Query: Good Power, Bad "Quiet Mode"

This vacuum has good power and a useful Power Boost Mode that works very well. The noise is pretty loud, however, and although it does offer a "Quiet Mode," you must strain your ears to even here the slightest difference in sound. I received the vacuum in a timely fashion and was pleased with the packaging and return policy. Over all, it was a good experience buying this vacuum from this company. The only disappointment was the sound.
