Vacuum Technology Editor
Dr. Naomi Tran is the vacuum technology editor at Vacuum Owl. She earned her Ph.D. in mechanical engineering with research on airflow and particulate filtration, and has spent her post-academic career translating that physics into writing for general audiences. Naomi owns every "what is" explainer on Vacuum Owl - what separates a robot from a stick vacuum, what true-HEPA actually filters, why "Pa" and "air watts" measure different things, how LiDAR and vSLAM let a robot map a room. She also fact-checks every suction, filtration, and spec claim in the Buying Guides and Brands articles, because that's where marketing numbers most often go unchallenged. Her test bench includes an anemometer and a particle counter she uses to sanity-check manufacturer airflow and filtration claims. Naomi lives in the US Bay Area, where the vacuum in her apartment is a cordless stick she chose on filtration, not suction headline numbers.
