The Festool 577876 Dust Extractor CLEANTEC CT 48 EI AC HEPA is a corded HEPA dust extractor built for professional dust collection in woodworking, remodeling, and jobsite cleanup. This is a dust extractor designed for tool-triggered dust collection and dry or wet extraction. Model Number 577876. If you need strong suction, long run time between service stops, and system-friendly dust control that works with both corded and compatible cordless Festool tools, this is the machine this model is aimed at.

The headline feature here is Festool's enhanced AUTOCLEAN filter cleaning. On fine dust work, suction usually fades as the filter loads up. This system is built to keep airflow more consistent, which matters when you're sanding, grinding, cutting, or doing other high-dust work that would choke a standard extractor faster. Festool lists cleaning intervals adjustable through the app at 15, 30, 60, or 120 seconds, giving you a way to tune the machine for how aggressively the filter needs to be cleaned.

Performance is real-world usable, not just brochure talk. The compact high-performance turbine is rated for up to 137 CFM max volume flow and up to 96 inches of static water lift. That combination is what gives the extractor the pull needed to keep dust moving through the hose instead of settling in the line. The five selectable suction levels also matter more than they sound like they should. Full pull is great for heavy debris and fine dust, while backing suction down helps when you're working with tools or materials that can stick to the surface from too much vacuum.

The platform side is a big part of why pros buy this class of extractor. The automatic electrical outlet module lets the extractor start when a corded power tool is switched on, so the vac works like part of the tool instead of a separate machine you have to babysit. Built-in Bluetooth adds the same convenience for compatible Festool cordless tools or an optional remote control. Festool also ties the unit into its app, which lets you manage functions like filter cleaning intervals instead of relying only on the controls at the machine.

Physically, this extractor is built around mobility and organization. The container capacity is 12.7 gallons, with a 12.2 gallon filter bag capacity, so it is suited to longer work stretches before emptying. Large pivoting wheels help it track around the shop or jobsite, and the integrated brake helps keep it planted once you're in position. Festool also includes the practical stuff that saves aggravation every day: a hose holder, cord wrap, integrated hose garage, and T-LOC top interface for attaching Systainers.

The included smooth, anti-static suction hose is worth mentioning because hose drag is one of those little annoyances that adds up over a full day. Festool uses a conical hose design intended to maintain strong suction while helping the hose move more freely and resist snagging. The anti-static setup helps reduce static buildup during operation, which is especially helpful when you're moving fine dust through the system for extended periods.

For shop and site use, this unit covers more than one role. Festool specifically rates it for dry and wet extraction, so it is not limited to one narrow workflow. In a woodworking shop, it makes sense paired with sanders, track saws, routers, and cleanup tasks. On a remodeling site, it is a good fit when cleaner work matters and you need a larger-capacity extractor that can keep up with multiple tasks throughout the day.

Who should buy it? The best fit is the pro user who already values dust control as part of productivity, not as an afterthought. Cabinet shops, trim carpenters, remodelers, flooring installers, and anyone running Festool's system-based setup will get the most out of it. It is also a smart choice for serious users dealing with lots of fine dust who want a HEPA dust extractor with automatic filter cleaning, tool-triggered operation, Bluetooth connectivity, and enough container volume to avoid constant stops.
