I purchased a steam cleaner on the internet. When it arrived I plugged it in and turned it on, the steam that came out was pathetic and so I decided to return it to the supplier (thinking I was protected under distance selling regulations). The company phoned me offering other steam cleaners but as I wanted a 2in1 model (which they didn't have) I asked for a refund and that was when my troubles began - they are now saying because of hygiene rules they cannot take it back. They say that I could have taken it out of the box to inspect but not turn it on (although they were quite happy for computers/cameras to go back as long as nothing had been installed on it). Is this right? I purposefully did not put on any of the pads/tools I just filled the tank with water and turned the machine on and it was quickly evident that it was unlikely to clean anything. Does this invalidate the regulations?
