Description
The Keurig K155 Office Pro is a commercial pod brewer that appears in this catalog alongside domestic machines. Keurig records a silver color, dimensions of 10.38 inches deep by 14 wide by 13.8 tall, a timer, a removable tank and programmable operation, a reusable filter type, office use as a recommended use, a metallic exterior, fully automatic operation, 120 volts, a touchscreen interface, USA country of origin, model K155 Office Pro Commercial and first availability in May 2012. The description adds a full color touchscreen for brew temperature and auto on and off programming, a 90 ounce removable reservoir described as brewing up to 18 cups, four brew sizes at 4, 6, 8 and 10 ounces, and a drain and store function.
Two fields are simply wrong and should not be repeated. The coffee maker type reads Pour Over, which this is not: it is a single serve pod brewer. And the coffee filter size field reads number 6, which is a paper cone filter size and has no meaning on a machine that brews from sealed pods. Both are import artifacts. The listed weight of 6 pounds is also implausible for a commercial brewer of this size.
What it is and where it fits in a home
This is office equipment. The 90 ounce reservoir, the commercial designation and the drain and store function all point at a shared kitchen rather than a domestic one, and that is where it belongs.
In a home it makes sense in one situation: a household that gets through a lot of coffee and is tired of refilling a small tank. Domestic Keurig machines in this catalog such as the Keurig K-Mini and the Keurig K-Elite carry much smaller reservoirs, and the difference between refilling twice a day and twice a week is the main practical argument for a commercial unit at home.
At 14 inches wide and 13.8 tall it needs real counter space and clearance above to lift the lid and load a pod.
Living with it day to day
Four brew sizes from 4 to 10 ounces is a wider range than most domestic pod machines offer, and the small end matters as much as the large one: a 4 ounce brew from a standard pod is a strong concentrated cup, and a 10 ounce brew from the same pod is a weak one. The size selection is effectively the strength control on any pod brewer, which is worth understanding before expecting a strong setting to do something else.
Programmable brew temperature is a commercial feature that domestic machines rarely offer, and it is a genuine adjustment rather than a gimmick: extraction temperature changes the taste of the same pod.
The 90 ounce reservoir at 18 cups is the headline. In a household of two coffee drinkers that is several days between refills, and the reservoir is removable so it goes to the tap rather than the machine going to the sink.
The drain and store function empties the internal tank, which is the feature that stops water sitting stagnant inside a machine that is about to be moved or left unused. That is a commercial concern that applies equally to a holiday home or a machine going into storage.
Keurig publishes no noise figure. Pod brewers are loud in short bursts, which is a different problem from continuous noise and is over in under a minute.
Controls and what works without an app
There is nothing connected. No Wi-Fi, no app, no account. A full color touchscreen is the interface and everything runs from it with the machine plugged in.
A touchscreen on a 2012 appliance with no network dependency is an interesting combination and a durable one. Brew temperature, auto on and off scheduling and cup size all live in the machine, which means the scheduling that a connected machine would sell as a smart feature is available here from the panel, and it will keep working regardless of any software decision.
The auto on and off is the practical part of that. A machine that heats itself before the office opens is doing the same job a remote start would do, without the phone.
Running cost and upkeep
Pods are the running cost and they are the dominant one on any pod machine. The listing describes the filter type as reusable, which on a Keurig usually indicates compatibility with a refillable pod that takes ground coffee, and that is the one way to change the ongoing cost of the format. Nothing in this listing confirms that a reusable pod is included.
Descaling is the maintenance that decides how long a pod brewer lasts. Every machine that heats water in a small internal tank will scale up, and in a hard water area a machine that is not descaled on schedule will slow, then under fill cups, then stop. Keurig does not publish a descaling interval on this listing. The drain and store function helps with stagnation but does nothing about scale.
The needle that pierces the pod is the other maintenance point and it clogs with grounds over time, which produces weak cups that are usually blamed on the pods.
Electrically, Keurig publishes 120 volts and no wattage and no amperage. A pod brewer draws hard while heating, which is a short burst rather than a sustained load, and a commercial unit with a 90 ounce reservoir heats more water than a domestic one. The rating plate is the source, and in an office kitchen the circuit is worth checking against whatever else is on it.
Highlights
- A 90 ounce removable reservoir, described as up to 18 cups between refills.
- Programmable brew temperature, which domestic pod machines rarely offer.
- Four brew sizes from 4 to 10 ounces, a wider range than most.
- Auto on and off scheduling that works from the panel with no app involved.
- A drain and store function for transport or periods of disuse.
Things To Consider
- The coffee maker type field reads Pour Over, which is wrong for a pod brewer.
- A number 6 paper filter size is recorded, which has no meaning on this machine.
- The listed weight of 6 pounds is implausible for a commercial brewer this size.
- No descaling interval is published, and scale is what ends these machines.
- No wattage or amperage is published, only the voltage.
Who it is not for
A one person household does not need a 90 ounce reservoir and should look at the compact machines in the single serve brewer category. Anyone who wants milk drinks at the touch of a button needs a machine with a milk system, such as those in the wider coffee machine category. Anyone in a hard water area should plan a descaling routine from the start whichever machine they buy. And anyone comparing this against the Nespresso Vertuo should note that these are different brewing systems using incompatible capsules.
