Here's a revised description of each Eeveelution with characteristics of machines that align with their respective types:

1. Vaporeon (Water-Type): Vaporeon now embodies the characteristics of a water-cleaning robot. It has water filtration systems integrated into its body, hydrodynamic fins for efficient swimming, and high-pressure water cannons for offensive attacks.

2. Jolteon (Electric-Type): Jolteon takes on the appearance of an electrical generator. It has electrically charged capacitors on its back, conductive plates along its fur, and lightning rod-like appendages that absorb and discharge electricity.

3. Flareon (Fire-Type): Flareon transforms into a mechanical furnace. Its body is encased in heat-resistant alloys, and it possesses powerful flamethrowers, exhaust vents, and temperature control systems that allow it to generate intense heat and flames.

4. Espeon (Psychic-Type): Espeon adopts the form of a psychic amplifier. It has intricate neural circuitry on its body, crystal-like receptors that enhance psychic abilities, and antennae that amplify and transmit psychic energy.

5. Umbreon (Dark-Type): Umbreon now resembles a stealth reconnaissance drone. It has sleek, dark-colored armor for camouflage, night vision sensors, and retractable blades for precision strikes. It also features advanced scanning and surveillance capabilities.

6. Leafeon (Grass-Type): Leafeon takes on the appearance of a mobile photosynthesis unit. It has solar panels on its back to harness sunlight, nutrient storage compartments, and extendable vine-like appendages that aid in absorbing nutrients from the environment.

7. Glaceon (Ice-Type): Glaceon transforms into an ice-making and freezing machine. It has built-in cryogenic systems, ice crystal generators, and refrigeration units that allow it to produce and manipulate ice with precision.

8. Sylveon (Fairy-Type): Sylveon now resembles an enchanting music box. It has delicate, intricate gears and mechanisms, melodious chimes that emit soothing sounds, and ribbons that contain magical properties to enhance its fairy abilities.

In this alternate version, the Eeveelutions embody the characteristics of machines that match their elemental types. They showcase mechanical features and functionalities that complement their respective abilities, creating a unique blend of nature and technology in their designs.
