Both machines promise frozen margaritas at home, and both end up on the same wish lists, but they work in opposite ways. A margarita machine such as the Margaritaville Bahamas shaves ice into fine snow and blends it with your drink in a minute or two. The Ninja SLUSHi uses no ice at all: it chills the drink itself with a compressor, like the slush machine at a gas station, and keeps it frozen for hours.
That one difference decides almost everything else: how fast the first drink arrives, how much you can make, what has to go into the recipe and how the machine fits into a party. This guide sets the two side by side, explains each difference in plain terms, and helps you decide which belongs on your counter.

Quick verdict: margarita machine or Ninja SLUSHi?
Buy a margarita machine such as the Margaritaville Bahamas if you want a frozen margarita within minutes of guests arriving, like to adjust each round by hand, or prefer a low-sugar recipe: it only needs a bag of ice. Buy the Ninja SLUSHi if you want to make one large batch ahead, keep it frozen and undiluted for the whole afternoon, and do not mind planning 15 to 60 minutes ahead and keeping sugar in the recipe.
The rest of this page explains why, difference by difference.

How each machine freezes the drink
A margarita machine is really two tools in one body. Ice goes into a reservoir on top, a blade shaves it into fine snow that drops into the jar, and a second blade mixes the snow with your tequila, lime and sweetener. Margaritaville’s Shave ‘n Blend cycle does both in one press, and the Bahamas also lets you run Shave Only or Blend Only by hand. Shaving before blending is what gives a finer texture than ice crushed in an ordinary blender.
The Ninja SLUSHi works like a small commercial slush machine. You pour the liquid into a clear vessel, and Ninja’s RapidChill system spins an auger around a refrigerated cylinder, freezing the drink a layer at a time until it turns to slush. Nothing is added to the drink, so the last glass tastes the same as the first. Ninja’s five presets are Slush, Spiked Slush, Frappé, Milkshake and Frozen Juice, and you can nudge the texture thicker or thinner than each preset.
Ice or no ice, and why it matters
Ice is the margarita machine’s fuel. Every round needs a reservoir of it, so for a party you need a couple of bags and a cooler to keep them in. The ice also becomes part of the drink: shaved ice is frozen water, so a frozen margarita is always a little more diluted than the same recipe shaken and strained. That is why frozen margaritas are usually made a touch stronger and sweeter than ones on the rocks, as our guide to frozen versus on-the-rocks margaritas explains.
The SLUSHi needs no ice and adds no water. What you pour in is what comes out, only colder and thicker, which keeps the lime and tequila flavor intact. The trade-off is that the recipe has to freeze on its own, and that depends on its sugar and alcohol, covered below.
Speed: a drink now or a batch later
This is the biggest practical difference. A margarita machine makes a jar in the time it takes to run one shave-and-blend cycle, so you can start making drinks when the doorbell rings. If the first round comes out too thick or too thin, you shave a little more ice or blend a few seconds longer and the next round is right.
The SLUSHi needs time. Ninja says drinks take 15 to 60 minutes depending on the ingredients, the volume and how cold they are to start, and the UK listing gives “as little as 30 minutes”. Gourmet Traveller, reviewing the same Professional model in Australia, had a frozen cocktail ready in about 15 minutes. Chill the mix in the fridge beforehand and start the machine before guests arrive. Once it is frozen, though, it stays ready: Ninja says the compressor holds the slush for up to 12 hours, so the second, third and tenth drinks are instant.
Capacity and how many people each one serves
The Bahamas makes 36 ounces a round, about three or four drinks. For a small dinner that is plenty; for a crowd, you refill the ice and the jar again and again, and someone has to stand at the machine.
The SLUSHi’s vessel holds 88 ounces with a maximum of 64 ounces of liquid, which Ninja rates at seven or more servings, and you can top it up as it empties. Gourmet Traveller notes that the machine’s guide sets a minimum fill of about 500 ml, roughly 17 ounces, so it is less suited to making just one or two drinks. Over an afternoon, where people come back for refills, it serves more people with less work.
Alcohol and sugar: what each maker requires
A margarita machine has no published sugar or alcohol requirement, because the ice does the freezing. You can make a low-sugar margarita, a strong one or a virgin limeade with the same settings, and the Bahamas comes with a shot glass and recipes to start from.
