Here is an efficient vacuum that captures more dust than any other cyclone and does not require you to change a filter. The Dyson Cinetic Big Ball is developed to capture a ton of dust and dirt. It comes with a self righting design, which means it gets back up on its own. The articulated handle gives you more control.
This vacuum cleaner does not require you to wash or replace a filter. It comes with a carbon fiber turbine tool for every floor type. The above video shows what you get.
