Verdict
Pros & cons
Der BWT FSA 1800 ist ein Kabelroboter für Boden, Wand und Wasserlinie, der mit rund 5,8 kg auffallend leicht zu bergen ist. Er fährt per Gyroskop in Bahnen und hat ein eigenes Programm für die Wasserlinie. Das passt gut zu Becken bis etwa 8 m mit Laub. Der Haken: Der Filter mit 100 µm lässt feinen Staub durch, und unabhängige Reinigungsergebnisse fehlen bisher.
Pros
- Mit rund 5,8 kg etwa halb so schwer wie der B200
- Schnellablass lässt das Wasser beim Herausheben zügig ab
- Eigenes Programm für die Wasserlinie
- Fährt per Gyroskop in parallelen Bahnen statt zufällig
- Grober Filter setzt sich bei viel Laub nicht so schnell zu
- Per App starten, stoppen und gezielt an Problemstellen lenken
Cons
- Filter mit 100 µm lässt feinen Staub und Pollen teilweise durch
- Kabel mit 16 m wird bei 10 m langen Becken knapp
- Ecken und Übergang Boden–Wand brauchen voraussichtlich Nacharbeit mit der Bürste
Der Dreame Z1 ist ein kabelloser Poolroboter für Boden, Wände und Wasserlinie mit kräftiger Saugleistung für groben Schmutz. Im rechteckigen Becken mit fester Treppe ist der Boden nach einem Lauf sauber. In Ecken bleibt Schmutz liegen, unter Einhängeleitern verkeilt er sich, und feiner Staub geht durch den Filter. Musst du dich nie um ihn kümmern wollen, ist er für dich die falsche Wahl.
Pros
- Saugt Laub, Sand und groben Dreck zuverlässig in den Korb
- Reinigt Boden, Wände und Wasserlinie ohne Schwimmkabel
- Akku hält knapp 3 h bei Boden, Wand und Wasserlinie
- Parkt nach dem Lauf an der Wasserlinie zum Herausheben
- Filterkorb mit 4,5 l in unter zwei Minuten ausgespült
- App mit Wochenzeitplan, Zonenreinigung und Laufprotokoll
Cons
- Lässt in Ecken und an Wänden regelmäßig Schmutzstreifen liegen
- Verkeilt sich unter Einhängeleitern und bricht den Lauf ab
- Filter mit 180 µm lässt Feinschmutz zurück ins Wasser
- Teils Ausfälle nach Wochen und ein langsamer Kundendienst
- Volle Ladung dauert 4 bis 6 h, keine Ladestation
