Air cleaning guns

The air cleaning gun loosens the dirt, the vacuum takes it away

What is an air cleaning gun? A compressed-air tool that swirls air, feeds in cleaner depending on the design, and loosens dust, sand and hair from gaps, carpet and floor mats. It doesn't suck anything up and needs a compressor with enough free air delivery.

Air cleaning guns are compressed-air tools for the interior, in which a thin tube spins inside the cone and sets the air jet into a fast rotation. As a tornado cleaner, the air cleaning gun works dry as a pure air vortex or with cleaner from the cup. Tornador is a brand name that has come to stand for the whole design. It loosens dirt from spots neither brush nor vacuum nozzle can reach.

• Air volume and working pressure have to match. Manufacturer examples are around 120 litres per minute for the STAHLWERK RP-90 ST and around 270 litres per minute for the Tornador Black Z-020RS. For the Black, Tornador calls for at least 10 per cent reserve above the tool's consumption. Compare free air delivery at the working pressure you need.
• The cup is what feeds in liquid. A suction-cup gun puts cleaner on the surface as well as air. Separately from that, the nozzle design decides how the air jet comes out. When AUTO ZEITUNG presented four cleaning guns, it looked at handling, how finely you can meter the cleaner, leak-tightness and a tank of at least one litre.
• Air can swirl without a cup, too. For the 9040T-1 turbo blow gun, HAZET quotes 80 litres of air per minute. According to the manufacturer, its swirl nozzle is designed for, among other things, upholstery and floor mats with pet hair. So dry cleaning doesn't necessarily need a liquid cup.

Detailing1's tip from the shop: With the gun free of liquid residue and the liquid feed switched off, test it in air mode against a light-coloured microfibre towel. If you see droplets or an oily film, check the tool and the air supply before using it on upholstery. The towel test doesn't prove where residues come from. For the Tornador Black, the manual calls for clean, dry air and a pressure regulator set to no more than 6.5 bar. For other models, follow their manual.

A cleaning gun swirls air and cleaner in the cone

A cleaning gun with a suction cup combines a spinning air jet with cleaner you can switch on; dry tools with a swirl nozzle, on the other hand, can loosen dirt from upholstery and floor mats without a liquid cup.

The design with liquid feed described here is called a suction-cup gun. That means the airflow draws the liquid out of the cup, rather than a pump pushing it. A thin hose or tube rotates in the cone, as SONAX describes it in its product information and Tornador in its manual. For you, that means the cleaner hits the fibres as a fine, spinning mist, not as a gush.

The suction-cup gun has two operating modes. Dry, described in the manual as air mode, the vortex blows dust out of air vents, seat rails and gaps. With cleaner in the cup, it lifts stains and grime film from floor mats, carpet and boot trim. Which mode you choose depends on whether the surface is allowed to get wet.

In April 2026, AUTO ZEITUNG presented four models, without a ranking or scores, and clearly named the weakness of the whole category: it doesn't suck anything up. Loosened dirt then has to be picked up with a towel or vacuum. That's not a flaw of any single model; it's how these tools work.

In the detailing scene, the cleaning gun has its place in interior detailing. Channels such as AUTOLACKAFFEN dedicate whole videos to interior cleaning with the Tornador gun, others put two models from the same maker side by side. In the forum posts we looked at, the question of the right compressor comes up too.

Interest in the category is growing quietly. According to Ahrefs, searches for the air cleaning gun are about 13 per cent above where they were five years ago. They peak every year in spring, just when road salt and winter grime need to come out of the footwells.

Cup and nozzle do different jobs

A liquid cup tells you nothing about whether the nozzle swirls the air: simple blow guns, dry tools with a swirl nozzle and suction-cup guns differ in their design.

A simple blow gun points an air jet at the surface. Alongside those, there are dry models with a swirl nozzle such as the HAZET 9040T-1, and suction-cup guns that also feed in liquid. So check the nozzle, operating modes and approved surfaces separately. The DGUV names lowering the pressure to 3 bar as a noise-reduction measure when blowing off; that's not an operating requirement for every cleaning gun.

Under search terms such as tornado cleaner with extraction, you'll also find designs meant to carry loosened dirt away through a connection. We haven't found reliable measurements for these. So we're leaving it at this classification. With tools without their own extraction, you need to plan for picking up the dirt afterwards with a vacuum or towel.

Water and exterior washing are a different job. The pressure washer works on paint and wheels with water pressure. The spray extraction vacuum sprays cleaner in and sucks it straight back out. To dry large surfaces, use a blower dryer.

One limit applies to all compressed-air tools. You don't blow off sanding dust from paint or filler. The DGUV information for vehicle paint shops says explicitly: don't blow it off with compressed air; pick the dust up with an industrial vacuum. The air jet would only spread it around the room.

The compressor decides, not the gun

A compressor that's too small makes the vortex collapse after a short time, because the tank empties faster than the motor can refill it. That's why free air delivery in litres per minute is what counts.

