Rated 5 out of 5 by from This product a good way. Love this little vacuum. I have a larger Rigid as well but this little guy is much quieter. I have it hooked up to my dust deputy which makes a great dust collection system.

Rated 5 out of 5 by from This product is everything it says it is Found this unit very powerful, easy to move around my workshop. Easy to carry outside for my car cleaning. Easy to empty. Would definitely recommend to someone looking for value but not sacrifice power.

Rated 5 out of 5 by from May be the best low cost wet/dry vac on the market I didn't need or want a large shop vac because I don't have a lot of storage room in my work shed but I needed something I didn't have to empty after every use. It has lots of suction power and more than adequate blower power. The only draw back is there really isn't a decent way to store the power cord. The tray only allows for the two extensions and one of the nozzle attachments. That's the only reason why I gave it a Good rating for durability.

Rated 5 out of 5 by from The Vac is amazing to be so small We are in the middle of various home repairs and were using our home vac. My wife saw a construction person using this and thought be helpful for us with it being so small. I was skeptical due to the size, but I was very surprised with the suction it has to be so small. It is lightweight enough for the wife to use and powerful enough for me to use also. Great product, very happy with performance.

Rated 5 out of 5 by from Great suction in small package Due to limited space in my garage, I picked this vac out at HomeDepot. I was not disappointed. I got all the suction of a large vacuum, in a small, easy to store package. For most of my jobs, this has all the capacity I need. unable to comment on durability but with the lifetime warranty,

Rated 5 out of 5 by from Best for the money I have had 2 of them for a while, used on all kind of things. Sucking muddy water to cleaning machine shop debris. Still working fine. Retired one to only machine duty. Sucks up metal particles full of synthetic coolant and water. Still working, probably over 6 years now.Just bought new one to keep a small sandblaster evacuated. The previous other brand petered out after about 6 months. Got sand in the switch and could not turn it off. The Ridgid is working great.

Rated 5 out of 5 by from 4 Gallon Rigid Wet Dry Vac So far I am very pleased with this vacuum. It has good suction, a nice long cord, and trails behind me easily while I clean. We have other Rigid vacs at work that have proved themselves well, hopefully this one is just as good :)

Did I get a dud?

I have had this unit for a very short time with light use......partly because I cant get to suck anything. I purchased to suck up water from when my washer leaked and it picked up nothing.....also when trying to suck up dry materials. it wouldn't even pick up a penny off the floor...Am I doing something wrong? When I remove the hose the suction is very strong...but when the hose is attached the suction is very poor...
Asked by: JenniferCordova
Sounds like you've got something blocking the hose. If you attach the hose and the motor changes to a higher pitched sound you've got a blocked hose.

Seeing as there is no foam filter with this unit, will it damage the vacuum to remove the filter for vacuuming up liquid?

Asked by: Timj
Absolutely! There must be a foam filter on the unit when vacuuming up liquids to prevent debris from getting in to the impeller.

replacement / different filters

it seems like all the filters you sell are for the larger vacs, are there any filters available to purchase for this vacuum if we need to replace the stock one or want a different filter? thanks
Asked by: seracg

How often do I need to change the filter?

I have been cleaning out the ducs in my house and the one I got with the machine today already looks very dirty.
Asked by: bama97202
not sure, I use the bags for dry pick up only and the filter stays clean. You can feel the bag to see if getting full. For filter, suggest once a year if you use it to clean air ducts only...doesn't sound like you use it a lot. filters can last a long time and look like they are very dirty. You can take the filter off and tap it inside a garbage bag and run fingers over the filter to get some dirt, dust cobwebs off.

How do you clean the power head

and after removing the filler I noticed that a good amount of dust collects around the filler . I believe this happens when a bag is not used. In which I plan to do. I'm new to the product this will be my first time using it, being so Ied like to clean it thoroughly, for I'll be using inside my house.
Asked by: Donarp
Unless you are using it as a wet vac make sure to use a clean filter that is properly installed, (it's simple), and if need be wipe down the motor housing with a damp, not wet, cloth with the unit unplugged.
