Main trade-off
BISSELL MultiClean Allergen Lift-Off Pet
Requires manual floor-brush selection.
Head-to-head
Choose the MultiClean 2998 when you want an explicit brushroll on-off control. Choose the SurfaceSense 3418 when automatic adjustment between carpet and hard floors better matches your rooms. Both provide Lift-Off cleaning, a tangle-free main brush and sealed HEPA filtration, so those shared features alone do not justify choosing one over the other.
Before you choose
3418 is useful when a route repeatedly crosses between carpet and hard floor, but its carpet-type control still needs appropriate adjustment. Choose it to reduce one specific mode-selection task, rather than expecting every floor setting to disappear.
What this is based on
The 3418 manual states that the brush senses floor type and separately instructs use of the carpet-type control. 2998 provides its own brushroll switch plus carpet control.
Main trade-off
Requires manual floor-brush selection.
Main trade-off
No separate brush-off floor control documented in the reviewed guide.


Compare BISSELL MultiClean 2998 and SurfaceSense 3418 for manual brush shutoff, automatic floor changes, Lift-Off tools and filter cleaning.
The practical choice turns on floor brush control and crevice tool, then on the constraints in your own setup.
Winner by situation
2998 has a separate switch. 3418 relies on automatic floor adjustment.
3418 changes the floor-brush behavior automatically.
Both supply a removable pod and Pet TurboEraser.
3418 includes LED lighting in its combination attachment.
What matters in practice
3418 is useful when a route repeatedly crosses between carpet and hard floor, but its carpet-type control still needs appropriate adjustment. Choose it to reduce one specific mode-selection task, rather than expecting every floor setting to disappear.
The 3418 manual states that the brush senses floor type and separately instructs use of the carpet-type control. 2998 provides its own brushroll switch plus carpet control.
2998 is the clearer choice when you specifically need the motorized floor brush off and the surface permits vacuuming. Its manual explicitly defines that state. The 3418's automatic adjustment should not be described as equivalent to a user-selected suction-only floor mode.
2998 instructions identify brush-off cleaning for hard or delicate surfaces. The reviewed 3418 guide describes automatic sensing, with no equivalent separate brush switch.
If most pet hair is on upholstery, both packages already include a Lift-Off pod and Pet TurboEraser. The 3418's more meaningful attachment difference is its illuminated crevice tool, while SurfaceSense mainly affects time spent using the floor head.
Selected package facts establish the shared pet attachment and the LED-tool difference. Both manuals recommend attaching Pet TurboEraser directly to the hose for its intended use.

BISSELL, 2998
A bagless upright with a removable Lift-Off pod, a 30 ft cord and a manual brushroll stop. Its sealed HEPA system and included TurboEraser cover floor and above-floor jobs.

BISSELL, 3418
A bagless Lift-Off upright that automatically adapts its brushroll to the floor surface. It has a 1 L cup, sealed HEPA filtration and an LED-lit combination tool, with no manual brushroll stop.
Meaningful differences
| What changes | BISSELL MultiClean Allergen Lift-Off Pet | BISSELL SurfaceSense Allergen Lift-Off Pet | Why it matters |
|---|---|---|---|
| Floor brush control | Separate brushroll on-off switch | SurfaceSense automatic floor adjustment | 2998 gives direct brush shutoff. 3418 handles floor transitions automatically. |
| Carpet adjustment | Manual carpet-type suction control | Manual carpet-type suction control | Automatic floor sensing does not remove the 3418's separate carpet adjustment. |
| Detached cleaning | Lift-Off pod with Pet TurboEraser | Lift-Off pod with Pet TurboEraser | Both leave the floor head behind for attachment jobs. |
| Crevice tool | 2-in-1 dusting and crevice tool | LED-lit 2-in-1 dusting and crevice tool | 3418 adds local illumination for narrow attachment work. |
| Post-motor filter | Nonwashable pleated filter | Nonwashable pleated filter | Neither allows rinsing every filter during cleanup. |
| Power cord | 30 ft | 27 ft | 2998 provides 3 feet more cable, independent of the floor-sensing difference. |
What you give up
Recommendation switch
Choose BISSELL MultiClean Allergen Lift-Off Pet. 2998 has the explicit brushroll switch.
Choose BISSELL SurfaceSense Allergen Lift-Off Pet. 3418 adjusts its floor brush automatically.
What matters in practice
Picture the route from a carpeted living room to a hard-floor kitchen. 3418 uses floor sensing while 2998 asks you to choose the brush state. Direct control can be useful when following a surface-specific care rule. Automatic adjustment is useful when the supported surfaces suit the machine and repeated switching is the irritation.
The two machines share the detachable-pod format and a Pet TurboEraser attachment. The 3418's sensing system operates at the floor head, so it does not establish a better upholstery result. Look instead at whether the illuminated crevice tool addresses the actual gaps you clean and whether you prefer the floor-control system.
Both manuals allow washing the pre-motor filters and require full drying. Both prohibit washing the pleated post-motor filter. The SurfaceSense name does not change that maintenance distinction. A buyer moving between these two models can retain the same broad filter-care pattern, while checking the current replacement instructions.
