Question: is this electric or can it be plugged into the car's cigarete lighter outlet?
Document: I would recommend buying, used in my 09 Buick Enclave plugged right into built in ac outlet; great suction power with turbo head cleans very well and the many attachments are quite useful. Got tired of using commercial vacuums at Gas stations and Car Washesthey always cut off just before you finish with me rushing from side to side, front to back and want another dollar. Now I just take my time and do it right.
We purchased the Metro vacuum, with some misgivings, mainly for vacuuming our newly carpeted stairs. The fear was that the motor would not be powerful enough.) It does a great job, and as an added bonus, we now have an easy way to do other small jobs, such as lampshades. The attachments are quite useful for a variety of jobs around the house. One  small caveat: if your outlet is not close enough to the job, the cord may not be long enough. It worked fine for us, though.
I really like this little vacuum. I ordered it months ago and I use it 2-3 times a week to clean up pet fur, it picks up the sand out of my carpeted floor areas, small and light to clean miniblinds, and I also plug it into an outside wall outlet to vacuum the car interior. The power cord just is long enough, however, I wish the hose attachments didn't slip off so easily. Maybe a screw and lock technique would be a little better. Other than that, I'm still pleased as it has performed better and so far lasting longer than some cheap brands from a local department store.
this vacuum is very powerful, yet is light and looks nice. Its sound is not unbearable. For staying in a small room with wooden floors, this vacuum performed flawlessly for me. Very satisfied with my purchase.
Very happy with purchase.The vacuum is well constructed of metal housing.It is powerful for its size,and is great to clean inside my new car
This vac has adequate power, but the hood that is removable for cleaning turns with so little effort that I have had it frequently come loose while I am vacuuming.
This thing could suck the spots off a leopard yet with the included attachments it can be gentle. It's the size of a medium sized thermos bottle with a handle yet after you turn it on you'd swear you were using a full sized canister vacuum. High quality, light weight, powerful, stainless steel construction, 5 year motor warranty, UL Listed and best of all... It's made in the good 'ole USA!
This product has met all of my expectations. It is a powerful, small hand vac that picks up crumbs, lint, etc. Really the only less-than-optimal features are the lack of a cord storage mechanism and the lack of a reusable filter (of course I knew these things before I purchased it).
The product quality is great. The size depicted is somewhat deceiving as there is no point of reference to determine size in the photo. I find this a bit misleading, hence the four-star rating. It is a nice product, but realize that it is very small.
Powerful suction power. Appliances (including rug beater/sweeper) work very well. I can carry it in my repair case and use it at my clients' locations to vacuum out PC workstations, etc. For those that may wonder, the cord measures at approximately 10.3ft.
Answer: It isn't made for that purpose but you can get adapters that will work.
