This vacuum cleaner I inherited - great, I thought, light weight and no bags needed. However the things screams so loudly I have to stuff cotton wool into my ears, even then my ears 'sing' horribly for a while after. I have to really, really want to vacuum before I can bring myself to use it.
This thing really ought to be condemned. I really need a vacuum cleaner that doesn't damage my ears! I wonder if there is some kind of app that can measure decibels - anyone know?
