DeWalt makes one model of cordless-only handheld vacuum, which is offered both with and without a battery. The battery is interchangeable with the huge line of DeWalt tools, so if you already own DeWalt power tools such as a cordless drill you can save on cost and get it without a battery.
They also offer a model which can operate either plugged in to a 120V outlet or with DeWalt 12V or 18V batteries.
These hand vacs are part of the limited number of wet/dry cordless options out there. If you’re looking for the most heavy-duty hand vac available and need the portability of a cordless, DeWalt is a great choice.
