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 MOVA E40 Ultra ist ein Saugroboter mit Komplettstation, der auf Hartboden fast restlos saugt und dir dank Absaugung, Moppwäsche und Warmlufttrocknung viel Handarbeit abnimmt. Der Haken: Er wischt angetrocknete Flecken nur schwach und übersieht ohne Kamera dünne Kabel und Tierkot. Damit passt er am besten in aufgeräumte Wohnungen mit viel Hartboden.
Pros
- Gründliche Saugleistung auf Hartboden, im Test 98,18 g von 100 g aufgenommen
- Station saugt ab, wäscht Mopps und trocknet sie mit Warmluft
- Ausfahrbarer Mopp wischt bis an Kanten und unter Türen
- Seitenbürste mit Gummistreifen verheddert kaum Haare
- Mopps heben sich auf Teppich um 10,5 mm automatisch an
- 3 Jahre Garantie laut Datenblatt
Cons
- Schwache Fleckentfernung bei angetrocknetem Kaffee, Ketchup oder Saft
- Hinderniserkennung ohne Kamera übersieht Kabel, Stuhlbeine und Tierkot
- Seitenbürste nicht ausfahrbar, Ecken bleiben schmutzig
- Lange Haare wickeln sich um die Hauptbürste
- Kaum Ersatzteile im Lieferumfang, Moppwäsche nur mit kaltem Wasser
