So this might sound like a dumb question. I have been using a small wet/dry vac and looking to upgrade to a bigger more powerfull one that will have enough suction power to do the job. I am looking at a 12 gallon, Vacmaster 5.5hp vac that I can get at a great price (along with a 20' hose) and my question is the following:
Will I lose at lot of sucking power by running a 20 foot hose?
My current vac has a 7 foot hose and since wifey is the one who uses the vac, I would like to run a longer hose to make it easier for her. Please advise

Thanks,
Ed
 
been too long since engineering classes, and I'm sure there's a point of diminishing returns but as long as you have a good seal I dont see why a longer hose would signiricantly reduce airlow. Even pulling water at that distance wouldn't have a dramatic effect unless you were pulling vertically and introducing head. And air doesn't work like that, so I guess the only thing that would decrease your flow is the increased surface area of the extra hose length that you're pulling the air across which introduces friction. But again should not be enough for you to notice.

-disclaimer my ass is not a practicing aerospace engineer, but i do have a bs in environmental engineering lol.
 
I went from 7’ to 13’, and even when combined together to make 20’ there still isn’t a drop in either sucking or blowing power.

20’ of hose vacuums the same exact way as it does using only 7’ hose.

Is that two hoses combined or a single hose?

basically you're looking for velocity, so at those lengths you're not changing anything. Where you will see a change is if you changed the diameter of the hose. You're still sucking the same cfm, but over a wider space, so your velocity slows. And you really do want velocity for vacuuming.

That’s 2 hoses combined.

If I ever need extreme reach [like when you have to vacuum the interior of a large boat or RV] I can stretch it even further and connect my 10’ orange hose to that for a total of 30’ hose.
 
They do sell 20’ hoses though... I went with 13’ because as you can see, 20’ hose is a bit much for everyday use while 7’ just isn’t quite enough sometimes. Especially when the vacuum itself is as large as it is... Used to drive me nuts having to pick up and move the vacuum around vehicles.

Thanks! I believe I have an extra 7 foot section laying around but if not I found the 20ft and 13ft at my local HD via online order.

Anybody that is using math to answer this question, let me save you some time. For the first year, I ran those $200 Shop Vacs permanently mounted in the trailer with a 50' length of pool vac hose. No problem at all. The problem is, under our workload, those vacs are only good for a few months before you burn up the motor. We recently purchased a Vacumaid Pro which comes with a 50' hose that seems to be the equivalent of pool hose. Again, no problems. That vac will suck pet hair out of the carpet, pennies from the sides of the seats. There's nothing I can't suck up with it, so the long answers is no, hose length doesn't mean anything with a decent vacuum.
