A good cordless vacuum is a helpful addition to any household cleaning arsenal. When you don't need to worry about staying in range of an outlet, they can make it easy to clean small, out-of-the-way areas inside your home and in tighter spaces like car interiors. You also don't have to worry about a power cord getting snagged on a piece of furniture, bringing a frustrating pause to your cleaning session. Of course, a cordless vacuum can't offer the indefinite runtime of a corded option. For many, however, this trade-off is worth these appliances' near-infinite range.
