Verdict
Pros & cons
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
Der Dyson Spot+Scrub AI ist ein Wischspezialist für glatte Böden: Seine selbstreinigende Walze hinterlässt auf Fliesen und versiegeltem Parkett saubere, schlierenfreie Ergebnisse. Für offene Wohnungen mit viel Hartboden taugt er gut. Der Haken: schwache Ecken, nur 2 cm Kletterhöhe, Probleme mit dünnen Teppichen und Haare an der Bürste. Hast du Altbau, Teppich oder Tiere, greifst du besser zur Konkurrenz.
Pros
- Sehr saubere Wischergebnisse auf Fliesen und versiegeltem Parkett
- Walze wird während der Fahrt abgestreift und neu befeuchtet
- Station wäscht die Walze mit 60 °C und trocknet mit Warmluft
- Beutellose Station mit 3 l Staubvolumen ohne Folgekosten für Beutel
- Kamerabilder werden laut Hersteller lokal verarbeitet, nicht in der Cloud
- Auf Hartboden 90 bis 98 % Schmutzaufnahme in mehreren Tests
Cons
- Schwache Eckenreinigung durch starre Seitenbürsten
- Nur rund 2 cm Kletterhöhe bei 11 cm Bauhöhe
- Lange Haare wickeln sich um die Hauptbürste
- Klappt Kanten dünner Teppiche um oder schiebt sie vor sich her
- Fleckenerkennung versagt bei verschütteten Flüssigkeiten und eingetrockneten Soßen
