Verdict
Pros & cons
Der Dreame Aqua20 Pro Ultra Roller X Complete ist ein umfassend ausgestatteter Saug- und Wischroboter mit Dampf und Kletterfahrwerk, das laut Hersteller Schwellen bis 5 cm nimmt. Er passt zu Hartboden mit eingetrockneten Küchenflecken und zu Altbauten mit hohen Schwellen. Der Haken: Die Dampfwirkung ist unabhängig noch unbelegt, und einige Funktionen kommen erst per Update. Brauchst du weder Dampf noch Kletterhilfe, reicht dir auch der Vorgänger.
Pros
- Dampf weicht eingetrocknete Flecken vor dem Wischen an
- Wischwalze fährt bis 8 cm aus und erreicht eingelassene Sockel
- Klettert laut Hersteller über Einzelstufen bis 5 cm und Doppelstufen bis 10 cm
- Station wäscht die Walze mit 100 °C und trocknet mit Warmluft
- Walze hebt sich über Teppich um 15 mm und wird abgedeckt
- Passt mit eingefahrenem Laserturm unter Möbel ab 98 mm
Cons
- Dampfwirkung bisher nicht unabhängig geprüft
- Raumdampf, Nachdampfen und adaptives Lernen kommen erst per Update
- Dampf und ausgefahrene Walze laufen nicht gleichzeitig
- Station braucht 42 x 44,1 cm Stellfläche und ist 50,2 cm hoch
- An den Düsen kommen nur 100 °C statt beworbener 180 °C an
Der Dreame X40 Ultra Complete ist ein Saug-Wischroboter, der dank ausfahrbarer Seitenbürste und ausfahrbarem Mopp Ecken und Stuhlbeine gründlich reinigt. Die Station wäscht die Pads heiß, trocknet sie und saugt den Behälter ab. Er passt zu Wohnungen mit viel Hartboden und Kurzflor. Der Haken steckt in der Software: Navigation und Hinderniserkennung patzen gelegentlich, und auf Hochflor bleibt feiner Schmutz liegen.
Pros
- Ausfahrbare Seitenbürste und Mopp reinigen Ecken, Fußleisten und Stuhlbeine gründlich
- Auf Hartboden bleibt nach einer Runde kaum Schmutz liegen
- Kurzflor: 91 % des Testschmutzes im ersten, 96 % im zweiten Durchgang
- Station wäscht Pads heiß, trocknet sie und saugt den Behälter ab
- Mopps lassen sich in der Station ablegen, Teppiche bleiben trocken
- Complete-Paket mit 14 Wischpads und 5 Staubbeuteln reicht etwa ein Jahr
Cons
- Navigation legt Denkpausen ein, Lokalisierung gerät teils durcheinander
- Hinderniserkennung meldet Phantomobjekte und übersieht teils Steckdosenleisten
- Lange Haare wickeln sich um die Gummiwalze, TriCut-Bürste kostet extra
- Auf mittel- und langflorigen Teppichen bleibt feiner Schmutz im Flor
- Station braucht rund 59 cm Höhe plus etwa 34 cm Platz darüber
