I was looking for a light-weight shampooer and with its low price I thought this would be perfect for me. Used it twice. On the third try, it wouldn't suction up the water from my carpeting. Read through the handbook. It said to clean out the "red" filter which is nothing more than an opening with a red rubber rim. From what could see, it was clean. Took it to a local vendor/repair shop. Turns out they refuse to sell it because it's known for not working after more than 5 shampoos. I was told it's the worst design ever. Word to the wise, if it's too good to be true, it's not.
