Try the Sensor 12, or Sensor 15, German made HEPA vacuum cleaners that trap 99.97 per cent of all the dust/dirt it vacuums up. I bought mine at a janitorial supply store. One is 10 years old and works like new, the other is 1 year old and is left on a job site where it is used 2 hours every day. Wonderful machines. Hospitals, hotels, motels, use this vacuum extensively.
