It was purchased for cleaning only the internal household air conditioning units. It is used with caution as we have many years of professional experience and knowledge in handling similar tools.

Tested tool, purchased for air conditioning cleaning, its construction quality is slightly worse than that of the fontus Gen 1 while making noticeably more noise, with the corresponding advantages of course
