Electric shavers are divided into two main types: rotary and foil. Rotary shavers have round heads with rotating blades, while foil shavers have a rectangular head with oscillating blades under a foil. The number of blades on rotary models is usually 3, on foil models from 1 to 4.

Shaving speed: rotary shavers provide faster shaving due to the simultaneous operation of multiple heads, especially on large areas. Foil shavers require more careful strokes but are better for sensitive skin.

Shaving quality: rotary models give a close shave but may miss long hairs; foil models are smoother, especially with daily use. Care: rotary shavers are easier to clean (often waterproof), foil shavers require careful handling of the foil.

Price: rotary shavers are generally more expensive due to complex construction, but budget options exist. Foil models are available in a wider price range.

The choice depends on personal preference: for quick shaving - rotary, for sensitive skin and smoothness - foil.
