Hilti Dust Extractor VC 4X-22 | Tool Review

The Hilti Dust Extractor VC 4X-22 is a recent upgrade to their 22-Volt dust extractor line up. Its touted to have more efficient suction and to accommodate user requests and demands for a larger capacity tank-on-wheels for diamond concrete cutters. Here’s what stands out about this upgrade:
Dust Extractor VC 4X-22 | Multiple Configurations
The dust extractor offers several configurations:
• Vacuum head unit
• 8-liter tank that connects to a backpack set
• 15-liter tank that connects to a wheeled dolly
• Plastic bags for silica dust with a zip tie
• Fleece bags specific to sawdust and other debris
• 6-foot hose designed for the backpack and wall drilling
• 9-foot hose for both configurations
• Bluetooth dongle
• HEPA filter
• Universal wet/dry filter
Interesting Note: The plastic bags have holes that should be inside the tank to prevent suction into the filter, allowing better performance with some dust leakage.
Hilti VC 4X-22 | Runtime and Bluetooth Dongle
The Hilti Dust Extractor VC 4X-22 when equipped with a 255 battery, the vacuum runs for 21 to 22 minutes continuously. However, the vacuum is primarily designed as a dust extractor, connected to a tool that powers on and off with the tool. In this mode, the battery can last an entire day or more.
Hilti provides a Bluetooth dongle that can attach on the hose end or directly on the tool.
We recently used the vacuum and dongle on our miter saw while cutting PVC trim. The vacuum ran all day, in an on / off fashion, and battery was half full at the end of the day. To make sure we used the vacuum, we attached the dongle “font and center,” on the miter saw handle. This reminded us to turn it on and off as we made our cuts. The dongle was designed to preserve battery life, and it worked for us.
Interesting Note on Hilti Battery Charging:
The HILTI charger can charge the battery in less than an hour, reaching 80% in the first half hour. So, if you need a battery sooner, you can pull it off the charger after half an hour and be at 80%. Regardless, having two batteries will guarantee you all-day runtime.
Powerhead Design
The powerhead has a top, folding handle that makes carrying this vacuum easy. There are two large, solidly designed clamps to attach the power head to the vacuum tank. The filter attaches underneath the powerhead and is easily removed. The black flange between the filter and powerhead is designed to install only one way on the power head. HILTI updated this because many users were installing it backward, introducing air into the turbine and blowing out the sides.
User Interface Dashboard
The dashboard on the Hilti Dust Extractor VC 4X-22 is intuitive, and has symbol-like labels to assist users, although I still feel that HILTI could improve their manuals. The dashboard has an on/off, and Bluetooth knob.

There is also an LED indicator to alert users when the tank is full of water. Yes, this vacuum can be used as a wet/dry vac, why I’m not 100% sure, I’d rather use a cheap shop vac for that. Maybe Hilti has a connection for concrete wet cutting. There is also an ECO button on the dashboard which allows users to reduce vacuum power to 60% to conserve battery or when 100% suction is not needed, such as in some sanding applications.
Under the head unit, two stainless steel sensors detect water levels.
Suction and Power
The HILTI VC 4X-22 certainly has plenty of suction for both tool attachment and cleanup. While not designed for heavy debris and demolition waste, it works well for small cleanups. HILTI sells accessories like floor sweeps and nozzles, making this vacuum suitable for both dust extraction and small service call cleanups.
I’ve also used it to collect sawdust and on a few small clean ups.

15-Liter Tank | 2-Wheel Cart
The Hilti Dust Extractor VC 4X-22 tank is engineered with reinforced ribbing to reduce collapsing from the increased vacuum power pressure. The larger tank improves performance by maintaining vacuum pressure inside the tank as it fills with debris. The telescoping cart handle works great at maneuvering the vacuum, users can lock the handle height, by activating a rotating pivot lock. Black supports or stair slides mounted on the cart, near the wheels protect stairs during navigation.

The tank cart is backwards compatible with HILTI’s VC 140, allowing for an upgrade or exchange through the fleet program
Backpack Harness | 8-Liter Tank Setup
The backpack setup is designed to be used with the smaller, 8-liter tank configuration. It’s designed for users who are wall and overhead drilling. The backpack harness has 4-tabs that intersect into the powerhead and a red clip that locks it in pace. We found the backpack attachment easy to attach to the powerhead and smaller tank. Its comfortable and easy to use.

Price
• Vacuum with 8 liter tank: $549.00
