VacuGlide Modes and Speeds: Every Slot Explained

Most devices give you a dial that cycles through numbered speeds. The VacuGlide 2 works differently. It has a slot system.

A slot is a saved combination of two things: a stroking experience (the rhythm and pattern of the physical motion) and a suction level (how strongly the device holds and stimulates through vacuum pressure). Together they define a complete mode. Switching slots is not just changing how fast the machine moves, it is switching to a different feel entirely.

The VacuGlide 2 ships with a number of pre-loaded built-in slots covering a range of patterns and intensities. These are ready to use from the moment you switch the device on. Beyond those, several slots come empty and are reserved for custom combinations that you set up yourself.

Why slot-based rather than a simple speed dial? Because the two dimensions, stroke and suction, do not always need to move together. You might want a very fast stroke with minimal suction, or a slow rhythmic pattern with maximum hold. A slot lets you define and lock in that pairing and revisit it exactly, without hunting for the right combination each time.

For a deep dive into how suction works on the VacuGlide, see the suction guide.

People often use 'mode' and 'speed' interchangeably when talking about devices like this, and on simpler machines that is fine. On the VacuGlide 2 they mean different things, and knowing the distinction helps you get more out of the slot system.

Speed refers to the rate of the physical stroke: how many times per minute the mechanism completes its full cycle. The VacuGlide 2 has multiple speed levels you can assign within a slot.

Mode (or stroking experience) is the pattern of the motion, not just its rate. Some patterns are constant, some pulse, some build gradually, some alternate between fast and slow bursts. The rhythm is what changes, not only how quickly the mechanism moves.

A slot, then, is always both: a specific speed level combined with a specific stroke pattern. When you save a custom slot you are locking in both of those choices. When you switch slots mid-session, you change both at once.

If you are comparing this to the Autoblow AI Ultra, the slot system is VacuGlide-specific. The AI Ultra uses a different architecture for its mode selection. See the comparison page if you are still deciding between the two.

Switch the VacuGlide 2 on and it boots into a specific startup slot: a moderate stroking speed with a medium suction level. The reasoning is that starting at full power is uncomfortable for most people, so the device deliberately lands somewhere in the middle as a safe starting point.

You are not stuck there. From the startup slot you can:

• Scroll through the built-in slots using the on-device controls
• Jump directly to a saved custom slot
• Adjust the speed and suction individually before settling on a combination you like

The startup slot itself is not user-configurable on the current firmware. If you consistently prefer to start at a different setting, the fastest workaround is to name one of your custom slots something memorable and navigate to it immediately after startup. A few taps and you are at your preferred setting.

The built-in slots on the VacuGlide 2 cover the main territory most people want to explore without needing to configure anything themselves. They are designed to give you a progression from gentle to intense and from constant-rate to patterned rhythms.

A rough breakdown of what to expect:

1. 1Steady low - Consistent pace, minimal suction. Good starting point.
2. 2Steady medium - The default startup. Most people spend some time here.
3. 3Steady high - Full constant-rate at higher speed and suction.
4. 4Pulse slow - Alternating active and brief pause cycles, slow cadence.
5. 5Pulse fast - Same alternating pattern, noticeably quicker.
6. 6Build - Incrementally increases speed and suction over a defined cycle, then resets.
7. 7Wave - Gradual swell and fade rather than a hard pulse.
8. 8Surge - Short high-intensity bursts with slower recovery strokes in between.

These are pre-set and cannot be deleted, though you can move past them to your custom slots whenever you want.

This is where the slot system earns its place. The built-in slots are a solid starting point but they are fixed. Custom slots let you lock in exactly the combination you like.

Via the device controls (no app required):

1. 1Navigate past the built-in slots to an empty custom slot.
2. 2Adjust the speed to the level you want using the on-device buttons.
3. 3Adjust the suction level separately.
4. 4Hold the save button (check the quick-start guide for the exact button; it varies slightly between firmware versions) until the screen confirms the slot is saved.
5. 5The slot now lives at that position and persists across power cycles.

Via the web app (if the device is online):

1. 1Open the VacuGlide 2 in the Autoblow web app.
2. 2Navigate to the mode editor.
3. 3Select an empty slot and adjust the speed and stroking pattern using the interface.
4. 4Save. The change is pushed to the device immediately.

You can overwrite any existing custom slot at any time. Built-in slots cannot be overwritten.

How many custom slots are there? The VacuGlide 2 gives you several empty slots beyond the built-in ones. The exact number may vary with firmware updates, but at launch there are at least four custom slot positions available.

No universal answer, but a few patterns are worth knowing:

• If you are starting a session: The default startup slot or Steady Low is a sensible place to begin. Suction takes a moment to feel natural, and the lower settings give you time to settle in.

• If you want sustained intensity without peaks: A steady high or custom steady slot is more reliable than a pulse pattern. You know exactly what you are getting.

• If you are looking for build and release: The Build slot or a custom slot with a wave pattern works well. The rhythm creates more of an arc to the session.

• If you want to experiment: Move through the built-in slots in order on your first few sessions. Get a feel for how much the stroke and suction variations actually change the experience before committing to custom settings.

The VacuGlide 2 also works with video sync and the AI companion features when connected online, which can override the slot selection entirely and drive the machine dynamically. If you are using the machine offline or in a simpler session, the slots are your primary tool.

Questions about which device is a better fit for you overall? The VacuGlide 2 vs AI Ultra comparison breaks it down in detail.

Do custom slots survive a firmware update?
Usually yes, but it is worth rechecking after a major firmware version bump. Settings are generally preserved, but some large updates can reset user customisations. Make a note of your preferred combinations before updating.

Can I have the same speed at two different suction levels?
Yes, that is exactly what two custom slots are for. Set Slot A to speed 4, suction 2. Set Slot B to speed 4, suction 5. You now have two distinct-feeling slots at the same stroke rate.

What is the difference between suction level and speed?
Speed is how fast the mechanism strokes. Suction is how strongly the vacuum cap creates hold and stimulation pressure. Turning up suction on a slow stroke creates a completely different sensation to the same suction on a fast stroke. The suction guide goes deeper on this.

Can I control the slots remotely?
If the device is online, yes. A partner with your device token can switch between slots through the web app, the same way they can adjust speed. If the device is offline, only the on-device controls work.
