First let me say there are already plenty of very good reviews of this coffeemaker so I can't really add much to what has already been written. I decided to add my 2 cents worth in regard to the technique used to clean up after the brewing process since this can be a very messy task if not done carefully.
The first time you "pop the filter" while looking down into the bowl you will understand why a cleaning technique has to be developed. My first experience ended up with a face full of brown speckles as the filter unsnapped and the Kona grounds exploded like a Hawaiian volcano. In case you are wondering, yes I still have my eyesight but only because of my cat-like reflexes. Six months later and I still find a grind or two in my ear canal as they work themselves back to the surface.
So, I decided I needed to develop a cleaning technique to avoid future exposure to flying grounds. I thought first about the use of safety glasses but concluded that while my eyesight would probably be saved, I would still have to deal with brown speckles on the kitchen ceiling.
Then I remember something my dear Mother told me about coffee grounds (no, not that they will put your eye out...). Mom managed a plumbing business as her last career position (she would still be working there but one can take just so many butt crack exposures before you have to move on...). She told me that contrary to popular belief, all the plumbers actually encouraged people to put their coffee grounds down the disposal or kitchen sink drain. Oh sure, you skeptics out there (you know who you are) are thinking this was a powerful marketing technique put forth by the plumbers union to increase repairs and build up market share. However, consider their logic. These drains have a tendency to accumulate oils, grease, and other disgusting things we all wash down the sink from time to time. Coffee grinds actually will act as a sort of sandpaper or grit to help bind with these cloggers and help them flush down the drain. If you have a disposal the grinds will also help clean up the blades. At least that was the plumbers theory and you are not going to make a living trying to argue physics with a plumber.
Why did I explain all this to you, dear readers (I almost forgot myself). Because here is the clean-up technique I developed, now available at no cost to each and every one who owns this remarkable coffee machine. (If you are thinking "you get what you pay for" you should not be such a skeptic -- this is the INTERNET where almost everything is free!) You must first subscribe to the validity of the advice provided to me by my Mom via the plumbers union. If you do not, just stop reading this now and check out some other excellent reviews at coffeegeek.com - do not waste your time if you don't have faith in my Mom's sage wisdom.
Take the upper chamber over to the kitchen sink. Almost forgot, make sure you remove the cover that snaps on to the upper chamber. Invert the chamber so that the tube is directly under the faucet. As you hold the tube tightly, turn on the water and use whatever athleticism you posses to make the water stream flow directly down the tube. I also use a move called the tube twirl that turns the chamber in a clockwise direction that helps direct the water to all areas of the chamber. Counter-clockwise should also work if you are in the Southern Hemisphere. My suggestion is not to get too fancy with these advanced techniques until you have mastered the basics.
After a minute or so, most of the grinds have safely and securely been dispatched to the disposal or drain. You may now safely proceed to the next step which is to invert the chamber back to where the tube is facing down (this would be South in the Northern hemisphere). If you completed the first step correctly, there are very few grinds left on the filter. You may now "pop" the filter out without the use of safety glasses and not have grinds explode onto your ceiling.
Wash the filter under the water. Last step, you will have a few remnants of coffee clinging for dear life to the sides of the chamber. Regardless of your water pressure, these cannot be removed just by running water. You must apply a sponge, towel, or cleaning cloth of your choice along with a little elbow grease to remove these hangers-on. I have not found a technique that eliminates this last bit of hard work but I pledge to you I will continue my R&D until we have a cleaning process that is fun, enjoyable, and requires no expenditure of your energy whatsoever. That would meet your expectations, right?
My sincere hope is that you will not let the clean-up process stop you from having a wonderful java experience as you sip a near-perfect cup of Joe from your Bodum.
