The frequency of automatic range hood cleaning depends on your usage frequency. Here are a few suggestions:
First: Home range hoods: Generally, a deep cleaning once a year is sufficient. If you eat three meals a day at home and use it frequently, you can clean it every six months.
Second: Commercial range hoods: Due to their high usage frequency, they can be cleaned every 3 to 6 months.
For commercial appliances, it's not just range hoods that need cleaning; refrigerators and air conditioners also require regular cleaning and disinfection.
Not cleaning them for extended periods not only prevents them from effectively removing grease and affects their performance, but the accumulated grease can also damage the range hood's structure and shorten its lifespan.
