Founded by David Oreck in 1963, the Oreck Corporation is one of the most respected vacuum manufacturers in the world. They sell products on four continents and have a reputation for high-quality cleaning equipment. The company started out making vacuums for the hotel industry, but quickly branched out in the home market with their lightweight vacuums.

More than 50,000 hotels still use their vacuums because of their light nature and easy-to-use functionality. Millions of consumers also use Oreck vacuums, making them one of the highest selling products on the market today. In addition to vacuums, Oreck also makes accessories, air purifiers, cleaning products, and more.

Perhaps the most well-known Oreck product is their Oreck XL® 8 lb. upright vacuum. This vacuum is their standard seller, with variations in hypoallergenic and HEPA filter options as well. The Oreck XL, like the name says, only weighs eight pounds and is known for its durable construction. Standard vacuums come with a three-year warranty and their patented filter knit filtration.

Capitalizing on the demand in the market for HEPA filter products, Oreck's XL 21 is their newest vacuum in the upright line. It features HEPA-Celoc® hypoallergenic filtration, which is designed to remove 99.9 percent of all allergens from your home's floor and air. It has an adjustable speed motor and comes with 21 free tune-ups and a 21-year warranty, one of the highest in the entire industry.
