Both the K150 and K155 are part of Keurig’s commercial product line: the OfficePRO series.
They featuring a simple one-button brewing system, a colorful user interface and even bi-lingual compatibility.
Neither is My K-Cup compatible.
And I’d actually like to take a second to point out a nuance here. There are actually 3 different models of OfficePRO brewers:

Keurig K150 vs K155: The Differences
Take a look at the table headers and you’ll see we’ve grouped the K150/K155 together and contrasted them with the K150P.
That’s because the K150 and K155 are the same brewer. They are compatible with direct water line plumbing, and you can buy a kit to do that.
The K150P comes pre-assembled with direct water line plumbing so you don’t have to do it yourself.
All three models have impressive 90 oz water reservoirs, which are good for about 7-14 servings (depending on the brew size).
For some business or office break rooms, the reservoir alone might be sufficient.
For settings with higher throughput, re-filling the reservoir so frequently may be challenging. Keurig makes models which offer direct water line plumbing:
The K150/K150P/K155 is generally the much more affordable option for break rooms, cafes, lounges, or other commercial areas.

Which model is right for you?
Choose the K150P if you want direct water line plumbing but don’t want to do it yourself. This model comes pre-assembled and is ready to go from the minute it arrives.
Choose the K150/K155 if you want the commercial model with its behemoth of a water tank (90 oz) but don’t want direct water line plumbing. Alternately, if you can get a good deal on a Keurig K150 or K155 and want to purchase the direct plumbing kit separately, you can do that, too.
