Even the best vacuum will break down and need to be replaced. So what to do with your old one? You can recycle it. Best Buy will take your old vacuum (in addition to a whole host of other electronics) and recycle it, free of charge. Just bring it to one of the store's retail locations, and it'll handle the rest. And if you’re in the market for a new vacuum, follow Best Buy on social media (@bestbuy), where it periodically announces discounts if you recycle an electronic. A recent post offered a 20 percent discount on a new Dyson if you brought in your old vacuum to be recycled.
