Verdict
Pros & cons
Der Bosch Unlimited Serie 6 ist ein leichter Stielsauger mit Wechselakku, der auf Teppich gründlich saugt und mit 1,4 kg Handteil kaum ermüdet. Der Haken: nur 8 min im Turbo, ein 0,3-l-Behälter und rund 4 h Ladezeit. Für kleinere Wohnungen oder wenn du schon Power-for-All-Akkus hast, taugt er gut – für große Häuser zu knapp bemessen.
Pros
- Wechselakku aus dem 18-V-Power-for-All-System, auch für Bosch-Gartengeräte
- Handteil wiegt nur 1,4 kg, Komplettgerät 2,3 bis 2,4 kg
- Teppichdüse holt Tierhaare schon in der Normalstufe in einem Durchgang
- Düsengelenk nur 6 cm hoch, kommt weit unter Möbel
- Einrastender Hauptschalter ohne Dauerdrücken
- Filter ohne Waschen, Bürstenwalze werkzeuglos entnehmbar
Cons
- Turbo hält laut Hersteller nur bis zu 8 min pro Akku
- Staubbehälter mit 0,3 l muss in größeren Wohnungen mehrfach geleert werden
- Rund 4 h Ladezeit, Schnellladegerät nicht im Lieferumfang
- Saugrohr nicht ausziehbar, feste Länge von gut 120 cm
- Datenblatt nennt 85 dB, ein Test stuft ihn als laut ein
Der Dreame R20 SE-A ist ein schlichter Akku-Stielsauger, der Hartboden und Kurzflor gründlich reinigt; das blaue Düsenlicht zeigt dir dabei feinen Staub. Er passt zu Wohnungen bis etwa 80 m², die Stufen wählst du selbst. Der Haken: Turbo leert den Akku schnell, nach 10 bis 20 min ist Schluss, und auf Langflor saugt er sich fest.
Pros
- Nimmt Staub und Krümel auf Hartboden und Kurzflor meist in einem Zug auf
- Blaues Düsenlicht macht feinen Staub und Haare sichtbar
- Wechselakku ohne Werkzeug tauschbar, Ersatzakku von Dreame erhältlich
- Entleeren per Taste ohne Kontakt zum Schmutz
- Stabile Verarbeitung, Aufsätze rasten präzise ein
- In Eco und Med angenehm leise
Cons
- In Turbo ist der Akku nach 10 bis 20 min leer
- Saugt sich auf Langflor fest und schaltet ab
- Versprochene 90 min gelten nur in Eco mit kleiner Düse
- Kein Schmutzsensor, Stufe muss von Hand gewechselt werden
- Breite Bürste erreicht Ecken und Fußleisten nicht ganz
