The Tornado Zephyr (Model TV570-Q03-U) is the lightest commercial cordless backpack vacuum in the Tornado lineup — weighing under 11.5 lbs with the battery installed. That figure is lighter than most corded commercial backpack vacuums and dramatically lighter than any other cordless backpack at this performance level. The weight is achieved through the expanded polypropylene (EPP) body — the same impact-absorbing, lightweight material used in protective sports equipment and automotive safety components — combined with a compact brushless DC 2-stage motor delivering 75 CFM and 75″ waterlift. H14 HEPA filtration exceeds US HEPA standards. Deuter Aircomfort harness with five-point adjustment. Belt-mounted controls with ECO mode and real-time battery indicator. Up to 73 minutes of runtime in ECO mode on the 36V battery. Hose position adjusts for right- or left-handed operators. Telescoping wand, floor tool, and crevice tool included. 4-year parts / 2-year labor / 1-year battery warranty.

Key Features of the Tornado Zephyr
Under 11.5 lbs With Battery — The Lightest Commercial Cordless Backpack
The Zephyr’s 11-lb weight with battery is its defining operational advantage. Context: the corded Tornado Pac-Vac 6 Aircomfort weighs 13 lbs. The Pac-Vac 6 Roam (the other cordless Tornado backpack) weighs 25 lbs. The Zephyr weighs less than the corded unit and less than half the Roam — while delivering a brushless motor with higher CFM and waterlift than the Roam’s brushed motor. For operators cleaning multi-floor facilities over full shifts, a 3-lb difference from the corded Aircomfort is negligible; the gain is cord freedom. Against the Roam’s 25-lb carry, the Zephyr’s 11 lbs is the choice for operators where backpack weight fatigue over a sustained shift is the primary ergonomic concern.
Expanded Polypropylene (EPP) Body — Lightweight and Impact-Resistant
Expanded polypropylene is a closed-cell foam material — the same material used in motorcycle helmets, bicycle helmets, and automotive bumper cores — that achieves high structural rigidity and impact resistance at very low density. Applied to the Zephyr’s body, it delivers a shell that resists the drops, wall contacts, and daily handling of commercial cleaning use without the weight penalty of injection-molded plastic or ABS housings used in conventional backpack vacuums. The EPP construction is what allows the Zephyr to weigh under 11.5 lbs with a 36V battery installed — a weight figure that simply isn’t achievable with conventional backpack body materials at this motor size.
Brushless DC 2-Stage Motor — 75 CFM / 75″ Waterlift
The brushless DC 2-stage motor delivers 75 CFM and 75″ waterlift — the highest suction specs in the Tornado cordless backpack lineup. Brushless motor design eliminates carbon brushes, reducing maintenance costs and extending motor service life compared to brushed motor designs. The 2-stage motor configuration uses two fan stages in series, achieving higher waterlift from the battery power budget than a single-stage motor at equivalent current draw. At 75 CFM and 75″ waterlift, the Zephyr provides effective carpet maintenance vacuuming across commercial loop pile and cut pile in the daily cleaning pass applications where backpack vacuums are typically deployed.
H14 HEPA Filtration — Exceeds US Standards
The Zephyr’s 2-stage filtration system uses a fleece bag for primary capture and an H14 HEPA exhaust filter. H14 is the European HEPA classification above the US HEPA standard — H14 specifies 99.995% filtration efficiency at 0.3 microns, compared to the US HEPA standard of 99.97%. For facilities with strict indoor air quality requirements — healthcare, cleanrooms, education — the H14 designation provides a higher documented filtration standard than standard HEPA equipment. The sealed 2-stage system ensures all exhaust air passes through the H14 filter before returning to the room.
The belt-mounted control panel puts all functions at the operator’s hip — power switch, ECO efficiency mode selector, and real-time battery runtime indicator — accessible without removing the backpack or reaching back to the unit. In commercial cleaning workflows where operators transition continuously between spaces and floor types, belt-mounted controls allow instant ECO/Power switching for runtime management without interrupting the cleaning pass. The battery indicator shows remaining runtime at a glance, allowing the operator to plan outlet-independent transitions accurately without an unexpected battery depletion mid-room.
Right- or Left-Handed Hose Position Adjustment
The suction hose position adjusts for right- or left-handed operators — the hose exits the backpack body from the side that matches the operator’s dominant hand, routing the hose naturally to the working hand without crossing the body. In a commercial cleaning program where multiple operators share machines across shifts, the quick position adjustment ensures each operator’s ergonomic preference is met without tool changes or machine reassignment.
