Stanley STDCV700
Best OverallPros
- Excellent suction for the price
- Large 20-litre drum
- Includes blower function
Cons
- Hose is a bit stiff
- Noisy at full power
The Stanley STDCV700 is a workhorse that consistently outperforms its price tag. With a 1400W motor, it generates strong suction for both fine dust and larger debris. The 20-litre capacity means fewer trips to empty it, which is great for bigger workshop cleanups.
Owner reviews praise its durability and the included blower function, which turns the vac into a leaf blower. The main drawbacks are the somewhat stiff hose and the noise level, but these are common at this price point. It is a solid, no-nonsense machine.
Bosch GAS 12-25
Best Compact VacPros
- Compact and easy to store
- Good build quality
- Quieter than many rivals
Cons
- Smaller 12-litre capacity
- Price is near the £100 limit
The Bosch GAS 12-25 is a premium-feeling machine in a small package. Its 1200W motor is efficient and quieter than many larger units. The 12-litre capacity is fine for a car interior or small workshop, and the build quality is typical Bosch: solid.
It is ideal if you are short on space but still want a reliable wet/dry vac. The main trade-off is the smaller drum, which means more frequent emptying. It is a top pick for those who prioritise compactness and brand reliability over raw capacity.
Sealey SS20V
Best for Wet PickupPros
- Excellent wet pickup performance
- Durable stainless steel drum
- Good value for money
Cons
- Accessories feel basic
- Blower function is weak
The Sealey SS20V is built for handling liquids. It features a stainless steel drum that resists rust and corrosion, making it a strong choice for clearing flooded areas or sucking up spillages. The 1300W motor provides reliable suction for both wet and dry tasks.
Owner reviews consistently mention its effectiveness at picking up water. The included accessories are functional but not premium. If your primary need is wet pickup, this is a very capable and affordable option.
Draper 64212
Best Budget ChoicePros
- Very affordable price
- Lightweight and portable
- Simple to use
Cons
- Less powerful motor
- Plastic drum feels less durable
The Draper 64212 is the entry-level option for those on a strict budget. It has a 1000W motor and a 15-litre plastic drum. It is light enough to carry around the house or car easily. For light-duty tasks like cleaning sawdust or a car boot, it gets the job done.
It is not built for heavy workshop use or large volumes of water. The plastic drum and less powerful motor are the main compromises. However, for the price, it is a functional and reliable tool for occasional use.
Karcher WD 3
Best Brand TrustPros
- Trusted Karcher brand
- Good filter system
- Decent 17-litre capacity
Cons
- Suction is average for the price
- Accessories can be pricey
The Karcher WD 3 is a well-known model from a leading brand in cleaning equipment. It features a 1000W motor and a 17-litre plastic drum. The filtration system is good, and it is compatible with Karcher's range of accessories, which is a bonus for existing Karcher owners.
While it is a reliable machine, its suction power is not as strong as the Stanley or Sealey options at a similar or lower price. You are paying a premium for the brand name and ecosystem. It is a safe choice for those who value brand consistency.
What to check before buying a shop vac under £100
Choosing the right shop vac involves more than just looking at the price tag. Here are the key factors to consider.
Motor Power (Wattage). This is the main driver of suction. For under £100, you will typically find motors between 1000W and 1400W. A higher wattage generally means better pick-up for heavy debris and liquids.
Drum Capacity (Litres). A larger drum means less frequent emptying. For general use, a 15-20 litre capacity is a good sweet spot. Smaller 10-12 litre drums are fine for cars or small workshops.
Wet and Dry Capability. All the models listed are wet/dry vacs. Check that the filter is easy to remove and clean for wet pickup. A stainless steel drum is better for frequent water use as it resists rust.
Accessories and Hose. Look at what is included. A standard set includes a crevice tool, a floor nozzle, and a dusting brush. A longer hose (2m or more) offers better reach.
Noise Level. Shop vacs are generally loud. Check the decibel (dB) rating if noise is a concern. Models around 75-80 dB are typical for this class.
Mistakes to avoid when buying a cheap shop vac
Avoiding common pitfalls can save you money and frustration.
Ignoring the filter. A cheap, poorly designed filter can clog quickly and reduce suction. Look for a model with a washable or easy-to-replace filter.
Buying too small. A 10-litre vac might seem like a bargain, but you will quickly find yourself emptying it repeatedly on a medium-sized job. A 15-20 litre model is much more practical.
Overlooking the blower function. Many shop vacs can be used as a blower. This is a useful feature for cleaning out a garage or workshop, so it is worth checking if the model includes this.
Focusing only on price. The cheapest model might lack power or durability. Spending a little more on a well-reviewed model like the Stanley STDCV700 offers much better value over time.
FAQs
Can I use a shop vac to pick up water?
Yes, all the models in this guide are wet/dry vacs designed for liquids. You must remove or use the correct filter for wet pickup to avoid damage.
What is the best shop vac under £100 for car cleaning?
The Bosch GAS 12-25 is a top choice due to its compact size and good suction, making it easy to manoeuvre inside a car. The Stanley STDCV700 also works well if you have space for a larger unit.
Is a more expensive shop vac always better?
Not always. Models like the Stanley STDCV700 offer excellent performance for a low price. However, more expensive models often have better build quality, quieter motors, or better filtration.
How do I clean the filter on my shop vac?
Most filters can be tapped clean or washed with water. Always let the filter dry completely before reusing it for dry pickup. Check your model's manual for specific instructions.
What does the blower function do?
The blower function attaches the hose to the exhaust port, turning the vac into a powerful leaf blower for clearing debris from your garage, driveway, or workshop floor.
Can I use a shop vac for fine dust like plaster?
Yes, but you need a fine dust filter or a filter bag. Standard filters may clog quickly with very fine particles. Some models offer specific dust bags for this purpose.
How long is the hose on a typical shop vac under £100?
Most models in this price range come with a hose between 1.8m and 2.5m. The Bosch GAS 12-25 offers a slightly longer 2.5m hose for better reach.
Is a stainless steel drum better than a plastic one?
Stainless steel is more durable and rust-resistant, making it better for frequent wet pickup. Plastic drums are lighter and cheaper but can crack or stain over time.
What accessories come with a standard shop vac?
A standard kit usually includes a crevice tool, a floor nozzle, a wet pickup nozzle, and a dusting brush. Some models also include a cartridge filter and a foam filter for wet use.
Can I use a shop vac to unblock a drain?
Some shop vacs can be used for drain cleaning if they have a wet pickup function and the correct attachments. You must ensure the vac can handle the volume of water and debris.
