FAQs: Everything About Buying & Using Sex Machines

Sex Machines

A sex machine is a motorized device designed to provide automated sexual stimulation (usually thrusting). Here is a summary of the most frequently asked questions regarding sex machines.

A sex machine is a mechanical or motorized device designed to simulate human sexual intercourse or provide targeted sexual stimulation. They offer hands-free, automated pleasure using controlled movements such as thrusting, suction, or vibration.

Sex machines are motorized, automated devices designed for hands-free or partner-assisted sexual stimulation. They primarily fall into five main categories, ranging from oscillating automated thrusting machines and saddles to interactive teledildonics.

Motorized Thrusting Machines: Automated devices designed to mimic the motion of sexual intercourse. They feature a motor that drives a dildo or masturbator back and forth at varying speeds and depths.
Grinding and Riding Machines: Stationary devices equipped with vibrating, rotating, or undulating bases. Users straddle or press against the machine, allowing for deep, rhythmic, hands-free stimulation of the clitoris, perineum, and surrounding areas.
Teledildonics (Smart Machines): These machines are defined by their connectivity rather than just their mechanical motion. They are equipped with Bluetooth or Wi-Fi. Users can control the speed and rhythm from anywhere in the world via a smartphone app.
Automated Masturbators (Strokers): Motorized sleeves that use internal mechanisms (such as suction, rolling, or vibrating motions) to simulate oral or penetrative sensations automatically.
Vacuum & Pump Machines: Automated or manual cylinders that fit over the penis or clitoris. They use air suction to draw blood into the erectile tissue, which increases sensitivity, causes engorgement, and can lead to intense arousal.

Couples seeking hands-free variety: Partners can use machines together, allowing them to focus entirely on intimacy and connection without the fatigue of manual exertion.
Solo enthusiasts: Perfect for anyone wanting deeply customized, rhythmic, and high-stamina stimulation for extended solo sessions.
People with physical limitations: Those dealing with chronic pain, joint issues, or disabilities can enjoy sexual fulfillment without the physical demands required by traditional positions.
Long-distance partners: Many modern devices (RX-15, Elves, Black Dragon, Black Evil, RX-5) have an app-enabled feature (like teledildonics) that allow a partner to control the machine’s rhythm and intensity remotely.
Power Seekers: Those who find standard handheld vibrators aren’t intense enough.
Kink and BDSM practitioners: Many machines can be incorporated into bondage or restraint play to add automatic, rhythmic sensation without relying on human energy.
Live streamers and content creators: A sex machine is more than just a toy—it is a professional-grade tool designed to increase engagement, boost revenue, better subscriber retention, and improve production quality.

Yes, when used correctly, sex machines are safe and effective tools for pleasure. Follow the key safety pillars:

Emergency Stop: Higher-end machines have a “kill switch” or a remote with an instant off button.
Keeping it Steady: To keep your machine from “walking” or tipping, always set it up on a flat, firm surface. If the motor’s power causes the machine to move around, you can use weights to anchor it for a smoother, safer experience.
Physical Limits: Unlike a partner, an automated device cannot sense resistance or discomfort. To prevent over-exertion or injury, always initiate play at the lowest speed setting and take breaks.
Lubrication: Use plenty of water-based lubricant to prevent tearing and abrasions.
Water Safety: Most motorized machines are not waterproof. If powered by a wall outlet, safely grounded.
Safety Tip: Ensure that hair, jewelry, loose clothing and skin are kept well away from the moving mechanical parts or gears to avoid pinching and entanglement.

Our sex machines are designed to be quite discreet, typically maximum operating between 38 and 60 dB. This noise level is generally comparable to a quiet ceiling fan, a low electric razor, or a standard indoor conversation, allowing them to be used in shared living spaces without disturbing others.

Pro-Tips for Discretion:

Surface Matters: Placing the machine on a thick mattress, rug, or carpet absorbs a lot of the mechanical vibrations, significantly reducing the overall noise.
Lubrication: Applying plenty of quality lubricant (like water-based or silicone-based) reduces friction against the toy, which keeps the operation much smoother and quieter.
Settings: The noise level will increase at higher speeds; running the machine at a moderate pace keeps it whisper-quiet.

