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 Shark PowerDetect UV Reveal ist eher Wischroboter als Allrounder: Eingetrocknete Flecken auf Hartboden schrubbt er gründlich und gezielt weg, die Station wäscht das Pad mit 85 °C. Auf Hochflor, bei Tierhaaren und frisch Verschüttetem schwächelt er, der Wasserverbrauch ist hoch. Weil die App nur eine Karte speichert, taugt er nur, wenn du auf einer Etage mit viel Hartboden wohnst.
Pros
- Schrubbt eingetrocknete Flecken wie Kaffee gezielt und gründlich nach
- Beutellose Station mit Moppwäsche bei 85 °C und Warmlufttrocknung
- Legt die Wischplatte beim reinen Saugen in der Station ab
- Zügige, genaue Kartierung per LiDAR-Laser und KI-Kamera
- Bis zu 180 min Akkulaufzeit, laut Vacuum Wars rund 195 m² pro Ladung
- Niedrige Folgekosten dank beutellosem 1,5-l-Staubbehälter
Cons
- Lässt auf Hochflor viel Feinschmutz liegen, bei netzwelt nur 17,5 von 30 g
- Haare wickeln sich trotz Anti-Verhedderungs-Bürste um die Walze
- Hoher Wasserverbrauch, Böden bleiben teils über 30 min feucht
- Nur eine Karte speicherbar, ungeeignet für mehrere Etagen
- Verheddert sich in Kabeln und scheitert an Schwellen ab 25 mm
