DeWalt DXV18S
Best OverallPros
- Excellent suction for wet and dry debris
- Durable polypropylene tank resists dents
- Blower function for clearing leaves
- Includes 2.5m hose and crevice tool
Cons
- Noisy compared to some rivals
- Short power cord (3m)
The DeWalt DXV18S consistently earns high marks from owners for its raw suction power. With a 1200W motor and 100 CFM rating, it handles everything from sawdust in a workshop to standing water in a garage. The 18-litre tank is a practical size for most home and DIY tasks, and the blower function adds versatility for outdoor cleanup.
Build quality is a strong point. The polypropylene tank is tough and resistant to cracking, and the castors are robust. Some users note the noise level is higher than expected, and the 3-metre power cord can be restrictive, but for the price, the performance is hard to beat.
Stanley SL18116P
Best Budget / Large CapacityPros
- Very affordable price point
- Compact and easy to store
- Good suction for the size
- Includes blower function
Cons
- Plastic clips feel fragile
- Noise level is average
The Stanley SL18116P is a fantastic value option. It delivers reliable suction for everyday messes, from workshop dust to car interiors. The 16-litre capacity is generous for its compact footprint, and the blower function is a handy bonus for clearing patios or leaves.
Owner reviews highlight its ease of use and effective performance for the price. The main criticisms are the plastic tank clips, which some users report breaking after extended use, and the noise level which is not exceptional. Overall, it is a solid, budget-friendly workhorse.
Bosch GAS 18V-1
Best CordlessPros
- Fully cordless and portable
- Compact and lightweight
- Great for quick pickups
- HEPA filter included
Cons
- Very small 1L capacity
- Battery and charger sold separately
The Bosch GAS 18V-1 is a compact cordless wet/dry vacuum designed for quick, portable cleanup. It is ideal for small spills, dust from drilling, or car interiors. The HEPA filter is a nice touch for allergy sufferers, and the 18V battery system means it shares power with other Bosch tools.
Owner feedback praises its convenience and suction for its size. The main drawback is the tiny 1-litre tank, which fills quickly with wet debris. It is not a replacement for a full-size shop vac, but as a spot cleaner, it is excellent. Note that the battery and charger are not included in the price.
Karcher WD 3
Best for Wet PickupPros
- Excellent wet pickup performance
- Easy to empty and clean
- Quiet operation for its class
- Good build quality from Karcher
Cons
- Slightly less dry suction than rivals
- Accessories are basic
The Karcher WD 3 is a dedicated wet/dry vac that shines when dealing with liquids. Its 1000W motor is tuned for efficient water pickup, and the 17-litre tank is easy to empty thanks to a wide opening. Owners consistently report it is quieter than many competitors, a real plus for indoor use.
Dry suction is adequate but not class-leading, and the included accessories are fairly standard. However, for tasks like clearing a flooded basement or sucking water from a sink, the WD 3 is a reliable choice. Karcher's reputation for quality is evident in the sturdy construction.
Sealey 2100W
Best Heavy DutyPros
- Very powerful suction
- Large 30L capacity
- Durable build for heavy use
- Good value for the power
Cons
- Heavy and bulky
- Very noisy in operation
The Sealey 2100W is a brute of a shop vac, offering the highest power and capacity in this roundup. With a 2100W motor and 30-litre tank, it is designed for demanding tasks like clearing large amounts of debris from construction sites or heavy workshop cleanup. The suction is genuinely impressive.
Owner reviews confirm its power but note the trade-offs. It is heavy to move around, and the noise level is significant, making ear protection advisable. It is not the best for quick, light jobs, but for those who need serious suction and capacity under £150, it is a strong contender.
What to check before buying a shop vac under £150
Before you commit, consider the following factors to ensure you get the right tool for your needs. The most important specification is suction power, measured in CFM (cubic feet per minute) or air watts. A higher CFM means better performance for both wet and dry pickup. Next, consider the tank capacity, which for home use is typically between 10 and 30 litres. A larger tank means fewer empty cycles but adds weight. Finally, check the included accessories, such as crevice tools, floor nozzles, and hose length. A longer hose increases reach but can reduce suction slightly.
Mistakes to avoid when buying a shop vac
A common mistake is buying a vac with too small a capacity for your typical mess, leading to constant stops to empty the tank. Another is ignoring the noise level, as some models can be extremely loud, which is a problem for indoor use. Also, do not assume a higher wattage always means better suction, as motor efficiency varies. Finally, be wary of models with poor filter systems, as cheap filters clog quickly and reduce performance. Look for washable or HEPA filters for better longevity and air quality.
FAQs
What is the best shop vac under £150 for wet pickup?
The Karcher WD 3 is widely considered the best for wet pickup due to its efficient motor and easy-to-empty tank.
Can I use a shop vac for dust from a sander?
Yes, but you need a vacuum with a good filter, preferably HEPA, to capture fine dust particles. The DeWalt DXV18S is a good choice.
Are cordless shop vacs under £150 worth it?
They are convenient for quick jobs but have limited runtime and capacity. The Bosch GAS 18V-1 is a good option for portability.
How important is CFM vs wattage?
CFM is a more accurate measure of suction performance. Wattage indicates power consumption, not efficiency. Aim for at least 80 CFM.
What size shop vac do I need for a garage?
For a typical garage, a 15-20 litre capacity is ideal. The DeWalt DXV18S (18L) or Stanley SL18116P (16L) are perfect.
Do all shop vacs come with a blower function?
No, not all. The DeWalt and Stanley models in this list include a blower function, which is useful for clearing leaves.
Is a higher wattage motor always better?
Not necessarily. A well-designed 1000W motor can outperform a poorly designed 1500W motor. Focus on CFM and owner reviews.
Can I use a shop vac to clean a car interior?
Yes, a compact model like the Bosch GAS 18V-1 is ideal for car interiors due to its portability and included crevice tool.
How do I maintain a shop vac?
Regularly empty the tank, clean or replace the filter, and check the hose for blockages. Washable filters should be rinsed and dried.
What is the warranty on these shop vacs?
Most brands offer a 1-year warranty. DeWalt and Bosch often provide extended warranties if registered. Check the product page for details.
