Both are four-tray Harvest Right home freeze dryers, built for different rooms. The Countertop 360 is short and wide, with the pump and drain pan inside, 358 sq in of tray space and 5 to 9 lb per batch. The Small Pro is tall and narrow, with an external pump and drain hose, 434 sq in and 6 to 10 lb. For a kitchen counter near people, I'd pick the 360; for volume with floor space, the Small Pro.
Countertop 360 vs Small Pro at a Glance
The Small Pro holds more food per batch, and the Countertop 360 is the one that fits on a kitchen counter with nothing outside its cabinet. Every practical figure is side by side below.
The capacity rows favour the Small Pro: 434 sq in against 358 sq in, and 6 to 10 lb a batch against 5 to 9 lb. The 360 wins on height, pump location and water handling.
Footprint: Counter Space vs Floor Space
The 360 needs one stretch of counter and nothing else. The Small Pro needs a raised surface plus room beside it for the pump and below it for a drain container, so it suits a utility room more than a kitchen.
The Countertop 360 measures 25.8 in wide, 18.5 in deep and 17.7 in high, and at 110 lb it is a two-person lift. The Small Pro measures 17.4 in wide, 21.5 in deep and 26.8 in high, plus room for its external pump and drain container.
The Small Pro also needs height under it: Utah State University Extension notes that a freeze dryer of this design must be raised so its ice-melt tubing can drain into a container below.
One user who also owns a Medium drilled through a wall and later a cart to run that Medium's hose to a bucket below. The 360 needs none of that: one cord, nothing outside the cabinet.
Under upper cabinets, the fit is tight. One user noted that many kitchens have about 18 in from counter to upper cabinets, about a quarter inch over the 360. The top is a vent that needs clearance, another user notes, and the manual asks for 1 to 2 in at the back. Harvest Right's setup page says not to place it in an enclosed cabinet or tight space. Measure your gap; if it leaves no room above the top vent, use an open stretch of counter or a rolling cart.

Trays and Batch Size
The Small Pro takes about a pound more food per batch and roughly a fifth more tray space. The 360's smaller trays are easier to fit in a home freezer for prefreezing.
The Countertop 360 trays measure 7.11 x 12.6 x 0.75 in, four of them, for 358 sq in. The Small Pro trays measure 7.75 x 14 x 0.75 in, also four, for 434 sq in. A user who owns a Small found that spare Small trays do not fit the 360, so they do not carry over.
Five to 9 lb a batch is small, the main trade-off. It suits one or two people, leftovers, garden fruit, candy, or a second machine beside a bigger one. One user summed up the split: "If your problem is space [...] this machine solves that problem. If your problem is volume, like a big garden, a family of six, hunting season, [...] the countertop 360 is going to feel small super fast". For volume, the Small Pro's 6 to 10 lb is a step up, and the Medium (10 to 15 lb) the next.
One upside: a user noted the smaller trays fit an ordinary home freezer far more easily than Medium trays, so you can prefreeze before the run. Another said the instructions call for 48 hours in the freezer and estimated it cuts about 10 hours off the run.
Pump, Drain and Daily Upkeep
The 360 has no hose, bucket or separate pump to place, and you empty a pan into the sink. The Small Pro needs a hose and container you keep clean. Oil care is the same on both.
On the 360, the vacuum pump sits on a slide-out shelf behind a door on the right side of the cabinet, and a window in that door shows the oil level without opening it. The Small Pro's Small Premier pump sits beside the freeze dryer on its own. On both, the oil is filtered or replaced every 20 to 30 batches, and both come with an oil filter and pump oil.
The Small Pro drains through a hose into a bucket or similar container, and that hose needs cleaning: one user said the hose on their older machine "gets just really yucky, including black mold."
The 360 collects melt water in a pan in the base that you pull out, empty in the sink and slide back. An owner who compared the 360 with a Small found the pan harder to empty and clean than a bucket, and noted that very wet loads at the maximum weight can fill it. The fix: empty it when the screen asks at the start of a batch, do not tilt it when full, and keep very wet loads under the maximum weight.
The one step to get right on the first run is the drain valve: close it before you press Start. Harvest Right's setup page says the manual's drain valve information does not match the machine. One user put it simply in a setup video: "If the handle is horizontal, the valve is open. If the handle's vertical, it's closed."
If you hear air whistling when the vacuum stage starts, the valve is open; turn the handle vertical. The valve is on the left side and the pump door on the right, so leave a little room on both sides to reach them.
Noise, Heat and Power in a Living Space
The Countertop 360 is quiet and cool enough to run in an open kitchen while people talk, and it plugs into an ordinary kitchen outlet. The Small Pro, with its pump outside the cabinet, belongs where noise and pump heat do not matter, such as a laundry room or basement kept between 50 and 75°F. Here is what each reading means at home.
In one test, a decibel meter read 54 dB once the pump started during vacuum freezing, about a dishwasher. In a side-by-side test against a Harvest Right Medium, measured from 3 ft and from 10 ft, the same user read about 52 dB for the 360 and about 63 dB for the Medium.
Another user's test read 48 to 49 dB from about 5 1/2 ft and about 57 dB right next to the machine. The meter readings here compare the 360 with a Medium.
