I have an old Eureka Model 1406 upright vacuum, the one that exactly imitates the old Hoover models after their patent ran out. It's really powerful, and still works great, except that the brush roller is worn out.
The original roller contains both brushes and beater bars. Apparently I can still get a replacement, but wondered if the vacuum might work better if the roller was all-brush, with no beater bars. This would be for fairly deep carpet. I guess I never understood exactly what the beater bar was supposed to do.
Any opinions would be appreciated.
