Our first Dyson lasted 12+ years so when it came time to replace it, we researched other Dyson models. We settled on the Dyson Ball Animal 2 based on reviews. Its easy to use on our carpet and stairs. We love the high reach wand and the multi-tool is perfect for cleaning under the couch cushions. Strong suction power and easy to empty the canister.
We have had the Dyson Ball Animal 2 for three years and we have been very happy with it. We have a large chocolate lab and white carpet so a vacuum that can keep up with her shedding is a must. The Dyson Ball Animal 2 does an exceptional job getting all her fur off the carpet. It maneuvers very easily making it ideal for around furniture. The Dyson has maintained suction and continues to do a great job keeping our carpet clean. I also love the attachments that come with the vacuum. I particularly like the Tangle Free Turbine for my stairs!
We are in love with our Dyson Ball Animal 2. We still have the original, builder-grade carpet in our home and it has looked worn for months. Our Dyson is the only vacuum that fluffs up the cheap carpet (until it gets walked on, of course) and its attachments make our stairs almost look new (again, until we step on it - ha). Dysons are known to "never lose suction" -- it's their whole thing. While it is an impressive machine, it took some practice for me to learn the best way to navigate it on our stairs.
