Eureka J15 Max Ultra
The extending brush and mop address a real class problem: the dust and film that fixed side brushes and round mop pads leave in corners, along baseboards and around table legs. The robot detects those geometries and extends into them on its own, with ScrubExtend holding 7 N of downward force while the mop is out. It reads shape rather than soil, so what it reaches is a function of the layout, not of how dirty a given spot is.

Position shows where the figure sits across the tracked category, not a quality judgment. Suction in Pascals has no standard test method, and the published figure is a peak-mode claim, so it is comparable only within a brand and generation.
