  • Product Overview

    The new Nilfisk ALTO AERO series combines industry-leading suction and performance with competitive pricing. The Nilfisk ALTO AERO 21 5-Gallon Wet/Dry Vacuum features a compact design that makes it ideal for both open areas and hard-to-reach spots in residential spaces, workshops, and industrial job sites.  A 20-liter container capacity is supplemented with a 127 maximum CFM and 84-inch maximum waterlift. Easy-to-use features, integrated accessories, and a lightweight design make the ALTO AERO 21 a customer favorite.

    Nilfisk's Push & Clean filtration system includes a semi-automatic filter cleaning system for quick and easy maintenance. For the highest level of filtration, consider the Aero 21 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 series is built with German engineered technology to ensure the highest-quality clean and reliability. Wet/dry clean-up is made low maintenance thanks to Nilfisk engineers using customer understanding and technical expertise when creating the AERO 21. Taking wet-dry vacuuming to a new level of productivity, the Nilfisk AERO 21 makes disposing of wet or dry waste a quick task. The lightweight, plastic 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 5-Gallon Shop Vacuum 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 customers use it for various jobs.

    Available HEPA Upgrade

    The Nilfisk ALTO AERO 21 comes standard with a washable, efficient PET fleece filter. This washable filter removes impurities down to 1 micron 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 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.

    Even tough-to-reach spots can be cleaned thanks to a compact, transportable design and the following included attachments that come with the Nilfisk ALTO 21 5-Gallon Wet/Dry Vacuum :

    Additional Features

    • Push & Clean Filtration System: Working with fine dust can mean clogged filter cartridges.

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 series have received the ETL safety and electrical approval.


    A powerful vacuum capable of wet and dry applications indoors or outdoors, the Nilfisk Aero 21 will clean even your hardest-to-reach spaces.

    • Powerful Suction: This model's motor has a 127 maximum CFM and an 84-inch waterlift.
    • Compact Design: Few wet/dry vacuums offer the maneuverability and transportability that the Nilfisk ALTO Aero 21 offers.
    • Competitive Pricing: Nilfisk engineers' goal was to make an affordable machine, and its competitive price makes it accessible for people at nearly any job site.

    Things to Consider
