I am not sure I would buy this one. The ventilation is very minimal and cleaning the inside looks difficult, the box allows cleaning of some areas but I don't see how you get into clean the whole inside unless you crawl thru that side hole.
How do you get into the house to clean it? Do you have to crawl through that little hole? The ventilation looks non - existent. In the summer there needs to be more airflow. I would not buy this one.
