Having used a Sebo D-series vacuum last year, I don't sneeze after vacuuming more. The bags are easy to assemble and easy to dispose of. Allergy sufferers will appreciate this machine and bag filter. Once I lost a diamond and couldn't find it. I vacuumed the bedroom then opened the top of the vacuum and here it is. The bags are a bit more expensive but I save by not having to take any medication.
