Minutes of runtime, and the three surfaces they are spent on · review
A three-zone robot that brushes the waterline for eight seconds at a time, publishes 25 700 LPH of suction and a 5-litre basket, and parks itself at the waterline for ten minutes so it can be lifted out without fishing.
The bottom line The waterline is the reason. Three zones, a published dwell time on the mark that actually shows, a 150 µm filter finer than the shelf standard and a parking routine that thinks about the person lifting it out. The fine filter being an extra purchase is the catch, and at this price the 3 µm element should have been in the box rather than in the catalogue.
A cordless robot covering floor, walls and waterline, plus flat areas from 30 cm of water depth. Suction is stated at 25 700 LPH, from a construction the maker calls HydroBalance. The battery is 7 800 mAh, giving up to five hours of floor cleaning and a stated coverage of 300 m² per charge.
The basket holds 5 litres — stated as up to 650 leaves — behind a 150 µm filter, with a 3 µm fine filter available separately. Obstacle detection is by a front ultrasonic sensor the maker names SonicSense. Control is by app over Wi-Fi or Bluetooth. Two front roller brushes provide traction.
Brushes the waterline for 8 seconds. On a shelf where waterline cleaning is usually a bullet point, a published dwell time is a different kind of claim — it describes a behaviour that can be observed rather than a capability that cannot.
The waterline is also the band that shows. Oils and dust collect there against the liner, it is the first part of a pool to look neglected, and it is the zone most of this family does not touch at all.
150 µm is finer than the 180 µm the rest of this family uses as standard. The 3 µm ultra-fine element is where the dust and algae claims come from, and it is sold separately.
That is a second purchase before the machine does what the listing describes, and this page adds it back rather than leaving it in a footnote.
Charge time, on a battery rated for five hours of work. Weight, on a machine that comes out of the water by hand. And whether that 7 800 mAh pack can be replaced — the question that decides whether this is a ten-year purchase or a four-year one, and which nobody in this family answers.

That the robot holds position at the waterline and works it rather than passing along it. Eight seconds is the maker’s published figure, and it is unusually specific for this shelf — most waterline claims are a capability with no duration attached.
It is finer, and it is the finest standard filter in this family. Whether that matters depends on what falls in the pool: for leaves and sand the difference is nothing, for fine dust and algae it is the whole point. The 3 µm option exists for the second case and is sold separately.
Because a cordless robot at the bottom of a pool has to come out somehow, and the usual answer is a hook and an arm in the water. Parking at the waterline and holding for ten minutes is the most explicit retrieval arrangement published in this family.
A pool with a visible waterline mark and enough surface to justify the runtime

Floor, wall, waterline; 270 min eco; 11 sensors; 3 µm included
A three-zone robot with eleven sensors and a published path algorithm, a dual-layer filter whose 3 µm element is included rather than optional, and five cleaning modes with over-the-air updates.
Best for: A shaped pool where systematic coverage is worth more than raw suction
Floor, wall, waterline; 2 h; 18 927 LPH; IP68 to 3 m
A three-zone tracked robot that publishes what it climbs in degrees and centimetres — 30° slopes and 3 cm obstacles — with IP68 to a stated three metres and a 4-litre basket.
Best for: A pool with steps, a drain cover or a change of level that defeats a simpler machine
Floor, 90 min, 180 µm + 40 PPI foam, 3 kg
A floor robot with a two-stage filter — a 180 µm mesh backed by a 40 PPI foam — a transparent housing so the basket can be read without opening it, and a published weight of 3 kg.
Best for: A pool under trees, where the second filter stage and the visible basket both earn their place
