Silonn SLICM57B-US sphere ice maker review

The Silonn SLICM57B-US is a countertop sphere-ice maker for people who want large, round pieces for a drink rather than a bin of small bullets or chewable nuggets. Silonn says the machine makes four two-inch spheres in about 35 minutes and can produce up to 144 spheres a day. Those are manufacturer claims, not a measured home-output guarantee; the page does not tie the daily figure to a room or water temperature. Its strongest practical distinction is that the exact listing describes both manual filling and an included hose kit for automatic water supply.

Sphere ice is the buying reason

This machine is built around one large format: four solid-core spheres, each listed at two inches, per batch. Silonn describes them as clear and slow-melting. The page’s description explains the intended use—keeping a drink cold without adding a handful of small pieces—but it is not an independent clarity or melt-rate test. If you prefer a crunchy, chewable texture, use the finder’s nugget option instead; this is a different kind of ice and a different appliance routine.

The 35-minute batch claim is more useful for planning than the headline maximum. Four spheres per cycle gives a concrete unit to collect, while the page’s “up to 144 a day” ceiling assumes repeated operation and does not state the conditions behind it. It does not promise a particular number in a warm kitchen. The specification table also calls the machine’s capacity 22 pounds without explaining whether that means a daily rate or the amount held in the basket. This guide therefore keeps pounds per day and stored ice weight unknown. Do not compare “22 pounds” directly with a model whose separate basket or daily output is clearly labeled.

Two water routes, one important installation check

The exact product page says you can add water manually or connect the included hose kit for automatic filling and continuous supply. That is a real choice: manual filling avoids routing a hose to the machine, while the hose option can reduce repeated refills if your counter is near a suitable water source. Silonn also says a water filter can be attached to that route and recommends purified or filtered water for clearer spheres. The listing does not say a filter is included, so treat it as a separate compatibility and purchase question rather than part of the box.

The dual-fill capability is useful only if the installation suits your kitchen. This is a 41.4-pound appliance, and the published dimensions conflict: the descriptive copy gives height, width and depth in one order, while the specification table labels a different depth/height arrangement. Because the axes disagree, strict width, depth and height matching is not safe. If the maker’s stated hose feed is essential, the model can satisfy that requirement; if a tight cabinet opening is essential, wait for an exact manual or manufacturer clarification before assuming it fits.

Cleaning exists; the full routine is not documented here

The listing says holding ON for three seconds starts self-cleaning and also refers to a hands-on manual-cleaning option. It gives no cleaning-cycle duration or step-by-step care instructions in the saved exact-page information. A shopper who simply wants a documented self-clean function can select that option. Someone requiring a maximum cycle time, a particular descaling procedure or a weekly maintenance schedule should not infer those details from the three-second activation instruction. Starting a program is not the same as knowing how long it runs or what components need separate cleaning.

The status panel is described as showing ice-making progress, insufficient water and a full basket. That gives the owner basic state cues, but it does not establish basket weight or the number of spheres the bin holds. The item is not described as a freezer, so move collected ice to a freezer if you need to keep it frozen between uses; do not assume the appliance preserves a finished batch.

Which questionnaire choices it can meet

SLICM57B-US can match a sphere-ice request, a minimum of four spheres per batch, up to 140 spheres per day without a specified temperature condition, and either manual refill or the documented hose-fed option. Those decisions all fit the same sphere-making system, though the refill answer selects one of two supported water routes. A request for 145 spheres a day exceeds the maker’s stated 144 ceiling. A warm-condition output requirement, a 22-pound basket, or an axis-specific counter limit should be rejected because the page does not verify those facts. Likewise, a strict cleaning-time maximum cannot be matched from the activation description alone.

If your main goal is soft nugget ice instead of round pieces, compare the separately reviewed Silonn SLIM24B-US; its page documents a nugget maker, not this sphere format. For strict dimensions or care instructions, choose a model with an exact manual and clearly labeled axes rather than treating an unresolved specification as a close-enough fit.

Availability and bottom line

The exact Silonn page showed SLICM57B-US sold out in the October 26, 2026 capture. Stock can change, so check the live exact-model listing before planning around it and search by the complete code “Silonn SLICM57B-US.” Do not substitute a similarly titled sphere machine if a particular water-fill or installation feature matters.

This model is an interesting fit for a deliberate sphere-ice routine: four large balls per advertised batch, manual or hose-fed water, and a self-clean mode. It is less suitable when you need a proven pounds-per-day figure, a rated basket capacity, a timed cleaning cycle or exact counter dimensions. Those gaps are meaningful, especially on a heavy appliance with a hose option. Keep the shopper decision to what Silonn actually documents, and confirm the unclear dimensions before giving up valuable counter space.
