A Complete Buyer's Guide to the Best Commercial Wet and Dry Vacuum Cleaners

A wet and dry vacuum cleaner picks up liquid spills and dry debris in one machine, so you do not need a separate wet vacuum and dry vacuum on site. For a plumber with a flooded bathroom, a tradie with slurry and sawdust, a hotel with a kitchen spill or a factory with mixed dust and liquid waste, the right model clears the job in one pass and the wrong one stalls halfway through.

This guide covers the specifications that matter, how tank size and motor count change what a machine can do, and which of the 18 models in the table below suits which job. All prices are in Australian dollars and include GST.

Choosing the Best Commercial Wet and Dry Vacuum in Australia

What a Wet and Dry Vacuum Does Differently

A wet and dry vacuum has a waterproof tank, a sealed motor housing and filtration designed to handle moisture. A standard vacuum has none of these, and liquid in the motor or filter damages it. In a commercial setting that means one machine can handle water from a burst pipe, sawdust from a cut, cement slurry, food debris and workshop spills without switching equipment.

The trade-off is that a wet and dry vacuum is built around tank volume and airflow, not the fine dust capture of a dedicated HEPA vacuum. If your site generates regulated dust, read the filtration section below before you buy.

Wet and Dry Vacuum Models at a Glance

This table lists the commercial wet and dry models in our range, grouped by tank size. Extraction models, gutter vacuums and the ATEX unit are covered separately further down.

Key Specifications to Compare

Tank capacity sets how long you can work before emptying. Up to 35 litres suits offices, hospitality, workshops and vehicle interiors where you carry the machine. 56 to 77 litres suits facilities with regular spills and plumbing work. 90 litres or more suits flood response, construction and industrial cleaning. Stainless steel tanks resist corrosion and are easier to sanitise, which matters in food service and healthcare, while plastic tanks are lighter and cost less.

Motors and airflow decide how fast the machine moves air and water. Single motors suit light daily use. Twin and triple motors raise airflow and suit heavy or continuous work. The Cleanstar VC90LP-3M, for example, runs three 1,000W motors for 3,000W and 159 litres per second of airflow, against 120 litres per second for the twin-motor VC90LP.

Water lift is measured in millimetres and shows how hard the machine can pull against resistance, such as dense slurry or liquid in a textured surface. The Tennant V-WD-72 is rated at 2,380mm, the Jetwave Dakota 440/90 at 2,282mm and the Delfin MTL802WD and DM3 EL at 2,500mm.

Filtration is the specification most buyers overlook. Foam filters suit liquid pickup, cartridge filters handle fine dry dust and HEPA filtration is used where airborne particle control is a compliance requirement, such as healthcare, aged care and food processing. Silica dust from cutting or grinding concrete, masonry or engineered stone needs compliance-grade filtration, and a standard wet and dry vacuum is not suitable. Read our silica dust workplace guide before choosing a machine for that work.

Power supply is worth checking before you order. Most of the range runs on a standard 240V outlet, but the Tennant V-WD-72 and Delfin DM3 EL need a 15-amp plug, so confirm your socket suits the machine on a large site.

Compact Wet and Dry Vacuums From 11 to 35 Litres

Small and mid-size tanks suit offices, cafes, retail, workshops and detailing, where the machine is carried or wheeled between areas.

• Tennant V-WD-27 ($484) - 27-litre tank, 7.8kg weight and 70 dBA operation, so staff can move it easily and clean during business hours without disturbing customers.
• Cleanstar VC15L ($371) - 15-litre stainless steel tank, 1,000W motor and 7-metre power cable, so a small workshop or office covers a wide working radius from one outlet.
• Cleanstar VC30L ($569) - 30-litre stainless steel tank and 53 litres per second of airflow, so mid-size spills and daily dry cleaning need fewer trips to empty.
• Sprintus Waterking 30L ($748) - 260 mbar of suction at 70 litres per second with 68 dB sound output, so water and debris are picked up thoroughly in places where noise matters.
• Ghibli V-AS9P ($999) - 35-litre tank with a 1,400W motor, so a facility team has more capacity for daily wet and dry cleaning before emptying.

The Ghibli V-ASL7P ($799) is the smallest in the range at 11 litres with 55 litres per second of airflow. The Jetwave Dakota 515 ($748) is a 27-litre entry-level machine for small offices and garages.

Mid-Size Wet and Dry Vacuums From 56 to 62 Litres

A 56 to 62 litre tank is the practical middle ground for plumbers, facility teams and trades who need capacity without the weight of a 90-litre unit.

• Cleanstar VC60L ($799) - 60-litre stainless steel tank, twin 1,000W motors, 106 litres per second of airflow and 250 mbar of suction, so a flooded bathroom or burst-pipe clean-up is cleared without constant emptying and the tank resists corrosion from prolonged water contact.
• Tennant V-WD-62 ($987) - 62-litre tank, dual independent motors, 18.5kg weight and a drain hose, so large spills are cleared and the tank is emptied without lifting it.
• Ghibli V-AS12P-CBN ($1,499) - 56-litre tank, 115 litres per second of airflow and 19kg weight on castor wheels, so construction dust and wet spills are handled on large floors by one operator.

Large Wet and Dry Vacuums From 72 to 90 Litres

Large tanks and multiple motors suit warehouses, construction sites, flood response and industrial cleaning where stopping to empty costs time.

