Head-to-head
Kenmore DU4080 vs Shark Detect LA492: Kenmore eases upstairs carrying, Shark automates mixed-floor changes
The short answer
Choose Kenmore DU4080 when carrying the whole vacuum upstairs and manually stopping the brush matter most. Choose Shark LA492 for automatic floor response and a self-cleaning floor brush during daily mixed-floor sessions.
Before you choose
The reasoning and the trade-offs
Carrying upstairs favors the lighter complete cleaner
Kenmore specifies DU4080 below 12 lb and Shark lists LA492 at 13.12 lb. The published full-unit figures put Kenmore more than 1.12 lb lighter. That helps with carrying the complete vacuum between floors. Detached pod weight and comfort on the stairs remain unmeasured.
What this is based on
13.12 minus a value below 12 gives a difference greater than 1.12 lb.
Main trade-off
Shark Detect Lift-Away ADV
Heavier full-unit specification.

What matters in practice
The differences that matter
Carrying upstairs favors the lighter complete cleaner
Kenmore specifies DU4080 below 12 lb and Shark lists LA492 at 13.12 lb. The published full-unit figures put Kenmore more than 1.12 lb lighter. That helps with carrying the complete vacuum between floors. Detached pod weight and comfort on the stairs remain unmeasured.
How we reached this conclusion
13.12 minus a value below 12 gives a difference greater than 1.12 lb.
A floor sensor is different from choosing zero brush rotation
DU4080 gives you manual brush shutoff for bare-floor work. LA492 changes brush speed according to the detected surface. Choose Kenmore when the floor-care instructions require suction with the brush stopped. Choose Shark when automatic transitions suit the flooring you have confirmed it can clean.
How we reached this conclusion
Manual shutoff is documented for Kenmore. Automatic speed response alone does not establish brush-off behavior for Shark.
The carpet brush does not clean the cat tree
Both can carry a detached pod to furniture, but their supplied tool sets differ. Kenmore lists Pet HandiMate. Shark lists Pet Multi-Tool and crevice and dusting tools. Compare the tool that touches your fabric before prioritizing the Shark floor brush. No timed sofa-hair test establishes a winner.
How we reached this conclusion
Floor-brush features and supplied hose tools are separate facts.

Meaningful differences
What changes the fit
| What changes | Kenmore Featherlite Lift-Up | Shark Detect Lift-Away ADV | Why it matters |
|---|---|---|---|
| Whole-unit weight | Under 12 lb full unit | 13.12 lb full unit | These are full-unit claims, not detached-pod weights. |
| Floor control | Manual brushroll shutoff for bare floors | Floor Detect varies brush speed and Direction Detect changes suction routing | A dedicated stop and automatic speed changes solve different concerns. |
| Portable configuration | Lift-Up pod for hose and accessory cleaning | Standard Lift-Away pod for hose and accessory cleaning | Both detach for tool cleaning, without a powered floorhead claim here. |
| Included fabric tools | Pet HandiMate and 3-in-1 combination tool | Pet Crevice Tool, Pet Multi-Tool and Anti-Allergen Dust Brush | Kenmore supplies Pet HandiMate while the Shark set uses passive pet tools. |
| Power cord | 25 ft cord | 25 ft cord | Both have the same nominal cord length. |
