A great alternative to compressed air / vacuum to clean PC's etc.,
This review is from: Metro Vacuum ED500 DataVac 500-Watt 0.75-HP Electric Duster 120 volt (Tools & Home Improvement)
For many years I have used a portable vacuum to clean out my customer's computers when I make house calls. I now have replaced that vacuum and only use the Metro DataVac Electric Duster.
This nifty electric duster is basically one of Metro's powerful vacuum motors enclosed in a small can. It comes with many attachments and outputs a very powerful and consistent stream of air. Unlike expensive air cans which become cold and loose their power after a few minutes of use, the Electric Duster blows hard as long as you need it to.
Some of the cons to using this instead of a vacuum is the fact you will need to take the PC outside to blow it out otherwise dust will go everywhere (you will not believe how much dust comes out of some of them, easily 10 times more than a normal compressed air can would blow out). It runs on standard 120v AC so you will need to have a plug available within range of the (ample) 15ft or so foot cord. If you use it continuously for more than 5 minutes or so the air and can becomes very hot but not so hot that it will burn you or cause problems for the PC. It is also VERY loud, louder than most Vacuums.
The positives vs vacuuming the PC, or using a standard compressed air can, outweigh the negatives. The risk of accidentally damaging a component or creating a static discharge when using a vacuum is higher (although I have never had this happen). A vacuum will do a good job at cleaning the PC, but the force of the air stream from the Electric Duster is very powerful and reaches cracks and crevasses to blow out dust in places I didn't even knew existed! Versus compressed air, aside from the massive savings, you also have no problem turning the Electric Duster upside down or at any angle to position it - compressed air cans will blow ice out if you turn them upside down. The Electric Duster is also much smaller and easier to carry around than my portable vacuum. Finally, the Electric Duster is environmentally friendly compared to compressed air cans or even Vacuums which you have to throw away the bags etc.
While the Electric Duster is a bit pricey for people who only need an air can every now and then, for those of you who buy a lot of compressed air, or need something a lot stronger, this is a must have replacement.
UPDATE: Almost a year later this blower is still working strong! The complaints about the black nozzle shooting off seen in other reviews were listened to by Metro and the newer versions have a button/release mechanism. I still stand behind this 5-star review!
UPDATE: Two years now, my original blower is still a strong as day one. I now own two more just for convenience, I keep one in the car for on site work, one at the office, the other at home! The price seems to vary greatly, so look around and you may catch it on sale!
UPDATE: I have added a video of me blowing out dust from two computers. This is typical of the amount of dust in a computer that has never been cleaned for a couple of years in a home that has pets. As you can see in the video, the MetroVac is VERY strong and blows out TONS of dust. It gets in cracks and crevasses that a normal air can wouldn't come close to blowing out, and you don't have to worry about moisture that can be blown out of other compressed air alternatives.
IMPORTANT NOTE: There is another listing for this product on Amazon: Metro Vacuum ED500P DataVac 500-Watt, .75-HP Electric Duster. This is the same as this listing, it is NOT a different version as the description there states! Don't get fooled, it is much less expensive at this listing!
4 YEAR UPDATE!
Its been four years and I now own three Metro Dusters for convenience of leaving them at home, office and car. Even the oldest of my Dusters, one of the first generation ones without the nozzle attachment button, is still going strong! A great product!

If you have a big stand-up fan or even an eight-inch box fan, maybe you can position the fan so it blows away the dust you stir up with this vacuum/blower. Then the dust can settle to where you can use a foxtail and dustpan, and you won't need to disconnect your PC and take it outside. I am going to buy the Metro.

I liked the product, sorry it sounded like an ad. As far as taking the computer outside, you don't have to but 95% of the time you will have wished you did! Computers are like air purifiers without filters, sucking in air and dust all the time they are in.
I stand behind my review, and I still use this way more than a vacuum as it does a MUCH better job at getting dust out of the cracks in the machines.
Its dropped in price too, I see it for $30 at Fry's these days.

Why not set up your vacuum clean (tube kind) while using the blower? That way most of the dust will get sucked up by the vacuum. That's what I do and it beats having the dust go all around the room. I set up a bright light and can see most of the dust going into the vacuum.

Really good, thorough review. Was looking for a good alternative to compressed air cans (3 computers here at home).
Never EVER apologize to a troll. Ignore them and they go away.

Great review! I go through a lot of compressed air and you sold me on this item.

I'm looking at purchasing this blower as a back-saver - I end up dragging computers to the basement to blow them out, or dragging the air compressor upstairs (heavy!) - but I'm a little concerned about the lack of pressure control. Is there any way to reduce the pressure if needed, for more delicate work? Also, is the power switch momentary or latching on-off? Thanks for the great review!

Re the edited comment, "The complaints about the black nozzle shooting off seen in other reviews were listened to by Metro and the newer versions have a button/release mechanism."
When looking to buy this online, how can you tell if the product being offered for sale is the new version with this new button/release mechanism feature when it isn't mentioned in the specifications? Is there an obvious difference in the model number (should be imo) or can one tell by looking at the picture of the product?

The power turns on and off with a toggle button that you push in and it clicks on and off. There is a bit of torque caused when you turn it on, you will want to have a hold of it or if it is sitting on the ground it will likely start spinning around on the floor and could knock something over.
You can control the volume of air (thus changing the pressure) with the various attachments, but the motor runs at full on or off setting. That would possibly be a nice feature for a future model, but I have never had the issue of needed a lower setting. I now own three of these. One at home, one in the car for on site work and one at the shop bench.

The last two I have bought have been the new model, I think all but the very early ones have the clip so unless there is some very old products on selves somewhere I would think anyone you get now should be the new model. Perhaps MetroVac can better answer that question however.
