What the HiSmith Accessory System Actually Gives You
If you have already bought a HiSmith machine - or you are close to pulling the trigger - the accessory ecosystem is worth understanding properly before you spend another dollar. This is a genuine hismith sex machine accessories guide, not a list of things to upsell you on. Some additions are genuinely useful. Others are nice to have. A couple are only relevant for specific use cases.
The short version: HiSmith machines use a system called KlicLok, which is a proprietary quick-release connector built into the machine's drive arm. Attachments that carry the KlicLok designation snap on and off in seconds. This means you can switch from a slim anal dildo to a larger textured dildo to a stroker sleeve without any tools, without disassembling anything, and without a lot of fuss.
That modularity is the whole point of owning a HiSmith. Browse the full HiSmith Machines & Accessories range to see how the ecosystem fits together.
Understanding KlicLok: The Attachment System Behind Every HiSmith Accessory
KlicLok is not a separate brand or a third-party standard. It is HiSmith's own quick-release connector, built into their machines and replicated on the base of every compatible attachment. When you see "(KlicLok)" in a product title, that means the attachment has the matching connector and will mount directly onto any current HiSmith machine.
The mechanism itself is straightforward - a push-in twist-lock that takes about two seconds to engage and one second to release. There is no play or wobble once locked in. At the stroke speeds these machines run at, a loose attachment would be immediately noticeable, so the fit needs to be solid, and it is.
If you already own dildos with suction cups that you like, the HiSmith - 4.5" Red Suction Cup Adaptor (KlicLok) bridges that gap. It mounts onto the machine via KlicLok, then accepts any standard suction-cup dildo. It is one of the more practical accessories in the range because it doubles what you can use with the machine without committing to an entirely new attachment library.
HiSmith Sex Machine Accessories Guide: Dildos by Use Case
The dildo range covers a lot of ground in terms of size, shape, and intended use. Rather than listing everything, it makes more sense to break it down by what you are actually trying to achieve.
Vaginal Use - Realistic and Textured Options
For internal vaginal stimulation, the HiSmith - 10" Silicone Aqua Awl Dildo (KlicLok) is a solid all-rounder. The tapered tip works well for machine use because it allows easy entry at lower stroke depths before the full girth comes into play. Silicone is the right material for this - body-safe, easy to clean, and it does not degrade with repeated use the way some other materials do.
If you want something with added stimulation, the HiSmith - 8" Silicone Vibrating Pink and Purple Dildo (KlicLok) adds a vibration function on top of the machine's thrusting. That combination - thrusting from the machine plus localised vibration from the attachment - is more than the sum of its parts for a lot of users.
Size Play and Stretch
HiSmith makes no attempt to pretend their larger attachments are for everyone, which is honest. The HiSmith - 9.5" Silicone Purple and Blue Monster Dildo (KlicLok) and the HiSmith - 8.5" Silicone Golden Monster Dildo (KlicLok) are both designed with significant girth. If that is what you are looking for, the machine format suits this kind of play well because you control depth and speed independently rather than relying on manual effort.
At the far end of the scale, the HiSmith - 11.8" Silicone Dildo (KlicLok) is there for users who know what they want from something that size. Stroke depth on the machine is adjustable, so you are not forced to use the full length - that is worth keeping in mind when people assume a 11-inch attachment is only for experienced users who go the full distance.
Curved and Targeted Stimulation
The HiSmith - 11" Silicone Black Curved Dildo (KlicLok) is the attachment to consider if G-spot or prostate targeting is part of your plan. Machine-driven thrusting with a curved dildo produces a different sensation than manual use of the same toy - the rhythm is more consistent and the angle stays locked in rather than shifting with fatigue or repositioning.
Anal Attachments - What is Different and Why It Matters
Anal use with a machine requires a different approach to selection than vaginal use. The rectum does not self-lubricate, curves differently, and has a lower tolerance for aggressive entry. HiSmith's dedicated anal attachments reflect this.
The HiSmith - 7.5" Slim Silicone Anal Dildo (KlicLok) and the HiSmith - 7" Veined Slim Silicone Anal Dildo (KlicLok) are both designed with narrower profiles than the vaginal range. The veined version adds texture that works well at lower stroke speeds, where the movement amplifies surface detail rather than overwhelming it.
With anal machine use specifically, starting at lower depth settings and slower stroke speeds is not a suggestion - it is just how the anatomy works. Both of these attachments are designed with that in mind, which is why the slimmer profile is deliberate rather than a budget compromise.
