The Electrolux UltraFlex canister vacuum has a cool, modern design and moves well. The base of this lightweight canister vacuum has large wheels that glide smoothly on carpet and hardwood, which makes up for its lack of self-propulsion. In cleaning and suction, it was right around the middle of our lineup. We tested the vacuum's ability to pick up fine dust by spreading flour on carpet. The Electrolux required three or four passes to clean the entire area, which is sufficient but not as powerful as the best canister vacuums.
We gave this canister vacuum cleaner high marks in maintenance. The vacuum is bagless, so you don't have to worry about purchasing more bags in the future. The canister snaps off the base easily and has walls that don't trap a lot of dust or debris. The majority of the dirt fell right out and didn't need a lot of digging from us, earning the vacuum our second-best grade for maintenance in the lineup.
The noise level is on the high side. We measured the vacuum at 82 dB, which is over 10 dB louder than the quietest vacuums. The power cord is quite short at 21 total feet. That sounds like a lot, but you'll notice the difference as you move from room to room. It's about 4 feet shorter than the longest cord available.
Our biggest concern with the Electrolux is the cost of its filter. You can expect to replace a filter about twice a year to keep the vacuum fully functional, and the cost of this filter is the highest in the lineup. You should expect to fork over a few bucks every six months if you don't want a lot of dust and allergens escaping every time you vacuum the house.
More on Vacuums
The vacuum has a full range of attachments and a good five-year warranty on parts and service. The website has all the tools you need if any problems arise, though the manufacturer doesn't offer online chat. It's likely a service you won't need, but it's nice to have if something gets jammed into the head of the vacuum.
The Electrolux UltraFlex can handle all the messes you find around your house and has a great, convenient canister. However, it has one of the highest price tags and will continue to cost you more with its expensive filters.
