  • Product Overview

    The Nilfisk ALTO Aero 21 INOX Wet/Dry Vacuum was designed for industry-leading suction performance at a competitive price. A compact design makes it easy to maneuver and transport, while a powerful motor makes it an ideal shop vacuum for workshops, jobsites, the automotive industry, and construction sites. A 5-gallon collection container is made of heavy-duty stainless steel and is simple to empty, and it offers a 127 maximum CFM and 84-inch water lift.

    Easy-to-use features, integrated accessories, and a lightweight design make the ALTO Aero 21 INOX a customer favorite.

    Nilfisk's Push & Clean filtration system is a semi-automatic system that quickly cleans and maintains the filter for optimal productivity. For the highest level of filtration, consider the Aero 21 INOX HEPA Wet/Dry Vacuum model, which includes a HEPA filter to remove 99.97% of dust and debris down to .3 microns.

    Top-of-the-Line Reliability

    The Nilfisk ALTO Aero INOX series is built with German engineered technology to ensure the highest-quality clean and reliability. Since Nilfisk engineers used customer understanding and technical expertise to create the ALTO Aero 21 INOX to ensure low maintenance clean-up. Taking wet-dry vacuuming to a new level of productivity, this model makes disposing of wet or dry waste a quick task. Its heavy-duty, stainless steel 5-gallon (20 liter) container can quickly be removed for emptying, and integrated accessories make any tough job manageable.

    Versatile and Maneuverable Design

    Having a lightweight canister design makes the Nilfisk ALTO Aero 21 INOX a great option for cleaning even the tightest of spaces. It also allows for easy transport around your home or to various jobsites. Since you just need a standard 120-volt outlet, you can pretty much take this vacuum anywhere. Combine that with its ability to clean indoor and outdoor spaces (as well as wet and dry applications), and it's easy to see why it's a customer favorite.

    Available HEPA Upgrade

    The Nilfisk ALTO Aero 21 comes standard with a washable, efficient PET filter. This washable filter removes impurities from your air as you make quick work of messy wet or dry applications. If you're looking for a superior filtration with HEPA certification, consider the Aero 21 INOX HEPA model. This filtration catches 99.97% of all particles down to the .3 microns. The available upgrade makes this model compliant with EPA RRP, OSHA, NIOSH, and DoD standards.

    Included Accessories

    Even tough-to-reach spots can be cleaned thanks to a transportable design and the following included attachments:

    • 11.5-foot hose
    • Aluminum extension tube
    • Floor nozzle for wet and dry applications
    • Crevice nozzle
    • Universal nozzle
    • Tool holder kit
    • Dust bag

    Additional Features

This semi-automatic system blasts dirt off the filter to easily restore high suction performance.
    • Indoor/Outdoor Use: This model can be used to clean indoor or outdoor spaces quickly and efficiently.
    • Lightweight Design: Weighing at just 10 pounds, this model is easy to use and transport from site to site.
    • Low-Noise: Despite its powerful suction, it's also designed to be super-quiet and only reaches up to 64 dB while in operation.
    • Standard Voltage: Plug this powerful wet/dry canister vacuum into any standard 120-volt outlet and start cleaning.
    • ETL-Approved: All vacuums in the ALTO Aero INOX series have received the ETL safety and electrical approval.


    Make quick work of any mess with this Nilfisk Aero INOX Wet/Dry Vacuum and its various upgraded features, including a semi-automatic filter-cleaning system that ensures maximum productivity.