HiSmith Stroker Attachments: Machine Use for Penis Owners
The stroker side of the Sex Machine Accessories range is smaller than the dildo range, but the options that exist are well thought out. The machine drives the stroker sleeve back and forth, which produces a fundamentally different sensation to a handheld stroker - the rhythm is mechanical, consistent, and does not tire out.
The HiSmith - Thrusting Male Stroker (Suction Base / KlicLok) is the straightforward option here. It mounts via KlicLok and includes a suction base, which means it can also be used freestanding if needed. It is a practical dual-use design.
For something with more going on, the HiSmith - Rotating Stroker with Black Case (KlicLok) adds rotation to the thrusting action. That combination is noticeably different to a standard linear stroker - the rotating sleeve creates a sensation that no handheld toy replicates particularly well. The case also makes storage and travel more straightforward, which is a practical detail that matters more than it sounds.
There is also an app-enabled version - the HiSmith - Thrusting Male Stroker (Suction Base / KlicLok and App) - if remote or synced control is relevant to how you plan to use it.
Specialist Attachments Worth Knowing About
Double Penetration
The Hismith 7" Silicone Double Penetrator Dildo is designed for simultaneous vaginal and anal stimulation. Used on a machine, it delivers both with a single thrusting motion. Setup requires more attention to positioning than a single-entry attachment, but for users who want DP without a partner, the machine format is about as reliable as it gets.
Going Larger
The Hismith 12.4" Penis Super Size Dong sits at the extreme end of the range. At that size, the machine's depth and speed controls do most of the work in making it usable - the adjustability that makes HiSmith machines worth the investment becomes very obvious when you are working with something in this size bracket.
Matching Accessories to Your Machine
If you are still deciding on the machine itself, the HiSmith - Servok Premium Sex Machine (App) is one of the more capable options in the current range, with app control that gives you finer speed and depth adjustment than a dial alone. The accessory system is the same regardless of which HiSmith machine you own - KlicLok is consistent across the range.
Worth noting for buyers considering their total outlay: the machine is the main investment, and the attachments are relatively incremental from there. Most users start with one or two attachments and add over time. You do not need to buy the full range on day one to get a lot of use out of the machine.
Lubricant, Cleaning, and Setup Notes
Silicone attachments require water-based lubricant. Silicone-based lube degrades silicone toys over time, which is not something you want happening to attachments that attach to a machine running at speed. Water-based is the straightforward answer and causes no issues.
Cleaning is standard - warm water and a toy-safe antibacterial cleaner. KlicLok attachments come off the machine in seconds, which makes cleaning more practical than it would be with a fixed attachment system. That convenience adds up if you are using the machine regularly.
Building Out Your HiSmith Setup Over Time
The honest approach to accessory buying is to start with what matches your actual use case rather than buying broadly. If you primarily use the machine for vaginal stimulation, one or two well-chosen dildos will serve you better than a large collection with mixed relevance. If stroker use is the main goal, the stroker attachments are where the money goes.
The HiSmith Machines & Accessories collection has everything listed in one place, which makes it easier to compare what is available without bouncing between categories. The Sex Machines collection is worth a look if you are still deciding on the machine itself or considering additional units.
For accessories that complement your machine without being HiSmith-specific, the broader Sex Machine Accessories range covers items like mounts, positioning gear, and additional adapters.
The KlicLok system is genuinely well designed - it takes a machine that would otherwise be a fixed-function device and turns it into something you can meaningfully customise. Getting familiar with what is available means you can add to your setup with confidence rather than guesswork.

Frequently Asked Questions
What does KlicLok mean on HiSmith accessories?
KlicLok is HiSmith's proprietary quick-release attachment system. It allows compatible dildos, strokers, and adapters to snap onto HiSmith machines quickly without tools. Any accessory labelled KlicLok in its title is designed to connect directly to a HiSmith machine's mounting connector.
Can I use any dildo with a HiSmith machine?
Not without an adapter. HiSmith machines use the KlicLok connector, so attachments need to be either natively KlicLok-compatible or fitted with a suction cup adapter. The HiSmith 4.5 inch Red Suction Cup Adaptor (KlicLok) lets you mount most standard suction-cup dildos onto the machine, which significantly expands your options.
Are HiSmith attachments compatible with all HiSmith machines?
KlicLok attachments are designed to work across HiSmith machines that feature the KlicLok connector. Most current HiSmith machines use this system, but it is worth confirming your specific model supports KlicLok before purchasing accessories separately.
Do HiSmith stroker attachments work the same way as dildo attachments?
Yes - HiSmith stroker attachments that carry the KlicLok designation connect to the machine the same way dildos do. The machine drives the stroker back and forth over the user rather than the other way around, and some models like the Rotating Stroker also add rotational motion on top of the thrusting.
