Verdict
Pros & cons
Der Dreame L40s Pro Ultra ist ein Saug-Wisch-Roboter mit Komplettstation, der auf Hartboden und Kurzflor fast restlos sauber macht. Seine Doppelwalze wickelt kaum Haare auf, Tierkot umfährt er zuverlässig – damit ist er eine starke Wahl für Tierhalter. Der Haken: Auf Hochflor bleibt viel Schmutz liegen, und an Schwellen ab 2 cm brauchst du die App als Hilfe.
Pros
- Holte in Tests 98,72 von 100 g Schmutz vom Laminat
- Doppelwalze wickelt auch lange Tierhaare kaum auf
- Entfernt Flecken samt Kaffee schlierenfrei, ausfahrbares Pad reinigt Kanten
- Station saugt ab, wäscht die Pads warm und trocknet sie
- Umfuhr in Tests beide Hundehaufen vollständig
- Ausfahrbare Seitenbürste holt Schmutz aus Ecken
Cons
- Auf Hochflor nur rund 23 von 100 g Schmutz aufgenommen
- Navigation auf Langflor ohne erkennbares Muster
- Scheiterte ohne App-Hilfe schon an 2 cm hohen Schwellen
- Station braucht rund 34 x 46 x 59 cm Stellfläche
- Nur 1 Jahr Garantie
Der Roborock Qrevo Curv löst zwei konkrete Alltagsprobleme: Er klettert über Schwellen bis 3 cm und verheddert kaum Haare. Dazu wäscht die Station die Mopps mit 75 °C und trocknet sie mit Warmluft. Der Haken: Er übersieht Kabel und Kleinteile, und mit 10,3 cm passt er nicht unter jedes Sofa. Für ebene Hartböden zahlst du für Reserven, die du kaum nutzt.
Pros
- Klettert über Schwellen bis 3 cm, gestuft bis 4 cm
- Geteilte Hauptbürste blieb in mehreren Tests frei von verhedderten Haaren
- Station wäscht Mopps mit 75 °C und trocknet sie mit Warmluft
- Auf Teppich im Test 94 Prozent Schmutzaufnahme
- Ausfahrbarer Arm wischt bündig an Fußleisten entlang
- Roboter fährt ganz in die kompakte Station hinein
Cons
- Übersieht dünne Kabel und Gegenstände unter 5 cm Breite
- Kein Wasseranschluss und kein Fach für Reinigungsmittel
- Mit 10,3 cm Bauhöhe zu hoch für niedrige Sofas
- Mageres Zubehör, außer einem Ersatzbeutel kaum etwas im Karton
- Hohe Saugkraft bringt auf Hartboden kaum Vorteil
