urgent advice on best carpet cleaner to get please!!!

[momof2boys]

i need a carpet cleaner to clean my carpets. I have a bissel pro heat and i am fed up of it breaking down so need a different one.
I am a childminder so as you can imagine my carpet gets dirty VERY quickly with god knows what being spilt on it so i need something that i can use either weekly or monthly.

I have looked at the vax ones but it is just blowing my mind as to which one to get. I need one that gets all the dirt out ( got beige carpet) and that dries quiclky.
thanks in advance

I have very light carpets, a 12 month old labrador and a dd with all her pre teen mates and ds with severe ASD. I wash my carpets about once a fortnight and have a vax all terrain. We bought this rather than the rug doctor because it had a 5 yr guarentee and our previous cleaners seemed to have a habit of breaking down after 12 months and 1 day!

Having the heating element makes a huge difference; the carpet is dry in no time. The heat is only used on main cleaner rather than attachments and when I clean the stairs they take much longer to dry so this still tends to be on a day I will be out the house.

Hope this helps
