The biggest difference between a spring cleaning and a normal cleaning is the depth of the job. By providing a really, thoroughly deep clean, the aim is to get any home into the cleanest possible state. While typical cleaning around the home might involve simply tidying up after yourself, this kind of solution aims to go beyond that and offer a really, truly deep cleaning service.
Because of this difference in style of cleaning, it can often be a far longer process than a simple cleaning solution might otherwise be. The time it takes in order to ensure that a spring clean is done properly will obviously vary from home to home, but people can expect it to be far longer and far more dedicated than the traditional cleaning operation might otherwise be.
