1. Requires care: 1) pour water into the tank every day 2) drain the dirty yellow water from the bath every 2-3 days - rinse it 3) rinse the drum with a strong jet of water every 10 days (because an unpleasant swamp begins to go a smell that is not "treated" by rinsing the bath) 4) once every 3 weeks you have to COMPLETELY disassemble the drum (and there are 50 !) disks, and clean each disk with a brush and soap on both sides ! This takes 2 hours. If this is not done, there will be a swampy smell that cannot be removed by washing the bath, rinsing the drum, etc. I BELIEVE THIS IS THE MAIN DEFECT OF THE APPARATUS. Whatever I did, just not to wash these discs, the best option is to wash them in a washing machine with powder. In the dishwasher, the discs bend from temperature and do not wash well 5) Wipe the carbon filter from dust every 15-20 days.
2. The bath has a complex shape, which makes it difficult to wash it easily. In addition, in the "inaccessible areas" for the brush, plaque will soon form, which is not removed by ANYTHING.
3. It is difficult to find a place for it, so that the air circulates correctly, and it is easy to change the water, and it is easy to get the bath, and there is access to the outlet, and so that it does not interfere.
4. In winter, it practically does not moisturize, at least the effect is not felt. In the summer, the windows fogged up, and the humidity showed 60%, in winter - at least henna, 29% from October to May.
5. Drum disks eventually become covered with a yellow coating, which, probably, only cleaners in Hell will remove.
6. For its price, the design is too simple, although for me the main thing is the effect.
