Review on 🧹 Compact Lithium BLACK+DECKER HNV215B10: Powerful and Portable Cleaning Solution by Anthony Grover

Very bad suction! It's just that a small amount of dirt quickly clogs the vacuum hole due to a design flaw: there's a damper meant to act as a one-way valve to prevent dirt from falling back out of the vacuum, which only manages to create a hallway where the dirt sits until you turn it upside down to open the valve and move it further into the canister. You need to stand upside down frequently or immediately after vacuuming up a tiny handful of dirt. The power button must be kept pressed during cleaning, otherwise the motor will stop. That means you're pulling it all the time, like a trigger! The battery only lasts 5 minutes before the suction power becomes too weak to count.
