Best Commercial Canister Vacuum Cleaner: NSS® Model M-1 “Pig”® Vacuum

Vacuums are an important component of any facility maintenance program. Used in all three phases of floor care, your cleaning staff spends a lot of time using vacuums. 

One study found that the average commercial cleaning worker uses a vacuum for 1-3 hours a day. 

As one of the most used pieces of equipment, it is critical to select the right one for your facility. The right commercial vacuum will allow your staff to enjoy increased productivity and better results. 

There are several different types of vacuum cleaners and each is available to tackle different problems like spot cleaning or wet residue pick-up. Determining the best vacuum will depend on the area, soil, and the level of traffic you are dealing with.

To help you select the best commercial vacuum for your facility we compiled a list, which included the NSS® Model M-1 “Pig”®.

What makes the NSS® Model M-1 “Pig”® one of the best vacuums of 2021?

The NSS® M-1 “Pig”® canister vacuum offers a faster, easier, and safer way to dust surfaces up to 25 feet in the air without using a ladder or a lift. Additionally, this vacuum is extremely versatile and effectively removes dust and dirt from drapes, hanging signs, and other above-the-floor fixtures without sticking to surfaces. 

Below we’ll review what makes the NSS® Model M-1 “Pig”® one of the best commercial vacuums of 2021. 

NSS® Model M-1 “Pig”® Canister Vacuum 

Automatic Variable Suction 

NSS Model M-1 PIG Canister VacuumThe Model M-1 pig is equipped with a special suction system that prevents it from sticking to surfaces. 

Expertly designed, the Model M-1 pig has the ability to move a lot of air capturing dust particles while easily moving along surfaces like curtains, walls, and ceilings. 

This innovative release system makes the M-1 the perfect vacuum for cleaning overhead and above the floor surfaces such as tall walls, pipes, ledges, skylights, curtains, banners and more. 

Overhead Cleaning Kit

Safely cleaning above-the-floor surfaces is often time-consuming, difficult, and a safety hazard.  

The NSS® Pig® vacuum cleaner can be equipped with an overhead cleaning kit. For maximum versatility, the kit comes complete with three stackable wands, three wand extenders, two pipe cleaning tools, and three dusting brushes. 

The wall and pipe tool kit can be arranged to clean up to 25 ft. overhead without the use of ladders and risk of falls.  

Eliminating the need for a ladder or lift from your staff's cleaning routine helps lower the risk of injury from falls while vacuuming. 

Large Capacity 

Proving long cleaning times, the NSS® Pig® vacuum cleaner has an extra large 12-gal filter bag. 

The large bag holds up to 5x more than the standard upright. The larger the collection bag, the greater amount of area staff can clean before having to stop and empty the bag. 

When the bag does become full, there is a zipper opening on the top of the outer reusable cloth bag that allows staff to quickly change the disposable paper bag inside.  

Fully-Directional Front Wheels 

M1 Pig InsideThe Model M-1 Pig has fully directional front wheels that eliminate drag. The wheels allow the user to easily maneuver the vacuum in any direction and on a variety of surfaces. 

Improved Indoor Air Quality 

Filtering 99.4% of dirt and dust 0.3 microns or bigger reduces the amount of particles in the air, creating a cleaner and healthier environment.

Indoor air quality is especially important in facilities looking to achieve LEED certification. 


Weighing just 35 pounds, the pig vacuum is light and easily maneuverable for the operator.

Lighter machines reduce the stress put on the operator, allowing them to complete more cleaning tasks during a shift. 

Scrap Trap 

On the front of the machine, the M-1 has a “scrap trap” that collects and stores debris. The trap allows the vacuum to suck up coins, paper clips, nuts, bolts and more. 

The objects are caught in the front chamber before they can reach the fan, protecting the machine from damage and saving you in costly repairs. 

Blower Feature 

Adding to this machine's versatility, the Model M-1 Pig® vacuum cleaner can be used as a powerful blower. All the user has to do is move the hose from its normal location to the filtration bag opening. 

Carpet and Hard Floor Kits 

Available as additional accessories, NSS® has a variety of carpet and hard floor tool kits that can increase the efficiency of the procedures. 

For example, the kits can supply staff with crevice tools or round brushes to help reach into areas that staff would normally struggle to clean. 

Tools and accessories manufactured by NSS® come with their own 10-year warranty. 


WarrantyBacked by a 7-year limited warranty, the M-1 is made from durable materials that are built to last. 

Compared to other vacuums on our list, this is the longest available warranty. The warranty can help save you money in repair costs over the life of the machine.

As is typical with most commercial vacuums, the warranty does not include wear and tear items such as brushes, accessories, and filters. However, as mentioned above some tools and accessories come with their own warranty of ten years. 

Final Thoughts 

The NSS M-1 “Pig” is ideally suited for locations where users need to vacuum hard and carpeted floors as well as overhead areas such as in schools and universities, office buildings, and retail stores.

Unlike other canister vacuums, the Model M-1 is extremely versatile. Conventional vacuums are restrictive and require lifts and ladders to reach overhead areas. 

Lifts and ladders are often dangerous and a safety hazard. 

This canister vacuum can be paired with an overhead cleaning kit that creates a safer work environment and boosts cleaning efficiencies.
