Verdict
Pros & cons
Der ECOVACS Deebot N20 ist ein gründlicher Sauger für Hartboden mit Laser-Navigation und einer Hauptbürste, an der sich keine Haare aufwickeln. Für Tierhalter in aufgeräumten Wohnungen taugt er gut. Der Haken: Kabel und Socken erkennt er nicht, das Wischpad zieht er nur nach und hebt es auf Teppich nicht an. Den kleinen Staubbehälter mit 0,4 l musst du oft von Hand leeren.
Pros
- Sammelt auf Laminat in Tests fast allen Schmutz ein
- Keine Haarwicklungen: 18 cm lange Haare verhedderten sich im Test nicht
- Holte im Test 96 % der Tierhaare aus Teppich
- LiDAR-Karte nach etwa 5 min, ordentliche Bahnen, 3 Etagenkarten
- 190 min Laufzeit im Standardmodus, setzt Reinigung nach dem Laden fort
- Übersichtliche App mit Raumeinstellungen, No-Go-Zonen und Zeitplänen
Cons
- Keine Kamera-Hinderniserkennung, Kabel und Socken bleiben unerkannt
- Wischpad hebt sich auf Teppich nicht an und muss abgenommen werden
- Gezogenes Pad scheitert an angetrockneten Flecken
- Staubbehälter mit 0,4 l füllt sich schnell
- Lange Ladezeit von 390 min, schwach in Ecken
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
