The 'hoover' sound came from the Roland Alpha Juno 2 and became a signature of Belgian techno and hard dance

The hoover is a harsh, sweeping, vacuum-cleaner-like sound produced by the Roland Alpha Juno 2 synthesizer. Belgian techno producers in the early 1990s adopted it as a darker alternative to Detroit techno’s soulfulness, and it became a cornerstone of NRG, hard house and hard trance. The name derives from its sonic resemblance to a vacuum cleaner (a ‘hoover’ in British English). The article attributes the sound specifically to the Alpha Juno 2; the classic patch is a detuned, resonant, sweeping tone, which is why modern producers reproduce it with heavy detuning plus a resonant filter sweep or simply sample the original preset.

Examples

Belgian techno and UK hard house records built on the Alpha Juno 2 hoover. Modern producers reproduce it with a detuned saw layer under a resonant filter sweep, or sample the classic preset directly.

Assessment

Name the synthesizer that produced the original hoover sound and explain why the sound was nicknamed a ‘hoover’.
