DeWalt Window Vacuum Review
The DeWalt Window Vacuum is a cordless, handheld tool designed to leave glass, tiles, and mirrors streak-free. This review covers its suction power, battery life, and real-world usability based on aggregated owner feedback and published specs.
Quick answer
The DeWalt Window Vacuum is a solid choice for DIYers who already own DeWalt 12V batteries, offering strong suction and a wide blade. However, for pure window-cleaning performance, the Karcher WV 6 Plus remains the top pick for its lighter weight and faster drying time.

Who is the DeWalt Window Vacuum for?
This tool is best for users already invested in the DeWalt 12V ecosystem. If you own a DeWalt 12V drill, screwdriver, or multi-tool, the DCE100 shares the same batteries, saving you money and reducing clutter. It is also suitable for DIYers who clean windows, mirrors, and shower screens regularly and prefer the build quality of a power tool brand over a dedicated cleaning appliance.
Performance and Suction Power
Published specs indicate the DCE100 produces strong suction for a handheld unit. Owner reviews on Amazon and home improvement forums consistently note that it leaves glass streak-free after a single pass, provided the blade is clean. The 10.5-inch blade is wider than many competitors, such as the Karcher WV 2 (9.8 inches), allowing you to cover more area per stroke.
The motor runs quietly compared to a standard vacuum. However, the 100 ml water tank is small. You will need to empty it after cleaning two to three standard-sized windows. This is a common trade-off for handheld window vacs, but it is worth noting if you plan to clean multiple large panes in one session.
Build Quality and Battery System
DeWalt is known for durable tools, and the DCE100 feels solid. The rubberized grip and balanced design make it comfortable to hold. The 2.0 Ah battery provides around 30 minutes of continuous runtime, which is ample for most home cleaning tasks. The battery charges fully in about 45 minutes with the included charger.
The main advantage here is the shared battery platform. If you already have DeWalt 12V tools, you can use their batteries in this vacuum. This reduces long-term cost and waste. If you are new to the system, the starter kit includes one battery and a charger, which adds to the initial investment compared to a dedicated window vac that has a built-in battery.
Alternatives to Consider
For pure window cleaning performance, the Karcher WV 6 Plus is lighter (1.2 lbs) and has a larger 150 ml tank. It also dries faster due to its optimized blade design. The Karcher is often the top-rated dedicated window vac among owners. Another option is the Bosch GlassVac, which is similarly priced and also uses a 12V battery system, but it has a narrower blade and shorter runtime.
If you prefer a corded option for unlimited runtime, the Vileda Window Vac is a budget-friendly choice, though it lacks the suction power of the DeWalt or Karcher. For users who want the absolute best battery compatibility, the DeWalt DCE100 is the clear winner within its ecosystem.
What to Check Before Buying
Before purchasing the DeWalt Window Vacuum, check that you have compatible 12V batteries. The DCE100 is not compatible with DeWalt 20V MAX batteries. Also, consider the weight: at 1.8 lbs, it is heavier than most dedicated window vacs, which can cause fatigue during extended use. Finally, ensure the 100 ml tank size is adequate for your typical cleaning session.
Mistakes to Avoid
A common mistake is not cleaning the rubber blade regularly. A dirty blade will leave streaks. Wipe it with a damp cloth after each use. Another mistake is using the vacuum on soaking wet surfaces without a squeegee first. The tool is designed to remove the last layer of water, not to dry a flooded floor. Finally, do not store the vacuum with water in the tank, as this can lead to mold or damage.
FAQs
Can the DeWalt Window Vacuum be used on wet floors?
