The Smart Solution for Small Item Laundry Care
In modern life, hygiene has become more important than ever—especially when it comes to our most personal garments. Yet many people still wash their underwear and socks together in the same load, either by hand or in a full-sized washing machine. This common practice can lead to cross-contamination, as socks often carry fungi and bacteria that should not come into contact with intimate apparel.
Enter the Dual-Cup Washing Machine—a thoughtfully designed appliance that revolutionizes how we clean small personal items. With its innovative dual-tub design, this compact washer lets you wash underwear and socks separately but simultaneously, saving time while promoting better hygiene.
Why Separate Washing Matters
Before diving into the product features, it’s worth understanding why keeping underwear and socks separate during washing is important for your health.
Socks spend all day in shoes, absorbing sweat and coming into contact with floors and various surfaces. They commonly harbor fungi, including those that cause athlete’s foot. Underwear, on the other hand, comes into contact with sensitive areas and requires gentle, hygienic cleaning.
When washed together, bacteria and fungi from socks can transfer to underwear, potentially leading to infections or skin irritations. The Dual-Cup Washing Machine solves this problem elegantly with its two independent washing cups—one designated for underwear, the other for socks.

How to Use the Dual-Cup Washing Machine
Using this appliance correctly ensures optimal cleaning performance and extends its lifespan. Follow these step-by-step instructions:
Step 1: Initial Setup
Upon receiving your Dual-Cup Washing Machine, immediately tighten both cups onto the base. During shipping, vibration may loosen the cups. Tightening them first prevents leakage during first use.
Step 2: Load Your Laundry
Place dirty items into the cups:
- Left cup: Underwear (maximum 2 pieces)
- Right cup: Socks (maximum 4 pairs)
Important: Never mix underwear and socks in the same cup. The dual-cup design exists specifically to maintain separation.
Step 3: Add Detergent and Water
- Add appropriate amount of laundry detergent or specialized underwear wash
- Pour water until items are fully submerged
- Close both cup lids securely
- Water temperature should not exceed 55°C
Step 4: Power On and Select Mode
- Connect the adapter to the DC port on the base
- Plug the adapter into a power outlet
- The digital screens will show scrolling lights, indicating standby mode
Operating the machine:
- Long press for 3 seconds to power on or off
- Two washing modes available:
| Mode | Cycle Pattern | Duration | Display |
| P1 | 5 seconds forward, 5 seconds reverse | 5 minutes | “P1” on screen |
| P2 | 10 seconds forward, 10 seconds reverse | 10 minutes | “P2” on screen |
Choose P1 for lighter soils or delicate items, P2 for deeper cleaning when needed.
Step 5: Important Safety Notes During Operation
- Ensure cups are tightly secured before starting, or water may splash out
- Do not manually stop the pulsator while it’s rotating—this can damage the mechanism
- Do not overload beyond recommended capacity
Step 6: After Washing Completes
- When the cycle ends, unplug the device
- Invert each cup and unscrew to remove
- Rinse away soap bubbles from cups and items
- Hang items to dry normally
Step 7: Cleaning the Machine
- Transparent cups: Rinse directly with water
- Base unit: Wipe with a dry towel only—never rinse or immerse the base in water
- After cleaning, place cups on the drying rack or store in a safe place for next use
Special note: If you remove the cups from the base, never start the machine. Operating without cups attached can cause damage.
