If an appliance could change your life, this is it.
I use this vacuum several times a day, every single day, and it makes such a huge difference in our house. I keep it plugged in just around the corner in my kitchen, so it is handy but mostly out of sight. I clean up my kitchen floor and dining room pretty much after every meal, and do a quick sweep through the rest of the main floor of the house once a day.
With kids and pets, I just don't think we could get by without it. It is more expensive than most stick vacuums, but that's because it works soooo much better. It will suck up pennies and marbles and all the pet hair.
Don't be fooled by less expensive models - the lower power models don't work nearly as good and aren't worth it. This is the one you need.
