Aria vacuum cleaner is the result of years of careful planning on both the creative and functional level. We have created a machine that offers a sleek design that provides the highest quality performance and filtration along with exceptional versatility and whisper quiet sound levels. The highly efficient vacuum motor, engineered and built by sister company Rotafil, well exceeds the once thought impossible 1,000 hour mark. An amazing number when you consider the average vacuum cleaner is used less than 50 hours per year. The sophisticated electronic control gradually turns on the machine providing the ability to regulate the vacuum power while monitoring the motor temperature. The full size deluxe on-board tools include an upholstery tool with removable bristles, full length crevice tool and round swivel dusting brush with natural bristles. The 3 liter Micropor Hepa style bag in addition to other stages of filtration brings the Aria to a total of 5 levels of filtration which assures excellent protection against dust mites, pollens etc. For people with serious allergies, Aria can be equipped with the Lindhaus S-Class Hepa filter (optional) which assures 99.97% of filtration efficiency at 0.3 micron. The Aria returns this purified air into the room through an exclusive draft free clean air ventilation system built into the 360 degree bumper. This design eliminates harmful unfiltered vacuum cleaner exhaust.
