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 Dyson R2 Nurovi Wash+Dry ist ein gründlicher Sauger für Hartboden, der nebenbei feucht durchwischt und seine Pads mit 75 °C heißem Wasser wäscht. Der Haken: Staub bleibt oft im Roboter, du leerst den 0,15-l-Behälter nach größeren Fahrten selbst. Bei eingetrockneten Flecken, langen Haaren und Hochflor stößt er an Grenzen.
Pros
- Nimmt auf Hartboden rund 90 % des Staubs im ersten Durchgang auf
- Wäscht Pads mit 75 °C heißem Wasser und trocknet sie mit Warmluft
- Beutellose Station mit 2,6 l erspart den Kauf von Staubbeuteln
- Ausfahrende Seitenbürste holt Staub und Haare entlang der Fußleisten
- Station nur 41,5 cm tief, passt auch in schmale Flure
- Umfährt kleine Hindernisse wie Glas, Batterien und Fernbedienung
Cons
- Staub bleibt im Roboterbehälter hängen, Station saugt ihn nicht vollständig ab
- Lange Haare wickeln sich trotz Anti-Tangle-Versprechen um die Walze
- Eingetrocknete Flecken bleiben liegen, Dreieckspads bringen in Ecken keinen Vorteil
- 0,1 l Wassertank zwingt beim Wischen zu häufigen Stationsfahrten
- Erkennt flach liegende Kabel nicht, sie verfangen sich in den Pads
