The CNET testing lab in Louisville, Kentucky, has evaluated over 50 cordless vacuum models to determine their effectiveness across various surfaces. Each vacuum undergoes rigorous testing, focusing on factors such as battery life, overall usability, and specific features.
The primary evaluation method involves a straight-line test on hardwood and two types of carpet, where vacuums are assessed for their dirt collection capabilities using play sand and pet hair. This method aligns with standards set by the International Electrotechnical Commission, ensuring a fair comparison among models.
Performance ratings are broken down into several categories: 30% for performance based on dirt pickup, 25% for value relative to price, 20% for battery life, 15% for features, and 10% for user experience. Among the tested products, the Eureka ReactiSense 440 has emerged as a top performer, priced at $180, showcasing exceptional capabilities in the cordless vacuum segment.
