Rated 5 out of 5 by from This thing sucks, really well Was about to buy a different portable vac for car when I found out about this one. Works great for short use in car , the cost of the great suction is a short battery life for the smaller battery.

Rated 5 out of 5 by from One of the best purchases ever. This vac is awesome. It makes cleanup so much easier all over, from the basement to the bedroom - dirt and dust to bugs and a bit of water, it does it all. One of my favorite tool purchases in recent memory. No regrets whatsoever.

Rated 1 out of 5 by from This unit does't support 3 gallon vacuum bags. This portable vacuum can't use the 3 gallon vacuum bags. Now this wouldn't be a problem if it were not for the fact that product web page..... lists Ridgid's 3 gallon vacuum bags (VF3501) as being a possible accessory for this vacuum. It's very misleading.

Rated 2 out of 5 by from Worked good the first couple of times I used it. Now there is no suction at all. New filter, tool filter out - still no suction. Contacted ridgid and was told to take it apart and secure the power head back to the unit. I don’t have time to pull it apart and fiddle with it. When something is wrong with an item I purchase that has “the best tool warranty around” I expect the manufacturer to simplify the process of replacing the item. Take it back, send me a new one. Sell the other one as refurbished if you want.

Rated 2 out of 5 by from Worked great the first two times, after that.... Worked great the first two times, to vacuum out my car. It had lots of suction. Just tried it, a few months later and no suction. It blows out lots of air, but no suction. Made sure battery was charged and filters were luck

Rated 5 out of 5 by from Portability and power wet or dry. 18V Cordless Wet/Dry Vacuum I have been patiently waiting for Rigid to offer such a compact and handy cordless vacuum for several years since purchasing their 18V Drill/Driver combo. In fact I liked that combo so much I purchased a second set for my summer home in New York. And needless to say, their lifetime warranty is hard to resist at their competitive price point. So as soon as I saw this vacuum was available, I ordered it from Home Depot’s web site. It arrived in a nice box, and as I learned during their on-line lifetime warranty registration process, to keep their boxes for their discrete tool item identifiers. I used one of my drill set’s 18V batteries to power the vacuum. The first time I used it was to suck about an inch of water from a clogged basement sink. It worked very quickly. When I was done, I easily removed the tank and dumped the water outside. The next day I used it to vacuum sawdust off my workbench and that worked fine as well. Then just today, I easily carried it upstairs and vacuumed the dust filters from our two window air conditioners using the included dusting brush hose attachment. I also really like the way the hose stretches and then recompresses like an accordion. So all in all, the portability and power of this handy “tote” vacuum is a real value to me. And already having the 18V batteries and charger made this purchase a no brainer.

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

Can’t change filter

I can’t get the filter nut to unscrew. Any hints?
Asked by: Jpmatx
It doesn't unscrew, the filter just pops off, instructions are in the manual.

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.
