This is the second Zing I have bought. I thought the first one finally died after 7 years, so I ordered a new one. Come to find out the old one is just fine. It was the outlet I had plugged it into. Now I have one for upstairs and one for downstairs. Can't beat the performance for the price. I have a cat and this vacuum picks up all of his dander and my hair extremely well. Works great on carpet and bare floors. The only drawback I have found is the bags seem to only be available online.
