Main trade-off
Kenmore Featherlite Lift-Up
Shorter published attachment reach.
Head-to-head
Choose the DU4080 when washable exhaust filtration and less frequent scheduled primary-filter washing suit your routine. Choose the DU3017 for its longer attachment reach and included Pet HandiMate. Both have a 25-foot cord and detachable pod, but their filter instructions differ enough that a shared cleaning routine would be a mistake.
Before you choose
DU3017 gives 2 feet more published attachment reach, useful when a shelf or stair tool is just beyond the DU4080's reach. It does not add electrical reach across the room, because both power cords are 25 feet.
What this is based on
11 minus 9 equals 2 feet of attachment reach. Cord lengths are equal. Actual usable reach still depends on hose tension, routing and stable machine placement.
Main trade-off
Shorter published attachment reach.
Main trade-off
Primary filter washing is specified at least monthly.


Compare the Kenmore DU4080 and DU3017 for bagless Lift-Up cleaning, hose reach, included pet tools and exact filter-maintenance routines.
The practical choice turns on attachment reach and included tools, then on the constraints in your own setup.
Winner by situation
DU4080 specifies every 3 months. DU3017 specifies at least monthly. Dirty filters can need attention sooner.
DU3017 lists 11 feet of attachment reach and includes a fan tool.
Only DU4080's exact instructions permit washing that filter.
DU3017 includes Pet HandiMate. DU4080's selected package lists a standard upholstery tool.
What matters in practice
DU3017 gives 2 feet more published attachment reach, useful when a shelf or stair tool is just beyond the DU4080's reach. It does not add electrical reach across the room, because both power cords are 25 feet.
11 minus 9 equals 2 feet of attachment reach. Cord lengths are equal. Actual usable reach still depends on hose tension, routing and stable machine placement.
A buyer accustomed to washing every filter should pay particular attention to DU3017. Its exhaust filter is replace-only when dirty, while DU4080 explicitly permits cold-water washing. Washing DU3017's exhaust filter is outside its instructions.
The exact manuals distinguish primary filters from HEPA exhaust filters. The DU4080 yearly interval is a care schedule, not a prediction of filter life or lower ownership cost.
DU3017 supplies a rotating Pet HandiMate for fabric surfaces while DU4080 supplies an upholstery tool. That makes DU3017 a more complete starting package for a sofa-heavy routine, without establishing better floor pickup.
Selected package contents identify the tools. Both detach their body for attachment use. No matched upholstery test or guaranteed hair-removal rate is published here.

Meaningful differences
| What changes | Kenmore Featherlite Lift-Up | Kenmore Crossover Max | Why it matters |
|---|---|---|---|
| Power cord | 25 ft | 25 ft | Electrical reach is shared, so it cannot break this tie. |
| Attachment reach | 9 ft | 11 ft | DU3017 adds 2 feet of published attachment reach without changing the 25-foot power cord. |
| Included tools | 3-in-1 combination and upholstery tools | Pet HandiMate, 2-in-1 combination and rotating fan tool | Match the package to fabric and overhead cleaning rather than treating tool count as performance. |
| Exhaust filter care | Cold-water wash yearly, then dry fully | Do not wash, replace when dirty | These exact models require different HEPA-filter maintenance. |
| Primary filter care | Foam and felt wash every 3 months | Primary filter wash at least monthly | DU3017's manual calls for more frequent scheduled primary-filter washing. |
What you give up
Recommendation switch
Choose Kenmore Featherlite Lift-Up. DU4080 permits exhaust-filter washing and specifies three-month foam-and-felt care.
Choose Kenmore Crossover Max. DU3017 includes the specialized tools and has longer published attachment reach.
What matters in practice
Both have a 25-foot power cord, so there is no electrical-reach upgrade between them. DU3017 instead extends the published attachment reach from 9 to 11 feet. That distinction matters for reaching a shelf from a stable position. It does not prove that either vacuum can clean a whole staircase without relocation.
The DU3017 manual calls for primary-filter washing at least monthly and prohibits washing its exhaust filter. DU4080 separates a three-month foam-and-felt schedule from yearly exhaust-filter washing. These instructions change the parts and drying routine you need to organize. They do not establish the total time or cost of maintaining either vacuum.
Both models separate the pod from the floor nozzle for attachment work. DU3017 supplies more specialized tools for that mode, including Pet HandiMate and a fan attachment. DU4080 is adequate when a basic upholstery and combination tool cover the actual jobs. Check the exact box before using an accessory photograph as a reason to buy.
