I assume by steam cleaner and prochem galaxy your after a carpet cleaner. I've got a prochem steampro with a 135 psi pump which has been very good - just a pump in 5 years (old one was 100 psi). There are better out there but I don't think you will go far wrong. Don't get the prochem heat n run they are pants - I've had three but the heater from cleansmart is very good and they also doa very good machine. I would also add a hard floor tool and a rotary and offer hard floors as well but get trained. Post this on the carpet side for other opinions
