+In addition to all [`vacuum` component attributes] (`battery_icon`, `cleaned_area`, `fan_speed`, `fan_speed_list`, `status`, `params`), the `xiaomi` platform introduces specific attributes to get information of the botvac.
+
+These are: `cleaning_time`, `do_not_disturb`, `main_brush_left`, `side_brush_left`, `filter_left`, `cleaning_count`, `total_cleaned_area` and `total_cleaning_time`.
+
+The following table shows the units of measurement for the single attributes.
