Invented by a janitor with asthma, the Hoover vacuum cleaner has been a household staple for over 100 years. But Hoover deals in much more than vacuums: the iconic company also makes carpet washers, steam cleaners, air purifiers and hard floor cleaners. Use Hoover coupons online to check out the "Specials", or at an authorized Hoover retailer including Amazon, Best Buy, Target, Walmart, Bed Bath & Beyond, Kmart and Home Depot, to help keep your home clean.
