Hi guys... new to the board... but lets just get this going...
My opinion after many years in the industry is that I would NEVER run a slide in for MANY reasons.
1. Heat inside van
2. smell inside van
3. Slide-ins (for me) always have something leaking. I'm a cleaner, I hate messes! Though I know many cleaners who really don't know what clean is. Just look inside their vans. GROSS!!
4. Harder to work on. Two engines to deal with and many more parts to fix.
5. More maintenance period.
For Direct Drives, I don't have to deal with any of that malarkey. I own a reliable Ford V10 and rarely have any issues. Just works. The set-up is much nicer where-as with a slide in, you're lucky to get the unit in the side door. I have the unit and all the hose reels out the side door and not to mention a small chemical shelf TOO!!
I went Direct Drive back in 1996 and never looked back and never will. Yes they cost a little more in gas but you know what?... I'll pay the extra gas to NOT have all the other problems associated with a slide-in.
And the issue about utilizing the van's engine is bogus! The vehicles engine will WAY out-last any tractor motor, any day. And I am sure their are exceptions, though I personally have never replaced a van engine. I buy new every 5 years. One thing I do that most guys running DD don't, is I open the engine hood on every job. This decreases the engine heat. Some say this looks terrible, but I say it looks Great! Because the customer will ask why do I have the engine hood open and I will tell them that my system runs of the van engine and has the most power, where most other cleaners run a small tractor motor with little to no power.
Also, I will say that anyone thinking that a slide in has more power than a direct drive is very ignorant and most likely knows nothing about a DD, even though they may lie through their teeth and say they do. I know many cleaners who would make better attorneys than cleaners! Such good liars!
My opinion on brands:
HydraMaster: Yes, they have distributors everywhere which is a definite plus if you are not mechanically inclined. But for the two units I owned, I had way more problems with
HydraMaster than I care to deal with. I will say that
Butler for me, has been the absolute most reliable. So for the few repairs I find myself doing, it's no big deal to have to become a part-time mechanic. But this is VERY part time as I rarely have any problems. My
Butler is older and so I recently bought a White Magic... I had MANY problems with this machine for the first 200 hours, but after all the bugs have been worked out, the machine is running like it should.
I'm not really a fan of Cleanco because they believe in cfm's over lift. I believe in a balance of both cfm's and inches of mercury. Cleanco offers only 10 inches of mercury (lift) and I think that is ridiculous! Yes air-flow moves water, but with out enough lift, what's really going to move that volume of air through your hose?? It boggs down very easily, especially with their Quad 56.
On the other hand, White Magics Pro1200HV system offers 20 inches of lift which is double that of Cleanco and my carpets dry within two hours max!
Butler has very good vacuum for a 47 blower... probably the best around.
Their system which is called the 5.8 is really a 47 blower (for those of you that didn't know).
Prochems new Direct Drive is simply a Cleanco unit made for
Prochem.
The only other PTO I would consider is an
AeroTech. But for me, I don't have a place to park it and it is too big to do the things I need to do at this time. I don't want to have to rent a place to park it. Too Much.
If
Butler would get a bigger blower into their big trucks, maybe I would consider one those in the future. They have a nice little 12 foot box. Good enough for me. But I want at least a 56 blower. Carpet simply dries faster even if you are only a single wand'er.
I hope this can help in your endeavor! Good luck.
