There is a few types of necessity's that bring us to clean the house in the compulsory way every year on arrival of the spring.
The first necessity is the feeling of tradition that whispers in our brain: "clean the house, this is what every Jewish person does and suppose to be doing from the beginning of time".
The second necessity is the sense of disgust from all the dishes (being covered in dust) that remained in the sink during the last year, smelling with an awful outer, this thing is non kosher, especially with the smell of vinegar and terrible aroma, particularly if the night of the order (pesah) arrives.
The third necessity is the happiness that approaches, in light of the fact that these periods of life are the only times that the refrigerator is actually filled with food and that there will be something different in the freezer besides a frozen pita bread. This thing gives us a little desire to contribute something back in return, and everything by in the ambience of the holiday.
The fourth and last necessity is due to the fact that you need to clean the house once in a while and if you're always giving yourself excuses then the fact that the holiday arrives is an optimal excuse to cease sitting on the bottom and maybe at least buy a broom.
