Thats the very Power Center my cosin had, I had the blue(of corse)7.5amp one but I liked the hose on the greyone better. Mine had the stretch hose that easily retracted when using the crevice tool and when I wasnt pay attn I would tip the vac over grr.I did like the vac for the 3 years it lasted.
And yes Panisonic did make them,I currently have the Panisonic commercial version I got 2yrs ago via ebay NOS Ive used it a handfull of times and can already smell the motor starting to burn. The motors in those suckers were not very reliable.I suppose thats why there arent many around.
