Hetty (short for Henrietta) is not just a pretty face, she has all the Henry features and specification: giant TwinFlo', long life, 2-stage motors; with AutoSave - Energy Conservation - 50% Energy saving - 30% Improved Air Quality - 20% Lower Noise Level.

Every time you switch Hetty on you will automatically start on the economy setting, only if more power is needed to cope with extra dirt do you need to push the red switch to operate in Hi mode.

When you see the red light you know you are in Hi mode so when you go onto hard floors or deep carpets or don't need maximum power, push the red switch again and you are back in economy mode.