Power and Control: Look for adjustable speed and depth controls. Powerful motor should be able to go from a slow, gentle pace to a high-speed rhythm—rather than just “low/med/high”—without stalling under pressure.
Stability: A heavier, robust frame (often made with steel components) will handle friction and resistance much better than lightweight plastic models, which may wobble.
Angle Adjustment: The machine should allow you to pivot, tilt, or lock the shaft at various angles so you can use it comfortably in multiple positions (e.g., lying on your back, on your stomach, or on all fours).
Attachment Compatibility: Check if the device is compatible with a wide range of standard toys or sleeves so you can switch out attachments.
Body-Safe Materials: Always check that the attachments are made from 100% medical-grade silicone, glass, or stainless steel. Avoid cheap, porous “jelly” toys, which can harbor bacteria and degrade over time.
Noise Level: Because of the mechanical parts involved, sex machines are rarely silent, but higher-end models use sound-dampening technology to keep the motor relatively quiet.

Yes, the rapid, repetitive motions of a machine create significantly more friction than manual stimulation or standard intercourse. Lube ensures smooth movement and protects delicate tissue.

Note: If you are using silicone attachments, use water-based lube to avoid damaging the toy.

Excessive depth can cause discomfort. Adjust your machine to the shortest stroke length and slowest speed before starting. Gradually increase these settings only after you’ve found a comfortable position.

Stroke length is the distance an attachment (such as a dildo) travels in one full thrust. Most of our machines offer adjustable depth for a personalized experience, though the Mini RX-5 features a fixed stroke.

The speed is fully adjustable, ranging from a very slow pace to faster than humanly possible. See the table below to compare power, depth, speed, and assembled weight across our lineup.

Maximum 280 thrusts per minute: RX-5
Maximum 300 thrusts per minute: FM19, FM18, Mini FM18, FM12, FM08, FM05, FM02
Maximum 320 thrusts per minute: RX-15, Black Dragon, Black Evil, Elves, Devil, Wearable, Slave Stool, Obedience Chair, Butterfly
Maximum 1200 thrusts per minute: FM07

Wired Control: Features a physical dial remote connected via a cable, but limited by the cord’s length.
Dual Control: Includes the wired dial plus a wireless remote with 18 built-in thrusting patterns. This makes it easier to stay in the moment during solo sessions or let a partner take the lead from across the room.

* Please note that the Wired Control cannot be upgraded to the Dual Control.

Standard: Features 2-in-1 wired and wireless speed dial control.
Professional: Includes all Standard features plus mobile app control, specifically designed for long-distance play with a partner.

Yes! All our machines come with absolutely everything you need to get started right out of the box. Your order includes the machine, the power supply, speed dial controller, and dildo attachment. All you need to provide is your favorite water-based lubricant!

All of the following machine models feature a powerful, quiet, and durable 120W, 300 N.cm high-torque motor: FM19, FM18, Mini FM18, FM12, FM08, FM05, FM02, RX-15, Black Dragon, Black Evil, Elves, Devil, Wearable, Slave Stool, Obedience Chair, Butterfly.

The FM07 is powered by an industrial-grade 200W servo motor. With 350 N.cm of high-torque performance, it delivers incredible strength and precision.

The Mini RX-5 features a refined 70W motor, making it the perfect choice for those seeking reliable, stable performance in a smaller footprint.

Yes. Our high-torque motors are rigorously tested to handle XL attachments up to 2.7 kg (6 lbs) without stalling. However, please note that the Mini RX-5 is not suitable for oversized toys.

Yes, you can use your existing Vac-U-Lock collection (such as Doc Johnson) with our machines! You will just need a special Vac-U-Lock machine adapter (sold separately) to attach them.

How it works: The adapter securely screws or locks into your machine’s shaft or extension rod, providing a standardized connection point for any Vac-U-Lock base.

Yes! You can easily use your favorite suction cup base dildos with our machines. All you need is a suction cup adapter (sold separately) to securely attach them.

Yes! While we recommend our specific double penetration model FM07, all our thrusting dildo machines (except the Mini RX-5) can support DP with our specialized adapter: ‘Quick Connect’ Dildo Doubler and Double Vac-U-Lock Dildo Adapter.

