Sounds like a power on sound. Made from a beep with a sine waveform (the hz of which increases), and bitcrushing it at 4 bits per sample and a sample rate of 40khz.

Extended version of my previous sound, power_on. Wav. This one uses a bigger part of the original sound than power_on. Wav.

Potable hoover (vacuum as known in the states) powered-on. Portable vacuum cleaner turned on. Short sample which can be looped. Two samples are included, the first is about 30cm away from the microphone and the second is a close-up to the microphone. I would advice using the end of the audio file to apply noise removal however have left this upload of the sound unedited so you can tweak this yourself to find what fits your project best. Noise removal may not be necessary at all depending on how you incorporate the sound. Also to be fair, how do you add noise removal to what is essentially glorified white noise?.
