Verdict
Pros & cons
Der Dreame X40 Master ist ein sehr selbstständiger Oberklasse-Saugroboter, dessen flache Station direkt an Wasserleitung und Abfluss hängt. Auf Hartboden saugt er fast restlos sauber und reinigt Ecken gründlich, Tanks schleppen entfällt komplett. Hast du am Stellplatz einen Wasseranschluss und eine große Wohnung, lohnt er sich klar – der Haken sind Installationsaufwand und laute Absaugung.
Pros
- Auf Laminat 98,8 von 100 g Testschmutz in einer Fahrt aufgenommen
- Ausfahrbare Seitenbürste holte im Ecktest alle Maiskörner
- Station ohne Tanks, nur 28 cm hoch und passt unter Waschbecken
- Moppwäsche mit 70 °C heißem Wasser und Warmluft-Trocknung
- Großer Staubbeutel mit 4,2 l, laut Hersteller bis zu 100 Tage
- Mopps lassen sich für Teppiche in der Station ablegen
Cons
- Betrieb nur mit Festwasseranschluss und Abfluss möglich
- Station beim Absaugen mit 78 dB unangenehm laut
- Auf Teppich blieb knapp ein Fünftel des Testschmutzes liegen
- Lange Haare wickeln sich trotz Gummibürste um Bürstenteile
- Gelegentlich Streifen und Wasserflecken nach dem Wischen
Der Roborock Qrevo Curv 2 Pro ist ein starker Sauger mit schwachem Wischen. Mit 7,98 cm Bauhöhe kommt er unter niedrige Sofas, holt Tierhaare ohne Verheddern aus Teppichen und navigiert zuverlässig. Angetrocknete Flecken wischt er aber kaum weg, und kleine Hindernisse wie Kabel übersieht er oft. Wenn du Teppich, Tiere und flache Möbel hast, passt er gut. Für fleckige Hartböden ist ein Walzenmodell die bessere Wahl.
Pros
- Sehr hohe Saugleistung, in Tests 99 von 100 g auf Laminat
- Nur 7,98 cm hoch dank einfahrbarem Laserturm
- Haare verheddern sich kaum in der geteilten Hauptbürste
- Mopps bleiben beim Teppichsaugen in der Station, Teppich bleibt trocken
- Zuverlässige, systematische Navigation mit präziser Kartierung
- Gründliches Wischen an Fußleisten durch ausschwenkenden Mopp
Cons
- Angetrocknete Flecken wie Ketchup und Kaffee werden kaum entfernt
- Kleine Hindernisse wie Kabel, Legosteine und Schnürsenkel oft übersehen
- Kein Reinigungsmitteltank und kein fester Wasseranschluss
- Seitenbürste nicht anhebbar, verschmiert Flüssigkeiten
- Schwellen über 3 cm teils problematisch
