Yes,just that-cheaper,plastic frame motors with smaller fans and running at higher speeds.Gone are the slower speed,metal framed,larger fan motors!I don't like the screamer jet engine motors,either.Jet engines are loud-but have to be-vacuum motors should be quiet!!! |

Most of the modern bagless canister and upright vacuums has annoyingly high-pitched sound. Miele and Sebo are different thing. Electrolux also makes very pleasant sounding vacs. |

maybe the higher pitch sound comes from the new vortex type fans they use. Unless it's cheaper motor bearings. Nothing cleans like a dual fan motor, and they were quieter. |

I've often wondered if the acoustics of the plastic containers found on bagless vacs really increases the level of noise these vacs produce. The sound must resonate thru the plastic and the cyclones must also transmit the motor noise into the dust container. In contrast, bagged vacs have a nice cushiony soft fabric bag seated in a sealed compartment under a cover that often has a second layer for tool storage. This can really dampen the noise coming from the motor chamber. Added to this are the filter cartridges seated on both sides if the motor.
With regard to uprights, many of the cheaper bagless models are advertised as having the ability to clean bare floors. Bare floors don't absorb sound waves like a deep carpet does, so these screamers sound even worse on bare floors. The noise is made a lot worse if you can't shut off the brush roll. |

Cyclonic action itself causes more noise. I noticed that when I first used my cyclonic bag saver. |

Just last night I was using a clean air plastic upright, and my Mom said "That thing sounds like a Jet taking off." |

The reason being is that SEBO and Miele vacs have sound proofing added.
The EU law that stipulates vacuums must be produced now higher with 1600 watt motors may also prove to be worthwhile in the long run; they may make it to other countries regardless of the laws, thus in some cases providing a quieter motor than the previous 2000 watt motors that the previous models had. And whilst we're on the subject about noise, lets not forget the Power nozzle floor heads that canister vacs have. After all they also make an added noise. |

In this video, booth vacuums had the lower pitch, not the shrill high pitch that is so common now. I think the first one sounded a bit better though. With the second one, especially when he turned it off, it sounded like the motor might be getting ready to go out. |

Here is a video of a Kenmore whisper tone. Not sure if this was made by Panasonic or whirl pool but it definitely sounds better than the current models. |

It's nice, but too new to be Whirlpool or Ryobi. Definitely by Panasonic. |

Here's a video that demonstrates what you are talking about. You can hardly hear the canister motor, but the power nozzle is loud and clear. Also interesting to see the work he's done to restore the vacuum to like new condition. |

My mom has a Whispertone canister like the one above. The motor is a bit smaller than the older ones but still has a pleasant sound. I agree the PN adds quite a bit of noise-those ones were kind of buzzy.
My Progressive canister has an even smaller motor and a much higher pitch sound, especially with the HEPA filter. It's pretty quiet on low. My Electrolux Grand Marquis is the opposite, the machine sounds like a fighter jet roaring but you can barely hear the PN over it. New uprights with the small motors almost all sound like screamers to me. But even Elites and Bravos 20 years ago were too loud for me. |

are generally noisier than smooth belts. I don't find the Kenmore P/N that loud. |

The belts for the Power Mate power nozzle for my Kenmore Progressive & Kenmore Intuition vacuums use a thin grooved belt, like the serpentine belt in a car.

I'm not sure when these were out, but the motor sounds good with these, not that annoying high pitch scream, it's a canister called the hoover celebrity. |

yep, that Hoover QS 2 speed sure is nice. I like the 2 speed power nozzle as well. No one else offered that to my knowledge. |

This article talks about good vacuum design in general, but it mentions the trend of moving to one stage motors that spin much faster and thus will where out quicker. CLICK HERE TO GO TO n0oxy's LINK |