Our double-ended thrusting models (FM07, FM18, Mini FM18, FM19, RX-15) feature two reciprocating arms equipped with both a stroker and a dildo for synchronized pleasure. This allows both partners to receive penetration or stimulation at the exact same time, ensuring no one is left waiting their turn.

Plug-in powered for non-stop sessions.

Yes. We ship US, EU, AU, or UK plugs based on your destination country. Additionally, all our devices support universal voltage (100-240V), making them safe to use anywhere in the world.

Using your first sex machine comes down to taking it slow, using plenty of water-based lubricant, and experimenting to find what feels right for your body.

Follow these steps for a great experience:

Set the Stage: Place the machine on a flat, stable surface. If your machine has suction cups or a stand, ensure they are securely fastened. And checking the power source.
Attach Toy Attachment: Secure your chosen attachment into the machine’s connector (usually a “Quick-Connect” or R-Lock system).
Lubricate: Apply a generous amount of water-based lubricant to both yourself and the attachment.
Find Your Position: Get comfortable! You can use the machine while lying down, kneeling, or sitting, depending on the machine’s angle.
Start Slow: Always turn the machine on at the lowest speed first. Gradually increase the pace and depth as you get used to the rhythm.

The “Golden Rule” of Anal Play: If you are using a device internally (such as a dildo attachment or automatic stroker with a sleeve), it must have a flared base or lip. Never insert any object internally without a proper guard, as it can get stuck.

Our early videos use the manufacturer name “Dao Huan” because we hadn’t yet finalized our branding. We’ve since launched Lustti to create a unified identity and establish the brand recognition our products deserve.

Maintaining a sex machine involves regular cleaning of the attachments, proper lubrication, and mechanical upkeep. Always disconnect the power before cleaning.

Attachments: Always wash all toy attachments after every use with warm water and an unscented, antibacterial soap, or a dedicated Sex Toy Cleaner. Air-dry them completely (or use a lint-free paper towel). Store in a cool, dry place away from sunlight, and keep items separately to prevent sticking.
Machine: Wipe clean, dry immediately, and never submerge. Store in a dry, dust-free place. Avoid wrapping cables too tightly around the machine, as this can fray wires over time.
Maintenance: Please apply liquid lubricating oil to the moving parts periodically. This ensures smooth motor performance and prevents wear from prolonged or frequent operation.

Store your sex machine in a cool, dry, dark, and private location—such as the back of a closet, a high shelf, or a lockable case. Some models include a discreet bag for secure storage and easy transport.

* Please ensure it is completely clean and dry, and store materials separately to prevent them from melting or degrading over time.

A blinking light and hesitating motor usually indicate one of the following:

Please ensure the device is connected to a reliable power outlet. Double-check that the power cord and all connectors are firmly and securely plugged in. If the issue persists, please contact us for further assistance.
Minor hesitation at low speeds is normal. If the device has been used extensively, allow it to cool for 15 minutes. However, if the issue persists at high speeds, the motor may be worn; please contact us for warranty service.

Yes! Every machine comes with a 3-Year limited warranty. This covers any manufacturing defects related to the motor and internal electronics, not “wear and tear” or damage from improper use. To ensure your device is protected, please keep your proof of purchase.

Unlike many in the industry who offer limited one-year coverage (such as Lovense, Hismith, F-machine, or Cloud 9) or no warranty at all, we lead the way by providing the long-term protection and peace of mind you deserve.

Please note that for hygiene reasons, dildo attachments and toys are typically not covered under warranty once used.

It’s true that many machines share a similar external design, but the real difference lies under the hood. At AdultRepDao, we invest in high-torque motors, reinforced frames, and safety-certified electronics that cheaper competitors often skip. When you buy from us, you aren’t just buying the machine—you’re buying a comprehensive warranty, dedicated customer service, and the peace of mind that your device is built to last.

Yes. We use SSL encryption and are PCI-DSS compliant to ensure your data is protected. Never enter payment info on a site that starts with “http://” instead of “https://.”

It is the 3- or 4-digit security code on the back (or front for Amex) of your card. It proves that you have the physical card in your possession.

