Abstract
A dust collection box and a robot vacuum cleaner are disclosed. The dust collection box includes a box body, a first lid detachably arranged to the box body, a filter, and a filter missing-alert device arranged to the first lid. The filter missing-alert device includes a movable member. When the filter is not mounted into the box body and the first lid is arranged to be closed on to the box body, the movable member interferes with the box body, such that the box body cannot be closed with the first lid. When the filter is mounted into the box body and the first lid is arranged to the box body, the filter missing-alert device interferes with the filter to eliminate the interference between the movable member and the box body, such that the box body can be closed with the first lid.
