The Apple Way
Apple has created a support page that explains, in large, how to create a bootable USB drive with the OS X 10.9 Mavericks setup file on board. It is not very detailed (which is where the following steps come in), but is to be preferred over dedicated, third-party tools as it is properly tested.
That being said, this option is only aimed at those whose Macs are already running the latest iteration of the Mac operating system, according to the support page. I have not tested Apple's claims, to see whether it can be used successfully with prior versions. (Try it; if that is not the case skip past this section and look at the next one.)

Here is what you need to do:
As there is no progress bar or percentage indicator, there is no way of knowing how much time the process will take to complete. It mostly depends on the speed of your USB drive. It should take 30 minutes at most (it is not a rule, just a personal observation based on my experience).
Using DiskMaker X
DiskMaker X (formerly known as Lion DiskMaker) is a third-party tool that almost automates the process (you will have to press a few buttons), and is suited for creating a bootable OS X 10.9 Mavericks USB drive even when your Mac is running an older version of the operating system like Mountain Lion. There is a caveat though: its creator says the app does not work as intended on Snow Leopard version 10.6.8 and older. I recommend using it only when the first method does not work.
Here is how to use DiskMaker X:
DiskMaker X will inform you on the amount of time left to complete the process, as opposed to the tool Apple offers. To install OS X 10.9 Mavericks on your Mac, restart the device, press the Option key immediately after, select the USB drive you just created from the menu, to use it, and follow the guide shown on the screen to finish the install.
It’s finally here – yes, Apple has finally released OS X Mavericks to the public! With the public release, Apple has changed the necessary steps required to build a fully functional bootable USB installer for the preview.
A USB install disc can be an important tool to quickly and easily install a fresh copy on your Mac, without first having to install OS X Mountain Lion and then upgrade using the Mac App Store method. Since Apple has changed a few things since their first developer preview, we’ve got a new method for creating a USB install disc also – and this one should work for many versions of OS X to come.
Note: While the old method still technically works, it will not install a Recovery Partition, whereas this new method will. Before you proceed, please note that you will need a flash drive at least 8GB in size or larger.
Here’s how to make it work, courtesy of some helpful instructions from MacRumors forum member tywebb13:
Your 8 GB USB drive should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Mavericks.app and should be in your Applications folder.
Run this in terminal and wait about 20 minutes:
sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X Mavericks.app --nointeraction
You should see something like this:
Erasing Disk: 0%… 10%… 20%… 100%…
Copying installer files to disk… Copy complete. Making disk bootable… Copying boot files… Copy complete. Done.
Patience is key. The process can take up to 20-30 minutes to finish, even though Terminal may not look like it is doing anything. Make sure to wait until you see the “Done.” prompt before exiting Terminal or interrupting the process.
That’s all there is to it! For reference, the original method of creating a USB boot drive can also be found at this link.
Update (10/24/13): Fixed a minor issue in how the code was displayed, and updated to reflect the public release of Mavericks.
