Rated 3 out of 5 by from Acceptable but ... The wetvac has about the power / suction expected for a 3 Gallon size but the flip-up panel that protects the battery does not stay shut. It's cheaply executed. The method for emptying the debris is a bit difficult. It does what I bought it for. The registration process is absolutely awful. Ridgid really needs to straighten this out and make registration for ALL its products simple and located on a single webpage. The webpage would never recognize the product number. The model / product number on the box and on the device are different. Very confusing, and even more so with the website not recognizing ANY of the product numbers. I had to call Ridgid (India) and suffer someone who could not be very helpful. This individual directed me to a completely different registration website from the one printed on the product box! Painful

Rated 4 out of 5 by from Good, but... Compact design and powerful motor make this a worthy addition to my Ridgid 18 Volt Tool Collection. The battery gets sucked dry fairly quickly, but planning ahead, I just make certain I have plenty of batteries on-hand so I don’t run out of power. There’s no dedicated storage space for the hose. I little tweaking to the case design in the future might be able to remedy that “design flaw.” Overall, a nice addition to my Ridgid Tool Collection!

Rated 5 out of 5 by from Except for the hole provided to hang it up, this is a very good product. Overall, excellent, but you need to come up with a better way to mount to the wall.

Rated 5 out of 5 by from Works as it should. Great vac. Just as powerful as my corded vacuums. It really sucks!

Rated 5 out of 5 by from Convienent and powerful, no dragging a cord around I wasn't sure how this vac would perform. But, after using it for a week I am very impressed with how well it does the job. It's so nice to just grab the vac and head for my truck to clean out the cab; no searching for an extension cord and an outlet. The vac has much more power than I anticipated. I rated the durability as excellent, but I have not had the unit long enough to say with certainty. Well worth the money.

Will the hose fit into the exhaust side to use as a blower as well?

Low battery ?

I just purchased this vacum . I own 4 Ridgid 18volt Lithium batteries. 3, 2.0 AmH and one 4.0 AmH . I tried the 4.0 one first and after exactly 5 minutes ( not complaining at all about run time ) it started to go on and off . I figured if it was dying it would get weak then just shut off. I then tried a 2.0 AmH battery and after a while ( I didn't time this one) it gradually got weaker lower and gradually shut off. So is this normal for the vacum ? I called Ridgid they said they didn't know if the batteries could do that and recommended I return. Thank you for any help .
Asked by: CabinetGuy1981
Sounds like the vac has a problem. Maybe the battery was loose or pop loose. Because I can run mine on a 2.0 fully charged battery for over 10 mins easy. Yes as the battery gets close to running out of power it doses slow down just a bit and then it just shuts off completely. But it doesn't turn off then back on again that sounds like a connections issue to me. Maybe a wire is loose on the inside some ware from the factory. I would just go with what Ridgid Customer Service said and return for a new one.

Is the 18v cordless vac eligible for the Lifetime Service Agreement?

I recently purchased the cordless vac, and it very clearly states LSA eligible on the box. I am familiar with registering products for the LSA, and all of my other tools, once registered, show the warranty status. However once I registered the vac, (which incidentally required a separate login), there was no mention of the LSA. Please clarify.
Asked by: Derrick
No. This vacuum is registered thru not RIGID Power Tools which has the LSA. However, warrants the vac for lifetime. I assume it is the same warranty that covers their other shop vacs. Hope this helps.
