Ninja Hot & Iced XL CM371 Review — Versatile 12-Cup Coffee Maker

intro

The Ninja Hot & Iced XL Coffee Maker (model CM371) positions itself as a do-everything countertop brewer: single-serve cups and travel mugs, classic drip pots, bold "rich" shots, an "over ice" mode for iced coffee, and a rapid cold-brew option. The listing calls out a 12-cup glass carafe, an easy-to-fill removable reservoir with auto-metering, a permanent reusable filter, and a handful of convenience features — programmable delay brew, keep-warm, and auto shut-off. Owners who use it daily most often highlight its flexibility and consistent flavor; a number of them also report months or years of trouble-free use. This review walks through what the machine actually is, what owners repeatedly like and dislike, the build and safety considerations you should know, who it fits, and the checklist to run through before you buy.

What it is / first look

The Ninja CM371 is a fully automatic drip coffee machine that aims to replace both single-serve brewers and family-size drip pots. The listing classifies it as a drip coffee machine with four named brew styles — Classic, Rich, Over Ice, and Cold Brew — and eight sizes that cover everything from a small cup up to a full 12-cup carafe. It’s powered by a 1550-watt electrical supply, uses ground coffee (no pods required), and the primary carafe material listed is glass. The unit lists a removable water reservoir with auto-metering, a reusable permanent filter, and a few user-facing features like a keep-warm function and 24-hour delay brew.

The machine’s footprint is listed at 12.32" deep by 9.13" wide and 15.08" high, and the weight is 9 pounds. The exterior is described in the listing as a durable finish and the unit comes in black. Included components called out in the product facts are a 12-cup glass carafe, a permanent filter, and a Ninja Smart Scoop. The listing also highlights "Thermal Flavor Extraction" as the method it uses to manage flavor and temperature during brewing.

First visual and counter fit impressions

• The CM371 has a larger footprint than small single-serve machines; owners repeatedly call it "bigger" but manageable if you give it a dedicated spot on a coffee bar or countertop.
• Because the carafe is glass and the reservoir is removable, owners appreciate the straightforward, familiar look compared with pod machines.
• Color: the listing shows Black as the color option. Available images suggest only the black finish for this listing.

In daily use

Owner feedback strongly shapes the real-world picture here: the CM371 is repeatedly described as versatile and reliable for households that want one machine to handle single cups, travel mugs, and full carafes. Several owners note they use it multiple times per day and that performance and parts hold up under heavy use for months or years.

Brewing styles and flavor

• The listing specifies four brew styles: Classic, Rich, Over Ice, and Cold Brew. Owners repeatedly praise the Over Ice setting for producing bold iced coffee that isn’t watered down, and they report the Rich setting can yield noticeably fuller flavor than Classic.
• Owners measuring brew temperatures report extraction temperatures in the neighborhood of 193–203°F, which they cite when describing how "hot" the coffee comes out.
• Several owners liken the machine’s multi-stream brew action to an automatic pourover, saying it produces consistent flavor whether brewing a single cup or a full carafe.

Size options, single-serve to family pot

• The product facts list eight brew sizes that range from a small cup to an XL travel-size and include quarter, half, and full carafe options; owners value this flexibility for mixed households and entertaining.
• For single-cup users, people note the machine is faster and cleaner than pulling a pot and still gives a full-extraction taste resembling a pot rather than a weak one-cup pour.
• For multi-cup needs, owners report consistent results for half and full carafe pours; one reviewer explicitly called out comfortable performance brewing multiple full pots over several days without failure.

Reservoir, fill and cleanup

• The listing highlights a removable reservoir with auto-metering, and owner feedback confirms that the reservoir is easy to lift and fill and that auto-metering removes some guesswork when switching sizes.
• Owners say the permanent reusable filter is easy to remove and clean; several mention that removable parts are dishwasher friendly (owner observations) and that grounds are straightforward to discard.
• When a descale indicator appears, owners report using a vinegar+water cycle to clear buildup as a practical maintenance solution.

Extras owners mention

• The listing calls out a permanent filter and Smart Scoop; owners also commonly reference a frother wand and say it creates smooth foam for lattes and hot cocoa. The frother is present in several owner reports as a valued add-on.
• Owners highlight a flip-up platform that accommodates travel mugs and larger tumblers when needed, and a drip-stop feature that allows pouring mid-brew without making a mess.
• Noise and beeping: a few owners describe the machine as reasonably quiet and note a done beep.

Materials & build quality

Specs list the carafe material as glass and the product facts describe the exterior as a durable finish. The listing also calls out a permanent (reusable) filter and a removable water reservoir as build features.

Owner feedback fills in the lived detail: several users who have had the machine for months to years report no cracking, rust, or mechanical slowdown. One long-term owner specifically said their previous unit lasted eight years before the reservoir began leaking and they replaced it with the same model; others report heavy daily use for 8+ months with no material changes. These patterns indicate a reasonable expectation of solid day-to-day build for many users, while isolated reliability issues show up in the long tail of ownership experiences.

There are a few consistent notes to be aware of when it comes to materials and finish:

• Plastic presence: multiple owners mention a noticeable amount of plastic in the machine's construction and an initial plastic smell when unboxing. Owners report that running several water-only cycles (as the manufacturer instructions suggest) diminishes and usually eliminates the odor.
• Glass carafe: the carafe is listed as glass, which owners like for appearance and taste neutrality; a few buyers point out you’ll need a bottle brush to clean the inside because hand access is limited.
• Included parts: the listing explicitly lists the 12-cup glass carafe, permanent filter, and Ninja Smart Scoop among included components. Owners also describe a frother wand attachment as part of what they received or used, though that specific component isn’t called out in every product-facts list included in the listing screenshots.

