Starting tomorrow. I own several of the large, 6 HP Rigids and use them to complement my dust collectors as spot/narrow area cleaners.

I can see buying a few of these to sit right next to some stationary tools and benches for spot cleaning. They don't carry Rigid's guarantee, but I thought $25 was bad for a limited use.

I am going to get at least one tomorrow.

I learned that the unit may not be best suited for sucking up chips and doesn't have a small particular rating. I upgrade all of my vacs with a re-usable low micron filter which I am not sure this unit can accommodate (the low micron filter cost between 18 and 25 on Amazon.) just want all to know what I am not sure of. We all know it's a "cheap" unit and that Porter Cable, Rigid, etc. are not made nearly the same as the tools I bought and still own over 25 years ago.
 
I've seen videos on youtube where DIY home dust extractor systems use something similar, but they recommend 5HP or better ... I could see getting by with just a 4HP unit by making it a dedicated dust extractor or a small portable unit for use with one tool at a time, though.


Now ... how to get my grubby lil paws on a deal like this, as it would definitely be a step up for me over my vacuum cleaner...? :)

If you don't have a Costco near you, just register and log on to Costco.com and order.....the Vac will come to you!

Oh ... I do have a lowes near me .... I'll go get that one! :)

That one I could use for a main DC power unit.
 
I heard through the grape vine and now I can not confirm it so take it for what it is worth, that Home Depot may put the Ridgids on sale again as they did 2 years ago.
 
I am going to get the Lowes one and the Costco one. I like having the wheels. Thanks for the find. If HD puts the RIGID on sale. I will pick up another one of those. I don't like dragging tools around the shop.
 
I have the Stanley and craftsman versions of these vacs.....I have dedicated one to my Random Orbital Sanders (ROS).....it was a $25 or $30 special at a BORG. I also have a Delta downdraft table....no longer available, but very similar to the Shop Fox that Grizzly currently sells. http://www.grizzly.com/products/20-x-40-Benchtop-Downdraft-Table/W1733A
The vac and ROS are by far more dustless than the downdraft. I have friends that have the festool vac and ROS and have 1000.00 in the pair, I have under 150 for the rigid 6" ROS, and the vac. I also have a couple of PC 5"....which use the the same output fitting. I might recommend the Rockler coupling set with additional hose and a good fitting connector. http://www.rockler.com/dust-right-universal-small-port-hose-kit

I use several of similar powered vacs, they are handy...I have them at my DP, and OSS and Disc sander....they all dust collect well, but beyond that they are not great.....use your bigger vac for general clean up......
Just my .02

As long as one remembers that the hp rating on shop vacs has little to do with the laws of physics and lots to do with marketing tall tales.......

Read the amps

Yup, you don't know if it really sucks:smile:......or if it really sucks:frown:

The in shop trial will be the test.

Tony, How about a side by side review of both vacs when you get them?

That had to be a joke :-). I barely have the patience to photograph my pens....you've seen my photos. Now they suck. LOL

I will compare the amps though. Thanks for the reminder Ken.

Tony, your pics are fine...no issue there.

I know! We will get Dan to do a YouTube review!:biggrin:
 
Enjoy. I am going to compare the amps. I couldn't find the specs on the Porter Cable. My rigid 6 hp is 11. I will see. And enjoy, my friend.
 
So (based on the highly regarded info found here) I visited my not so close Costco today and got one. Well, not quite a single-purpose trip. LOML and I enjoy hitting there and grabbing a "free" light lunch. Needed dog food, Bounty paper towels and tp plus a few other necessities. Got it home and I must say it sucks. Quite a bit more than I expected. Going to be dedicated to the basement and cleaning up the car. Thanks for the tip!!!!
 
Can someone tell me the amps on the Porter Cable vacuum?

I can't find the specs and Costco was closed when I got there...it's only 4 miles from my house though. I did pick up the SV from Lowes though.

Thanks!
 
To your point Ken: Here's ShopVacs Disclaimer

**"Peak Horsepower" (PHP) is a term used in the wet-dry vacuum industry for consumer comparison purposes. It does not denote the operational horsepower of a wet-dry vacuum but rather the horsepower output of a motor, including the motor's inertial contribution, achieved in laboratory testing. In actual use, Shop-Vac<sup><small>®</small></sup> motors do not operate at the peak horsepower shown.
 
Listen do not even try to figure out the HP of a wet dry vac because each company will use different criteria. The larger the vac the larger the motor. Industrial vacs will have more powerful motors than what is sold in Home Centers. They use a universal motor that has shorter life than an induction motor which is found in machinery.
 
Easy ru!e of thumb is about 7.5 amps per running hp. There are lots of "ya buts" to the rule of thumb, but it is pretty good for lathes and shop vacs.

Sorts out the 3 amp motors advertised as 3/4 hp on lathes.

There are a bunch of codes and standards for honest amps, and none for hp.

Thanks Ken!

Ken, is the calculator below any good for other tools?

https://www.easycalculation.com/unit...calculator.php

And, I think the it defaults to 65% efficiency. Is that a good estimate?

Thank you.

Tony, in a perfect world. 1 HP =746watts watts = volts X amps where the problem with motors such as those come in is the efficiency and how they calculate it. When they say peak HP, what is peak HP and how do they get there?? Sucking water and sucking up dust are 2 different things. Those HP rating are for the consumer to get an idea what they are comparing to. Amps would be the more reliable number to look at for comparison but again too many other factors such as how well is the container sealed can effect ratings, what filter is used can have an effect, the size of the hose can have an effect, so it is a guessing game to a point. Just look at the container size and use that for your mind calculations.

What I highly suggest and this is my opinion, if you want facts then compare units using Consumers guide or other tests guides that are out there. They actually test side by side using the same materials. Good luck.

Thank you JT. This is excellent information. However, my question to Ken pertains to the accuracy of the website tool used to calculate hp I understand thanks to you and Ken that HP calculations for shop vac are difficult at best to calculate.

I am interested in the tool (website link) above.

Thanks again. I love to learn.

Well. I went to Costco and I prefer the construction of the. shop vac at Lowes. I can see the porter cable being a good choice for smaller shops and light use based on its size which may have nothing to do with its suction. It is 8 amps.

Tony, the web site has the formula, but the values used get into the Yea But arena.

I have seen voltage readings as small as just over 100 up to over 125. But they were not with the same meter and many/ most lower cost meters have a tolerance of 5% or so of the scale. That translates to perhaps 15 volts on a zero to 300 scale.

Label amps are better coming from a test lab.

Because HP is really a measure of work, efficiency is used to translate the volt-amps (imput watts) into the foot pounds of work. I worked with motor pump sets that were middle to high 80s for efficiency. Who knows what the efficiency of the motor is on a vacuum.



Hence rules of thumb..... You can have precision without benefit of accuracy.

I only bought the one at Lowes...the other one from Costco seemed too light and fragile for my needs.