A compressor machine is pickier, because sugar and alcohol both lower the freezing point of a liquid. Ninja states that drinks must include sugar or a sugar alternative, and that sugar-free recipes will not slush on their own without one of its recommended substitutes. Gourmet Traveller reports that the Frozen Cocktail setting expects at least 4 percent sugar and between 2.8 and 16 percent alcohol by volume. Ninja’s own US site does not give a figure for this model; it lists limits only for other SLUSHi models, up to 16 percent for one and up to 20 percent for the newer XL and Twist machines.
In practice, that ceiling is generous for a margarita. Our arithmetic: a full 64-ounce batch at 16 percent alcohol contains about 25 ounces of 80-proof tequila, roughly 17 US standard drinks by the National Institute on Alcohol Abuse and Alcoholism‘s definition of 1.5 ounces of spirits. Measure the tequila rather than pouring by eye, follow the recipe guide that comes with the machine, and keep an alcohol-free option for drivers and anyone under 21.
Noise, size and where each one lives
Neither maker publishes a decibel figure. A margarita machine runs its motor in short bursts, only while it shaves and blends. The SLUSHi runs longer, churning while it freezes and then holding temperature, and Ninja says its WhisperChill compressor does that quietly. Gourmet Traveller found the churning “a little noisy”, comparable to a kitchen extractor fan in an open-plan room.
Size is closer than you might expect. The Bahamas measures about 14 by 9 by 18 inches with its ice reservoir on top. Ninja’s UK site gives the SLUSHi as about 6.5 inches wide, 16.3 inches deep and 16.9 inches tall, and it weighs about 11 kg (24 pounds), according to Ninja UK and Gourmet Traveller, who called it bulky. Both need clearance under wall cabinets, and the SLUSHi is heavy enough that you will want a permanent spot for it during the season.
Cleaning up after a sticky batch
Both are reasonably easy. Margaritaville lists the Bahamas’s parts as dishwasher safe. Ninja lists the SLUSHi’s parts as dishwasher safe as well, with a detachable lid and drip tray and a rinse cycle, and Gourmet Traveller found clean-up straightforward, with the removable parts going on the dishwasher’s top rack without heated drying. With either machine, rinse it on the day you use it: sugar and lime juice turn sticky fast.

Our pick on each side
These are the two machines we recommend if you have decided which way to go. Both are also reviewed in our guide to the best margarita machine for home, along with larger shave-and-blend models, the two-flavor SLUSHi Twist and a blender alternative.
1. Margaritaville Bahamas Frozen Concoction Maker – Shaved Ice in Minutes
The Bahamas is the plainest machine in the Margaritaville range, and that is why it is our pick on this side. It does one job well: an ice-shaving blade in the top-mounted reservoir drops fine snow into a 36-ounce jar, where it blends with whatever you have poured in. One press of the automatic Shave ‘n Blend cycle makes a round of three or four drinks.
The manual Shave Only and Blend Only buttons are what make it practical. If a round comes out too thick, blend a little longer; too thin, shave in more ice. The shot glass and recipes that come with it give you a starting point for the ratios.
Margaritaville lists the parts as dishwasher safe and gives the size as about 14 by 9 by 18 inches, so check the height under your cabinets with the reservoir in place. It comes with a one-year limited warranty. The listing rates it at 450 watts with dual motors.
Why we like it
- Shaves ice before blending for a fine, even texture
- Drinks in one cycle, no waiting for a freeze
- Automatic cycle plus manual Shave Only and Blend Only
- No sugar or alcohol requirement for the recipe
- Dishwasher-safe parts, per the listing
Key specifications
| Model | DM0500 |

Why we recommend it
Choose it if you want frozen margaritas on demand for a few people, with the freedom to make them as strong, sweet or tart as you like. It is quick to set up, quick to clean and needs nothing but ice.
Skip it if you host big, long parties: 36 ounces a round means refilling ice and jar often, and the drinks must be served straight away.
Pros and cons
Pros
- Fast: a round per cycle
- Any recipe, including low-sugar
- Manual control of texture
- Dishwasher-safe parts
Cons
- Needs plenty of ice
- Three or four drinks per round
- Older model in the Margaritaville line
2. Ninja SLUSHi Professional Frozen Drink Maker – Slush That Holds for Hours
The SLUSHi FS301 is the original model in Ninja’s line and our pick for anyone who wants a frozen margarita that waits for the guests rather than the other way around. Pour up to 64 ounces of chilled mix into the 88-ounce vessel, choose the Spiked Slush preset, and the RapidChill system freezes it in 15 to 60 minutes, according to Ninja.
