After the disappointing performance of previous DustBusters and other portable vacuums, I was pleasantly surprised by how well Black & Decker’s 15.6V DustBuster worked. With its high-voltage motor, “cyclonic action,” and unique rotating filter, it might even serve as an alternate to your shop vacuum if you’re working in tight quarters or have very little storage space.
Two simple features seem to make the difference: First, a special design creates a “cyclonic” airpath inside the collection chamber, helping to prevent filter clogging and subsequently keeping you at full suction power longer. And unlike most portable vacuums which place a filter directly between the motor and a straight-through opening, the DustBuster 15.6V features a deflected opening, further reducing the risk of clogs.
Second, when the filter does finally clog and you notice a drop in suction, you can simply rotate the purple ring on the side of the vacuum to expose a fresh section of the filter.
With an average street price of $50, this vacuum can be found for a bit less if you shop hard. Home Depot, Linens ‘n Things, and Bed Bath & Beyond, for example, carry the non-HEPA filter version for about $40 — a lot cheaper than the Dyson Root 6.
