Overview of the Tennant S6 and S7

Tennant's S-series sweepers are some of the most sought-after for commercial environments that need consistent daily debris removal. Think warehouses, distribution centers, schools, or retail floors. 

The S6 and S7 fall under the same design family but they serve totally different facility sizes and budgets. Understanding the Tennant S6 vs S7 split helps narrow the choice before comparing either one to the Terra 28B.

Tennant S6 Features and Specs

• Sweep path: 26”
• Hopper: 9.3 gallons (1.25 cu ft)
• Battery runtime: Up to 2 hours
• Productivity: Up to 18,750 sq ft/hr
• Noise: 61 dBA
• Drive: Manual (brush-assisted)
• Filtration: Self-cleaning filter shaker, 99.5% at 2 microns
• Price: $3,628

The entry point in this Tennant vs Advance sweeper lineup. Manual drive means you actually push the machine. The brushes assist but don't propel the machine forward. That’s fine in tighter spaces and shorter shifts, but it can take a toll over an 8-hour day in a 30,000-square-foot warehouse. 

Filtration is the standout feature: 99.5% efficiency at 2 microns is exceptional for keeping fine dust out of the air in enclosed environments. The most affordable in this conversation at just $3,628, but you get what you pay for. Consider hopper capacity, drive system, and warranty length.

Tennant S7 Features and Specs

• Sweep path: 28”
• Hopper: 12 gallons (1.6 cu ft)
• Battery: 140AH maintenance-free, up to 3 hours runtime
• Productivity: Up to 28,000 sq ft/hr
• Drive: Self-propelled
• Construction: Steel frame
• Price: $7,251

The S7 is the premium Tennant option with self-propulsion, a wider sweep path, a bigger hopper, and an extra hour of runtime. It outpaces both the S6 and the Terra 28B in raw coverage speed at 28,000 sq ft/hr. The 140AH battery offers 3 hours of continuous operation without a mid-shift charge. 

Steel frame construction means this is a machine built to last. The Tennant S7 vs Advance Terra 28B matchup is the tighter head-to-head because both machines are self-propelled with 28-inch sweep paths. They compete more directly on capacity, price, and after-sales support.

Overview of the Advance Terra 28B

• Sweep path: 28”
• Hopper: 15 gallons
• Battery: 86AH gel (maintenance-free)
• Productivity: Up to 20,000 sq ft/hr
• Noise: 59 dBA
• Drive: Self-propelled
• Filtration: Durable polyester panel filter
• Technology: A.S.A.P. (All Surface All Purpose)
• Price: $5,967

The Terra 28B is Nilfisk Advance's direct competitor to Tennant's S7, yet it’s $1,284 less with a much bigger 15-gallon hopper and a stronger 3-year warranty on parts and labor. That tells you a lot of what you need to know in comparing Tennant vs Advance floor sweepers. 

Advance's A.S.A.P. sweeping technology automatically adjusts to different floor surfaces. That’s great for facilities that transition between hard floors, carpet, and entrance mats throughout a single sweep pass. 

One-Touch operation streamlines startup, while the tool-free broom and hopper do the same for daily maintenance. It’s super simple. And, it’s the quietest commercial floor sweeper machine in this comparison at just 59 dBA. That matters for buildings worried about disrupting work with daytime sweeping.

Tennant S6 and S7 vs Advance Terra 28B: Side-by-Side Comparison

There’s plenty of overlap between these machines, and we help customers narrow it down all the time - the BEST way to do that is one-on-one. Get in touch with our team. Otherwise, here's how all three stack up as the best commercial floor sweeper for your facility.

Cleaning Path

The S7 and Terra 28B both sweep 28 inches. The S6 trails at 26. Two inches might sound minor, but the wider path means fewer passes and less time on the floor across an 8-hour shift in a 50,000-square-foot facility. 

Schools, hospitals, or warehouses where the daily task is sweeping long corridors benefit from the wider 28-inch path. The 2-inch cleaning path gap compounds with every run for the Tennant S6 vs Advance Terra 28B comparison specifically. It’s a wash in looking at the S6 vs 28B.

