I bought this vacuum for my unit, which has a mix of tiles and carpet. My youngest daughter has issues with loud sounds too, so I did a lot of research. This vacuum is amazingly quiet, it can get to every corner of my home with the long on-board lead and it's INTENSELY powerful. I've not needed to go past 1/4 power, even when getting glitter out of the carpets. I can't rate this vacuum highly enough. I've owned 2 Vax vacuums and 3 different Dysons over the years. This Miele makes everything else look like toys. I would never buy another brand again, not I think I'll ever need to replace this one, as it's sturdy, easy to clean, easy to maneuver and store and feels as though it will last the marathon. Super happy I made this choice and it's worth every cent.
