Key Features
Strong Suction, Small FootprintThe Festool 578512 CT MIDI I HEPA Bluetooth Dust Extractor gives you 130 CFM in a compact body that is easy to move around a house, shop, or jobsite. You get real dust control without dragging around a full-size extractor. Automatic Start OptionsBuilt-in Bluetooth and a tool-triggered outlet let the extractor start when your connected tool starts. That saves steps, keeps dust collection consistent, and makes sanding, routing, sawing, and drilling less of a mess. Easy Filter MaintenanceManual filter cleaning and an externally accessible main filter help maintain suction without taking the whole unit apart. That means longer work time before you need to stop and deal with clogs.
Overview
Festool 578512 CT MIDI I HEPA Bluetooth Dust Extractor is a compact mobile dust extractor built for contractors, installers, finish carpenters, and serious DIY users who need clean work with less hassle. This is a dust extractor designed for on-site dust collection, cleanup, and tool-connected extraction during sanding, routing, sawing, and drilling. Model Number: 578512. If you want a unit that is easy to move but still has the suction and control features that matter on real jobs, this is the lane the CT MIDI I is built for.
The big reason this extractor stands out is how much performance Festool fits into a small platform. With up to 130 CFM of airflow and a maximum vacuum rating of 96 in static water lift, it is built to keep up with common power tool dust collection tasks and final cleanup without feeling underpowered. The suction is adjustable in five levels, which matters when you are switching between tasks like sanding a painted door, trimming material indoors, or drilling where too much suction can fight the tool.
Festool also got the day-to-day usability right here. The touch controls are simple and easy to use, even when you are wearing gloves or working in dusty conditions. The smooth tapered suction hose is designed to reduce snagging, which is a small detail until you are dragging a hose around finished flooring, around sawhorses, or along a guide rail all day. The flat top gives you a usable storage surface, and the integrated hose garage and cord wrap keep the setup from turning into a pile of hose and cable in the van.
Filter access is another practical improvement. The main filter can be replaced from the outside, and the manual filter cleaning function helps restore airflow when the filter or bag starts to load up. In plain terms, that means you can keep suction where it needs to be and use more of the bag capacity before stopping. For anyone doing repeated sanding or punch-list work inside occupied spaces, that is a real time-saver.
Dust control is only half the story. The CT MIDI I HEPA is also set up to work smarter with your tools. The built-in electrical outlet supports tool-triggered auto-on operation for corded tools, so the extractor starts with the tool instead of forcing you to make a second trip. Integrated Bluetooth expands that to certain cordless setups when used with Bluetooth battery packs or an optional remote control. That makes this extractor a better fit for mixed corded and cordless workflows than a basic shop vacuum.
On portability, this unit lands in a very useful middle ground. It is lighter and easier to carry than a larger extractor, but it still gives you a 4.0 gallon container capacity and 3.3 gallon filter bag capacity. The chassis is built for jobsite movement, with large rear wheels, front casters, and a locking brake to keep it planted once you have it where you need it. Festool also integrates the extractor with its Systainer system through the T-LOC connection, which matters if your workflow already revolves around stacked tool storage and mobile setups.
The wet extraction capability adds flexibility, but there is an important detail: wet extraction requires a special wet filter. The built-in LevelStop system shuts the motor down when collecting water to help protect the machine. That makes this more versatile than a dust-only extractor, but it is still clearly optimized for clean, mobile dust extraction around power tools first.
Who should buy it? If you work inside finished spaces, do installation work, punch-list work, cabinet fitting, trim, door prep, flooring, or light remodeling, this Festool dust extractor makes a lot of sense. It is especially good for users who care about mobility, cleaner indoor work, and better integration with cordless and corded tools. If you need maximum debris capacity for heavy demolition, you would step up in size. If you want a compact extractor that travels well and does the job right, this one is right in the sweet spot.
