The Jura Impressa XJ9 Professional, with its 135-ounce (!) water tank, is aimed at offices, which is probably why Jura puts the word "Professional" in its name. The price is high enough that corporations are probably the only ones who can afford it, though if you're looking for a way to splurge on yourself or your family, it would make a really nice addition to your kitchen (and the water tank would probably need descaling before you could make enough espressos to empty it). Both the drip tray and the dregs tray are supersized, so the machine can accommodate a lot of users before it even needs to be cleaned; the external milk carafe is gigantic as well. While not quite as high-end as the Jura Giga 5 and the Giga W3 Professional, this is still about as spectacular a coffee machine as anybody who doesn't own a Starbucks is likely to need.
It's probably not even necessary to say that the XJ9 has a full-color display that lets you select between a cappuccino, espresso, latte machiato, hot milk, hot water and even an ordinary drip coffee or that you can set the volume, strength and temperature of those drinks from the same display. You can adjust the milk frother to create different consistencies of froth for cappuccinos and lattes, and you can set the temperature for that froth. The height of the spouts is adjustable, so office workers with different sizes of mug will all be happy. There are rinsing, cleaning and descaling programs so that you have to put minimal effort into keeping your unit clean.
This machine is also designed for looks, so your boss can impress clients or you can impress the guests at your next house party. The exterior is stainless steel and the bean hopper is a small bowl on top of the machine with a finish that's so reflective you can see yourself (and most of your kitchen) in it. If you don't think good looks and programmability are worth the high price tag, you should probably lower your sights a bit, until they end up on a lower-end machine like the Philips Saeco Royal One Touch.
The menu system gives you more drink options that you will ever need and the ability to control volume and temperature will keep the engineer types happy.
For the first two years, it worked flawlessly but after that, we have had problems.
The steamer on the Jura only manages to make 2 or 3 lattes in a row then hisses and spits until you completely clean the frother.
It is very similar to the home version only with a larger water reservoir and larger capacity for grounds as well as a separate hot water tap.
