18V ONE+™ 3 Gal. Project Wet/Dry Vacuum
18V ONE+™ 3 Gal. Project Wet/Dry Vacuum is rated 4.7 out of 5 by 243.
Rated 5 out of 5 by from Not just another "wet/dry" vac!! I bought this unit a few months ago and it has been one if the most surprisingly helpful purchases that I have ever made! I didn't realize until now how much extension cords and bulky vacs had made a "cleaner" life difficult. This unit has the perfect 3 gallon waste bin compacity for the everyday messes that I run into. The motor is surprisingly strong with a lot of vacuum power. The fact that the battery power source is interchangeable with my other power tools was one of my purchasing factors. This unit my cost more than some cheap corded wet/dry vacs, but I guarantee you, it's versatility is worth it! I included some pics of my "dirty" vac, because I USE this thing!!

Rated 5 out of 5 by from Perfect vacuum for me and my wife We needed a new small wet dry vac to replace the one I had, another 2.5 gal. It still worked but I wanted something that would be quicker to use and more convenient. Spotted this in a directtools outlet store and it was perfect. I already owned Ryobi One+ products so I had batteries. I love the fact that you are not tied down by a cord so it goes anywhere. It has saved my but a few times already with liquid cleanup. I just pick it up & its ready to go . It has a nice squared out design with the attachments always handy. My wife loves to use it to vacuum the car and quick cleanups without having to break out the big vacuum.

Rated 5 out of 5 by from About time!... I have been wanting for this vacuum for over a decade! Small, Portable, Battery Powered shop vac for small projects. Love the size, design, low weight, and portability! It is not 10000% perfect, but this form factor (size, shape, design, power) is perfect for small jobs where you don't need to unpack a gigantic vac, and just what i have needed for a long time. Easily transportable, and good battery life so far. .... Now, how about a compact multi-port charger that has a built in bluetooth speaker + radio + area light?... and a mini-reciprocating saw??... and a brushless wormdrive circular saw with a laser???

Rated 5 out of 5 by from Great Cordless Shop Vac This little vac does a nice job. Suction is surprisingly powerful, hose long enough for most jobs, attachments are just what you need. I use a 3ah battery and can power this vacuum for a solid 15-20 minutes on a full charge. I think it's perfect for cleaning out your car. Its not only portable but light as well. Have not had a chance to use the blower option. This shop vac is so good and fills my needs, I put away my corded shop vac!!!

Rated 5 out of 5 by from Awesome! I bought this tool recently, and love it. No mile long extension cord with no where to wrap it, no long hose, also with no where to wrap it. I can just pull it along behind me, with no worries. And it passed the toughest test, which is sucking all the residual water out of a toilet before removal. It has plenty if power. It does burn through power pretty quickly, but I've got 26 batteries, mostly P108, so no worries. It's totally worth it to get one. Even my clients like it. Another Contract friend of mine is going to get one, and most of his tools are dewalt.

Rated 2 out of 5 by from Good little sucker but needs design changes The size and suction of this vacuum are very good, as it makes it portable and useful for cleaning in tight spots. However, since you can’t put a dust bag inside, it clogs the filter regularly, and reduces suction considerably. The basic attachments are good but regularly fall out of the cheaply manufactured clips, which are entirely inadequate for the daily bump and grind of work. The bayonet connector for the hose has already broken off one the locking tabs, so the hose keeps pulling out with very slight effort, and the locking tab on the handle to keep it upright also snapped off within minutes, so the handle flops back down and can’t be kept vertical. Why is it that the consumer versions of tools are made so cheaply vs their professional counterparts?

Rated 4 out of 5 by from Compact I bought this as a Christmas present for myself. I have already owned several wet dry vacuum cleaners, all corded. Which are fine if you're only using them in one room, however in October I go through my whole house and vacuum out the vents. After seeing this on YouTube and checking out reviews, I knew I had to have this. It's light weight enough to drag from room to room and easy enough to use. I also should mention it's not as loud as a standard Wet/dry vacuum. I'm not planning on having to clean up 3 gallons of fluid so this is perfect for me.

Rated 5 out of 5 by from Good Vacuum - Price needs adjusting I bought the 18V ONE+™ 3 Gal. Project Wet/Dry Vacuum to replace a small traditional wet/dry vacuum that broke. At first I was unsure if I had made the right purchase. I think that the price is a bit high. But even with that in mind, I am happy with the product. The fact that you don't have to lug a large vacuum around is awesome. All you do is make sure the unit is locked in place, put in a battery and you're on your way. The suction power hasn't disappointed and the unit is very easy to carry around. Get the higher capacity lithium battery, it will make your life much better. The lower capacity batteries work fine, but a longer battery is always nice to have. Overall, get vacuum.