• Tennant V-WD-72 ($1,126) - 72-litre tank, three independent motors with 3,600W combined power, 166.7 litres per second of airflow and 2,380mm of water lift, so heavy debris and large liquid volumes are cleared quickly. The tipping trolley design means one operator empties it without lifting.
• Cleanstar VC90LP-3M ($836) - 90-litre tank with three 1,000W motors, so high-volume water extraction and construction debris move faster than with twin-motor units.
• Cleanstar VC90LP ($789) - the twin-motor 90-litre version with 2,000W and 120 litres per second of airflow, so tradies and flood crews get maximum capacity at the lower price.
• Lavorwash Scirocco ($1,150) and Taurus Pro ($1,990) - 77-litre tanks with twin and triple 1,200W motors respectively, so operators can step up to industrial capacity without premium pricing. The Taurus Pro is rated at 573 m³/h of suction and has a tilt-clean tank.
• Jetwave Dakota 440/90 ($2,486) - 90-litre tank with three motors, 600 m³/h of airflow and 2,282mm of water lift, so job sites, bond cleans and industrial areas have a heavy-duty option from a different supplier.

The Tennant V-WD-72 also carries SANIFILTER antibacterial filtration, treated with silver ions and tested to JIS L 1902:2008 against Staphylococcus aureus and Klebsiella pneumoniae, which suits healthcare, aged care and food-processing sites.

Industrial and Compliance-Grade Wet and Dry Vacuums

When the job involves fine dust, regulated substances or heavy industrial loads, a standard commercial wet and dry vacuum is not enough. Our Delfin range is Italian-made for this work.

• Delfin MTL802WD ($3,329.70) - 80-litre corrosion-resistant steel tank and twin bypass motors with 2,500mm of water lift, so concrete slurry on site, oil and coolant in a workshop and large liquid clean-ups are all handled by one machine.
• Delfin DM3 EL ($4,972) - three motors, 2,500mm water lift, 540 m³/h airflow and a 3m² L-class filter with a 60-litre or 100-litre roll-out steel container, so mixed dust, solids and liquids are collected on a standard 240V single-phase supply with a 15-amp plug.
• Delfin MTL 801 WD EX ATEX ($6,780.40) - 80-litre stainless steel tank, ATEX-rated for classified areas, with an H14 absolute filter as standard, so combustible dust and non-flammable liquids can be collected in the same machine where classified-area equipment is required.

For more on these machines, see the Delfin industrial vacuum range, the ATEX and IECEx vacuum cleaners and our guide to heavy duty vacuum cleaners for industrial use.

Best Wet and Dry Vacuum for Plumbers and Flood Response

Plumbers need to remove standing water quickly, so tank capacity and suction matter more than fine filtration. The Cleanstar VC60L suits most residential and light commercial call-outs, and a 90-litre model such as the VC90LP-3M suits larger water damage jobs. If the job turns into a full structural drying job, see our guide to drying carpets after water damage.

Best Wet and Dry Vacuum for Tradies and Construction

Construction sites mix sawdust, plaster dust, slurry and liquid on the same job. A 60 to 90 litre machine such as the Cleanstar VC90LP or Tennant V-WD-72 handles a full day on site, and the Delfin MTL802WD suits heavier industrial construction. If you cut or grind masonry, concrete or engineered stone, a standard wet and dry vacuum is not suitable for the silica dust, and a compliance-grade industrial vacuum is needed.

Best Wet and Dry Vacuum for Cars and Vehicle Interiors

Detailing needs moisture extraction from seats and carpet after shampooing, crevice tools and a machine you can carry between vehicles. For lighter vehicle cleaning, the Tennant V-WD-27 at 7.8kg is easy to carry. For shampoo and extract work, the extraction models below use a spray pump and recovery in one unit.

Wet and Dry Extraction Vacuums for Carpet and Upholstery

Extraction vacuums add a spray pump so they can wash and recover in one pass. The Ghibli V-M9P ($1,650) and the V-M9P-SET ($1,999) have a 1,200W motor and a 5-bar spray pump. The Cleanstar EX-FACTOR 80 ($1,799) has an 80-litre tank, twin 2,000W motors and a 20-litre solution tank. The Jetwave Storm ($3,014) has a 62-litre stainless steel recovery tank and a 25-litre detergent tank for carpet, upholstery and vehicle interiors.

If carpet and upholstery cleaning is your main work, compare these with the dedicated machines in our carpet and upholstery cleaning machines range.

Corded or Cordless?

Every wet and dry model in this guide is corded. Mains power gives continuous suction for flood clean-up, slurry and all-day use, with no battery to run flat mid-job, and liquid pickup is where a motor works hardest.

We do stock commercial battery vacuums, but they are dry-only machines. The Cleanstar Prostar ($1,099) is a 36V cordless backpack vacuum that comes with four lithium-ion batteries, two running while two charge, so a cleaning team can work a full shift without waiting for a recharge. The Sprintus ERA iGO ($1,599) is a cordless canister vacuum with up to 90 minutes of run time and a 300W motor for offices, schools, hospitals and hotels. See the backpack vacuum cleaners and dry-only vacuum cleaners collections for the full battery range, and our guide to corded vs cordless backpack vacuums for how to choose. Keep a wet and dry vacuum on site for liquid spills.