We do not store your full card number. We use “tokenization” via a payment processor so your actual data is never sitting on our store’s servers.

If your payment is being declined, here are the most common reasons:

Your payment was declined by your bank or card issuer. To protect your privacy, your card issuer or bank doesn’t tell PayPal why your card was declined. Contact your card issuer or bank for more information.
Your card details are outdated. Update the expiration date or billing address associated with your credit or debit card.
Your PayPal account is limited. Resolve a limitation placed on your account.
You need to go through a security check. To deliver a secure service, PayPal may ask you to confirm your identity. PayPal does this to make sure it’s you using the PayPal account.
You haven’t confirmed the email address associated with PayPal. Confirm your email address now.
You haven’t confirmed your bank account. You need to confirm your bank account before you can use it to make payments.
You may be required to confirm your card. If a “Confirm Card” link appears next to your card details, you’ll need to confirm this debit or credit card before using it with PayPal. This step helps to make sure that the card is valid and belongs to you.
Your bank’s fraud detection system blocking a large or unusual purchase.

If none of the above apply or if you continue having issues with your payment, please contact us or change your payment method. You can add a debit or credit card or add a bank account.

This is a “payment authorization.” If the order failed, the bank will usually release these funds within 3–7 business days. No money has actually been moved.

Your order status will remain as “Processing” while it is being prepared and in transit. We manually update orders to “Completed” once delivery is confirmed and you have verified that everything is in order.

Don’t be concerned—tracking gaps are common. This usually means your package is in transit between countries or currently undergoing customs inspection. Scans will resume once it arrives at the next destination hub.

A signature is not strictly required, though we recommend being present to receive your order to ensure safe delivery.

The carrier may leave the package in a secure location at his discretion, such as a leasing office or porch. Otherwise, the carrier will leave a notice with instructions for rescheduling or pickup.

Return & Refund & Cancellation

Here are the answers to our most frequently asked questions regarding hassle-free returns and refunds.

Returns are accepted within 7 days of delivery, provided the item is unopened and the original factory seal or shrink-wrap remains intact. For hygiene reasons, we cannot accept returns on opened products, even if they have not been used.

* Please note that the customer is responsible for return shipping costs for change-of-mind returns.

For health and safety reasons, sex toys are considered intimate hygiene products. Once the packaging is opened, we can no longer guarantee the item is sanitary. This policy protects all our customers by ensuring that every item we sell is 100% brand new and never handled by another person.

We appreciate your understanding in helping us maintain our high standards.

We provide detailed descriptions, dimensions, and material lists for every product to help you make an informed choice. However, we cannot offer refunds based on personal preference, “climax results,” or dissatisfaction with the product’s power/sensation once the seal is broken.

If your sex machine has a technical fault or is not functioning as described, please contact us for a replacement under our warranty policy.

We’re sorry your machine isn’t performing as it should! Please follow these steps to get things back on track:

Check the Basics: Ensure all power cables are firmly connected to both the wall and the machine, and that any remote batteries are fresh.
Document the Issue: If the problem persists, take a short video of the machine’s behavior.
Contact Support: Email us at info@adultrepdao.com with your order number and the video. All our machines are covered by a 3-Year Warranty, and we will prioritize a repair or replacement for you.

Once we receive and inspect your unopened return, we will process your refund within 3 business days. The funds will be credited back to your original payment method.

Refund typically takes 3–5 business days to show in your account after we’ve issued it, depending on your bank or card provider. You’ll receive a confirmation email the moment it’s processed.

* Please note: Refunds are only issued for unopened items in their original packaging or for defective products verified by our technical team.

If you are returning an unopened item because you changed your mind, you are responsible for the return shipping costs. If the item is being returned because it is defective or we sent the wrong item, we will provide a pre-paid shipping label.

Your privacy is our priority. Any return shipping labels provided by us will use our discreet business name and will not mention “sex toys” or “adult products” on the exterior of the package.

We process orders within 24 hours to ensure fast delivery! You can cancel your order as long as it hasn’t been processed by our warehouse. Please contact us immediately with your order number. Once an order has been shipped, it can no longer be cancelled.
