Staying alive
Homecare isn’t just about keeping the place clean, and vacuuming isn’t just about plugging in and going. In this case, someone really needed to regularly check the electrics to make sure that no-one sets the house on fire.
Either the wiring needs a comprehensive overhaul, or they need to buy a new vacuum, or maybe both. As lovely as it would be to come home to a clean carpet, coming home to an unburnt house is better.
