Eureka Bravos are notorious screamers. 12 amp large fan models like my 7642 ‘The Boss Bravo II’ are among the worst offenders for making too much noise. I like this vacuum but I just can’t stand the noise. I think the fan and scroll design is such that the vacuum emits rapid pulses of air kind of like a tornado siren. The tight tolerance between the edge of the impeller and its housing increases vacuum performance but at the cost of extreme noise from the exhaust into the bag.
I had enough. I cut a section of egg crate mattress topper to the same dimension as the outer bag jacket. I then placed this inside, sandwiched between the disposable bag and the outer bag. I faced the ridges of the foam toward the disposable bag with the hope this orientation would provide the most benefit. Imagine anechoic walls. As an added benefit, the ridges should allow air to flow out of the disposable bag. That said, this foam is so breathable that I think most of the air just flows through it rather than around it, anyways.
The noise reduction was not out of this world, but it did make a difference, and with no discernible impact to vacuum performance. It makes me wonder how many other vacuums could benefit from something like this. My feeling is that any number of vacuums could be made quieter with something like this.
