Karcher WD 3
Best OverallPros
- Excellent build quality and brand reputation
- Strong suction for both wet and dry debris
- Easy to empty and clean tank
Cons
- Hose could be longer
- Noisy at full power
The Karcher WD 3 is a benchmark in the budget wet dry vacuum category. With a 1000W motor and a 17-litre capacity, it handles everything from sawdust in the workshop to spilled water in the garage. Owner reviews consistently praise its reliability and strong suction, making it a favourite for DIYers and professionals alike.
Its robust build and simple design mean fewer things to go wrong. The included accessories are practical, and the blower function adds versatility. While it is a corded model, the performance justifies the tether, and it remains one of the most recommended models under £100.
Einhell TE-VC 18/20 Li
Best CordlessPros
- Full cordless freedom for outdoor use
- Large 20-litre capacity
- Part of the Power X-Change ecosystem
Cons
- Battery and charger sold separately
- Suction slightly less than corded models
The Einhell TE-VC 18/20 Li is perfect for those who need mobility. It runs on Einhell's Power X-Change battery platform, meaning you can share batteries with other tools. With a 20-litre tank, it is surprisingly large for a cordless vacuum, making it ideal for cleaning cars, patios, and garages without a power outlet nearby.
Owner feedback highlights its convenience and decent suction for a battery-powered unit. It is not as powerful as a corded vacuum, but the trade-off for portability is well worth it for many users. The build quality is solid, and it represents excellent value for a cordless wet dry vacuum under £100.
Bosch UniversalVac 15
Best CompactPros
- Very compact and easy to store
- Integrated accessory storage
- Quieter operation than many rivals
Cons
- Lower power than some competitors
- Smaller 15-litre capacity
The Bosch UniversalVac 15 is designed for users who value space. Its compact footprint and clever accessory storage make it a great choice for small workshops or apartments. Despite its smaller 620W motor, it still provides ample suction for everyday spills and dust, and many owners note it is quieter than expected.
This model is ideal for light to medium-duty tasks. It handles wet and dry pickups well, and the Bosch build quality is reassuring. If you need a vacuum that tucks away easily and doesn't take up much room, the UniversalVac 15 is a strong contender under £100.
Stanley SL18116P
Best Budget ValuePros
- Very affordable price point
- Powerful 1200W motor
- Includes blower function
Cons
- Plastic feels less premium
- Hose can be stiff
The Stanley SL18116P is a budget champion. It offers a powerful 1200W motor and a 16-litre capacity at a price that undercuts most competitors. Owner reviews are generally positive, with many praising its suction power for the cost. It also features a blower function, adding versatility for clearing leaves or sawdust.
While the build quality is not as refined as the Karcher or Bosch, it is more than adequate for occasional use. The plastic components feel a bit cheaper, but for the price, it is hard to argue with the performance. If you need a capable wet dry vacuum on a tight budget, the Stanley is a solid choice.
Sealey 600/2
Best for Workshop UsePros
- Stainless steel tank for durability
- Lightweight and portable
- Good for fine dust and liquids
Cons
- Smaller 12-litre capacity
- Lower power than some
The Sealey 600/2 is a tough little vacuum built for workshop environments. Its stainless steel tank is more resistant to dents and impacts than plastic alternatives. With a 600W motor and 12-litre capacity, it is best suited for smaller cleanups and fine dust collection. It is also very lightweight, making it easy to carry around.
Owner reviews appreciate its robust construction and reliable performance. It is not the most powerful or largest, but it is built to last. For a dedicated workshop vacuum that can handle occasional wet spills, the Sealey 600/2 is a dependable choice under £100.
What to Check Before Buying a Wet Dry Vacuum Under £100
Power (Watts): Higher wattage usually means stronger suction. Look for at least 600W for effective wet and dry pickup. Cordless models rely on voltage (18V or 20V) and battery amp-hours.
Capacity (Litres): A larger tank means fewer stops to empty. For home use, 12-17 litres is a good range. If you plan to collect large amounts of water, consider a bigger tank.
Build Quality: Stainless steel tanks are more durable than plastic. Check for sturdy castors and a reliable hose attachment system. Brand reputation matters for long-term reliability.
Accessories: Most models include a crevice tool and floor nozzle. Some include a blower function or a cartridge filter that is easy to clean. Ensure replacement filters are readily available.
Mistakes to Avoid When Buying a Wet Dry Vacuum
Ignoring the filter: A poor filter can clog quickly and reduce suction. Look for a washable or easy-to-replace cartridge filter. Foam filters are better for wet pickup.
Buying a model with a short hose: A short hose limits reach. A 2-metre hose is standard, but longer is better for cleaning cars or high shelves. Check the hose diameter as well.
Forgetting about noise: Wet dry vacuums can be loud. If noise is a concern, look for models with lower decibel ratings or quieter motor technology.
