Rated 4.7 out of 5 by 218 reviewers.
Rated 5 out of 5 by Powerful, convenient size, and ease of portability. Very happy with this vacuum. I bought this vacuum several weeks ago to use for home cleanup jobs. So far, this vacuum far exceeds my expectations. I did not need anything with large capacity. I really like the smaller size which makes navigating through the house very easy. Power is more than adequate and picks up debris quickly. Be careful not to vacuum small area rugs, the suction power will grab it. I purchased the optional bags to collect drywall dust, which was recommended by Rigid in the user manual. I did research on other vacuums, but Rigid's history and reliability helped with my decision.

Rated 5 out of 5 by best shop-vac I ever owned Best shop-vac I have ever owned. It has very powerful suction, very light and easily carried or pulled. I highly highly recommend ! April 4, 2015
Rated 5 out of 5 by Good, strong vacuum Purchased this unit to help with a reoccurring (bi-weekly) job of suctioning water out of a container. This unit has good, strong suction and operates easily and well. It has only been used a couple of times, but very pleased with it thus far. April 3, 2015
Rated 5 out of 5 by Works as designed which is excellent. I was a little skeptical about this small wet/dry vac, it's advertised 4 HP with a peak of 5.0, means little to me as I haven't a clue how they determine the HP rating, ie at 3,000 rpm ect., So I figured if the top of their line is rated at 6.5 hp the 4-5 hp should be adequate. I was pleasantly surprised at the suction power this vacuum develops. It far surpassed my expectations when cleaning & shampooing the carpet in my car. It also does the job far better than the one that it replaced which happens to be the blue/gray colored vac that's made to hang on the wall and sold at competitors store. It's well worth the $79.00. April 2, 2015
Rated 4 out of 5 by works great very compact & does the job does what you need it to do April 1, 2015
Rated 5 out of 5 by Very nice Very nice and I love all the attach and pomp ,I used for work and for my car ... Beatifull ,strong , perfect March 31, 2015
Rated 4 out of 5 by This vac is the right size for my garage and basement cleanups. I recently retired from a big box store where I saw a lot of these units sold. I put it my Christmas gift list. Wish granted. It is relatively easy to use. However, the hose is somewhat stiffer than I expected. That should loosen up with use. I would like a brush for light jobs. Also the drum clamps are a little tight for arthritic fingers. March 30, 2015
Rated 5 out of 5 by Compact and powerful Great vac. Compact size make it easy to keep in truck. It has a long hose with extension so you don't have to bend over to clean. Moves around easily while you clean with its wheels. I am a carpenter and I use it every day. March 29, 2015

Answer: 
Here are some notes from the manual:
Vacuuming Liquids:
1. When picking up small amounts of liquid the filter may be left in place,
2. When picking up large amounts of liquid we recommend that the filter be removed. If the filter is not removed it will become saturated and misting may appear in the exhaust.
Warning: do not remove the filter cage and float. The float prevents liquid from entering the impeller and damaging the motor. The cage prevents fingers from touching the impeller.
3. When the liquid in the drum reaches a predetermined level, the float mechanism will rise automatically to cut off airflow. You will know that the float has risen because vac airflow ceases and the motor noise will become higher in pitch, due to increased motor speed. When this happens, turn off the vac unplug the power cord, and empty the drum.
4. After using the vac to pick up liquids, the filter must be dried to avoid possible mildew and damage to the filter.

Thank you

Answer: 
Thank you for your interest in RIDGID!

It is encourage using a wet rug and wiping the dust accumulated on the vacuum’s power head rather than washing it directly with water as the water might enter to the motor which will be a safety issue.
