A user reviews the Electrolux EL7020B Oxygen 3 Ultra Canister Vacuum: “I purchased an Electrolux EL7020B Oxygen 3 Ultra Canister Vacuum Cleaner and have been using it for a little over a month. At this point I am totally thrilled with the product for the price. I have owned Exectrolux products in the past that were more expensive and a hoover product for about the same price. To say the least I am back to Electrolux. I love being able to go under furniture, and being able to disconnect head and use in tight or unusual spots with various attachments. We have a dog and the Electrolux EL7020B Oxygen 3 Ultra Canister Vacuum Cleaner is a wonderful fur finder! The filtration systems are great for keeping dust and dirt where it belongs once it is sucked up. I’ll never stray from Electrolux again.”
