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 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
