I saw something similar in PnP this weekend. It was in the isle with all the headphones. Just be carefull with the load. Check how much watt your vacuum cleaner uses and check the load capacity on the plug before you buy it.
I'll check next time I'm at PnP (probably today). The vacuum is 1800W and the saw is 1300W so I'm a bit over if it's 13A and I need to count both, but well clear if I only count the vacuum.
