Verdict
Pros & cons
Der Dreame D20 ist ein kräftiger Sauger für Tierhaushalte mit Laser-Navigation und Doppelwalze, die Haarknäuel weitgehend verhindert. Die 285 min Laufzeit und der 0,7 l große Behälter reichen auch für große Wohnungen. Der Haken: keine Absaugstation, keine Hinderniserkennung – du leerst von Hand und räumst vorher auf, und das mitgezogene Tuch frischt nur auf statt zu wischen.
Pros
- Doppelwalze mit Anti-Haar-Technik aus teureren Dreame-Modellen
- Hohe Saugkraft von 13000 Pa laut Hersteller
- Großer Staubbehälter mit 0,7 l für seltenes Leeren
- Laser-Navigation mit Raumkarten, Sperrzonen und Zeitplänen
- Lange Laufzeit bis 285 min, auch für über 100 m²
- Sprachsteuerung per Alexa, Siri oder Google Assistant
Cons
- Nur Ladestation, der Staubbehälter wird von Hand geleert
- Passives Wischtuch entfernt keine eingetrockneten Flecken
- Wischpad hebt sich über Teppich nicht an
- Keine Hinderniserkennung, Kabel und Socken werden eingesaugt
- Lange Ladezeit von 360 min, Seitenbürste fährt nicht aus
Der iRobot Roomba Max 875 ist ein Saug-Wisch-Roboter mit Heißwasser-Station, der auf Teppich kräftig saugt und Schwellen bis 3,5 cm nimmt. Er passt zu dir, wenn du vor allem saugen lässt und Flecken gelegentlich selbst nachwischst. Der Haken: Eingetrocknete Flecken bleiben oft stehen, an Kanten bleiben Streifen, und die App arbeitet noch unzuverlässig. Auf alten Holzdielen oder empfindlichem PVC ist er keine sichere Wahl.
Pros
- Saugt Vorleger und Kurzflor gründlich dank abgedichteter Saugschürze
- Überwindet Schwellen bis 3,5 cm, auch steile Badschwellen ohne Rampe
- Station wäscht die Wischrolle mit 80 °C und trocknet sie warm
- Passt mit 9,98 cm Bauhöhe unter flache Couchtische
- Lange Haare wickeln sich dank Haarschneider kaum um die Bürste
- Im Standardmodus auf Hartboden leise genug für Gespräche daneben
Cons
- App verschachtelt, ohne frei aufziehbare Zonen und ohne Fahrtrichtung pro Raum
- Eingetrocknete Flecken bleiben oft auch nach mehreren Wischgängen sichtbar
- Lässt an Wänden 0,5 bis über 2 cm ungereinigt
- Erkennt Kabel nicht verlässlich, meidet Flächen zwischen Stuhlbeinen
- Walze hinterlässt auf alten Holzdielen zu viel Feuchtigkeit
