Great product to use as a short gun for power washers needed in tight areas. What makes our school different than any other school in the country is that we teach you more than just exhaust hood cleaning for the same price as your hood cleaning and certification. This is because we believe the more services you offer to the same restaurant, which we call bundling, the higher your chances to make money while helping you rise above your competition. We also provide you with unlimited support for the first year after your training! Once you become an MFS student, we will stay by your side as your free consultant with unlimited phone support to help you with everything you need to grow your business. Please see this link which shows more details on how we are vastly different than any other hood cleaning school in the country! Kitchen Exhaust Hood Cleaning is a recession proof business because all restaurants across the country MUST clean their hood system periodically or the grease from the cooking builds up so much that it becomes a fire hazard to the restaurant. Thus, fire inspectors throughout the USA and Canada will inspect all commercial kitchen exhaust hood systems to make sure that they are cleaned prior to the grease build up. As long as restaurants cook food, this industry will always exist whether the economy is slow or thriving. Not only is Restaurant Kitchen Exhaust Hood Cleaning a recession proof business and required by ALL restaurants but also the cleaner has to be a certified entity! This means that restaurants will always want your service because they can't clean it themselves! The other great thing is that it's typically done at night after 10 pm when the restaurant closes. Thus, it can be a great part time or full-time business. And it's a business you can operate from your home, van or trailer without the need of an office or many employees.
