Verdict
Pros & cons
Der Dreame X40 Master ist ein sehr selbstständiger Oberklasse-Saugroboter, dessen flache Station direkt an Wasserleitung und Abfluss hängt. Auf Hartboden saugt er fast restlos sauber und reinigt Ecken gründlich, Tanks schleppen entfällt komplett. Hast du am Stellplatz einen Wasseranschluss und eine große Wohnung, lohnt er sich klar – der Haken sind Installationsaufwand und laute Absaugung.
Pros
- Auf Laminat 98,8 von 100 g Testschmutz in einer Fahrt aufgenommen
- Ausfahrbare Seitenbürste holte im Ecktest alle Maiskörner
- Station ohne Tanks, nur 28 cm hoch und passt unter Waschbecken
- Moppwäsche mit 70 °C heißem Wasser und Warmluft-Trocknung
- Großer Staubbeutel mit 4,2 l, laut Hersteller bis zu 100 Tage
- Mopps lassen sich für Teppiche in der Station ablegen
Cons
- Betrieb nur mit Festwasseranschluss und Abfluss möglich
- Station beim Absaugen mit 78 dB unangenehm laut
- Auf Teppich blieb knapp ein Fünftel des Testschmutzes liegen
- Lange Haare wickeln sich trotz Gummibürste um Bürstenteile
- Gelegentlich Streifen und Wasserflecken nach dem Wischen
Der eufy HydroJet C28 ist ein Saug-Wisch-Roboter mit Walze und Komplettstation, der Tierhaare ohne jede Verwicklung aufnimmt und frische Flecken mit wenig Restnässe entfernt. Für Hartböden mit Haustier ist er ein starkes Paket. Der Haken: Kabel und Socken übersieht er oft, er rempelt Möbel an, schafft nur 2 cm Schwellen und die Station wird beim Absaugen knapp 75 dB laut. Vor jedem Lauf solltest du also kurz aufräumen.
Pros
- Keine Haarumwicklung im Test mit rund 18 cm langen Strähnen
- Starke Hartbodenreinigung mit 93 von 100 g aufgenommenem Testschmutz
- Wischwalze hinterlässt nur 0,25 g Restnässe und entfernt frische Flecken gründlich
- Eckige Front reinigt Ecken und Fußleisten gründlicher als runde Modelle
- Station saugt ab, wäscht die Walze, trocknet mit Warmluft und füllt nach
- Schnelle, genaue LiDAR-Kartierung in knapp 5 min
Cons
- Linienlaser ohne Kamera übersieht Kabel, Socken und flache Gegenstände oft
- Ruppiger Fahrstil, rammt Tischbeine und Sockelleisten
- Absaugen in der Station mit knapp 75 dB laut
- Schwellen nur bis 2 cm, Bauhöhe von rund 11 cm
- Eingetrocknete Flecken und ein 3 cm breiter Randstreifen bleiben ungewischt
