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 Narwal Freo 20 ist ein Wischroboter, der auch saugt: Seine Walze nimmt Kaffee, Tee und Fußspuren streifenfrei in einem Durchgang auf, und die Station wäscht sie mit bis zu 100 °C. Für Wohnungen mit viel Hartboden auf einer Ebene taugt er sehr gut. Der Haken: Feinstaub und Sand bleiben im Teppich, Ecken werden nicht ganz sauber, und an Stufen arbeitet er unsicher.
Pros
- Wischwalze entfernt Kaffee und Tee in einer Überfahrt ohne Schlieren
- Station wäscht die Walze mit bis zu 100 °C und trocknet mit Warmluft
- Auf Hartboden blieben von 50 g Testschmutz nur 6 g liegen
- Haare bis 30 cm ohne Verheddern an der Seitenbürste aufgenommen
- Mit 9,5 cm Bauhöhe passt er unter Betten und niedrige Sideboards
- Wich 23 von 24 Hindernissen aus, etwa Kabel, Schuhe und Socken
Cons
- Auf Teppich bleiben Feinstaub und Sand liegen, bei Sand nur 70 % Aufnahme
- Stürzte in einem Test trotz Absturzsensoren eine Stufe hinunter
- Starre Seitenbürste lässt Krümel in Ecken liegen und schleudert Katzenstreu
- Teppiche nach Kartierung standardmäßig vom Saugen ausgeschlossen, versteckt in der App
- Kleinteile wie Stifte und Bausteine erkennt die Kamera oft nicht