Hopper Capacity

The Advance Terra 28B leads at 15 gallons. It’s 3 gallons bigger than the S7 and nearly 6 gallons more than the S6. Bigger hopper = fewer dump stops during a shift. That directly affects real-world productivity in debris-heavy environments. 

Operations focused on cleaning warehouse floors or any other setting where dust and grit build up fast get the most value from the Terra's extra capacity.

Cleaning Productivity

You need to take productivity ratings with a grain of salt, as brands can skew them based on a number of factors - but here’s what you can generally expect:

• S7 - 28,000 sq ft/hr  
• Terra 28B - 20,000 sq ft/hr
• S6 - 18,750  sq ft/hr

The ACTUAL numbers depend on layout, debris load, and how often you're stopping to dump. It comes down to what your limiting factor is - hopper capacity or battery life.

For instance, the hopper fills before the battery drains in warehouse operations where cleaning starts with sweeping up metal shavings and concrete dust. That narrows the S7's speed advantage. 

The S7 wins in open spaces with light debris. The Terra's bigger hopper wins in heavy-debris runs. You’ll want to think about what your biggest obstacle is to pick between the Tennant S6 and S7 vs Advance Terra 28B. Is it debris itself, or an expansive layout? 

Filtration Features

The S6’s 99.5% filtration efficiency at 2 microns with a self-cleaning shaker can help you maintain indoor air quality. The Terra 28B uses a durable polyester panel filter.

Any of these machines can be a good fit for facilities where dust control is critical, such as healthcare, food processing, or even school floor cleaning. The S6 may have a slight edge on paper.

Noise Levels

The Terra 28B runs at 59 dBA. The Tennant machines measure around 61 dBA. It’s a subtle difference, but it matters when comparing the Tennant S7 vs Advance Terra 28B for operations where cleaning happens while others are present in the building.

For example, the Terra has a slight edge for hospital floor cleaning and office environments where patient or employee disruption is a concern.

Size and Storage

All three are walk-behind machines, but hopper and path width create noticeable size differences. The S6's 26-inch path and 9.3-gallon hopper make it the most compact. It’s easier to store in tight maintenance closets. 

Meanwhile, the S7 and Terra 28B share a 28-inch footprint. The difference is the Terra's 15-gallon hopper. It’s bulkier than the S7's 12-gallon hopper. The Tennant S6 vs Advance Terra 28B size difference is worth factoring in if equipment storage is tight.

Cost Considerations

You get what you pay for, so don’t make the decision based on cost alone. That said, the numbers say a lot. The S6 is the budget pick at $3,628. But, it's manual drive with the smallest hopper. 

The Terra 28B costs $5,967 - that’s over $1,200 less than the S7 at $7,251, while matching or exceeding it on hopper capacity and warranty! The S7 has the highest productivity rating and longest battery runtime, though.

The Tennant S7 vs Advance Terra 28B cost question really comes down to whether the S7's speed advantage is worth the extra money and 2 fewer years of warranty coverage. Speaking of which…

Warranty and Support

This is the biggest gap in the entire Tennant S6 and S7 vs Advance Terra 28B comparison. Both Tennants carry 1-year parts, 1-year labor, 1-year prorated battery, and 3 months of technician travel. 

The Terra 28B triples the core coverage: 3-year parts, 3-year labor, 1-year prorated battery, and a full year of technician travel. Warranty length directly affects the total cost of ownership of machines at this price. A repair in year 2 is covered on the Terra and fully out-of-pocket on either Tennant.

Wrapping Up Our Tennant S6 and S7 vs Advance Terra 28B Comparison

All three machines have their place in the commercial cleaning world, but only one is right for your facility. We hope this comparison guide has left you feeling clear on which one that is.

The S6 keeps costs down at $3,628 with manual drive and strong filtration. Solid pick for smaller facilities on a budget. The S7 covers the most ground per hour and runs 3 hours on a charge. But it’s expensive at $7,251, and may not earn its price in comparison to the Advance sweeper. 

The Terra 28B hits the middle at $5,967 with the biggest hopper, quietest operation, and a 3-year warranty. We carry all three and stock parts for each brand.
