Well washed everything that needed as I have 4 collies so plenty hair to clear up.I have not gone into main body,Last week I was doing the stair carpet,a very lengthy job and it did shut off,I thought it was a fuse,checked that,ok.My husband said let it cool down and see what happens,there was no burning smell,it did start again later, so hoovered living room,put the hoover away.I have used it several days but when I went to do the stairs today,it won't start .
