Kenmore Featherlite Lift-Up DU4080 vs Shark Rotator Lift-Away NV501

The Shark Rotator NV501 is the superior choice for most households due to its higher motor wattage and consistent suction performance. While the Kenmore DU4080 is lighter and easier to carry, its suction can struggle to maintain a seal on certain surfaces. Owners highly rate the Shark for its durability and deep-cleaning power, whereas the Kenmore is preferred by those prioritizing portability and a larger dust capacity.

  • Choose the Kenmore Featherlite if you need a lightweight machine that is easy to carry up stairs and offers a larger dust cup for fewer interruptions.
  • Choose the Shark Rotator if you want a more powerful motor, longer reach with a 30-foot cord, and a proven track record for maintaining suction.

Questions and answers

Yes, the Kenmore is over 3 lbs lighter than the Shark, making the lift-up pod significantly easier to carry while cleaning staircases.
Do these vacuums help with allergies?
Both models are excellent for allergy sufferers as they both feature HEPA filters and completely sealed systems to trap 99.97% of particles.
Which model has a longer reach?
