The Silonn Ice Maker Countertop is a compact countertop ice maker for everyday drinks, best for households. The main drawback: basket is not refrigerated. We scored it 5.0 out of 5.
Silonn's compact ice maker turns out a batch of bullet ice every six minutes or so and needs no plumbing, but its 1.3 lb basket is not a freezer, so it keeps a drink station topped up rather than stockpiling ice for a party.
NoFussDeal rates the Silonn Ice Maker Countertop 5.0 out of 5 at $99.00. Last updated September 26, 2026.
The SLIM21 makes 9 bullet-shaped cubes in about 6 minutes, with a choice of small or large cubes. The first batch arrives soon after you switch it on, which is the main advantage over waiting for freezer trays.
Silonn rates daily production at up to 26 lbs, fed by a 1.2 L tank. The basket holds 1.3 lbs at a time, and the unit signals when the basket is full or the tank needs water.
An automatic cleaning cycle keeps the water path fresh. Remove the basket, add water and hold the CLEAN button for 5 seconds; the cycle takes 30 minutes.
At 8.7 x 11.4 x 11.6 inches and 13.7 lbs, it fits on a countertop, island or desk, and the sturdy handle makes it easy to move between rooms or take to an event.

Unpack the ice maker, remove any tape, and let it stand upright for a while before switching on so the refrigerant settles after transit.
Wipe the tank and basket, then run the self-cleaning cycle: remove the basket, add water, and hold CLEAN for 5 seconds.
Add clean drinking water to the 1.2 L tank, below the maximum line.
Turn the unit on and select small or large cubes.
The first batch of 9 cubes arrives in about 6 minutes. Use the scoop to empty the basket before it fills.
Top up the water when the add-water light comes on, and empty the basket when the ice-full light shows.
Yes: we score it 5.0 out of 5. The 30-minute self-cleaning cycle and carry handle make it easy to keep fresh and move around.
1.3 lb basket fills quickly. Basket is not refrigerated, so ice slowly melts.
Run the self-cleaning cycle regularly and after storage. Use clean drinking water only.
Start the machine a few hours early and move each full basket into freezer bags, so you build a supply instead of relying on the 1.3 lb basket.

Silonn Ice Maker Countertop, 9 Cubes Ready in 6 Mins
For You Reviews
The Silonn SLIM21 delivers what a countertop ice maker should: 9 bullet cubes in about 6 minutes, up to 26 lbs a day, and simple controls with small or large cube options and clear indicator lights. The 30-minute self-cleaning cycle and carry handle make it easy to keep fresh and move around. The limit is storage. The 1.3 lb basket fills quickly and is not refrigerated, so it suits keeping drinks topped up rather than stockpiling ice.
Buy the SLIM21 for quick, fuss-free ice on the counter. For big gatherings, run it ahead of time and freeze the batches, because the basket is a dispenser, not a store.
