Received as part of the Amazon Vine reviewer program, the Carrand AutoSpa Bagless Auto-Vac turned out to be a pretty good portable vacuum for small jobs.Carrand is a brand that I was unfamiliar with, so I looked them up.  Around since 1983, they specialize in a niche market - quality auto detailing and car care on a budget. This product definitely fits that bill.  It's not a heavy-duty shop vac, but for light, small, dry jobs for cars, boats and RV's it would be a good choice. Having lived aboard a sailboat for three years and having used a similar product, I can say that I would have loved having this one instead for its lightweight build and suction power.The vac comes with three attachments and essentially a fourth built in to the hose; this slides inside each attachment and is angled to be used along narrow spaces.  The hose is about 3' long and about 1.5" in diameter.  You're not going to want to suck up marbles with this one, although suction-wise, I'm sure it has the power to do so.The exhaust (opposite end of the canister from the intake hose) forcefully blows air when running.  You could use it to blow off things... it's that powerful!  I can't see myself using that feature, but good to have I guess.The bag that catches the debris that is sucked into the vac - yes, there is a receptical that I would consider to be a 'bag', thus this is truly not a bagless vac but rather a re-usable bag vac - is very small, but so is the unit.  You are not going to be able to vacuum up a ton of dirt and dog hair out of a 4x4 pick-up owned by a logger in one run through the cab, but two swipes should get it pretty clean!  Perfect for detailing most vehicles except for the vac capacity and the short cord.The only real negative I found when using this powerful little auto-vac was the short cord.  The containment system for the cord (wrapping around the base with a notch for the plug to be protected underneath) is great, but oh how I wish there was more length to the cord itself.  For most jobs, you will need an extension cord handy when using this item.If you want a lightweight vac with powerful suction for small jobs around the house and/or cleaning out your vehicles, this is a good choice.  Just be aware that it won't vacuum up wet things (that would gum up the bag in the 'bagless' vac) or a lot of debris at one time.  You will also need an extension cord for most jobs.UPDATE: 5/10/11I used this vac to detail two of my vehicles.  As stated above the suction is great and yes, extension cord needed.  On the negative side, I discovered that durability of the rubber coating on the end of the attachments that would be placed against the carpet is an issue.  After one vehicle - the rubber was tearing off.  I'm not particularly hard on tools of this type, and the carpets were not in need of lots of rubbing, so this bothered me a bit. I was also not thrilled with the 'bag' that needs to be frequently emptied, which for me meant dumping the large debris and then folding it inside out and tapping it several times to get the fine dust out of it it.  The bag is made of a fiber cloth and there's no real way to clean it, thus the fine dust may (over time) affect the vac's suction ability as it would block airflow through the vac.This vac is still one of the most powerful of its type I've ever used, but durability of the attachments and the unit itself may be an issue.  I'm going to treat mine very gently and hope it lasts.
