This brush suits hard floors. So if you have mainly lino, wood, stone or tiled floors rather than carpet then this brush suits you better than the pedal tool that comes with Henry as standard. (The pedal tool has a metal plate underneath which is designed to rub on the carpet - this obviously does not suit hard floors). The castellated brush on the front knocks up the dust ready to be sucked away & the straight brush on the back leaves a clean sweep. This brush has a 32mm fitting which suits Henry & all his brothers & sisters!
