I was in the market for a deep carpet cleaner and wanted to find something that would be easier to use than the commercial rug cleaner you would typically rent from a store, something that was quieter, portable-friendly, and more than capable of handling some common carpet stains from high-traffic areas in the home. After reading some reviews, I chose this particular product, and was pleasantly surprised at how well it worked as advertised: it deep cleaned my carpet, lifted the stains in one go, quickly dried several areas as I finished another room, and remained relatively quiet like our vacuum.
Aside from the many positive things about it, there were a few minor negatives during the whole cleaning process: for one, this unit definitely burned through warm water relatively fast, so I needed to empty the water tank and refill it about 2-4 times more than the dirty water tank, but it only took a couple of minutes to stop in between carpet treatments; second, depending on how much carpet area you want to touch up on, expect the small carpet cleaning solution reservoir to be the next thing to have to refill with another bottle, but this part lasted longer than expected, getting through a whole living room; and third, the product, through constant use, does in fact get heavier over time, so expect it to weigh more than when you began as it collects the majority of the water you had originally poured into it--your arm will get fatigued after 10-15 minutes.
In my overall experience with this cleaner, I still highly recommend it to get the job done at its current market price, so you are definitely getting more bang for your buck right now during the shopping season. I just recommend you pick up 2-3 bottles of cleaning solution too! It is definitely easy to assemble and disassemble, clean out all working parts with water, and makes cleaning your carpet very easy, and seeing the results as you go is definitely rewarding.
