The tank is made from impact-resistant polypropylene, which resists cracking on job sites. The 2.5-metre hose gives decent reach for deck areas. Some users note the weight at nearly 12 kg, but the wheels and handle make rolling it across the deck manageable.

Owner reviews note its quiet motor and easy manoeuvrability. The smaller capacity means you will need to empty it more often on larger decks. It is best suited for small to medium decks where storage space is limited.

Bosch GAS 15
Best for Fine DustPros
- Excellent HEPA filtration
- Automatic filter cleaning
- Good suction for wet and dry
Cons
- Higher price point
- Filter cleaning can be noisy
The Bosch GAS 15 is a premium shop vac with advanced filtration. It features a 15-litre tank and 5 peak horsepower, along with an automatic filter cleaning system that keeps suction strong. It is ideal for decking projects that involve sanding or sawing.
Owner reviews praise its HEPA filter for capturing fine dust particles, which is useful if you are refinishing the deck. The automatic cleaning reduces maintenance. It is a more expensive option but offers superior air quality and suction consistency.
What to check before buying a shop vac for decking
Wet capacity: Look for a tank size of at least 12 litres. Larger decks produce more standing water, so a bigger tank reduces how often you need to empty it.
Suction power: Peak horsepower ratings between 4 and 5.5 are common. Higher HP means faster water pickup, which is important for preventing water damage to wood.
Filtration: A wet/dry filter is essential. For deck sanding projects, consider a HEPA filter to trap fine dust particles and keep the air clean.
Portability: Wheels and a handle make rolling the vac across the deck easier. If you have stairs, a lighter model under 10 kg may be preferable.
Hose length: A hose of at least 2 metres gives you reach without moving the unit. Longer hoses reduce the need to reposition frequently.
Mistakes to avoid when using a shop vac on your deck
Using a dry filter for wet pickup: Always switch to a wet filter or remove the paper filter before vacuuming water. A wet paper filter will clog and damage the motor.
Overfilling the tank: Stop when the liquid reaches the float valve. Overfilling can cause water to enter the motor and ruin the vac.
Neglecting to empty after use: Leaving water in the tank can lead to mould and odours. Empty and rinse the tank after each deck cleaning session.
Using the wrong accessories: A wide floor nozzle works best for flat deck surfaces. Using a narrow crevice tool slows down water pickup.
