We have two medium sized dogs that shed A LOT. This vacuum has done an excellent job of keeping the hair in our house to a minimum. We've had it for several months now and occasionally I'll look closely at the carpet after vacuuming to see if anything has changed in terms of suction. So far there is still no visible hair once I've finished vacuuming. The power eraser tool is also great for cleaning our stairs, and the vacuum is light enough for me to easily pack it up and down them.
