How long does the battery really last?

Eureka rates it at up to 60 minutes, which applies at the lowest suction setting. Expect noticeably less at maximum power, so a spare battery helps for large homes.

Does it work on carpet and hardwood?

Yes. The Sense+React sensors detect the floor type and adjust brushroll speed, and the anti-tangle brushroll is designed for hardwood, carpet and tile.

What comes in the box?

The vacuum, a charger, a crevice tool, an upholstery brush and a wall mount. A spare battery is not included.

Is the battery replaceable?

Yes. The lithium-ion battery detaches, so you can charge it separately or swap in a spare.

Is it good for allergy sufferers?

The HEPA filter with Complete Seal Technology captures over 99.95% of dust and allergens, which suits allergy-prone homes.

Is the ReactiSense 440 worth it?

Yes for most homes. It pairs 25,800 Pa suction and sealed HEPA filtration with automatic brushroll adjustment, features budget stick vacuums often skip. The trade-off is runtime at full power.
