Solo or Couples - the Machine Does Not Care, But Your Setup Should
A HiSmith sex machine works on a simple principle: consistent, motorised thrust at a speed and depth you control. What changes between solo and couples use is not the machine - it is the positioning, the attachment choice, and who has the remote. Get those three things right and the machine earns its place regardless of how many people are in the room.
The HiSmith Machines & Accessories range is built around the KlicLok attachment system, which is the reason solo-to-couples switchovers are practical rather than painful. Swapping a dildo for a stroker - or going from a slim anal attachment to something with more presence - takes about ten seconds. That flexibility is worth understanding before you spend anything.
HiSmith Sex Machine Solo Setup: Getting the Angle Right
Solo use comes down to one thing most first-timers underestimate: machine angle. The thrust axis on a HiSmith machine is horizontal by default, which works well for doggy-style positioning on all fours, or for lying face-down at the edge of a bed with the machine on the floor. But horizontal is not the only option, and for some positions - particularly lying on your back - a slight upward angle changes everything.
Most HiSmith machines have an adjustable arm or mount that lets you tilt the attachment. Spend five minutes dialling this in before you actually start. The difference between a good angle and a mediocre one is not subtle.
Attachment choice for solo use
For vaginal use solo, a mid-length curved dildo is the practical starting point. The HiSmith - 11" Silicone Black Curved Dildo (KlicLok) is worth considering if you want something that targets the anterior wall on the thrust stroke. Straight dildos work too, but they require more precise angle setup to hit the same spots.
For anal solo use, starting slim is the right call. The HiSmith - 7.5" Slim Silicone Anal Dildo (KlicLok) is built for machine use - tapered enough to take comfortably, with enough length that the thrust stroke does not run out of travel. Use plenty of lubricant and start at a low speed setting until you know how the machine feels at depth.
For male solo use, HiSmith makes the HiSmith - Thrusting Male Stroker (Suction Base / KlicLok), which mounts to the machine arm and handles the motion for you. Set it on a stable surface, adjust height, and the machine drives the stroker rather than you holding anything. If you want app control added to that, there is also a version with app connectivity for speed and pattern adjustments from your phone.
HiSmith Sex Machine Couples Setup: Who Controls What
Bringing a partner into a machine session changes the dynamic more than you might expect. The machine maintains a consistent rhythm that neither person has to sustain manually - which frees both people up. The receiving partner can focus entirely on sensation. The controlling partner can adjust speed, depth, and timing using the remote without interrupting what is happening.
This is genuinely different from one partner manually operating a toy. Fatigue is not a factor. The tempo does not drift. If anything, the challenge is remembering to actually vary the speed rather than leaving it at one setting and forgetting about it.
Positioning the machine for couples use
The most practical setup for couples is the machine on the bed behind the receiving partner, who is on all fours or lying face-down. The controlling partner sits or kneels beside the machine with the remote. This gives good sightlines, easy access to the remote, and lets the controlling partner add manual stimulation - using their hands or a separate toy - without being in an awkward position.
For face-up positioning, the machine works well at the foot of the bed on the floor, angled upward. The receiving partner lies back with hips at the bed edge. The controlling partner can stand or kneel to the side. This is less intuitive to set up but gives the controlling partner easier access to the front of the receiving partner's body.
Attachment choice for couples use
Couples tend to benefit from slightly longer attachments than solo users, purely because positioning is less precise when two people are involved. A longer shaft gives more room for adjustment. The HiSmith - 10" Silicone Aqua Awl Dildo (KlicLok) has the length and taper that suits variable positioning without needing constant angle tweaks.
If you want the machine to do more while the controlling partner adds stimulation elsewhere, the HiSmith - 8" Silicone Vibrating Pink and Purple Dildo (KlicLok) adds vibration to the thrust - useful if you want internal and external sensation happening simultaneously without a second toy in the mix.
For couples exploring double penetration, the HiSmith 7" Silicone Double Penetrator Dildo is built for machine use and handles both simultaneously. The geometry here requires more careful positioning setup, but the payoff is that the machine handles both without either partner managing separate toys.
