When a parent picks up their child from school they expect their child to look the same way they were dropped off. When children participate in art activities requiring the use of paint, and glue, etc.; they tend to have expected accidents. With the use of the portable sink you are able to wheel the sink to the child immediately without the child having to get up and walk causing additional messes on the vinyl or carpeted floor, and proceed to clean the child up. When children participate in the outdoor activities they can sometimes find a little dirt or better yet a little dirt may tend to find them; therefore, clothing and sometimes shoes tend to get dirty. With  portable sinks, a daycare worker can immediately wheel the sink to the child covered in soot outdoors and get that child cleaned up prior to the child being picked up by their parent or guardian.
