Cuisinart Supreme Super 600 SB-5600 Blender review

The Cuisinart Supreme Super 600 SB-5600 is an earlier full-size blender built around one nominal 60-ounce heavy glass jar. Cuisinart’s exact U.S. listing names the model SB-5600, a Brushed Stainless finish, a 600-watt high-torque motor and a 2-ounce measured pour lid; the listing marks it discontinued and out of stock. This review is useful for comparing an identified used machine or understanding the product family, not as evidence of new retail stock.

More jar than a small countertop unit, not a 64-ounce pitcher

The 60-ounce jar clears a 48-ounce minimum but not a strict 64-ounce family requirement. That number describes nominal jar capacity, not the safe finished volume for a foamy drink or hot mixture. The exact product page and booklet do not establish a numeric maximum-liquid or finished-batch line, so do not treat 60 ounces as a fill-to-the-rim recipe allowance. The jar is glass, with a widemouth opening, pour spout, lid and measured pour cap. Glass avoids a plastic pitcher, but it adds weight and requires care: the manual warns not to use a chipped or cracked jar and describes thermal-shock cautions around hot dishwashing and cold contents.

The included setup is a countertop jar, not a family of alternate containers. The exact page lists no personal cup or processor bowl. That makes the SB-5600 simpler to compare with the single-jar CB-9 and CBT-700 than with Cuisinart’s SmartPower Duet packages. If your must-have is a separate processor, the BFP-703 offers a different configuration, but its 40-ounce blender jar and three-cup processor bowl are separate setups, not added capacity.

Six-speed buttons do not mean six timed cycles

Cuisinart markets the controls as preprogrammed six-speed push buttons with LED indicators. Its booklet explains the speed buttons for Chop, Mix, Purée and Liquefy, then describes Pulse at any speed and a separate Ice Crush control. The manufacturer's six-speed language is the product’s control description, not a set of six timed recipes: the instructions show the user selecting a speed, changing it manually and stopping it. No timed smoothie or cleaning cycle is documented. Ice Crush itself operates in short pulses, so choose it for controlled bursts rather than expecting a hands-off countdown.

This is different from the CBT-700, whose booklet documents timed Smoothie and Ice Crush routines alongside Low/High/Pulse. The SB-5600 has a larger jar than that 56-ounce model and a 600-watt rating, but the rating is a maker specification, not a comparison test. The manual describes cyclonic blending action as Cuisinart’s design claim; it does not provide independent texture, durability or noise measurements. If choosing between these older machines, decide whether nominal 60-ounce glass capacity and several named manual speeds matter more than a smaller jar with timed routines. Neither choice establishes performance superiority.

Ice has a specific short-burst use

The booklet says the motor can crush ice without liquid and directs the user to activate Ice Crush in short pulses. Its recipe tips provide a concrete example of up to 10 standard ice cubes in the jar, pulsed until snow-like or coarser as desired. That is a documented ice plan; it is not permission for unrestricted frozen solids. The manual says not to add solid frozen foods except ice cubes or ½-inch frozen-fruit pieces. It also cautions against thermal shock, including loading very cold contents into a jar just removed from a hot dishwasher.

For hot work, remove the measured center lid to let steam escape. Boiling liquids should cool for five minutes before being added. Neither the exact page nor the manual gives a maximum hot-liquid amount, so a shopper who needs a published hot-fill capacity should treat this as unknown rather than infer one from the 60-ounce nominal jar. Keep the cover on during blending and follow the manual’s assembly sequence; the blade assembly, gasket and locking ring fit at the jar base, so it is important to inspect and correctly tighten the ring.

Separate parts add cleaning and used-unit checks

The glass jar may be placed upside down in the dishwasher. The cover and measured pour lid can go on the upper rack, and the locking ring is also listed for the upper rack. The blade assembly and gasket are removed and washed by hand; the sharp blade should not be disassembled. The base is wiped with a damp cloth and must not go in the dishwasher or be submerged. That routine is practical if the removable parts are kept complete, but it involves more disassembly than a single-serve vessel with an integrated blade base.

Cuisinart lists a limited three-year warranty for the original product. That term cannot establish remaining coverage or transfer on a used example. For a secondhand listing, check the model plate, glass for chips or cracks, locking ring, gasket, blade assembly, lid and measured cap, and confirm the motor base stops and starts as described before relying on it. The exact manufacturer page also lists a jar sealing gasket as a part; seeing a replacement part on that page does not mean the used package includes one.

Who should look for SB-5600?

Consider it as an earlier reference if you want a larger, nominal 60-ounce glass jar, a 600-watt manufacturer rating, manual push-button speed selection, Pulse and a dedicated pulsed ice control. It does not suit a 64-ounce minimum, a confirmed 60-ounce safe fill, a timed recipe-menu requirement or a shopper seeking a currently stocked new machine. The 40-ounce CB-9 is smaller and has a five-speed touchpad identity; the 56-ounce CBT-700 documents timed smoothie and ice routines; the 40-ounce BFP-703 adds a separate three-cup processor but not a larger blender jar. Those comparisons help determine what setup fits your tasks without turning discontinued listings into current purchase recommendations.
