Okay, if you're reading many of the reviews, you know the suction on this is a bit low...it's true, but it's not super terrible.  It will pick up small things, though it does a better job of picking up things it can wrap around its brush for you to pick off later than it does things that it can suck into its little tank.

Basically, I found it adequate.  As a handheld vacuum, you can do better, but the water tanks are a nice feature if you'd like to skip using Woolite and scrubbing by hand.

The brushes do a good job of beating out the stain and are relatively easy to clean.

The tank is easy to fill and the dirty water tank easy to empty.

There is a safety circuit on the cord (like in most bathrooms) that will trip to avoid electric shock if you get it wet or have other issues.

My biggest complaint was that I used it to clean cat puke.  Even though I'd scooped up, most of the mass, there were some bits and chunks left on the carpet.  I followed the directions and indeed, it cleaned up nicely with no stain after using the Spotlifter and all the "bits" were gone.  The carpet was quite wet after (see all the other reviews on low suction).

Unfortunately, clean up was gross!  The brushes were full of grossness and I had to wash those by hand.  The dirty water tank wasn't a problem, at least.  But after removing those two things there are cylindrical tubes that run through the body and the suction lip up front, both of which had all sorts of unpleasantness.  I ended up just taking the whole thing to the sink and running water over it (unplugged of course) and had to use my fingers to wipe it out.  (And lest you say it's my fault and I'd have to do that for anything I used to clean up cat puke, I can tell you that's not true...with the Spotbot, you just suck water through it and it cleans itself.)

I think I'd use this mostly like a handvac because I don't have one, but if I did I don't know if I'd have a strong use for this...I have the Bissel Spotbot as well, and frankly it is MUCH easier to use, easier to clean, and has better suction.  Plus, I think it does a better job with its various beaters and brushes than this does.  It also has a way to disconnect the hose and get into even smaller areas than this can, though it doesn't have the beater brushes that way.  I guess this might do better if you had a really difficult job in a small area.

This isn't bad, but if you're really just looking for a handvac, get that.  If you want a deep cleaner, get that.  If you need a deep cleaner that takes up less space in your closet and works more like a hand vac, I suppose that's the niche for this.
