The Eureka ReactiSense NEC440BK is a cordless stick vacuum with automatic suction and brush-speed adjustment based on detected dust and floor type.

## Before you buy

- Runtime claims are mode-specific: up to 60 minutes is stated for Low Mode, while another details field lists 1 hour without specifying a mode. The description also calls the 440 an upgraded model with a larger bin, enhanced attachments and more High-mode runtime, but these claims are not reconciled with the NEC440BK listing details, which specify 0.5 liters and do not substantiate those additions. Treat the HEPA performance percentage and anti-tangle effectiveness as manufacturer claims. Check the selected listing for the exact model configuration and included tools before purchase.
