How long does the battery last?

Expect roughly 30 to 40 minutes on low suction and well under 15 minutes in boost mode. Runtime depends on the surface and how often the sensor raises power.

Is it good on carpet?

It handles low-pile carpet and rugs but lacks the power for deep-pile carpet. It is best treated as a hard-floor vacuum with carpet backup.

Does it come with a spare battery?

The standard package includes one 2.5Ah battery. The battery is removable, so a second one can be charged separately if you buy it.

The vacuum, the 2.5Ah battery, a charger and the usual crevice and upholstery tools. Check the listing for the exact tool set before ordering.

Is $179.99 a good price?

It is the only new price listed, at Amazon as of November 5, 2026, so there is no competing store to beat it. Watch for seasonal sales, since cordless sticks commonly drop during holiday events.

How does it compare with the ReactiSense 450?

The 450 adds more suction and a larger bin for a higher price. The 440 is the lighter, cheaper pick for small homes and quick cleanups.

Our take on the Eureka ReactiSense 440 Cordless Stick Vacuum Cleaner

The Eureka ReactiSense 440 is a cordless stick vacuum with a 2.5Ah (2500mAh) battery and a floor-head sensor that adjusts suction to the surface. It is a mid-range option for quick daily cleanups on hard floors and low-pile carpet rather than a deep-clean machine. At $179.99 at Amazon as of November 5, 2026, it sits at its only listed new price, so there is no cheaper store to compare against right now.
