Query: Great idea for a great product

I bought the SpotBot from Amazon on the advice of a co-worker and based on the reviews here. I was a little nervous because of some of the bad reviews but thought it was worth a try. We have basically clean carpet with lots of small spots all over so we might be the perfect market for this device.Out of the box, the sprayer didn't spray. I called customer service, got right through (bonus star!) and was told to prime the unit as follows:1. Get a bowl of warm water2. Suck up the bowl with the hose (i.e. manual mode)3. Hold down the Manual button for 30 seconds.I did and it started spraying immediately. I just cleaned up two stains that were very set-in and almost impossible to clean by hand. Wow, I'm very impressed.The only minor complaint is that the unit tends to leave an excess of water behind. This is easily managed with the manual hose which sucks it up very nicely.
