Review on 🌪️ Revolutionizing Cleanliness: Introducing the Beyond BLACK+DECKER Cordless Dustbuster! by Mark Ponnusamy

It offers good suction as others have noted, but the design of this model is so ridiculous that it's amazing, which is why a lot of people think it's great. As mentioned, the rubber valve is there to seal the contents in after it's been sucked in and will not get in the way of the filter bag unless you intentionally crumple the bag. And even more pointless, since the vacuum is stored handle down on the charging station, of course the shutter opens because there's a strange force on the planet called gravity. So the flap only closes when you carry it from one job to another. Typical B&D design of the 1970s. This company really needs to find industrial designers.
