The catch
BISSELL PowerClean FurGuard
The brushroll-care feature is the reason you carry the heavier listed vacuum.
Side by side
FurGuard is the choice when hair wrapped around the floor brush keeps sending you back to maintenance. ReactiSense 440 is the choice for its lighter listed complete weight and automatic dirt response. Neither maximum-runtime headline reflects a long Turbo session. Manufacturer Turbo maxima are up to 12 minutes for FurGuard and up to 15 for Eureka, and they are not matched endurance results.
Before you buy
The floor roller is what FurGuard addresses, whereas ReactiSense responds to dirt it detects while vacuuming. A family with long hair may value roller care. A route that alternates light dust and tracked-in grit may gain more from sensing. Neither feature proves better pickup in a head-to-head that has not been tested.
Where this comes from
BISSELL PowerClean FurGuard: FurGuard self-cleaning roller. Eureka ReactiSense 440 NEC440BK: ReactiSense automatic dirt response.
The catch
The brushroll-care feature is the reason you carry the heavier listed vacuum.
The catch
FurGuard’s specific roller mechanism is not something automatic dirt response adds.

BISSELL FurGuard vs Eureka ReactiSense 440 comes down to roller hair care or automatic dirt response. The short high-power runtimes are compared as well.
Which one fits
The specific maintenance mechanism comes with FurGuard.

ReactiSense takes care of the power response.
Up to 12 and 15 minutes are the published Turbo maxima, and no matched duration test backs them.
In practice
The floor roller is what FurGuard addresses, whereas ReactiSense responds to dirt it detects while vacuuming. A family with long hair may value roller care. A route that alternates light dust and tracked-in grit may gain more from sensing. Neither feature proves better pickup in a head-to-head that has not been tested.
BISSELL PowerClean FurGuard: FurGuard self-cleaning roller. Eureka ReactiSense 440 NEC440BK: ReactiSense automatic dirt response.
In Turbo, the current manuals list up to 12 and 15 minutes, respectively. Neither figure is a matched endurance test, and both fall short of the maximum-runtime headlines. For a long high-power carpet round, a suitable spare battery and a planned bin check count for more than treating either maximum as a whole-home guarantee.
BISSELL PowerClean FurGuard: Up-to-12-minute Turbo claim and removable pack. Eureka ReactiSense 440 NEC440BK: 15-minute Turbo runtime and removable pack.
Eureka’s complete-machine figure comes in about 12% lower, which is a 0.91-pound difference. That is handy for carrying the stick upstairs. Once the hand unit is detached the configuration changes, so the same percentage advantage is not established on a fabric seat.
BISSELL PowerClean FurGuard: 7.3-pound complete configuration. Eureka ReactiSense 440 NEC440BK: 6.39-pound complete configuration.

BISSELL, 4039
This dry pet stick has a removable battery and comes with a powered FurFinder upholstery tool for compatible fabric. It can stand up by itself, but only as a short, supervised pause on a suitable hard surface.

Eureka, NEC440BK
A HEPA stick that responds to sensors, with a detachable battery, an anti-tangle nozzle and runtime figures listed separately for low, medium and high.
