Black+Decker Dustbuster FLEX
Score: 74/100
Bissell AeroSlim
Score: 56/100Rankings
The BLACK+DECKER BDH2020FL FLEX combines a 20 V cordless system with a four-foot flexible hose and strong suction, making it effective on pet hair and hard-to-reach spots. At 1.45 kg and only 15 minutes of runtime, it can feel heavy and requires frequent recharging. It's a good match for pet owners and car interior cleaning where reach matters more than endurance.
The Bissell AeroSlim 29869 is a cordless handheld vacuum known for its ultra-lightweight design and integrated crevice and dusting tools. Its trade-offs include a very short 12-minute runtime and a tiny 0.1 L dust cup, limiting its use to quick spot clean-ups. Best suited for users needing a portable, quick-clean solution for cars and countertops.

Professional reviewers commend the BDH2020FL for its strong suction, ergonomic design, and versatile accessories that excel at pet hair and hard-to-reach spots. However, they note the short 15-minute battery life, noticeable noise, and heavier weight compared with ultra-light competitors.
Everyday users praise the flexible hose, large dustbin, and effective pet-hair pickup, but repeatedly criticize the limited runtime, loud operation, and the need for two-handed handling with attachments.
Professional reviewers such as Consumer Reports note the AeroSlim's ultra-light weight and compact size, but they do not provide detailed performance scores. Their commentary highlights the 7.4-volt lithium-ion battery and the very small dustbin, suggesting the unit is best suited for brief, light-duty clean-ups rather than extended use.
No consumer reviews or ratings were found in the research, so everyday user sentiment cannot be determined.
