Abstract: A child safe mop bucket assembly that prevents a child from accessing the contents of the bucket yet enables a mop to extend out of the bucket. The bucket assembly includes a fluid impermeable container having an open end and a lid element sized to cover that open end. The lid element contains an opening that enables a mop handle to extend out through the lid element if a mop is left within the container. The lid element also includes at least one locking pawl that engages the container when the lid element is closed over the open end of the container. The locking pawl is configured to be easily opened by an adult, yet cannot be opened by a small child. As a result, the lid element prevents a small child from accessing the contents of the bucket assembly even when a mop is left within the bucket assembly, thereby protecting the child from harm and the risk of drowning.
