Verdict
Pros & cons
Der Dreame L40 Ultra A ist ein Saug-Wisch-Roboter für Tierhaushalte mit viel Hartboden. Die TriCut-Bürste schneidet aufgewickelte Haare durch, und die Station saugt den Staub in einen 3,2-l-Beutel ab. Der Haken: Die Mopps werden nur kalt gewaschen, und ohne Kamera erkennt er Kabel und Socken schlecht. Vor jedem Lauf räumst du darum kurz auf.
Pros
- TriCut-Bürste schneidet aufgewickelte Tierhaare direkt an der Walze durch
- Station saugt nach jeder Fahrt in einen 3,2-l-Staubbeutel ab
- Rechtes Pad fährt bis zu 4 cm zur Fußleiste aus
- Teppicherkennung hebt Pads um 10,5 mm und schaltet auf maximale Saugkraft
- Haustierbereich-Modus saugt Lieblingsplätze von Hund und Katze häufiger
- Bis zu 4 Etagenkarten mit Sperrzonen und Zeitplänen
Cons
- Keine Kamera: Kabel, Socken und Spielzeug werden schlecht erkannt
- Moppwäsche nur mit kaltem Wasser, keine Warmlufttrocknung
- Kein Wassertank im Roboter, Pads trocknen während der Fahrt aus
- Seitenbürste fährt nicht aus, in spitzen Ecken bleibt Staub liegen
- WLAN nur im 2,4-GHz-Band, Einrichtung der App mit Hürden
Der eufy Omni C20 ist ein flacher Saugroboter mit Station, der sehr gründlich wischt und mit 8,5 cm Bauhöhe unter niedrige Betten und Sofas passt. Er taugt für dich, wenn du viel Hartboden hast und vor allem wischen willst. Der Haken: Ohne Laserturm saugt er nur mittelmäßig, lässt Flächen aus und erkennt keine Kabel oder Kleinteile.
Pros
- Entfernt angetrockneten Ketchup, Kaffee und Schlamm in zwei Durchgängen vollständig
- Nur 8,5 cm hoch, passt unter Möbel ab knapp 9 cm Spalthöhe
- Station saugt ab, wäscht und trocknet die Pads automatisch
- Zuverlässige Teppicherkennung mit um 10 mm angehobenen Pads
- Kompakte Station mit 28,9 x 33,0 x 46,0 cm
- Bis zu 3 Etagenkarten, Steuerung per Alexa und Google Assistant
Cons
- Schwache Saugleistung, in Tests nur 90,9 % Schmutzaufnahme auf Teppich
- Ständiges Drehen zur Ortung verlängert die Reinigung und lässt Flächen aus
- Keine Erkennung von Kabeln, Socken und anderen Kleinteilen
- Lautes Trocknen der Pads mit Raumluft über standardmäßig 4 h
- Pad-Wäsche nur mit kaltem Wasser, kein fester Wasseranschluss
