Which extra capability matters?
K20+ Pro turns a compact cleaner into a moving base for compatible SwitchBot devices. Saros Z70 spends more of its hardware budget on manipulation and can physically relocate a narrow set of floor clutter.
For homes where socks, tissues and similar objects regularly block cleaning runs, the Z70’s arm addresses that problem directly. K20+ Pro costs less and offers a broader modular platform, while its physical cleaning work stays close to the established robot-vacuum category.
