I bought a Vac N' Blo and because I knew it would be perfect for simple vaccuming and interior cleaning but I didnt think about moderate to heavy stain lifting and extracting. I am thinking I now need to buy a wet/dry shop vac. I am going to pick up some Folex this week at Lowes and I already have 303 spot remover and Ultima interior shampoo. On a heavily stained carpet will 303 some Folex a carpet brush and a Vac N' Blo do the trick or is a wet/dry shop vac a must? Like I said before I want to offer the most professional detail I can to future customers and I would like(if the job is possible) to make their carpets spotless. I guess the Vac N' Blo isnt what I should be using. I found a 5.5 HP 12gallon wet/dry shop vac at lowes for $80 which is a pretty good deal and it comes with a detachable blower. What do you suggest I do? And on the topic of wet/dry vacs how much HP would you guys say is nessacary to tackle any task? Thanks
