Verdict
Pros & cons
Der Dreame X50s Ultra ist ein flacher, kletterstarker Saugroboter mit Wischfunktion, dessen Station Absaugen, 100 °C heiße Moppwäsche und Trocknung übernimmt. Mit 7,95 cm Bauhöhe passt er unter viele Sofas und meistert Absätze im Altbau. Für große, verwinkelte Wohnungen mit Teppich und Hartboden ist er eine starke Wahl. Der Haken: Teppichkanten und eingetrocknete Flecken musst du gelegentlich von Hand nacharbeiten.
Pros
- Mit 7,95 cm Bauhöhe unter vielen Sofas und Betten unterwegs
- Klettert laut Hersteller über doppelte Stufen bis 8,8 cm
- Station wäscht Mopps mit bis zu 100 °C und trocknet mit Warmluft
- Doppelwalze nahm in Tests am Vorgänger Haare ohne Wickel auf
- Saugkraft laut Hersteller 35000 Pa, 75 Prozent mehr als der Vorgänger
- Bildverarbeitung der Kameras läuft lokal auf dem Roboter
Cons
- Teppichkanten und Ecken auf Teppich bleiben in Tests am Vorgänger schmutzig
- Eingetrocknete Flecken wie Ketchup lösen sich schwer
- Staubbehälter im Roboter mit 235 ml kleiner als beim Vorgänger
- Einweg-Staubbeutel verursachen Folgekosten und Müll
- Wasseranschluss nur gegen Aufpreis, Tanks von Hand füllen und leeren
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
