Vax V-2000C C87-VC-B Bagless Cylinder Vacuum Cleaner

Purchased the Vax V-2000C in the sale from Argos today (12 August 2013) for half price of £54.99. As soon as I set up the item and used it. The fuse blew. We changed the fuse three times and it tripped out the fuse box and damaged the outside transformer. I had to get an electrician at a cost which was more than the vacuum and he indicated that it was faulty and tripping out the fuse box. I have a Dyson and have never bought a Vax and just needed it for the car. It is a dangerous item and should not be sold. I shall be returning it tomorrow and I shall go to Makro and purchase a Henry vacuum for the car. He tested the fuses and they were okay, and he plugged the vacuum into five different sockets and it tripped out the fuse box.
