Overview
The Festool 577101 CT AutoClean Antistatic Hose, 36mm x 11.5 ft is a suction hose made for dust extraction during drywall sanding and similar cleanup applications. This is a vacuum accessory designed for connecting a dust extractor to the Festool PLANEX drywall sander and other tools that accept a 36 mm hose. Model Number 577101. If you spend your day sanding compound and chasing fine dust, this hose matters because it is built to stay light, flexible, and secure instead of turning into dead weight hanging off the tool.
What sets this hose apart is how clearly it is aimed at real drywall work. The 36 mm diameter supports strong airflow for dust collection, while the 11.5 ft length gives you enough reach for wall and ceiling work without feeling overly long or sloppy. Festool also calls out an ultra-lightweight build and extreme flexibility, which is exactly what you want when the hose is moving with a long-reach sander. A stiff hose can pull the tool off the wall, wear you out faster, and make finishing work harder than it needs to be.
The connection details are just as important as the hose itself. Festool includes a flange that locks the hose to the PLANEX for a secure fit, so it is less likely to come loose while sanding. That is a practical feature, not a throwaway spec. Anyone who has had a hose pop loose mid-pass knows it costs time, makes a mess, and breaks your rhythm. On finish sanding, that kind of interruption is a pain you do not need.
This hose is also antistatic, which helps reduce static buildup when moving fine dust through the line. In a dust extraction setup, that matters for day-to-day usability and cleaner handling. Festool also lists the hose as kink-resistant and temperature-resistant up to 158 degrees Fahrenheit, so it is built for jobsite use rather than delicate shop-only handling. The result is a hose that can bend, move, and get dragged around without constantly collapsing or fighting airflow.
Another feature that stands out is the bypass sleeve for extremely light fillers. On some drywall surfaces, too much suction can make a sander feel like it is glued to the wall. The bypass sleeve lets you reduce that suction effect to an absolute minimum, which helps the PLANEX move more freely when you are sanding light material. That is the kind of detail pros appreciate because it directly affects finish quality and user fatigue.
In terms of compatibility, this Festool suction hose is specifically suited for the PLANEX drywall sander and also works with other tools that accept a 36 mm, or 1-1/2 inch, hose connection. Festool does note one exception: it is not for use with the HL 850 planer. So if you are already in the Festool dust extraction system and need a hose that is purpose-built for sanding, this one fits that role cleanly.
Who should buy it? Drywall contractors, remodelers, painters doing prep, and serious DIY users who want better dust control with a long-reach drywall sander. If your priority is keeping the hose light, keeping airflow consistent, and keeping the connection secure on a PLANEX setup, this is the right kind of accessory. It is not a generic hose meant to sort of work. It is built around drywall sanding where hose behavior actually changes how the tool performs.
Made for Drywall Sanding Control
When you are running a drywall sander, hose stiffness matters more than people think. The Festool 577101 CT AutoClean Antistatic Hose is built to stay light and flexible so the hose follows the tool instead of pulling against it.
- Ultra-lightweight design helps reduce drag during extended wall and ceiling sanding
- Extremely flexible, kink-resistant construction supports smoother tool movement
Secure Fit Where It Counts
A hose that disconnects in the middle of sanding is wasted time. Festool adds a flange that locks the hose to the PLANEX, giving you a more secure connection during repetitive overhead and wall work.
- Designed for the Festool PLANEX drywall sander
- Also fits other tools that accept a 36 mm, 1-1/2 inch hose, except the HL 850 planer
Better Dust Flow, Less Fighting the Wall
Fine drywall dust needs reliable airflow, but too much suction can make a sander feel stuck. This hose uses a bypass sleeve so you can cut the suction effect down when working with very light fillers.
- Antistatic hose design helps manage fine dust in extraction setups
- Bypass sleeve reduces wall suction for easier control on light filler sanding
