Key Features
AUTOCLEAN SuctionFine dust loads filters fast. The automatic main filter cleaning system helps the extractor hold suction longer, cuts downtime, and reduces filter maintenance on high-dust work. Smarter Start-UpBuilt-in Bluetooth and the automatic outlet module let the extractor start with compatible cordless or corded tools, so you spend less time walking back to the vacuum and more time working. 36L Jobsite CapacityThis Festool dust extractor is sized for real production work with a 9.5 gallon container, strong airflow, and mobile wheels that make it easier to use in the shop or move around a jobsite.
Overview
The Festool 577874 CLEANTEC CT 36 EI AC AutoClean HEPA Bluetooth Dust Extractor is a professional dust extractor built for high-volume dust collection in the shop and on the jobsite. This is a dust extractor designed for dry and wet extraction, tool-triggered dust collection, and fine-dust cleanup. Model Number: 577874. If your work creates a lot of dust and you need suction that stays consistent instead of falling off as the filter loads up, this is the reason to look at the AC version.
The headline feature here is Festool’s enhanced AUTOCLEAN system. Instead of letting fine dust choke off airflow and force frequent manual maintenance, the extractor automatically cleans the main filter to help maintain suction. Festool also lets you set cleaning intervals of 15, 30, 60, or 120 seconds through the app, which matters when you’re matching the machine to the dust load of the job. On heavy drywall sanding or other fine-dust applications, that translates to longer working intervals and less lost time.
Performance backs that up with up to 138 CFM of airflow and a maximum vacuum of 96 inches static water lift. Those numbers matter because a dust extractor is only useful if it can actually pull dust at the tool and keep pulling as the work goes on. The compact high-performance turbine is built around that goal, and the five suction levels give you a way to dial the machine back when full power is not the right move for the task or the material.
Festool also did the everyday usability work that separates a good extractor from one that becomes a hassle. Touch controls keep operation simple, the anti-static hose setup helps reduce static buildup, and the integrated hose garage plus cord wrap keep the machine organized when you’re moving from cut to cut or loading out. Large pivoting wheels improve mobility, and the integrated brake helps keep it where you park it. That sounds small until you’re working on finished floors or a crowded remodel.
For system users, this extractor fits the broader Festool approach. It has a built-in Bluetooth interface, so it can start automatically with compatible Festool cordless tools or an optional remote control. It also includes an automatic electrical outlet module for corded power tools, which means the extractor can run when the connected tool runs. The T-LOC top makes it easy to attach Systainers, so the extractor can do more than collect dust. It can also function as part of how you move tools and accessories around the site.
Capacity is another big reason to step up to this model. The container holds 9.5 gallons, with a 9.0 gallon filter bag capacity, so it is better suited to longer work cycles than smaller extractors. That matters if you’re doing production sanding, repeated cleanup, or moving between tools without wanting to empty the machine constantly. The listed dimensions of 25 inches long, 14.4 inches wide, and 23.4 inches high keep it compact enough to maneuver while still giving you a useful amount of storage volume.
The included hose is a D 36 x 3.5 smooth anti-static hose, which is great for high airflow applications and snag resistance. It is worth noting that included hose selection matters in the Festool system. Based on the included hose model and customer feedback, buyers using smaller-port tools may want to confirm hose fit or plan for the right adapter before checkout. That is not a knock on the extractor itself. It is just the kind of detail that makes a difference when you’re building out a complete dust extraction setup.
Who should buy it? This is a strong fit for drywall pros, remodelers, finish carpenters, shop users, and anyone already invested in Festool tools who wants a serious HEPA dust extractor with automatic filter cleaning. If your dust load is light and occasional, there are smaller and cheaper ways to go. If you’re regularly dealing with fine dust, tool-triggered extraction, or long sanding sessions, the CT 36 EI AC HEPA makes a lot more sense.

Pro Tip
If you’re collecting heavy fine dust, use the app to shorten the AUTOCLEAN interval so suction stays consistent longer. For lighter cleanup or mixed work, lengthening the interval can reduce noise and interruptions without giving up performance.
Tool Nut’s Take
Tool Nut’s Take
A serious extractor for people who actually make dust all day
The Festool 577874 CLEANTEC CT 36 EI AC AutoClean HEPA Bluetooth Dust Extractor earns its keep when fine dust, long run times, and tool-triggered workflow are part of the job.
- Who it’s for: Pros running sanding, cleanup, and dust-control tasks regularly, especially drywall and interior finish work where clean air and consistent suction matter.
- Why it stands out: AUTOCLEAN, HEPA filtration, Bluetooth start capability, and a useful 36-liter class capacity make it more than just a vacuum.
- Worth knowing: The included 36 mm hose is great for airflow, but hose fit matters. If your setup uses smaller-port tools, double-check compatibility or plan on the right adapter.
