Best Pre Roll Machines of 2025
If your dispensary or pre-rolled cone operation is still filling cones by hand, you’re missing out on the automation and efficiency that’s possible. These days, large-scale operations that aren’t using the best pre roll machines are behind the curve. You can fill as many as 450+ cones every 3 minutes!
As more and more cone filling machines come to market, claiming they have the best technology, it can overwhelm buyers. In fact, many of the machines out there are not as efficient as they claim to be. They’re also made from low-quality materials that break or degrade quickly, causing more headaches than they’re worth.
Don’t worry, we’re here to help. We decided to put together a list of the best pre roll machines currently on the market, to eliminate any uncertainty. From top brands like Futurola or STM Canna, to lesser-known contenders like the Doob Cube or Sluice Box – we’ve got something for everyone!
What is the best pre roll machine of 2025?
Here are our favorite pre roll machines in the industry, in no specific order. When you think of machines like these, you might assume they are too expensive for most operations.
However, as you’ll discover below, there really is a pre roll machine for every size facility!
The Futurola Knockbox Family
Futurola is the first to bring this sort of machine to the market, and have earned the right to call themselves “pioneers”.
Their flagship product, the Knockbox, has been revamped a number of times, and the current model is the third generation. There are three versions of the Knockbox currently:
They have expanded their line to offer a cone filling machine for facilities of all sizes.
This futuristic-looking machine can bust out 100 pre rolled cones in just 2 minutes, and is compatible with Futurola brand cones. Their cones range in sizes from 0.5 grams to 2.0 grams, but the machine fits all these sizes.
The Futurola Knockbox 3 is known for producing consistent pre rolls every time, packed to perfection. This results in a smooth smoke with an even burn.
There are a number of add ons that will make this machine even better, and take your cone filling operation to the next level.
The Futurola Shredder quickly converts massive quantities of flower into the perfect feedstock for filling your cones. You can also add:
When you grab your Futurola Knockbox, make sure you grab some cones too!
STM Canna Rocketbox 2.0
STM Canna has produced the highest output pre roll machine in the industry – the Rocketbox 2.0.
This is the second version of the RocketBox, which brings a ton of improvements to what was already one of the best pre roll machines.
The price tag reflects what this machine is capable of.
No machine currently provides this level of automation, and the engineering that went into creating this pre roll machine is a marvel.
From a performance standpoint, this machine can work for a number of applications, with the optional add on packages.
The base Rocketbox package can produce up to 3,000 pre roll cones a day, or 453 every 3 minutes!
Another thing that stands out about the RocketBox is the built in training mode.
With every RocketBox purchase, STM Canna will send out a rep to your facility for an entire day of training.
They teach you everything you need to know about the machine, including how to use, clean, and get the most out of it.
Here are some additional improvements the new RocketBox 2.0 brings to the table:
- 3 settings across 1 stage to adjust, fill, and pack.
- More weight parameters which means a lower margin for error.
- Proprietary software to measure density & achieve weight accuracy.
- A larger touch screen control panel.
If you have larger than normal cone filling requirements, the rocketbox is probably your best option. You can also add individual components to supercharge your output, such as:
To take your operation to the next level with this machine, you should also check out the STM Canna Revolution Shredder.
This newly-released shredder allows you to quickly, efficiently, and consistently prepare your flower for perfect pre rolled cones.
STM Canna RocketBox Mini PLUS
Yes, the STM Canna RocketBox is the largest, most sought-after pre roll machine on the market. But it might be a bit much for what some operations need.
That’s why they made the RocketBox Mini PLUS – the most efficient cone filling machine for small to medium operations. This second-generation model greatly improves upon its initial release, offering improvements to the bottom tray to accommodate natural variance in paper cones. And, STM Canna added a new lift plate and new adjustable top tray, too!
This smaller version of the original RocketBox is capable of producing 143 joints in under a minute, and up to 11,000 per day.
This is the go-to pre-roll machine for small craft cultivars and startups, but even larger brands are adding these to their facilities!
You can fill up to 1.2-gram cones, but you can use cones as small as .25 grams. Simply choose the bottom tray you want to use.
With a 90% average fill rate and less than a 10% weight variance, you can accurately fill your cones with as much consistency as possible, without having to run multiple cycles to fill your cones all the way.
Just like when you purchase the original RocketBox, you get access to the exclusive RocketBox technology, along with the STM client portal which sets you up for success, giving you all the information and resources you need to get the highest and fastest ROI on this machine.
The Doob Cube Pre Roll Machines
The Doob Cube is a really simplistic pre roll machine with a budget friendly price tag.
With the flip of a switch, the machine quickly fills 620 Raw 98 Special or RAW Classic 1.25” cones.
This pre roll machine uses a vibrating motor and sifter to ensure a consistent fill every time, without the mess, waste, or manual work!
Another benefit of this pre roll machine is how easy it is to move around your facility and transport from place to place, weighing at just 30 pounds. It has a tiny footprint, but a huge output.
You can customize your machine by adding an additional drop box and cone plate.
This will allow you to load and unload cones while the machine runs, so you can increase efficiency even further!
If you want a low-cost, easy-to-use pre roll machine and you don’t have the demands to warrant a Rocketbox, or even a knockbox, check out the doob cube.
