The catch
BISSELL MultiClean Allergen Lift-Off Pet
Calls for manual floor-brush selection.
Side by side
For a brushroll you switch on and off yourself, go with the MultiClean 2998. If your rooms are better served by automatic adjustment between carpet and hard floors, go with the SurfaceSense 3418. Lift-Off cleaning, a tangle-free main brush and sealed HEPA filtration come on both, so none of those is a reason to pick one over the other.
Before you buy
3418 helps when your route keeps crossing between carpet and hard floor, though its carpet-type control still needs the right adjustment. Pick it to cut down one specific mode-selection task. Do not expect every floor setting to vanish.
Where this comes from
According to the 3418 manual, the brush senses floor type, and the manual separately tells you to use the carpet-type control. 2998 has its own brushroll switch as well as a carpet control.
The catch
Calls for manual floor-brush selection.
The catch
The reviewed guide documents no separate brush-off floor control.

A separate switch is on 2998, while 3418 relies on automatic floor adjustment.
The floor-brush behavior on 3418 changes by itself.
A removable pod and Pet TurboEraser come with each.
The combination attachment on 3418 has LED lighting built in.
In practice
3418 helps when your route keeps crossing between carpet and hard floor, though its carpet-type control still needs the right adjustment. Pick it to cut down one specific mode-selection task. Do not expect every floor setting to vanish.
According to the 3418 manual, the brush senses floor type, and the manual separately tells you to use the carpet-type control. 2998 has its own brushroll switch as well as a carpet control.
When you specifically need the motorized floor brush off and the surface permits vacuuming, 2998 is the clearer choice. Its manual explicitly defines that state. The automatic adjustment on the 3418 shouldn’t be called equivalent to a suction-only floor mode that the user selects.
The instructions for 2998 identify brush-off cleaning for hard or delicate surfaces. The 3418 guide that was reviewed describes automatic sensing and has no equivalent separate brush switch.
When most pet hair is on upholstery, each package already includes a Lift-Off pod and Pet TurboEraser. The more meaningful attachment difference on the 3418 is its illuminated crevice tool, and SurfaceSense mostly affects the time you spend using the floor head.
The shared pet attachment and the LED-tool difference come from the facts about the selected packages. For its intended use, both manuals recommend attaching Pet TurboEraser straight to the hose.

BISSELL, 2998
This bagless upright has a removable Lift-Off pod, a 30 ft cord and a manual brushroll stop. A sealed HEPA system and an included TurboEraser let it handle both floor and above-floor jobs.

BISSELL, 3418
The brushroll on this bagless Lift-Off upright adjusts itself to the floor surface. It comes with a 1 L cup, sealed HEPA filtration and an LED-lit combination tool, but no manual brushroll stop.

| Detached cleaning | Lift-Off pod with Pet TurboEraser | Lift-Off pod with Pet TurboEraser | For attachment jobs, each leaves the floor head behind. |
| Crevice tool | 2-in-1 dusting and crevice tool | LED-lit 2-in-1 dusting and crevice tool | Narrow attachment work gets local illumination on 3418. |
| Post-motor filter | Nonwashable pleated filter | Nonwashable pleated filter | Rinsing every filter during cleanup isn’t allowed on either. |

Trade-offs
Change of plan
Go with BISSELL MultiClean Allergen Lift-Off Pet. The explicit brushroll switch is on 2998.
Go with BISSELL SurfaceSense Allergen Lift-Off Pet. The floor brush on 3418 adjusts by itself.
Decision guide
Pick the MultiClean 2998 if you want a clear on-off control for the brushroll. Pick the SurfaceSense 3418 if automatic adjustment between carpet and hard floors is a better match for your rooms. Since Lift-Off cleaning, a tangle-free main brush and sealed HEPA filtration are shared, those features alone should not tip the decision.
Imagine walking from a carpeted living room into a hard-floor kitchen. The 3418 relies on floor sensing, whereas the 2998 leaves the brush state to you. Having direct control helps when a surface has its own care rule. Automatic adjustment helps when the surfaces are ones the machine supports and having to keep switching is what annoys you.
Both machines use a detachable pod and come with a Pet TurboEraser attachment. Because the sensing system on the 3418 works at the floor head, it says nothing about better upholstery results. Ask instead whether the illuminated crevice tool suits the gaps you really clean, and which floor-control system you prefer.
Washing the pre-motor filters is allowed in both manuals, as long as they dry completely. Washing the pleated post-motor filter is prohibited in both. The SurfaceSense name makes no difference to that split. Someone switching from one model to the other can follow the same general filter-care pattern, but should check the current replacement instructions.