From then on, the WhisperChill compressor holds the slush at serving texture for up to 12 hours (for recipes without dairy), and a pull of the handle fills a glass. You can set the texture thicker or thinner than the preset, and the other presets, Slush, Frappé, Milkshake and Frozen Juice, cover drinks for everyone who is not having a margarita.
The rules are the ones every compressor machine follows: the drink must contain sugar or one of Ninja’s recommended sugar alternatives, and the alcohol has to stay within the range in the recipe guide. Ninja rates it at 200 watts, the parts are dishwasher safe, there is a rinse cycle, and it carries a one-year limited warranty. Gourmet Traveller, reviewing the Australian version, found it quick with frozen cocktails but bulky and a little noisy while it churns.
Why we like it
- No ice, so the drink is never watered down
- Holds slush for up to 12 hours, per Ninja
- 64 ounces of liquid, seven or more servings
- Five presets, including Spiked Slush
- Dishwasher-safe parts and a rinse cycle
Key specifications
| Model | FS301 |
|---|---|
| Type | Compressor slush machine, no ice |
| Capacity | 88-ounce vessel, 64 ounces max liquid |
| Power | 200 W, 120 V |
| Programs | 5 presets (Slush, Spiked Slush, Frappé, Milkshake, Frozen Juice); adjustable texture |
| Size | About 6.5 x 16.3 x 16.9 inches; about 24 lb (Ninja UK) |
| Cleaning | Dishwasher-safe parts; rinse cycle; detachable lid and drip tray |
| Warranty | 1-year limited |
Why we recommend it
Choose it for pool parties, game days and backyard taco nights, when people drift back for refills over several hours. Make the batch before guests arrive and nobody has to mind the machine.
Skip it if you want a drink in two minutes or prefer low-sugar margaritas: the first batch can take up to an hour, and the recipe needs sugar or a recommended substitute to freeze.
Pros and cons
Pros
- No dilution from ice
- Holds slush for hours
- Dispenses straight into the glass
- Frappés, shakes and juice slushes too
Cons
- Up to an hour per batch
- Recipe must contain sugar
- Heavy and a little noisy (Gourmet Traveller)
How we compared the two
We compared the machines on what a kitchen asks of any frozen drink setup: texture, speed, batch size, what the recipe has to contain, and how easy the machine is to clean and store. Specifications come from Margaritaville’s and Ninja’s Amazon listings and from Ninja’s US and UK websites; where Ninja’s own figures differ by region, we used the measurements that match independent reviews. For how the SLUSHi behaves in use, we relied on Gourmet Traveller’s review. We have not used either machine ourselves, and we say whose findings each observation is.
Frozen margarita machine questions, answered
Can you make margaritas in a Ninja SLUSHi?
Yes. Use the Spiked Slush setting, keep sugar in the recipe and stay within the alcohol range in Ninja’s recipe guide. Gourmet Traveller reports a range of 2.8 to 16 percent alcohol by volume with at least 4 percent sugar for the frozen cocktail setting on this model.
Is a Ninja SLUSHi better than a margarita machine?
It is better for long parties, because it holds an undiluted batch for hours. A margarita machine is better for speed, small rounds and low-sugar recipes, because it freezes with ice and makes a drink in one cycle.
Why won’t my SLUSHi freeze my margarita?
Usually there is too much alcohol, too little sugar, or the mix started warm. Sugar and alcohol both lower the freezing point. Chill the mix first, check the sugar and alcohol against the recipe guide, and give it the full time Ninja allows, up to 60 minutes.
Does a margarita machine water down the drink?
A little. The shaved ice becomes part of the drink as it melts, which is why frozen margarita recipes use a slightly stronger, sweeter base. A good margarita mix or fresh lime with a balanced syrup makes up for it.
Which is easier to clean?
Both have dishwasher-safe parts, according to their makers. The SLUSHi adds a rinse cycle and a removable drip tray; the Bahamas has fewer parts to take apart. Clean either on the day you use it.
Our final word on frozen margaritas at home
If you want frozen margaritas on demand for a few people and full control of the recipe, buy a margarita machine such as the Margaritaville Bahamas. If you want a big batch that sits ready all afternoon without ice, buy the Ninja SLUSHi and plan an hour ahead. Either way, start with good tequila (our guide to tequila types explains which to use) and fresh lime, and serve it in a proper glass; our guide to margarita accessories covers the glasses, salt, shakers and tools that go with it.
