Verdict
Pros & cons
Der Dreame X50 Ultra Complete ist ein gründlicher Saug- und Wischroboter, der Hindernisse sicher umfährt und dank Kletterbeinen Schwellen bis 6 cm nimmt. Er passt zu Wohnungen mit hohen Übergängen, Haustieren und viel Hartboden. Der Haken: Er arbeitet langsam, der Akku reicht für rund 80 m², und Kartenfehler und frühe Defekte treten wiederholt auf.
Pros
- Klettert über doppelte Schwellen bis 6 cm, einzelne Kanten bis 4,2 cm
- Wischt eingetrocknete Flecken ohne höchste Wasserstufe weg
- Hinterlässt auf Hartboden von 10 g Sand und Haferflocken nichts
- Doppelwalze bleibt auch nach einem Monat frei von langen Haaren
- Umfährt Socken, Kabel und Haustiere meist ohne Berührung
- Station wäscht Pads mit 80 °C heißem Wasser und trocknet sie
Cons
- Akku reicht bei Standardeinstellungen nur für rund 80 m²
- Langsam: über anderthalb Stunden für 70 m²
- Karte und Navigation zeitweise fehlerhaft, Defekte teils in den ersten Monaten
- Schmutz bleibt an Teppichkanten und in Ecken liegen
- Hochflor wird nur mühsam befahren und braucht zweite Durchgänge
Der Roborock Saros 20 ist ein sehr gründlicher Sauger mit nur 7,98 cm Bauhöhe, der unter flache Sofas fährt und Schwellen bis 4,5 cm meistert. Auf Teppich, Hochflor und Hartboden überzeugt er, die Station nimmt dir mit Heißwasserwäsche und Absaugung viel Arbeit ab. Der Haken: Beim Wischen nur Mittelmaß, angetrocknete Flecken brauchen mehrere Durchgänge und Flüssigkeiten verschmiert er eher.
Pros
- Starke Saugleistung auf Hochflor, flachem Teppich und Hartboden
- Nur 7,98 cm hoch, reinigt unter flachen Sofas und Betten
- Kletterfahrwerk überwindet einzelne Türschwellen bis 4,5 cm
- Geteilte Hauptbürste verhindert meist Verwicklungen mit Tierhaaren
- Station mit heißer Moppwäsche, Warmlufttrocknung und Absaugung
- Mopps werden vor dem Saugen in der Station abgelegt, Teppiche bleiben trocken
Cons
- Angetrocknete Flecken brauchen oft zwei bis drei Wischgänge
- Verschüttete Flüssigkeiten werden eher verschmiert als aufgenommen
- Seitenbürste nicht anhebbar, schleudert groben Schmutz wie Katzenstreu weg
- Übersieht kleine Gegenstände wie Legosteine, Stifte und Schlüssel
- Reinigungsmittel meist nicht im Lieferumfang
