Make that Allerx, instead of Mitex.
It is a Kirby vacuum with an ultra light fitted, you can also purchase a handle for doing carpets if required.
Not all UV lights are the same.
They put out different frequencies.
The one that knocks over the house dust mite is a medical uv, not sure how many nano whatever it puts out, & I can't be bothered going downstairs to check it :roll:
The beater bar also plays an important part.
Put your hand on the mattress in front of the machine and you will feel the mattress vibrating.
This assists in releasing the crap clinging to the inside of the mattress and allows the vacuum to extract it into the hepa bag.
