DeWalt 18/20V MAX Cordless/Corded Wet-Dry Vacuum


The DeWalt Cordless/Corded Wet-Dry Vacuum model DCV581H uses a DeWalt 18 or 20 volt battery or the cord for powering the handy portable vacuum.

Recommendation: 4/5

The DeWalt 18/20V Wet-Dry Vacuum is a handheld corded or cordless vacuum but you do need to purchase a battery for cordless operation. The DeWalt DCV581H comes with the vacuum, hose, two attachments, filter assembly and manual but is not sold with a battery or charger.

The DeWalt DCV581H uses a decently powered motor to provide suction and has the really nice feature of being able to use either batteries or 120 volt wall power. The DCV581H can use either 18 volt or 20 volt DeWalt batteries with the 18 volt being either NiCad or lithium ion battery.

The 20 volt MAX batteries are only lithium ion so are a bit more expensive with batteries starting at about $90 for a pair of the 18 volt NiCad. I did not receive a battery or charger with the vacuum so I am not reviewing the power of the vacuum using a battery.

I checked out the functions and features of the DeWalt portable vacuum using the 120 volt corded operation and found the vacuum works very well. The ball on the inside of the tank prevents water or liquids from getting into the motor so you do need to hold the body of the vacuum somewhat level when using.

The DeWalt DCV581H has a five foot hose that attaches to both the intake and exhaust ports for both vacuum and blower use and is a common 1 1/4 inch size. The DCV581H comes with a crevice and wide nozzle tool but you can buy other tools in this common 1 1/4 inch size at stores like Menards, Home Depot and Lowes.

The DeWalt vacuum has the removable filter that can be washed for easy cleaning while a new filter will cost about $25 which is pretty common for these types of filters. The filter does a great job of keeping dust and fine particles out of the motor but you can buy new ones when it gets beyond the point of using.

The DeWalt vacuum has enough power to pick up wood chips, sawdust and other smaller debris but balks at things like bolts and larger nuts. I had no problem getting up hair and dirt from a spilled plant but could not get up some of the rocks also in the plant.

The DeWalt vacuum has enough power for shop jobs like broken pieces of glass or sawdust which is what it’s made for but for larger jobs like rocks or pieces of concrete you may need to step up to a more powerful vacuum. The DeWalt vacuum does a great job around the house and in the shop for lightweight work just like my other handheld vacuums from DeWalt and Milwaukee in this same category.

The vacuum does a great job for dust bunnies and hair around the house and with its battery operation would make a great home vacuum for quick cleanups. The tank is easy to empty using the two side latches and the plastic makes it easy to wash and scrub out when really dirty.

The tank can be washed out with soapy water if you get it dirty with more than simple dirt or liquids which is a common use for a wet-dry vacuum. You can vacuum up water or other liquids but you should clean out the tank immediately to prevent the tank from getting rank or funky.

The filter also needs washing after cleaning up liquids but the fiber material used in the tank is pretty tough and can take repeated washing and vacuuming up liquids. After cleaning up liquids and rinsing or washing the filter you should let the filter and rest of the tank dry completely before reassembling the vacuum.

I really enjoy using a cordless vacuum for quick cleanups around the house and when I work on projects for a quick and easy way to keep things tidy. I was a bit disappointed when I did not receive a battery but the DeWalt vacuum works really well even when using it with a cord.

The DeWalt Wet-Dry vacuum worked well while I was trying it out for a new project building a kitchen countertop and for odds jobs all around the house. I highly recommend the DeWalt vacuum for a great corded and cordless vacuum that gives you the versatility of deciding how it’s powered.