Safety considerations

The listing includes several built-in safety and convenience features that affect everyday use: Auto Shut-Off, Programmable controls, Removable Tank, and Timer. Those are positive features for safety by design — auto shut-off mitigates overheating when you forget to turn the unit off, and a removable reservoir makes filling safer than carrying the entire machine to a sink.

Owner comments bring up a few practical safety and maintenance points:

• Standing water and cleaning: several owners posted about a small "bubble" of water in the bottom of the reservoir that can retain moisture. That has led to owners advising regular drying, keeping the reservoir lid open between uses, and occasionally pressing a spring or draining that spot to avoid buildup. Some buyers specifically researched "algae" concerns and took extra care to keep that area dry. These are cleaning practices to adopt if you plan to leave water in the machine overnight.
• Initial plastic odor: some owners noticed a plastic smell out of the box and ran multiple water cycles to deal with it. While odor is a nuisance more than a safety failure, follow the listing's setup steps (run water cycles) and manufacturer instructions before brewing coffee.
• Drip when removing carafe: owners mention you may see a drip or two when pulling out a full carafe. This is a minor operational nuisance rather than a major safety hazard, but worth being careful with hot liquid.
• Descale and maintenance: owners recommend running vinegar/water descale cycles when the descale indicator lights up; keeping the machine maintained limits performance issues and potential clogging that could cause spills or uneven brewing.

Finally, the listing does not list any smart-home compatibility — it’s not a connected device — so remote control or scheduled start beyond the unit’s 24-hour delay brew option is not available. Verify the latest manufacturer documentation for current safety and maintenance guidance before regular use.

Who this is for / who should skip

The CM371 suits cooks and households who want a single, versatile brewer that replaces both a pod-style single-serve machine and a family-size drip pot. Owner comments consistently point to these use cases:

Great fit for

• Households that need multiple serving sizes daily: owners praise the single-cup convenience and the ability to make half or full carafes for guests.
• People who prefer ground coffee and want to avoid pods: the listing explicitly notes "No Pods Required" and owners emphasize the flexibility to use different beans and grinds.
• Iced-coffee lovers: the Over Ice and Cold Brew modes are repeatedly cited by owners as producing strong, flavorful iced coffee without dilution.
• Hands-off operators: users who want an automatic pour-over style extraction without manual pourover technique will appreciate the programmable features and auto-metering reservoir.

Who should skip or consider alternatives

• Buyers who need espresso-level pressure: this is a drip-style brewer, not an espresso machine. If you specifically need espresso, this is not the right device.
• Extremely tight-cabinet kitchens: the unit is 15.08" tall and some owners recommend pulling it forward from under cabinets to access the brew basket — check the listed height and your underside cabinet clearance.
• If you never want to deal with any plastic smell: a few owners reported an initial plastic odor that required several water cycles to dissipate. If that would be a deal-breaker, consider machines with a different construction profile or verify the current listing/manufacturer guidance.

Verdict

For many home cooks and coffee drinkers, the Ninja Hot & Iced XL (CM371) is a practical all-in-one brewer: it covers single cups through a 12-cup glass carafe, offers cold-brew and over-ice settings for iced coffee, and includes convenient features like a removable reservoir, permanent filter, keep-warm, and a 24-hour delay brew. Owner patterns show repeated praise for flavor consistency, the iced coffee capability, and long stretches of reliable daily use. A number of owners also report months or years of trouble-free service; isolated long-term failures exist in the ownership record but are not the dominant signal.

On the flip side, plan for some initial break-in: owners commonly report a noticeable plastic smell right out of the box that fades after running water cycles. Also factor in routine cleaning practices around the reservoir to avoid retained water. If you want one machine that handles everything from iced coffee in a travel mug to a hot 12-cup carafe for company, this listing-backed combination of features and the strong owner sentiment for flavor and longevity makes the CM371 a practical mid- to upper-range countertop choice.

Check before you buy

• Confirm counter space and cabinet clearance against the listed dimensions: 12.32" D x 9.13" W x 15.08" H and a 9-pound unit weight.
• Decide whether a glass carafe fits your usage; the listing specifies the carafe material as glass and owners note it looks and tastes neutral but can be harder to reach inside for hand cleaning.
• Plan to run initial water-only cycles to reduce any plastic odor (owners recommend this practice).
• Verify you have an outlet that can supply 1550 watts and that you’re comfortable with a non-smart (not connected) brewer — the listing marks it as not smart home compatible.
• Accept that maintenance includes occasional descaling and attention to the reservoir bubble that some owners empty or leave open between uses to reduce retained moisture.
• Confirm included components against the current listing: product facts list a 12-cup glass carafe, permanent filter, and Ninja Smart Scoop; owner reports frequently mention a frother wand but check the current listing to confirm package contents.

Quick ownership signals: owners consistently praise the machine’s flavor, iced coffee performance, removable reservoir, and multi-size flexibility. A minority of long-term reports note possible reservoir leaks after many years or an initial plastic odor; routine cleaning and following manufacturer setup guidance are the commonly shared mitigations.
