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 L50 Ultra AE ist ein solider Sauger, kein Allrounder: Auf Hartboden holt er in einer Überfahrt fast allen Schmutz, die ausfahrbare Seitenbürste reinigt Ecken gründlich, und die Station wäscht die Mopps mit 100 °C. Der Haken: Ohne KI-Kamera übersieht er Kabel, Socken und Tierkot, auf Hochflor saugt er schwach, eingetrocknete Flecken verschmiert er. Für aufgeräumte Wohnungen mit viel Hartboden halten wir ihn für eine vernünftige Wahl.
Pros
- Saugt Hartboden in einer Überfahrt fast restlos, im Test 96,68 % auf Laminat
- Ausfahrbare Seitenbürste holt Schmutz zuverlässig aus Zimmerecken
- Station mit 100 °C Moppwäsche, Warmlufttrocknung und Reinigungsmitteldosierung
- Sparsamer Akkuverbrauch, 85 m² mit einer Ladung
- Im Saugbetrieb vergleichsweise leise, 60,7 dB im Standardmodus
Cons
- Hinderniserkennung ohne KI übersieht dünne Kabel, Socken und Tierkot
- Schwach auf Hochflor, im Test nur 36,92 % Schmutzaufnahme
- Eingetrocknete Flecken werden eher verschmiert als gelöst
- Kleiner Staubbehälter mit 0,25 l und kein HEPA-Filter
- Mit 10,38 cm Bauhöhe zu hoch für viele flache Möbel
