I was hoping this vacuum would stand up to my shopwack nozzles as it has a round nozzle (oval ones only fit itself). In fact, the outside diameter of the nozzle is only about 1-1/4 inch and the inside diameter is just over an inch. (Tip: an adapter would be very useful). It's more comfortable to hold in hand than wand style car vacuums and I love that it has an actual crevice tool and brush rather than a combination tool that can't handle both. Impressively good suction The charging cable is a bullet connector, which isn't that uncommon for cleaning devices, but the other end is USB, which is the worst of both worlds. The charge level indicator is on the USB connector, which is a cool innovation, but still far from a perfect user interface.