Deuter Aircomfort Harness — 5-Point Adjustment
The Deuter Aircomfort harness uses the same tensioned mesh back panel and five-point adjustment system as the corded Pac-Vac Aircomfort and Pac-Vac 6 Roam — air channels between the operator’s back and the vacuum body, escaping from three sides and reducing perspiration by up to 25% compared to closed-back designs. At 11 lbs, the Zephyr’s carry load is minimal — the harness system at this weight is primarily about fit and comfort over a shift rather than load distribution. The five-point adjustment fits the machine to different operator body sizes for a secure, non-shifting carry during cleaning passes.
73-Minute ECO Runtime — Same 36V Battery Platform as Strike and Tempest
The Zephyr runs up to 73 minutes in ECO mode on the 36V 7.5Ah lithium-ion battery (K24450750) — the longest ECO runtime in the Tornado cordless line. The same battery is interchangeable across the Tornado Strike (TV190-W10-U), Tempest (TV400-W26-U), and Zephyr — one battery platform services the entire Tornado cordless machine fleet. For operations running multiple Tornado cordless machines, a single battery inventory covers all three models with one charger (K24450530).
Complete Tool Set — Telescoping Wand, Floor Tool, Crevice Tool
The Zephyr includes a telescoping wand (adjustable length for operator height without separate wand sections), floor tool for carpet and hard floor cleaning passes, and crevice tool for baseboards, corners, and tight spaces. The telescoping wand adjusts to operator height in a single component — no 2-piece assembly required, reducing setup time between uses.
Required Accessories — Battery and Charger
The Zephyr ships as the vacuum unit with tools only. To operate it you need the battery and charger, both sold separately:
Maximum suction, corded reliability, lighter carry than Roam
Choose the Zephyr when operator weight comfort is the priority and cordless operation is required — it’s the lightest backpack in the lineup with the strongest suction of the two cordless options. Choose the Roam when hot-swap battery capability is required for continuous multi-hour operation without a charging stop. Choose the corded Aircomfort when maximum suction (110 CFM / 110″) and lighter carry than the Roam matter more than cord freedom.
Hotels and hospitality — guest room carpet and hard floor daily maintenance; ultra-light carry for housekeeping staff on multi-floor routes; 73-min ECO runtime covers extended corridor cleaning between charges
Healthcare — H14 HEPA filtration exceeds US standards for IAQ-sensitive patient and administrative areas; lightweight carry reduces operator fatigue during full-shift cleaning programs; cordless for infection-control-compliant room-to-room operation
Education — classroom and corridor carpet maintenance; lightweight for staff who clean multiple classrooms per shift; H14 HEPA for student IAQ
Office buildings — open-plan carpet and hard floor maintenance during occupied hours; cordless eliminates outlet routing across workstations
Cleanrooms and controlled environments — H14 HEPA exceeding US standards is the relevant specification for cleanroom-adjacent or controlled-environment cleaning applications
Building service contractors — multi-building operations where operator fatigue across full shifts is a program management concern; the lightest cordless commercial backpack available at this suction level
Retail — store carpet and hard floor maintenance during open hours; cordless eliminates customer trip hazard; lightweight for staff carrying the unit between stockroom and sales floor

How does the Zephyr compare to the Pac-Vac 6 Roam?
The Zephyr is 14 lbs lighter (11 vs 25 lbs), uses a brushless motor vs brushed, delivers higher CFM and waterlift (75/75 vs 70/65), and has H14 HEPA exceeding US standards vs 4-stage HEPA. The Roam’s advantage is hot-swap battery capability — the battery swaps without removing the unit, enabling continuous operation across shifts with multiple batteries. The Zephyr requires removing the unit to swap batteries. For maximum weight reduction, the Zephyr wins. For uninterrupted long-shift operation, the Roam wins. Shop the Pac-Vac 6 Roam →
What is expanded polypropylene (EPP) and why does it matter?
EPP is a closed-cell foam material used in protective applications — helmet liners, automotive bumpers — that achieves high structural rigidity and impact resistance at very low density. On the Zephyr, it produces a body that weighs a fraction of conventional backpack plastic housings while meeting the impact resistance demands of commercial cleaning use. It’s the primary reason the Zephyr weighs under 11.5 lbs with the battery installed.
What does H14 HEPA mean vs standard HEPA?
Standard US HEPA filters at 99.97% efficiency at 0.3 microns. H14 is a European classification filtering at 99.995% efficiency — capturing more fine particles per pass through the exhaust filter. For facilities with strict IAQ documentation requirements, H14 provides a higher certified filtration standard than equipment meeting US HEPA minimums.
Can I use the Zephyr battery in the Tornado Strike?
Yes — the 36V 7.5Ah battery (K24450750) is interchangeable across the Zephyr (TV570-Q03-U), Strike (TV190-W10-U), and Tempest (TV400-W26-U). One battery and one charger service all three machine types.
