Our take
The Sanyo EM-S6588S is a distinct 1.0-cu.-ft. solo countertop model. Its exact service manual identifies the model, black color, touch controls and 120/60/U3 supply. The product sheet adds 1,000-W output, ten power levels, a 12 3/8-inch glass turntable, child lock, a black cabinet and stainless door/front, plus eight direct-access keys. That makes it a measured medium-small option between the smaller 0.7-cu.-ft. models and larger Panasonic or Whirlpool cavities. The sources do not establish sensor cooking or a trim-kit route, and the old title's generic stainless wording should not be used to label the whole cabinet stainless.
A one-cubic-foot countertop choice for users who want a measured 12 3/8-inch tray and direct controls without relying on unverified finish or accessory claims..
Avoid it if you need more than 1.0 cu. ft., a turntable larger than 12 3/8 inches, confirmed sensor cooking, or a documented cabinet kit.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The service manual resolves the exact EM-S6588S model and U.S. 120/60 supply.
- A model-specific product sheet lists a 12 3/8-inch glass tray and 1,000-W output.
- Eight direct-access keys, ten power levels and weight/time defrost are documented controls.
What to weigh up
- The 1.0-cu.-ft. cavity is smaller than 1.2-, 1.4- and 2.2-cu.-ft. alternatives.
- No reviewed exact-model source confirms sensor cooking or optional trim-kit compatibility.
- The cabinet is listed black with a stainless door/front, not as all stainless steel.

What the features mean for you
Preserve the full EM-S6588S identity
Sanyo's service manual names EM-S6588S and gives its U.S. destination, black color and 1.0-cu.-ft. solo cavity. The exact model sheet uses the same full code. Keep it distinct from other EM-S family products because a shared prefix does not demonstrate the same capacity, finish or feature set. The source title calls the body stainless steel, but the exact product sheet separates a black cabinet from a stainless door color. That more specific record supports the practical finish description used here. Use the appliance label to confirm the final S suffix if a replacement or parts listing truncates it.
Match dishes against the 12 3/8-inch tray
The exact-model sheet gives a 12 3/8-inch glass turntable and an approximate exterior width of 20.19 inches. The 1.0-cu.-ft. cavity is a broad capacity measure, while the tray diameter says more about the base of a round dish that can rotate. A rectangular plate may require a separate cavity check. Measure the items you use most often and compare them with the tray before buying; do not assume that any plate smaller than the cavity's outside width will fit. The smaller volume can be a sensible fit for everyday plates and bowls while remaining less spacious than the 1.2-cu.-ft. Panasonic or 2.2-cu.-ft. Whirlpool.
Compare the stated output and controls
The model-specific product sheet lists 1,000 watts, ten power levels and weight/time defrost. It also identifies eight direct-access keys for popular foods, which give another route besides entering every cycle manually. These are documented control options rather than a promise about a particular cooking time. The checked source set does not establish humidity-sensor cooking; the presence of direct keys is not the same as sensor adjustment. If sensor automation is important, compare Panasonic NN-SN65KB or GE JES1460DNBB, whose manuals explicitly describe sensor operation. If you mostly use fixed times and power levels, the Sanyo's control description may be sufficient.
Use the U.S. supply fact but check the exact outlet
The service manual lists V/Hz/plug as 120/60/U3, and the original owner manual specification search likewise identifies AC 120 V, 60 Hz. That supports the exact model's U.S.-supply match in the finder. The sources do not give an amperage value in the saved product sheet, so this profile does not turn voltage/frequency into a circuit rating. Check the appliance plate, grounded outlet and installation instructions for your actual unit. Supply compatibility addresses voltage and frequency only; plug shape, grounding and branch-circuit capacity still deserve verification.
Keep preset and sensor claims separate
The source sheet names direct food keys, defrost, child lock and ten power levels; the service manual calls the control panel touch-operated. Neither source in the reviewed packet documents a humidity sensor or a sensor-cook mode. The match profile therefore leaves sensorCooking null, rather than interpreting convenience buttons as a sensor. That distinction is important when comparing this Sanyo with Panasonic's named Genius Sensor feature or GE's humidity-sensor manual section. Buyers who want straightforward time, level and preset operation can consider the listed controls, while those who require sensor cooking should select a model with explicit documentation.
Do not assume a trim kit or commercial rating
The exact product sheet labels this model countertop, and the reviewed documents do not name a cabinet trim kit or a foodservice classification. Keep both attributes unknown. A countertop product can be placed on a suitable stable surface with clear vents, but a trim kit would need a model-specific compatibility record and cabinet opening instructions. Likewise, a household-looking product name or the word solo does not establish a commercial approval. If your installation is inside cabinetry or in a shared-use kitchen, ask for the correct manufacturer documentation rather than borrowing a kit or duty claim from a different Sanyo model.
Use an exact-model search for the current offer
The historical Amazon ASIN did not establish a current exact product offer, so the affiliate destination searches the complete EM-S6588S code and contains buyershortlists-20. Confirm the suffix, the black cabinet/stainless front arrangement and the 12 3/8-inch tray in any present result. The product sheet's review area is not used to make buyer-review claims. Neither the frozen title nor historical ASIN supplies current price, availability, seller condition or sales evidence. The exact Sanyo manuals support model facts; the tagged search is a shopping route that lets a visitor inspect current offers independently.
What else to compare
Panasonic NN-SN65KB increases the cavity to 1.2 cu. ft. and adds inverter/Genius Sensor controls, but its manual specifies a separate 20-A circuit and does not confirm a kit for the KB suffix. Sharp R-420LW grows to 1.4 cu. ft., lists a 14 1/8-inch tray and documents the white RK-40W24 option. Sanyo is the option with a 12 3/8-inch tray and simpler direct controls.
Before you buy
What is the exact capacity and tray size?
The Sanyo sources identify a 1.0-cu.-ft. cavity and a 12 3/8-inch glass turntable.
What supply does the service manual list?
It identifies a U.S. 120/60/U3 supply; confirm the exact unit plate and grounded outlet.
Is the entire cabinet stainless steel?
The exact product sheet lists a black cabinet with a stainless-steel door, so an all-stainless claim is not supported.
Does it have sensor cooking?
The reviewed manual and model sheet do not confirm sensor cooking; direct-access keys are a separate feature.
Can I install it with a trim kit?
No exact-model trim kit is listed in the reviewed sources, so cabinet compatibility remains unknown.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
Choose EM-S6588S when its 1.0-cu.-ft. cavity, measured tray and straightforward controls suit your dishes. Keep its black cabinet/stainless front description precise, and treat sensor and trim-kit compatibility as unconfirmed.
