😬. I just bought the 517b... But half of what I bought it for was putting fluid systems under vaccum while I remove hoses or sensor or whatnot. No spills. I figure it should be fine for that. About to go try it on my car.
After a thurough annual cleaning of my car, I have no complaints. It sucks. It fits regular vacuum attachments. A 5ah battery did about 5/6ths of my car (this was no quickie, did every fabric/carpet surface several times). Used a brush on a drill to help get all the dirt loose from the carpet. It's a mini battery powered shop vac. It sucked as hard as I expected it to. If I needed more of a vaccum I would have bought more, it's just what I expected.
I have the cordless DeWalt 1/2 gallon wet/dry and love it! If used with water, the filter will get waterlogged and you have to dry it out but once I got that worked out, it has exceeded every expectation.
I use a Dewalt 20v cordless 2 gal vacuum, and it has been great. I use it with a bigger battery (6ah or 9ah) and it seems to last a few days per charge with light to moderate use. However, I kind of bought it on impulse, when I needed something quick for a messy job, and I do wish that I would've researched a bit. I would have still bought a dewalt 2 gal, but for a few dollars more they have a cordless/corded version.
I have the dewalt 20v hand held and love it, the tube detaches from the head and it is sooo convenient, I love it! Ive also bought into the dewalt product line so I have many batteries, which helps with upkeep.
I have a slightly smaller version and love it, the hose detaching from the head is an amazing feature. About 1 yr in a 2 cat household for cleaning up messes and theres almost no wear and tear. Use it daily DCV517B is the number