A user who also runs a Medium said of the 360 "It is so quiet," and that with the Medium running in their lab "we can hardly even hear each other speak." Another compared the sound to a washing machine on a normal spin cycle: "The noise is constant and it is noticeable, but it really doesn't seem bothersome to me."
For power, one user metered one 23 hour 46 minute run of two trays of cereal bars, not prefrozen: "our total electricity usage for this whole cycle with two trays 9.717 kilowatt hours and this is our maximum wattage on the cycle with 741 watts." Another measured about 300 W at full vacuum against almost 500 W for a Medium, which they put as "the countertop 360 is pulling about 40% less power when it's under full vacuum." Neither needs a 220 V circuit; Harvest Right recommends a dedicated 15 A circuit for the 360 and requires one for the Small Pro.
On heat, a user took infrared readings about two and a half hours into pump running: 89°F at the top vent and 86°F at the back vent, close to skin temperature, concluding that "the heat on the inside of this freeze dryer is staying on the inside of the freeze dryer."
Price and What Each One Includes
The 360 costs less and keeps the pump and water inside one cabinet; the Small Pro costs more and holds more per batch.
The Countertop 360 is the lower list price of the two (see the matrix). Some Small owners point out that they paid about what a 360 costs when the Small was on sale. The answer is what each buyer gets. The Small Pro holds more, 434 against 358 sq in, and it is the better buy for volume when you have floor space for its pump and drain container. The 360 is the counter machine: quiet enough for a kitchen, one plug, and the pump and water inside the cabinet.
The boxes differ too. The Small Pro ships with the larger Mylar starter kit, 50 bags and 50 oxygen absorbers against 25 of each, while the 360 builds its pump and drain pan into the machine, so there is no bucket or separate pump to place before the first run.
Which One to Buy
If the machine lives on a kitchen counter where people walk past it, buy the Countertop 360. It is short, it read about 11 dB quieter than a Medium in one user's side-by-side test, its pump runs inside the cabinet, and it plugs into a single 110 V outlet. One owner who compared the two liked that "the door redesign doesn't need adjustment": the 360 latches with a twist lock, where older models needed the seal lined up to avoid vacuum errors, as one user notes.
If throughput matters and you have floor space for a pump and a bucket, buy the Small Pro. The same owner came down on that side: "I personally would rather purchase a small versus a countertop 360 if choosing between the two." I'd let the room decide. The 360 gives up about 76 sq in of tray space and a pound at each end of the batch range in exchange for a cabinet that keeps the pump and the water inside.

Pick by Household
If you need more than 10 lb a batch, neither four-tray model fits; the Medium handles 10 to 15 lb. The Countertop 360 first look places it in the lineup, and the Harvest Right Countertop 360 review covers it on its own. To compare other machines built for a counter, browse countertop freeze dryers, or the full range of home freeze dryers.
Both are covered by Harvest Right's manufacturer warranty, the most cost-effective path for service: the 360 has a full one-year warranty, then limited coverage in years two and three, and the Small Pro has a three-year limited warranty. If a delivery issue comes up, we work with you case by case to get it resolved quickly.
Frequently Asked Questions
- What is the difference between the Harvest Right Countertop 360 and the Small Pro?
- The Countertop 360 is short and wide (25.8 in W x 18.5 in D x 17.7 in H), with the vacuum pump and drain pan inside the cabinet and 358 sq in of tray space. The Small Pro is tall and narrow (17.4 in W x 21.5 in D x 26.8 in H), with an external pump and a drain hose to a container, and 434 sq in of tray space.
- Which holds more food, the Countertop 360 or the Small Pro?
- The Small Pro. Its four trays total 434 sq in and take 6 to 10 lb of fresh food per batch, against 358 sq in and 5 to 9 lb on the Countertop 360, roughly 21% more tray area.
- Do Small Pro trays fit the Countertop 360?
- No. The Countertop 360 trays measure 7.11 x 12.6 x 0.75 in and the Small Pro trays 7.75 x 14 x 0.75 in. A user who owns a Small found that spare Small trays do not fit the 360.
- Which is quieter, the Countertop 360 or the Small Pro?
- The meter readings here compare the Countertop 360 with a Medium. One test read about 52 dB for the 360 and about 63 dB for the Medium in a side-by-side test, and 54 dB for the 360 during vacuum freezing. The 360's pump also runs inside the cabinet rather than beside it.
- Which uses less power, the Countertop 360 or the Small Pro?
- The power tests here are on the 360. One user recorded a 741 W peak and 9.717 kWh for one two-tray run on the 360, and another measured it at about 40% less power than a Medium at full vacuum. Both run on a standard 110 V outlet; Harvest Right recommends a dedicated 15 A circuit for the 360 and requires one for the Small Pro.
- Is the Countertop 360 worth it over a Small Pro?
- Yes, if the machine lives on a kitchen counter and quiet running and a one-plug setup matter more than capacity. If you want more food per batch and have floor space for a pump and drain container, the Small Pro is the better buy even though it costs more at list.
- Will the Countertop 360 fit under my kitchen cabinets?
- Measure first. The 360 is 17.7 in high, and many kitchens have about 18 in between the counter and the upper cabinets, which leaves little room over the top vent. Harvest Right says not to place it in an enclosed cabinet or tight space and the manual asks for 1 to 2 in behind it; if the gap is too tight, run it on an open counter or a rolling cart.
