@ winonelson I'm sorry you did not get an answer, which is unusual on this forum. California has recently declared through executive order by Jerry Brown that bathroom sink faucets sold in the Golden State after 1/1/2016 may not have a flow rate greater than 1.2 gpm and kitchen sink faucets are limited to 1.8 gpm. As goes California, so goes North America, so I suspect that getting the 2.2 gpm faucet is going to get harder, not easier. Here's a trick, however. Almost all faucet flow limiters are built into the aerator, which can be removed and replaced with another aerator that allows for more flow. Even though the faucet you may be considering is rated at 1.8 gpm, there is a chance you can get an aerator from either the faucet company or an independent faucet parts supplier that has a higher flow limit. It will require some research and telephone work, but it can be done.

Here's a couple pictures of the faucet. You can see the hot/cold levers on the left and right side of the faucet. The lever in the center is how you choose between the faucet and the sprayer. When it is vertical, it sends water to the faucet and to use the sprayer you turn it 90 degrees to the left. If you look at the picture of the sprayer, there is a metal ring that you can slide over the handle to keep it depressed and be "hands free." We never use it. Also, the spray comes out in a fan shape which works great for spraying stuff off. It really doesn't flow that much water when you use the sprayer and I like that. However, the faucet puts out a really good flow - which is nice when filling pots. The sink is a Whitehaus WH3018 and is 30" wide by 18" to the back by 10" deep. We really like having one large sink instead of the traditional two. We also purchased the metal grate that goes in the bottom and had to purchase the drain fittings specific to this sink as well (we don't have a garbage disposal but it was an option). We bought it from bluebath.com but it is available many other places. I can't remember where we bought the sprayer from - I think I just kept Googling the model number and went with the best price I could find. As far as cleaning the faucet goes, we just use Clorox wipes. It has some nooks and crannies that take a little work to clean out but it's not too bad at all. The "spring" part at the base of the hose slides up and down so cleaning it is easy (though it really doesn't get that dirty). Again, I highly recommend both the sink and the faucet. Have had no issues with either. I looked around at some of the quasi-commercial faucets from some of the big-name manufacturers and they were way too expensive. I don't know what these faucets cost today but I don't think we spent more than about $300 or so. But it should last us FOREVER.

No spray on the Unico. Just pulldown. I've linked you to the Vela D, which is similar and does have the pulldown spray. I believe it's margieb here who has one and loves it. Scroll down to see the Vela D installed in her kitchen. The link below showcases mgs, dornbracht and kwc faucets in a couple of categories. very handy. I priced the Vela D 3 years ago and the price seems to have dropped a good deal. Here is a link that might be useful: mgs faucets

I have the grandma of the faucet you're looking at so no, no adjustment on mine. Yes, it's the Tara plus the sprayer. Expect you know Dornbracht is the peak of high end -- Grohe has a fine rep but comparables are really mgs progetti, Triflow and Barber Wilsons. Mine has been a great investment as the cost has tripled since I bought it. It's their satin nickel finish. Here's a snap of my sprayer stream just for reference.
