Verdict
Pros & cons
Der Dreame D20 Air Plus ist ein kräftiger Sauger mit Absaugstation und Laser-Navigation für aufgeräumte Wohnungen bis etwa 50 m². Die Station leert ihn in einen 4-l-Beutel, sodass du dich kaum um ihn kümmern musst. Der Haken: Das mitgezogene Tuch wischt nur oberflächlich, Hindernisse bemerkt er erst über die Stoßleiste, und mit bis zu 76 dB ist er zu laut für die Nacht.
Pros
- Hohe Saugleistung, nimmt in Tests Steinchen, Sand und Kiefernnadeln auf
- Kompakte Absaugstation mit 4-l-Beutel, laut Hersteller bis zu 120 Tage
- LiDAR-Navigation mit systematischen Bahnen, auch bei Dunkelheit zuverlässig
- Bis zu 4 Etagenkarten mit Raumauswahl, Sperrzonen und Zeitplänen
- Teppicherkennung mit automatischem Saugkraft-Boost
- Station mit 29,3 x 20,1 x 26,65 cm passt auch in schmale Flure
Cons
- Mitgezogenes Wischtuch löst kaum Flecken und reinigt sich nicht selbst
- Keine Kamera, schiebt leichte Behälter und kleine Matten vor sich her
- Bis 76 dB auf Max-Stufe, für Reinigungen in der Nacht zu laut
- Kleiner Akku mit 3.200 mAh, in Tests rund 43 m² in 57 min
- Wischpad lässt sich nicht anheben, Teppiche müssen gesperrt werden
Der eufy HydroJet E28 ist ein Saug- und Wischroboter mit abnehmbarem Nasssauger für Polster und Autositze. Auf Hartboden wischt er stark und gründlich, auf Hochflor blieb in Tests aber mindestens ein Drittel des Schmutzes liegen. Er lohnt sich für dich nur bei viel Fliesen oder Laminat und hellen Polstern. Der Nasssauger braucht nach 30 min 3,5 h Abkühlpause.
Pros
- Wischwalze nimmt frische und verschüttete Flüssigkeiten gründlich auf
- Abnehmbarer Nasssauger entfernt frische Flecken auf Polstern und Autositzen
- Weicht in einem Test 23 von 24 Hindernissen aus, auch Haustierkot
- Station saugt ab, wäscht die Walze und trocknet sie mit Warmluft
- Teppicherkennung schaltet auf Kurzflor zuverlässig den Saugboost zu
- Steuerung per Alexa, Google Assistant, Siri und Matter
Cons
- Auf Hochflor blieb in Tests mindestens ein Drittel des Schmutzes liegen
- Sehr lange Haare wickeln sich zu dichten Knäueln hinter der Bürste
- Mit 11,1 cm Bauhöhe passt er nicht unter jedes Sofa
- Station beim Absaugen sehr laut, Trocknung stundenlang hörbar
- Nasssauger nach 30 min Einsatz 3,5 h in der Abkühlpause
