Powered by a robust 20V lithium-ion battery system, this unit frees operators from the spatial limits of wall outlets, allowing for rapid deployment across expansive warehouses, active construction sites, and multi-story facility maintenance routes. The exterior features a cool, polished stainless steel tank that resists impacts and harsh environmental elements, housing a specialized motor capable of handling both liquid spills and solid debris. Available in 15L, 18L, and 20L capacities, it strikes an optimal balance between payload volume and maneuverability. Whether your crew is extracting fine dust from workshop floors or managing sudden liquid overflows in a commercial kitchen, this cordless vacuum cleaner combines immediate readiness with sustained operational power, ensuring your workspace remains immaculate without the tripping hazards of traditional corded equipment.


20L Portable Li-ion Wet Dry Vacuum Cleaner with 20V battery for commercial and industrial cleaning


Functionality

Cordless Freedom with Lithium-ion Power

The core of this system is the 20V lithium-ion battery, designed to support an expansive ecosystem of compatible tools. By utilizing a universal battery interface, facility crews can swap power sources seamlessly, dramatically reducing equipment downtime. The satisfying click of the battery locking into place signals immediate readiness, delivering consistent voltage for uninterrupted suction. This cordless architecture accelerates daily routines, allowing operators to navigate complex layouts—from dense storage aisles to fleet vehicle interiors—without managing tangled cables or searching for power sources.

Dual Wet & Dry Cleaning Performance

Engineered for unpredictable messes, the system transitions instantly between dry extraction and liquid recovery. The leak-proof stainless steel tank safely contains heavy fluids, while the protective foam filter and specialized dust collection bag capture fine particulates. For environments requiring stringent occupational health standards, the filtration system effectively traps airborne debris, supporting better indoor air quality for workers. From absorbing accidental water pooling to gathering coarse wood shavings, the dual-action performance handles diverse materials efficiently.

Versatile Blowing Function

Beyond suction, the unit features an integrated blowing function that expands its utility across outdoor and complex indoor spaces. By simply relocating the hose, operators can generate a concentrated airstream to dislodge debris from intricate machinery, clear fallen leaves from loading docks, or expel dust from tight, unreachable corners. This dual-mode capability transforms the vacuum into a comprehensive site maintenance tool.

Precision Cleaning Accessories

Every unit arrives with a carefully curated toolkit to address specific surface challenges. The standard package includes a flexible 32mm suction hose stretching 1.5 meters, providing excellent reach. Three rigid extension pipes allow operators to clean overhead vents or deep under shelving without bending. A narrow crevice nozzle targets tight gaps in vehicle seating or machinery, while the combi-attachment glides smoothly over both carpeted office areas and bare concrete floors, ensuring comprehensive coverage.

Characteristic Advantages

Portable & Lightweight Design

Despite its substantial capacity, the 805-20L maintains an impressively low physical footprint. The ergonomic carry handle distributes weight evenly, reducing operator fatigue during extended shifts or when navigating stairwells. Furthermore, the internal motor housing features specialized shock-absorbing and noise-reduction materials. This dampens the operational sound to a manageable low hum, ensuring compliance with noise restrictions in occupied commercial buildings or quiet zones, protecting both the operator and surrounding personnel.

Durable Stainless Steel Tank

The main containment vessel is constructed from 0.4mm-thick stainless steel, providing exceptional defense against dents, punctures, and corrosive liquids. Unlike plastic alternatives that absorb odors over time, the smooth metallic interior wipes clean effortlessly, preventing bacterial buildup. This washable, bagless-capable design significantly lowers consumable expenses and simplifies daily maintenance, contributing to a highly favorable Total Cost of Ownership (TCO) for large-scale operations.

Space-Saving Accessory Storage

Efficiency extends to the physical storage of the unit itself. An intelligently molded accessory mount securely grips the extension wands, nozzles, and hose directly on the chassis. This integrated organization prevents tools from being misplaced in busy utility closets or transit vehicles, ensuring that cleaning crews always have the required attachments on hand for immediate deployment.

Long-Lasting Battery Life

The advanced lithium-ion cells deliver sustained, fade-free power throughout their discharge cycle. Designed for rigorous daily use, the battery supports rapid recharging protocols to keep operations moving. Because the power pack is fully removable, facilities can maintain a rotating inventory of charged batteries (sold separately), enabling continuous, round-the-clock cleaning schedules without waiting for a single unit to recharge.

FAQ

How long does the lithium-ion battery last on a single charge?

The battery provides 20-30 minutes of continuous, fade-free runtime, which is highly optimal for targeted spot-cleaning, vehicle fleet detailing, or managing sudden spills in high-traffic areas. Actual operational time may vary slightly depending on the density of the debris and whether the unit is pulling heavy liquids or light dust.

Can it clean wet messes like spilled milk?

Yes, the system is fully equipped for liquid recovery. Simply remove the dry dust collection paper bag, ensure the protective foam filter is securely attached over the motor intake, and vacuum liquid spills directly into the leak-proof stainless steel tank. The 0.4mm steel walls resist corrosion from most common commercial liquids, ensuring safe extraction.

Is the suction strong enough for pet hair?

Absolutely. Driven by a specialized 20V motor, the vacuum achieves a vacuity of ≥8KPa, generating powerful lift. This easily extracts embedded pet hair, heavy dirt, and coarse debris from carpeted surfaces, upholstery, and commercial vehicle seats. The included combi-attachment features textured bristles that enhance grip on stubborn fibers.

How long does it take to charge the battery?

The lithium-ion power pack fully replenishes in just 3-4 hours using the standard charging dock. A clear LED charging indicator light communicates the battery's status, letting your crew know exactly when the unit is ready for deployment. For continuous operations, we recommend keeping a secondary battery on the charger to eliminate downtime entirely.
