Dyson V15 Detect Cordless Vacuum: Save$150

View now at Walmart

I splurged on a Dyson V15 Detect vacuum over a year ago, and it's been one of my favorite home purchases. It's got a long battery life, and I love being able to see all of the gross things it's picking up. With a toddler prone to throwing food and a constantly-shedding cat in the house, it's been a lifesaver to pull out of the closet at a moment's notice and not have to worry about plugging it in.

The Dyson is also super easy to empty without getting any mess on yourself. I use it on carpet, hardwood, and tile floors, and it works great.
