Verdict
Pros & cons
Der BWT ES Nano ist ein schlichter Akku-Poolroboter für kleine Becken bis 10 m, der ohne Kabel Boden und Wände abfährt und am Ende am Rand parkt. Der wechselbare Akku reicht für genau einen Lauf von 150 min. Der Haken: Wie gründlich er Wasserlinie und Stufen reinigt, ist kaum belegt, und der 180-µm-Filter lässt Feinstaub durch.
Pros
- Kabellos: kein Schwimmkabel, kein Netzteil am Beckenrand
- Akku mit 4500 mAh wechselbar, verlängert die Lebensdauer
- Parkt nach dem Programm am Beckenrand, kein Haken nötig
- Salzwasser bis 4.000 ppm zulässig
- Modus auch ohne App direkt am Gerät wählbar
Cons
- Filter mit 180 µm hält Feinstaub und Pollen kaum zurück
- Eine Ladung reicht nur für einen Lauf, Laden dauert 5 bis 6 h
- Mit 7,5 kg trocken schwerer als die Kabelmodelle der Serie
- Keine Ladestation, Filter muss nach jedem Lauf gespült werden
- WLAN nur im 2,4-GHz-Netz
Der MOVA Diver R10 ist ein schlichter Akku-Roboter, der nur flache Beckenböden absaugt. Für kleine Aufstellpools mit Sand und wenig Laub reichen 3,4 kg Gewicht, Ein-Tasten-Bedienung und bis zu 120 min Laufzeit. Der Haken: Die Zufallsfahrt lässt Ecken aus, und zum Rand fährt er erst bei fast leerem Akku.
Pros
- Mit 3,4 kg einhändig aus dem Becken zu heben
- Kabellos mit bis zu 120 min Laufzeit pro Ladung
- Bedienung per einziger Taste, ohne App und Konto
- Zwei Motoren und zwei Bürsten lösen Sand und Belag am Boden
- Parkt bei fast leerem Akku selbst am Beckenrand
- Kompakte 30,2 x 27,4 x 18,1 cm, braucht kaum Lagerplatz
Cons
- Zufallsnavigation lässt Ecken und Kehle zur Wand oft aus
- Vorzeitiges Zurückholen an den Rand nicht möglich, sonst nur per Haken
- Filterkorb mit 1,7 l unter Bäumen schnell voll
- Kein Zeitplan, jeder Lauf muss von Hand gestartet werden
- Nachladen dauert 210 min
