocken
- Navigation meisterte Engstellen und Stuhlbeine ohne einen einzigen Eingriff
Cons
- Reste in Ecken und schmale Streifen an Fußleisten
- Übersieht Legosteine und kleinen Tierkot
- Auf Hochflor nur 76,19 g aufgenommen, Haare wickeln sich auf
- Staubbehälter mit 245 ml und Wassertank mit 67 ml knapp bemessen
- Beutelwechsel erst nach Herausheben beider Wassertanks
