This is the DC (cordless only) version of DeWalt's new vac. Like the AC/DC (corded and cordless) model it can be powered by post style (XRP) battery packs and the newer (20V MAX) slide mount packs. The batteries fit into a recessed area on the side of the machine.
The vacuum in the foreground is the AC/DC model; the one in back is cordless only. Note the cord wrap on the AC/DC model and how neatly the hose stores on the machine. A crevice tool stores in the handle and a wider nozzle on the side of the housing.
As with most vacuums, the lower part of the machine is a simple tank. The interesting parts are in the upper housing. Here you can see the filter, which on the AC/DC model is HEPA.
The right side of the radio has a compartment that will hold a smart phone or MP3 player. The device can be connected to the auxiliary port and played through the speakers and connected to the USB port (see left side of compartment about half way down) for charging when the radio is plugged in. There are two 10-amp electrical receptacles on the other side of the radio.
The DCR015 accepts 12V and 20V MAX batteries, which fit into a compartment on the back of the housing. The radio can charge the battery or be powered by it (when not plugged in).
The scanner uses ground penetrating radar technology to locate components inside of walls. It works to a depth of up to 3 inches on a variety of wall surfaces including drywall, plywood, concrete, marble and ceramic tile.
One of the unique features of this tool is the graphic display, which displays a visual representation of what is inside the wall. Here it's showing a stud - not the actual stud but a representation of the wood that it senses behind the drywall.