KlicLok Makes Switching Mid-Session Practical
One thing that gets overlooked in most machine content is how useful the KlicLok system is when you are switching between uses in a single session. If you start with a dildo for one partner and want to switch to a stroker for the other, that swap takes seconds rather than minutes. The attachment clicks off, the new one clicks on, and you are back up and running.
This matters more in couples use than solo use, because mid-session changes are more likely when two people are involved and preferences shift. Keeping a second KlicLok attachment nearby rather than having to disconnect and reassemble anything is a small logistical win that adds up.

Speed and Stroke Settings: Solo vs Couples Defaults
Solo users generally start slower and build, because there is no external feedback loop - you adjust based on what you feel. Couples have a slight advantage here: the receiving partner can give real-time feedback and the controlling partner can respond immediately. In practice, couples tend to find their preferred speed faster than solo users simply because communication is direct.
A few practical defaults worth knowing:
- Start at around 30 to 40 percent of the machine's maximum speed and work up - most people find their comfortable range in the lower half of the dial, not at full throttle.
- Stroke depth matters as much as speed. A shorter stroke at higher speed feels different from a longer stroke at lower speed - both have their place depending on what the receiving partner wants.
- For anal use specifically, keep speed lower than you think you need and prioritise consistent rhythm over acceleration.
What the Machine Does Better Than Either Setup Alone
The honest case for a HiSmith machine in couples use is not that it replaces what partners do - it is that it removes the physical constraint of sustaining manual stimulation over time. One partner can give sustained, consistent internal stimulation via the machine while using their hands and attention elsewhere. The machine does not get tired, does not lose rhythm, and does not need to reposition.
Solo, the value is similar: you get the full experience of penetration without the physical effort of operating a toy manually, which means you can focus entirely on sensation rather than mechanics.
Neither setup is better in the abstract. It depends on what you are after. If you are buying a machine primarily for solo use but want couples capability later, the KlicLok system means you are not committed to one scenario - the attachment swap is what changes the experience.
The full HiSmith Machines & Accessories range covers both use cases well. If you are still working out which machine suits your setup, the broader Sex Machines collection is worth a look to compare form factors before committing. And if you are shopping with a partner in mind, the Sex Toys For Couples collection covers the wider picture beyond machine play.
The HiSmith - Spring Attachment (KlicLok) is also worth noting for couples who want some flex in the thrust - the spring absorbs some of the stroke force, which makes positioning less critical and gives the experience a slightly different feel than a rigid arm mount.

Frequently Asked Questions
Can you use a HiSmith sex machine with a partner?
Yes, and it works well. One partner can control the speed and stroke length via the remote or app while the other receives. The machine holds a consistent rhythm better than a human hand, which is actually the point. Positioning the machine on a bed or floor surface and using a longer KlicLok dildo gives both partners more flexibility in where they sit or kneel relative to the machine.
What is KlicLok and why does it matter for couples use?
KlicLok is HiSmith's quick-release attachment system built into their machines. It lets you swap dildos, strokers, and other attachments in seconds without tools. For couples, this matters because you might want to switch attachments mid-session - going from a slim anal dildo to something with more girth, or swapping in a stroker for the other partner - without killing the mood fumbling with connectors.
What is the best HiSmith attachment for couples use?
It depends on what you are both after. For vaginal penetration with the receiving partner on top or on all fours, a curved dildo like the HiSmith 11-inch Silicone Black Curved Dildo gives good G-spot contact at the right angle. For the giving partner to use on someone else without operating the machine themselves, a straight mid-length dildo with a realistic feel tends to be easier to direct. The KlicLok system means you can test a few without committing to one permanently.
Does a HiSmith machine work for male solo use?
Yes. HiSmith makes dedicated stroker attachments with KlicLok connectors, including a thrusting male stroker that mounts directly to the machine arm. You set the machine on a surface, insert the stroker attachment, and let the machine do the work rather than holding anything yourself. Speed and stroke depth are adjustable via the included remote.
