Throw out wildly expensive hoover. Go to local hardware shop. Spend £2 on a rubber squeegee for cleaning windows. Put kettle on. Use squeegee to brush hair out of carpet quickly and easily. Drink tea and admire revitalised carpet.
Cannot believe how disproportionately happy this thread has made me - my bedroom carpet is revolting due to fluffy cat and my post pregnancy moulting. Before I skip to the shop; a squeegee is the flat plastic blade thing isn't it? And is the wilko one a rubber bristled brush? Thankyou!
