DEWALT 18/20V Max Vacuum, Wet/Dry (DCV581H)

Buenas potencia. Utilizo una batería de 12 amp flexvolt y no me hace falta otra cosa.

Love this vac. Works well and very portable. Use it on my car and take it crevicing for gold.

In consideration that some have found the suction performance of this vacuum limited, I hesitated from buying this vacuum for over a year hoping that DeWalt would bring out a newer version that has more power. I'm passionate about DeWalt tools and I have allot of 20V-Max tools and batteries so despite the reviews presented herein, when my old 5 gal shop vacuum started to "grind to a halt" I decided to throw caution to the wind and buy it. To be clear, this is NOT a "shop vacuum" and to compare with one would be unfair. Suction power from even a cheap 5 gal conventional vacuum lays waste to this unit. Even small corded shop vacuums use 5 A motors and this one has a 2.6 A motor (based on the label) so it has half the power. The suction is good and usable but not truly powerful. If you have a big mess to clean up, need to root-out hairs from a carpet, or you want to clean your car or truck get something else. Also, like cheap vacuums (all types), the suction air that passes through the fan also cools the motor so don't use this for cleaning up fine dust like drywall/concrete/talc/flour/rock, etc. Used this way, the filter will plug up in short order and will burn out the motor so if you have to tackle this get something else. Below are the merits of this unit and the rationale I have for scoring five stars: 1. Construction quality - Well built as evidenced by a neoprene rubber gasket sealing the bottom to the top. This optimizes suction and prevents leaks if collecting water. The on/off switch "clacks" with authority just like the side clamps for the bottom. Feels consistent with DeWalt quality. 2. Versatility - Go cordless or corded when the battery goes flat. The unit switches almost seamlessly between battery or 120V. Note however, while on 120 V, there is a noticeable loss of power. I don't know exactly why but I suspect that there is just one 18V DC motor that gets power from either the battery directly or through a AC/DC rectifier where there may be some power losses in that circuitry on its way to the motor. Works with standard 1 1/4 in vacuum hose attachments and can be used as a blower (for small jobs). 3. Wet or dry applications - This unit does either and when filled with water, a ball shuts off the air flow to the fan. The owner's manual recommends that the filter remain in place at all times, even when vacuuming water as it is made of plastic. The filter is fine enough to use as a backup to a cannister or upright vacuum for cleanup of ordinary house dust so it won't recirculate this dust and can be washed easily. You can't do that with a shop vacuum unless a paper filter and bag are installed. 4. Capacity - With 2 gal capacity and a micro-screen filter cartridge, this vacuum makes a better choice than a hand-held vacuum as it has more suction power so even with a 2 A-Hr battery, there's enough time and power to clean up lint, dust and crumbs under the whole couch or fridge. You can even take this camping with you in case you need to clean up sand from the inside the tent or RV. 5. Noise - Quiet enough to use as an alternative to a cannister vacuum if you need suction to clean out the dust from inside computers and other electronics. 6. Video Reviews - Please check out all the YouTube reviews and decide for yourself.

This thing is awesome. I would say it's slightly less powerful than a corded shop vac, but way more convenient. The only thing this hasn't been able to consistently pick up is small nails. When it does they sometimes get stuck sideways in the hose so I probably shouldn't vacuum them anyway. I was a little leery about the smaller size but it hasn't been an issue at all. My only beef with it is my beef with all wet/dry vacs, the filters get full of saw dust or whatever particulate matter is floating around and then you lose suction. This is where the vac being small comes in handy. My old corded shop vac never got more than 1/4 or so full before the filter clogged up. There was no point in taking it apart to clean the filter and then not emptying the thing, so the extra space didn't really matter. Depending on how much dust is around this thing gets 1/2 to 2/3 full before the filter needs to be cleared out. So the size is just right. Being able to carry it around without a cord is huge though. I use it on my car and around whatever job I'm working on. I can easily carry it around with one hand and it makes light work out of cleaning up. I wouldn't mind having a longer hose or a few other attachments for it, but I'm overall very pleased and would recommend in a heartbeat. I'm using a 60v 6ah flexvolt battery, but the battery life has also been very good from my experience. I also appreciate that it has a cord too. I have a few batteries so I only needed the cord the first day I got it before my batteries arrived. But I'm glad that in many years when dewalt changes up their batteries this will still be a useful tool.

This is the best battery vacuum I have ever seen or used. This is as powerful as my Mini-Shop Vac. As an added benefit if your battery charge drops you can plug it in. Whether on Battery or AC Power the vac seems to have the same function. I have been running mine on the same 4.0 Amp/Hr battery since I got it; I've used it for probably 15-20 Minutes and still have 3 Bars on the Battery. ** UPDATE ** I have used this vacuum for a few months now and it is still running great. The filter is simply rinsed under running water to clean it; I've sucked up all kinds of things including drywall dust and saw dust from my Dewalt sander and the quick emty and cleaning is great. The suction of this vacuum is astonishing especially given that it runs on 20V. I get well over 30 Minutes of solid vacuuming with a 3 Amp/Hr battery. While the power is not real increased by using a 120V outlet it does help with battery usage; though with over 2 dozen batteries that doesn't effect me too much. This vacuum is just so convenient because of the effectiveness and battery power. It is great being able to quickly clean up a job site that doesn't have power. I'm nearly elusively running Dewalt Max battery tools now; except for the occasional job my plug in tools are relegated to the garage and because of this vacuum that includes my Shop-Vac. Add (04/24/2016): I have added the 20 Volt Max sliding compound miter saw to my collection and while this vacuumed isn't a perfect fit a wrap or two with electrical tape makes it one. Added to the saw, to replace its horrible dust collection bag, the combination makes an almost dust free saw. Both work on batteries and allow me to bring the saw right into finished living spaces to cut. Saves time running outside and doesn't add too much bulk. I have tried the vacuum in wet mode without the filter and this thing sucks, fast, it will fill up its just over a gallon tank within 20-30 seconds. And the float ball stops the suction before too much water gets in. My only real CON with the vacuum is the worthless flat car attachment, it just hasn't worked for me. As a side note in recently redoing my kitchen pairing this vacuum with my Dewalt Palm sander made sanding the drywall another dust free job.
