Verdict
Pros & cons
Der Lefant M3 ist ein Saug-Wisch-Roboter mit LiDAR-Navigation und einer Station, die absaugt, die Mopps warm wäscht und trocknet. Damit nimmt er dir fast die ganze Pflege ab und reinigt aufgeräumte Hartböden zuverlässig. Der Haken: Ohne Kamera und Bumper übersieht er Kabel und flache Gegenstände, an angetrockneten Flecken scheitert er oft.
Pros
- Station saugt Staub ab, wäscht Mopps mit bis zu 45 °C und trocknet sie
- Zuverlässige LiDAR-Navigation mit bis zu 3 speicherbaren Etagenkarten
- Mopps heben sich auf Teppich automatisch um rund 9 mm an
- Kaum Haarverwicklungen dank Anti-Verhedderungs-Bürste
- Rund 120 m² am Stück, setzt nach dem Laden an der letzten Stelle fort
- Großzügiger Lieferumfang mit Ersatzmopps, Ersatzfilter und zweitem Staubbeutel
Cons
- Ohne Kamera und Bumper werden Kabel und Objekte unter etwa 4 cm übersehen
- Eingetrocknete Kakao- und Kaffeeflecken bleiben auch nach zwei Durchgängen sichtbar
- Kein Wassertank im Roboter, Mopps anfangs sehr nass und später eher trocken
- Absaugung laut, Sprachausgabe des Roboters nur auf Englisch
- Käufer melden verlorene Karten, Abpumpfehler der Station und WLAN-Aussetzer
Der Roborock Qrevo Edge 2 ist ein sehr gründlicher Sauger mit sicherer Navigation, der dank einfahrbarem Laserturm mit 7,98 cm unter flache Sofas passt. Hast du Teppiche, Tierhaare und niedrige Möbel, bekommst du ein ungewöhnlich vollständiges Paket der Mittelklasse. Der Haken: Eingetrocknete Flecken löst er meist nicht, und Schwellen über 2 cm bleiben ohne Kletterhilfe ein Hindernis.
Pros
- Nimmt auf Hartboden in Tests 96 bis über 99 % Schmutz auf
- Auf flachem Teppich noch 90 bis 95 % Schmutzaufnahme
- Keine Haarverwicklungen an Haupt- und Seitenbürste, auch bei 18 cm langen Haaren
- Mit eingefahrenem Laserturm nur 7,98 cm hoch
- Zuverlässige LiDAR-Navigation, Tester mussten wochenlang kaum eingreifen
- Moppwäsche mit 80 °C heißem Wasser und Warmlufttrocknung
Cons
- Rotierende Mopps mit 8 N lösen eingetrocknete Flecken meist nicht
- Schwellen nur bis 2 cm, keine Kletterhilfe
- Auf Hochflor bleibt rund ein Viertel des Schmutzes liegen
- Kleiner Staubbehälter mit 0,24 l füllt sich bei Fell schnell
- Kein Tank für Reinigungsmittel und kein Wasseranschluss
