terrible brushes spread smell around room

I would not recommend this product my daughter got sick on carpet and I clean up the sick wit a bowl of water and scrubber brush I then used vax power max cleaner to freshen and dry carpet but it was useless the vax brushes made it worse and the bristle on brush smell causing the clean parts of my carpet to smell the same as the sick area so now my carpet in whole room smells musty with a hint of a smell of the sick on all areas of carpet cos the vax brushes spread it yuk
