Where is the filter on my Hoover Saver 1200 and how do I get to it?

I have just washed my dog's bed/mat in my Hoover Saver 1200 and it will not spin properly! I think I have clogged the filter with dog hairs! Can anybody tell me where the filter is (it does not appear to be anywhere at the front) and how I clean it. Thanks
