Nilfisk Buddy II 18V
The best cordless wet-dry vac for portability and convenience.
Nilfisk Buddy II 18V
Best For PortabilityPros
- Very lightweight and portable
- Cordless convenience
- Good suction for small debris
Cons
- Small tank capacity
- Battery and charger sold separately
The Nilfisk Buddy II 18V is a compact, cordless wet-dry vacuum designed for quick cleanups in the car, workshop, or home. It uses the same 18V battery platform as Nilfisk's cordless pressure washers, making it a good addition if you already own other Nilfisk tools. Owner reviews consistently praise its portability and ease of use, noting it is ideal for picking up dust, crumbs, and small spills.
However, its 5-liter tank is small, and it is not suited for large-scale liquid collection or heavy construction debris. The suction power is adequate for light-duty tasks but falls short of corded models. It is best viewed as a convenient dustbuster-style vac rather than a primary workshop vacuum.
Nilfisk Multi 30
Best For Workshop UsePros
- Very powerful suction
- Large 30L tank
- Durable build quality
Cons
- Heavy and bulky
- Noise level is high
The Nilfisk Multi 30 is a corded wet-dry vacuum built for serious workshop use. Its 1200W motor provides strong suction for both wet and dry debris, and the 30-liter tank means fewer stops to empty. Owner reviews highlight its robust construction and reliability, with many users noting it handles fine dust and larger debris equally well.
On the downside, it is heavy and noisy, making it less suitable for home use or quiet environments. The hose and accessories are functional but not premium. It is a straightforward, no-frills workhorse that gets the job done.
Nilfisk Buddy II 18V (with Battery Kit)
Best Value BundlePros
- Complete kit out of the box
- Same great portability
- Good value if you need a battery
Cons
- Still a small tank
- Battery platform is limited
This version of the Buddy II comes with a battery and charger, making it a true ready-to-use package. For users who do not already own Nilfisk 18V tools, this bundle avoids the extra cost of buying a battery separately. Owner feedback is positive, with many appreciating the convenience of having everything in one box.
The trade-off is that you are locked into the Nilfisk 18V ecosystem, which is less extensive than brands like DeWalt or Makita. However, if you only need a cordless vac, this is a solid, hassle-free option.

Nilfisk Multi 20
Best Mid-Range CordedPros
- Good balance of power and size
- Lighter than the Multi 30
- Quieter operation
Cons
- Less suction than Multi 30
- Hose could be longer
The Nilfisk Multi 20 sits between the compact Buddy and the large Multi 30. It offers a 20-liter tank and 1000W of power, making it suitable for medium-duty workshop tasks and home garage use. Owner reviews note it is noticeably quieter than the Multi 30, which is a plus for residential areas.
It handles wet pickup well, but some users report the hose length is a bit short for larger spaces. It is a good middle-ground option for those who need more capacity than the Buddy but do not want the bulk of the Multi 30.

Nilfisk Multi 50
Best For Heavy DutyPros
- Maximum suction power
- Very large tank capacity
- Industrial-grade durability
Cons
- Extremely heavy
- Very loud
The Nilfisk Multi 50 is the largest and most powerful model in the range. With a 1500W motor and 50-liter tank, it is designed for professional workshops and construction sites. Owner reviews from tradespeople praise its ability to handle large volumes of debris and liquid without losing suction.
However, it is heavy, loud, and takes up significant space. It is overkill for home use and is best suited for those who need a commercial-grade machine. The accessories are robust, but the price is also significantly higher than other models.
| Model | Best For | Key Spec | Rating | Price |
|---|---|---|---|---|
| Buddy II 18V | Portability | 5L, 18V | 4.5/5 | Mid |
| Multi 20 | Mid-Range Corded | 20L, 1000W | 4.2/5 | Mid |
| Multi 30 | Workshop Use | 30L, 1200W | 4.3/5 | High |
| Multi 50 | Heavy Duty | 50L, 1500W | 4.1/5 | Very High |
Who is a Nilfisk Wet Dry Vacuum For?
Nilfisk wet-dry vacuums are best suited for users who already own Nilfisk pressure washers or other tools in their ecosystem. The Buddy II 18V is ideal for car owners, DIYers, and homeowners who need a portable vac for quick cleanups. The corded Multi series targets workshop owners and tradespeople who require consistent, powerful suction for longer periods.
Performance and Suction Power
Performance varies significantly across the range. The cordless Buddy II offers around 60 CFM, which is sufficient for dust, crumbs, and light liquid spills. The corded models, particularly the Multi 30 and Multi 50, deliver 200-240 CFM, making them capable of handling sawdust, gravel, and standing water. Owner reviews consistently note that the corded models maintain suction well even as the tank fills, a key advantage over some competitors.
Build Quality and Durability
Nilfisk builds their vacuums with a focus on durability. The Multi series features robust plastic tanks and metal latches, while the Buddy II uses a lighter but still sturdy construction. Warranty terms vary by region, but Nilfisk generally offers 2-3 years on their vacuums. Aggregated owner reviews indicate few long-term reliability issues, with most complaints centered on accessory quality rather than the motor or tank.
Alternatives to Nilfisk Wet Dry Vacuums
If Nilfisk does not fit your needs, consider the Karcher WD series for similar build quality and a wider accessory range. For those on a budget, the Stanley wet-dry vacs offer good value. If you are invested in a different battery platform, such as DeWalt or Makita, their respective cordless shop vacs may be a better ecosystem fit.
What to Check Before Buying a Nilfisk Wet Dry Vacuum
Consider the primary use case. For car detailing and home cleanups, the Buddy II is ideal. For workshop dust extraction, a corded Multi model is necessary. Check the included accessories, as some models come with more attachments than others. Also, verify the battery compatibility if opting for the cordless model, as Nilfisk's 18V platform is not as widespread as other brands.
Mistakes to Avoid
Do not buy the Buddy II expecting it to replace a full-sized shop vac for heavy construction debris. Avoid purchasing the Multi 50 for home use, as its size and noise level are excessive. Also, be aware that the Buddy II often ships without a battery, so factor in that cost unless you buy the bundle.
