Previous vacuum lasted 30 years! Purchased Dyson 9/22.  I have 3 cats.  I am so pleased with my new Dyson 11.  Favorite features are cordless, compact - no canister to lug around and up/down stairs, no bumping into furniture, effective, laser light.  I have hardwood, and laminate throughout home with throw rugs at outside doors and at sink/stove.  My Dyson handles both surfaces with one pass so I spend less time vacuuming.  This is why battery lasts long enough to do whole house.  The amount of micro dust swept up is amazing.  One dissatisfaction is the weight of the battery.  I’ve switched to all battery style yard equipment and most of my batteries weigh less than the Dyson unit.  Having had two broken wrists and being 74 yrs old this weight is a bit much when using on furniture and in car.  I hope Dyson can rework the battery weight without compromising this effective vacuum.
