Electric

— this category includes all manicure sets that include a machine with an electric motor and nozzles for it. Also, the package may include hand tools, as in instrument kits (see the relevant paragraph), but this is not necessary. Electric machines are well suited for labor-intensive operations such as grinding or polishing; in addition, universal solutions for manicure / pedicure are more common among such sets. Their main disadvantage can be called dependence on power: in the absence of a network or a dead battery / battery, most of the features (or even all) are not available.
