Nilfisk Aero 26-21 PC
Best OverallPros
- Self-cleaning filter reduces maintenance
- HEPA 13 certified for fine dust
- Powerful 1400W motor for heavy debris
Cons
- Heavier than some competitors
- Hose storage could be better
The Nilfisk Aero 26-21 PC is the flagship model in the 2026 range, designed for users who need reliable wet and dry vacuuming with minimal downtime. Its self-cleaning filter system automatically shakes off dust during operation, maintaining strong suction even when collecting fine particles. Owner reviews consistently highlight the build quality and the effective HEPA 13 filtration, which makes it suitable for workshops handling wood dust or drywall debris.
With a 26-litre tank and 1400W motor, it handles large spills and construction site cleanup without frequent emptying. The blow function adds versatility for clearing leaves or dust from tight spaces. The main drawbacks are its weight at 12 kg and the lack of integrated hose storage, though the included accessories cover most tasks well.
Nilfisk Buddy II 18
Best BudgetPros
- Compact and lightweight at 7.5 kg
- Good value for money
- Easy to carry and store
Cons
- No HEPA filter option
- Smaller capacity for large jobs
The Nilfisk Buddy II 18 is the entry-level model that still delivers solid performance for home workshops and DIY tasks. Its 1200W motor provides enough suction for sawdust, small debris, and liquid spills, while the 18-litre tank is adequate for most weekend projects. Owner reviews praise its portability and simple operation, making it a popular choice for those new to shop vacs.
The cartridge filter is washable and easy to maintain, though it does not capture ultra-fine particles as effectively as HEPA models. The lack of a blow function and a shorter hose limit its versatility compared to larger units. For light to medium use, however, the Buddy II 18 offers reliable performance at a budget-friendly price point.
Nilfisk Aero 21-21
Best Mid-RangePros
- Automatic filter cleaning system
- Good balance of size and power
- Durable metal latches
Cons
- HEPA filter sold separately
- Hose diameter limits some attachments
The Nilfisk Aero 21-21 sits between the compact Buddy and the large Aero 26, offering a 21-litre tank with a 1300W motor. Its standout feature is the automatic filter cleaning mechanism, which pulses air through the filter to maintain suction during dusty jobs. This makes it a strong contender for workshops that generate moderate amounts of fine dust without the premium cost of the top model.
Owner reviews note the robust construction, with metal latches and a sturdy trolley base that makes moving it around easy. The lack of a HEPA filter out of the box is a minor drawback, though an upgrade is available. The 35mm hose works well for standard debris but may not fit larger power tools directly.
Nilfisk Aero 30-21
Best Large CapacityPros
- 30-litre tank for fewer empties
- Integrated blow function
- Powerful suction for heavy debris
Cons
- Bulky and heavy at 14 kg
- No HEPA filter option
The Nilfisk Aero 30-21 is designed for users who need maximum capacity for large-scale cleanup tasks. Its 30-litre tank and 1400W motor allow it to handle construction debris, large spills, and workshop waste without frequent stops. The built-in blow function adds versatility for clearing outdoor areas or drying surfaces.
Owner reviews highlight the sturdy wheels and trolley handle, which make it manageable despite its weight. The cartridge filter is effective for general dust but does not meet HEPA standards, so it is less suitable for fine particulate work. The larger footprint also requires more storage space. For heavy-duty jobs where capacity is key, this model delivers.
Nilfisk Aero 15-11
Best CompactPros
- Very compact and lightweight at 6 kg
- Easy to carry and store
- Good for small spills and car interiors
Cons
- Less powerful than larger models
- Small tank requires frequent emptying
The Nilfisk Aero 15-11 is the smallest model in the Aero series, aimed at users who need a portable vacuum for light tasks. Its 1100W motor is adequate for sawdust, crumbs, and liquid spills, while the 15-litre tank suits small workshops or home use. Owner reviews appreciate its easy handling and the ability to store it in tight spaces.
The cartridge filter is simple to clean, but the vacuum lacks the advanced filtration of larger models. The shorter hose and smaller wheels limit its use on rough surfaces. For those who prioritise portability over power, the Aero 15-11 is a practical choice for quick cleanup jobs.
What to check before buying a Nilfisk shop vac
Capacity is the first consideration. A 15-litre tank suits light home use, while 26 to 30 litres is better for workshops and construction sites. Motor power typically ranges from 1100W to 1400W, with higher wattage providing stronger suction for heavy debris. Filtration is critical for fine dust: HEPA 13 filters are essential for woodworking or drywall cleanup, while cartridge filters work for general messes. Check the hose diameter, as larger hoses handle bigger debris but may not fit all power tools. Weight and portability matter if you move the vac frequently. Finally, consider accessories like crevice tools, floor nozzles, and blow functions that add versatility.
Mistakes to avoid when choosing a shop vac
One common mistake is buying a model with insufficient capacity for your typical job size, leading to frequent emptying. Another is overlooking filtration needs: using a standard filter for fine dust can clog quickly and reduce suction. Do not ignore hose compatibility with your tools, as some power tools require specific adapters. Avoid choosing solely on price without considering build quality, as cheaper models may have flimsy latches or wheels. Finally, do not forget to check the noise level, as some shop vacs can be loud in enclosed spaces.
