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 Dreame L40 Ultra AE ist ein Saug- und Wischroboter für Wohnungen mit viel Hartboden und Haaren. Auf Laminat sammelt er in einer Fahrt gut 97 von 100 g Schmutz ein, die Station wäscht die Mopps mit 75 °C und trocknet sie warm. Der Haken: Die starre Seitenbürste lässt Zimmerecken voller Schmutz zurück, Langflor fährt er gar nicht an, und einzelne Geräte fallen früh aus.
Pros
- Holt in einer Fahrt 97,44 von 100 g Schmutz vom Laminat
- TriCut-Bürste nimmt lange Haare ohne Aufwickeln auf, liegt bei
- Station wäscht Mopps mit 75 °C und trocknet sie warm
- Erkennt Hundekot zuverlässig, umfährt 12 von 16 Objekten
- Mit 9,7 cm Bauhöhe kommt er unter viele Möbel
- Überwindet Türschwellen bis 2,2 cm ohne Hilfe
Cons
- Starre Seitenbürste holt kein einziges Maiskorn aus Zimmerecken
- Auf Teppich bleibt nach einer Fahrt ein Viertel des Schmutzes
- Mopps heben nur 10,5 mm, Langflor wird ausgelassen
- Einzelne Geräte fallen nach Wochen bis acht Monaten aus
- Übersieht dünne Kabel, Stifte und sehr flache Gegenstände
