I've had my (fully automatic) Nitty Gritty 1.5 FI for 17 years. It's been serviced twice in that time, and still performs flawlessly as far as I'm concerned. It is a little noisy when you turn on the vacuum, but it's so powerful you only need to run it for 20 sec. or so.
The one caution, is to avoid cleaning solutions with more than 20% alcohol as they can ruin the pump and tank. I don't use alcohol-based solutions (anymore!) so for me that's a non issue.
