DEWALT DCV581H 18/20-Volt MAX Cordless/Corded Wet-Dry Vacuum is very versatile, industrial grade and quality vacuum cleaner. It can be operated corded or cordless, it can pick dry and wet debris and to protect air that user breathe and to protect motor, it features washable, HEPA grade filter.
DeWalt DCV581H has features that are rather uncommon for 'ordinary' home cordless vacuums.
First of all, it is not the lightest vacuum cleaner - it weighs around 9.1 pounds (around 4.1 kg) and when in use, it is held by one hand (or it is on the floor), while other hand cleans the area with cleaning hose. However, it is very sturdy and durable unit - casing is much stronger than casing of many other, larger and more expensive vacuums.
Unit dimensions: 17.2x12.3x13.1 inches - 44x31x33 cm.
Unit can operate corded using an AC outlet, or cordless using an 18V or 20V MAX battery or even older DeWalt 18V XRP NiCd batteries.
DCV581H vacuum is equipped with HEPA rated filter which traps up to 99.97% of small particles that would otherwise be released back in the cleaned area - if the filter can cope with construction sites' dirt and debris and clean the air efficiently, it can clean home dirt and debris easily.
HEPA filter is not cheap, but it is washable and reusable - when cleaning it, be very careful not to damage it. Use plenty of water to gently flush the dirt out. If you use compress air to clean it, don't use more than 50 psi (~3.5 atm), otherwise you could easily damage protective membranes, making the filter useless.
Vacuum has crush-resistant, 5 feet (~1.5 m) long and 1.25 inch (3.2 cm) diameter hose. At first look, hose could be longer, but in most situations, vacuum is held in one hand and hose in another, making 5 feet hose more than long enough. Vacuum can operate as blower, too, providing 33 CFM (cubic feet per minute).
DeWalt DCV581H comes with a crevice tool and a wide nozzle cleaning tool.
Dirt bin capacity is 2 gallons (~7.5 liters).
Very important note: Battery and charger are sold separately. Again, this is industrial grade vacuum cleaner and DeWalt, as manufacturer, sells many cordless tools (cordless drills, for example) which use standard size DeWalt's batteries. So, if you already have DeWalt's 20V MAX lithium ion battery and charger, DeWalt DCV581H vacuum cleaner will actually come very cheap. However, if you don't already have these batteries and chargers, and you don't need industry grade vacuum cleaner, for money required for DeWalt DCV581H AND the battery AND the charger, you should check first excellent Dyson V6 cordless vacuum cleaner - Dyson V6 comes in many versions with various cleaning attachments suitable for home use.
If you do need this type of a vacuum cleaner, having batteries and chargers or not, consider DeWalt DCV581H - it is robust, durable, corded or cordless, can pick dry and wet debris, has good suction and excellent air filtration.

DeWalt Wet/Dry Vacuum Replacement Filter
This is the original DeWalt wet and dry vacuum cleaner replacement filter. It fits DCV580 and DCV581H vacuums. As said before, it is HEPA grade air filter which traps 99.97% of particles as small as 0.3 microns. It is washable and reusable filter, but when washing and cleaning it, be careful and gentle, since membranes are rather delicate.
Non-oems filters are cheaper, but personally, not recommended.

DeWalt DCB204 20V Max Premium XR Li-Ion Battery
These DeWalt batteries are compatible with the entire line of DeWalt 20V MAX Tools and can be used by DeWalt DCV581H vacuum cleaner.
They are rated at 4 Ah and can provide plenty of power, for long period of time - almost long enough for one battery to fully charge, while other is constantly in use in the vacuum itself.
Batteries have the 3-LED indicator system which gives immediate feedback on the state of their charge level. Being lithium ion batteries, they feature practically no memory effect and almost no self-discharge.
Individual packs weigh around 1.42 lbs (~0.64 kg), adding to the weight of the vacuum cleaner.

DeWalt DCB205 20V MAX XR 5.0Ah Lithium Ion Battery
These batteries are very similar to DCB204 batteries, except that they have even larger capacity - 5 Ah. These lithium batteries can be fully charged, while vacuum cleaner is in full use, using another battery.
However, they cost more.
These batteries also have the 3-LED indicator system which gives immediate feedback on the state of their charge level. They also practically have no memory effect and almost no self-discharge.
For more reviews and recommendations, feel free to follow DeWalt DCB205-2 20V MAX XR 5.0Ah Lithium Ion Battery, 2-Pack Amazon link (link opens in the new window).
Note that DCB204 and DCB205 are high-end lithium batteries and they are designed to power much stronger cordless tools. If you don't require 4 or 5 Ah batteries, there are similar batteries with lower capacity, that are also cheaper, but provide shorter cordless operating time.
And few cons about DeWalt DC581H ...
DeWalt DC581H is good vacuum cleaner in its class that comes at great price. However, there are things that could be better. Perhaps they will be rectified in subsequent sub-models of DCV581H, but at the moment of writing this review, they are not.
The battery compartment is rather exposed, which is not the best idea for wet/dry vacuum. However, although rated for wet/dry dirt, it is not designed for use in the rainy conditions! But, protection of battery compartment could be better.
There is no way to attach a shoulder strap - this is very important since one needs both hands to carry vacuum around and to use the hose. Imagine yourself on the ladder, vacuuming something using this vacuum - not recommended activity :)
Also, there are no transport wheels. DCV581H is not heavy unit, but shoulder strap and transport wheels are not rocket science and their addition would not increase the price, nor make things weaker or more complicated.
Top of the vacuum is not a flat - handle is not retractable. This way, nothing can be stored or positioned on the vacuum (not even a handful of papers, for example). Also, exposed handle is easier to get hit with some other tool or foot and get damaged.
Power cord could be longer - 1.5 feet (~1.5m) power cord (hose is also 5 feet long) is simply too short, except for connecting to extension cord. Even for that, it is sometimes too short.
Long story short - DeWalt DCV581H is very useful vacuum cleaner with many pros and few cons that one must be aware of.

Note: if you need similar device in this price range for home use, consider corded Shark Rocket 3xx vacuums or cordless Dyson V6 vacuums before DeWalt DCV581H - I really respect DeWalt tools and DCV561H is excellent vacuum cleaner for construction sites or workshops, but for home use, there are simply better vacuums out there...
