Kenmore DU4399 Featherlite Bagless Upright Vacuum

Kenmore DU4399 Featherlite Lift-Up Bagless Upright Vacuum: Full-Home Cleaning Reimagined

The Kenmore DU4399 Featherlite is proof that a full-sized upright vacuum doesn't have to be heavy, cumbersome, or frustrating to use. Coming in under 12.5 lbs and packed with smart features like Lift-Up technology, an automatic Hair Eliminator brushroll, and a completely sealed HEPA filtration path, the DU4399 is designed to handle the rigors of daily whole-home cleaning without the physical strain traditionally associated with upright vacuums. Whether you're dealing with pet hair, carpeted stairs, cluttered living spaces, or the kind of embedded dust that builds up in carpet fibers over time, the Kenmore Featherlite is engineered to tackle it all with confidence.

Lightweight Full-Size Power: Under 12.5 lbs

One of the most compelling attributes of the Kenmore DU4399 is its weight. At under 12.5 lbs, this is a full-sized, dual-motor upright vacuum that weighs less than many single-motor competitors. For anyone who has experienced the back strain and fatigue of pushing a heavy upright vacuum through an entire home, or struggled to carry a full-sized machine up a flight of stairs, this weight reduction is a genuine quality-of-life improvement. The Featherlite design doesn't sacrifice suction performance to achieve this lightness — the dual-motor configuration ensures that both the suction and the brushroll operate with independent, optimized power.

Lift-Up Technology: One Vacuum, Two Cleaning Modes

The DU4399's most distinctive feature is its Lift-Up technology, which allows the main cleaning pod to detach quickly and easily from the floor unit. This transforms the vacuum from a floor-cleaning upright into a compact, maneuverable handheld-style unit in seconds — perfect for cleaning stairs, upholstery, shelves, and above-floor surfaces. The transition is fast and tool-free, meaning you don't lose momentum during a cleaning session. The floor unit remains in place while the pod handles elevated cleaning tasks, making the DU4399 one of the most versatile upright vacuums in Kenmore's lineup.

Hair Eliminator Brushroll: No More Manual Hair Removal

For households with pets or long-haired family members, hair-clogged brushrolls are a constant headache. The Kenmore DU4399 features a proprietary Hair Eliminator brushroll system that automatically removes hair from the brushroll during operation, keeping the spinning brush free of tangles without requiring you to stop, flip the vacuum over, and cut hair loose with scissors. This is one of the most practical innovations in the DU4399's design — it saves time, reduces maintenance effort, and ensures the brushroll is always operating at peak effectiveness for carpet deep-cleaning. For pet owners especially, this feature alone makes the DU4399 a standout choice.

Triple-Capacity Dust Cup and HEPA Sealed Filtration

The DU4399 boasts a 3-liter dust cup with 3x more capacity compared to standard single-motor uprights. A larger dust cup means fewer interruptions to empty the vacuum during cleaning sessions, allowing you to cover more ground on a single pass. When it is time to empty, the bagless design makes disposal clean and straightforward. Filtration is equally impressive: the completely sealed air path ensures that all air passing through the vacuum is directed through the HEPA filter before being exhausted. This HEPA filter traps 99.97% of particles down to 0.3 microns in size — capturing fine dust, pollen, mold spores, and pet dander rather than recirculating them into your breathing air. For allergy sufferers, this sealed HEPA system is particularly valuable.

Included Cleaning Attachments

The Kenmore DU4399 ships with a thoughtful selection of cleaning tools: a Pet HandiMate tool for targeted pet hair pickup on furniture and tight spaces, an upholstery tool for gentle above-floor surface cleaning, and a 3-in-1 combination tool that handles dusting, crevice cleaning, and brush applications from a single accessory. These tools connect easily to the Lift-Up pod for seamless above-floor cleaning without switching between multiple vacuum systems.

Who Is the Kenmore DU4399 Best For?

The Kenmore DU4399 Featherlite is an excellent choice for homeowners who want a full-featured upright vacuum without the bulk and weight of traditional models. It's especially well-suited to pet owners who need the Hair Eliminator brushroll and Pet HandiMate tool, allergy sufferers who require sealed HEPA filtration, multi-floor homes where stairs cleaning is a regular task, and anyone who wants the convenience of Lift-Up above-floor cleaning in a single machine. With over 3,200 customer ratings and a proven track record, the Kenmore DU4399 is a dependable, feature-rich choice for whole-home carpet and floor cleaning.
