Performance and Filtration
The ReactiSense is powered by a 350W motor that generates up to 25,800 Pa of suction, aimed at removing dust, pet hair, and debris from both carpets and hard floors. It uses a 7-cone cyclonic separation system to reduce clogging and maintain consistent suction. A fully sealed design, paired with an H13 HEPA filter, captures up to 99.95% of microparticles, helping keep indoor air cleaner.
Designed for Homes with Pets
To address a common issue in pet households, Eureka has introduced a new anti-tangle brushroll. Built with fins and comb strips, it actively minimizes hair wrap during use. This reduces manual maintenance and helps the vacuum operate smoothly over time.
Smart Cleaning Features
The vacuum includes Smart Sense+React Technology, which detects dust levels and automatically adjusts suction power. It also adapts brushroll speed when transitioning across different surfaces such as hardwood, tile, and carpet. This feature aims to improve cleaning efficiency while extending battery life.
Runtime and Versatility
On a single charge, the ReactiSense offers up to 60 minutes of runtime, with Eureka estimating coverage of around 1,600 square feet in low-power mode. A detachable battery is available separately to extend cleaning sessions. The vacuum can also convert to a handheld device and comes with multiple attachments for different cleaning tasks.
