Verdict
Pros & cons
Der roborock Qrevo Curv 2 Flow ist ein solider Allrounder für Hartböden mit präziser LiDAR-Navigation und einer Station, die die Wischwalze heiß wäscht und warm trocknet. Frische Flüssigkeiten nimmt die Walze zuverlässig in einem Durchgang auf, bei eingetrockneten Flecken braucht sie oft mehrere Anläufe. Der Haken: Mit 11,9 cm Bauhöhe passt er unter viele Sofas nicht – miss vor dem Kauf deine Möbel nach.
Pros
- Saugt Hartboden fast restlos sauber, in Tests 99,18 von 100 g auf Laminat
- Walze nimmt frische Flüssigkeiten wie Kaffee oder Milch in einem Durchgang auf
- Präzise LiDAR-Karte, Räume in Tests auf Anhieb korrekt getrennt
- Station wäscht die Walze laut Hersteller mit 75 °C und trocknet warm
- Haare wickeln sich an der geteilten Hauptbürste kaum auf
- Teppiche bleiben dank 15 mm Walzenanhebung und Abdeckung trocken
Cons
- 11,9 cm Bauhöhe sperrt flache Sofas und Schränke aus
- Schwach bei eingetrockneten Flecken, oft mehrere Durchgänge nötig
- Seitenbürsten nicht ausfahrbar, in Ecken bleibt Schmutz liegen
- Schwellen nur bis 2 cm, fährt sich auf Hochflor fest
- Kein reiner Wischmodus außerhalb der 4-m²-Zone, kein Reinigungsmitteltank
Der Roborock S8 MaxV Ultra ist ein Saugroboter mit Komfortstation, der auf Hartboden nahezu allen Schmutz aufnimmt und Ecken und Kanten vorbildlich reinigt. Er taugt für dich, wenn du viel Hartboden, Haustiere und wenig Lust auf Wartung hast. Der Haken: Das vibrierende Wischpad scheitert an eingetrockneten Flecken, außerdem sind 270 ml Staubbehälter und 10,3 cm Bauhöhe knapp bemessen.
Pros
- Nimmt auf Fliesen und Laminat 96 bis 100 % des Testschmutzes auf
- Ausfahrbare Seitenbürste holte im Eckentest 5 von 5 Maiskörnern heraus
- Station wäscht das Pad mit 60 °C und trocknet es mit Warmluft
- Hebt Pad und Kantenmopp auf Teppich um 20 mm an
- Umfährt Kabel, Möbel und Steckerleisten mit Kamera zuverlässig
- Gegenläufige Gummiwalzen ohne Werkzeug entnehmbar und schnell von Haaren befreit
Cons
- Vibrierendes Pad entfernt eingetrocknete Flecken erst nach mehreren Durchgängen oder gar nicht
- Staubbehälter mit 270 ml kleiner als beim Vorgänger mit 350 ml
- Mit 10,3 cm Bauhöhe passt er nicht unter jedes Sofa
- Erste Kartierung in einem Test langsam und mit falscher Raumaufteilung
- Einweg-Staubbeutel verursachen laufende Folgekosten
