Key Features
HEPA Dust ControlFull-unit HEPA certification helps keep fine dust contained during cleanup and tool-connected collection, which matters when you are working in finished spaces, occupied rooms, or small shops. 5-Stage Suction ControlThe adjustable turbine lets you dial suction to the task, so you can clean heavy debris, handle lighter finish work, or back it down when full pull would be too aggressive. Festool CT 15 MobilityThis compact mobile dust extractor is built to move easily between rooms, vehicles, workshops, and jobsites, with onboard accessory storage and a chassis designed for daily transport.
Overview
The Festool 578441 CLEANTEC CT 15 E HEPA Dust Extractor is a compact wet/dry mobile dust extractor for cleanup work and tool-connected dust collection. This is a dust extractor designed for cleaning jobsites, workshops, garages, vehicles, and occupied spaces while also supporting cleaner work with corded tools. Model Number 578441. If you need a smaller extractor that still delivers serious suction, HEPA-level dust control, and easy transport, this is the one aimed at everyday cleanup without stepping up to a larger unit.
What makes the CT 15 matter is how it balances airflow, usable capacity, and portability. It delivers up to 130 CFM and up to 96 inches of static water lift, which gives it the pull needed for fine dust, general debris, and water pickup. Festool also gives you five suction settings, so you can tune the extractor to the job instead of running full power all the time. That matters when you are moving between shop cleanup, interior finish work, vehicle detailing, and tool-connected dust collection.
The container size is another strong point. Festool rates it at 3.96 gallons, and the internal layout is built to make better use of that volume so you can work longer before stopping for a bag change. On smaller jobs and punch-list work, less downtime is a real benefit. You spend more time cleaning or cutting and less time opening the extractor. For contractors working in finished or occupied spaces, that kind of efficiency adds up fast.
From a design standpoint, the CT 15 is clearly built for movement. It weighs 23.1 pounds, uses a compact footprint, and rides on a stable chassis with steel axles. The oversized rear wheels and front casters make it easier to roll around a shop or pull across a jobsite, while the flat top gives you a place to set tools or materials when space is tight. Festool also includes onboard storage for the cleaning accessories, so the hose and nozzles are where you need them instead of loose in the van.
Festool kept operation simple. The touch controls are easy to use, even when you are working quickly or wearing gloves, and the main filter can be replaced from the outside. The antistatic hose helps reduce static buildup while you work, which is a small detail that makes the whole setup more pleasant to use over a long day. Wet and dry capability gives the machine more range than a dust-only extractor, especially for service work, remodel cleanup, and garage use.
The Festool 578441 CLEANTEC CT 15 E HEPA Dust Extractor also includes a tool-activated outlet for corded tools, so the extractor can start automatically when the connected tool starts. That is a practical feature if you are trying to keep dust under control without adding extra steps every time you make a cut or sand a surface. It is worth noting that this version does not have Bluetooth capability, so this is the right choice for buyers who want a straightforward corded setup without paying for wireless extras they will not use.
Who should buy it? This extractor makes the most sense for remodelers, finish carpenters, installers, shop users, vehicle detailers, and serious DIY users who need one machine for dry debris, wet pickup, and general dust management. It is especially strong for smaller crews and service work where compact size matters as much as suction. If your work takes you into finished homes, offices, or customer-facing spaces, the HEPA filtration and easy mobility are the real selling points.
Easy to Move From Room to Room
The CT 15 is built for the kind of work where the mess moves and the extractor has to move with it. Its compact body and mobile chassis make it easy to take from the van to the jobsite, then from one room to the next.
- Compact design with a 23.1 lb tool weight
- Stable chassis with steel axles for durability
- Flat storage area on top keeps materials close by
Controls That Stay Simple on the Job
Festool did not overcomplicate the interface here. The touch control layout is quick to understand, and the five-level suction adjustment lets you match pickup strength to the mess instead of using one setting for everything.
- Five-stage suction control for better task matching
- Externally accessible main filter simplifies maintenance
- Antistatic hose helps reduce static while you work
Carry It When Rolling Is Not an Option
Service work does not always give you smooth floors and open hallways. The CT 15 stays manageable when you need to carry it up stairs or into tight interior spaces, which is exactly where a smaller extractor earns its keep.
- Compact dimensions: 18-1/2 in x 12-19/32 in x 17-1/8 in
- Designed for occupied spaces, garages, cars, and workshops
- Wet/dry capability adds flexibility beyond dust-only cleanup

Pro Tip
Use the lower suction settings when cleaning upholstery, trim work, or other light materials so the hose does not grab the surface. Then bump it back up for concrete dust, jobsite debris, or wet pickup. That is where the CT 15’s five-step control really pays off.