Free air delivery describes how much compressed air the compressor puts out at a given pressure. Hoses and fittings can further limit the supply at the tool. Sometimes only the higher intake capacity is printed on the box, which the unit only takes in theoretically. For you, that means comparing free air delivery at the required working pressure with the gun's air demand, not the intake capacity. Otherwise you buy a unit that's enough on paper and runs out of puff in the footwell.

A retailer example shows how far apart the two figures can be: for the Tornador Black, one retailer specifies at least 320 litres per minute of compressor intake capacity, around 50 litres per minute more than the gun's consumption according to Tornador. According to the manufacturer, it reaches full performance from 4.5 bar. So more bar won't help as long as the air volume is lacking.

The tank buffers peak demand so the motor doesn't keep cutting in. BenBow's manufacturer figure is a 50-litre tank as the minimum and 100 litres for professional work. A cordless compressor without a tank won't deliver continuous air for a cleaning gun. It inflates tyres; it won't cut it for the footwell.

Between the tank and the gun goes an air service unit with filter, water separator and pressure regulator. The water separator catches the condensation that forms during compression and collects in the hose. The water separator reduces how much condensation gets in from the compressed-air supply. Which compressor suits which job is covered under Compressors.

If you already own a compressor, look for the effective free air delivery on the rating plate or in the data sheet and set it against the gun's air demand plus reserve. If the delivery is lower, the gun only works in short bursts until the tank has refilled. That's exactly what users on autopflegeforum describe, whose small compressor had to recharge after a short time.

After the swirling, the loosened dirt has to be picked up

Vacuuming first cuts down on loose dirt the gun could spread around; once it's loosened, you pick it up with a vacuum or a microfibre towel, depending on the surface.

Step one: vacuum the interior dry, mats out, coarse dirt gone. A wet and dry vacuum from the vacuum cleaners also pulls the sand out of the felt. Step two, using the Tornador Black as an example: disconnect the air supply and make sure the system is depressurised before you unscrew the cup. Only fill in the approved cleaner immediately before use. Our guide Auto-Innenraum reinigen in der richtigen Reihenfolge explains the full interior sequence.

Step three, using the Tornador Black as an example: guide the nozzle slowly in circles at a distance of 1 to 3 centimetres and an angle of around 45 degrees. For other tools, their manuals and material approvals apply. Work in sections so the loosened dirt doesn't dry back on. Floor mats, carpet, boot, gaps and air vents are the spots where forum users describe the gun earning its keep.

Step four: pick up the loosened dirt straight away, with the wet and dry vacuum or a microfibre towel such as the GYEON Q²M InteriorWipe EVO "Edgeless" with its long-pile and short-pile sides. That way you reduce the risk of loosened dirt drying back on.

With sand and pet hair in the felt, the order pays off especially well. A user on the motor-talk forum describes sand being much easier to vacuum up after stirring it up with the gun than before. The second vacuum pass then gets what the first one couldn't reach.

Step five, following the Black manual: clean the cone in air mode in a bucket of clean water. Hoses and intake filter get a separate flush: disconnect the air supply, make sure the system is depressurised, empty and clean the cup, then fill it with clean water. Only reconnect once it's screwed back together. With the trigger lever vertical, run water through for about 20 seconds. To finish, disconnect the air supply again.

The first time, expect spray mist and moisture hanging in the interior. That's part of it, not a mistake. Pick up the moisture and let the surface dry. Users on autopflegeforum describe a cleaner smell after a round that was too wet; blowing out again or wet-vacuuming is no substitute for checking the remaining moisture.

The SONAX PROFILINE PowerAirClean is a suction-cup gun

If you don't check the design before buying, you might end up with a plain air jet when you wanted a vortex with cleaner. The SONAX PROFILINE PowerAirClean compressed-air gun belongs to this design.

According to SONAX's product information, the PowerAirClean works on the suction-cup principle with a rotating tube. It runs dry or with interior cleaner in the cup and is designed for cleaning vehicle interiors. That puts it among the cleaning guns with a cup, not the plain blow guns.

We're deliberately not quoting a reliable air demand for this tool. The figures doing the rounds in retail contradict each other considerably, and we haven't found an official SONAX data sheet with a delivery figure. The manufacturer examples above only give you a rough guide. To size the compressor properly, you need a confirmed air demand and working pressure for the PowerAirClean; figures from other models don't replace it.

According to the product text, the gun connects to a compressor, so a compressor is a must. Check the coupling, pressure regulator and water separator on your setup beforehand. When choosing a gun, it's also worth looking at spare parts. A user on the motor-talk forum names spare parts availability as the reason to stick with a branded tool.

For the spots where compressed air has no business, brush and towel are ready. You clean dashboards, displays and switches dry with the SONAX PROFILINE PinselSet and pick up the dust with a microfibre towel. You'll find more shapes under Brushes.

Without a suitable compressor, brushes and a vacuum are the better choice

If you buy a cleaning gun without a suitable compressor, you own a tool you can't run properly. So the decision starts with the compressor, not the gun.

If you don't have a compressor with enough free air delivery, brushes, a microfibre towel and a decent vacuum are plenty for normal vacuuming. If you have the compressor and lots of carpet, gaps and pet hair in the felt, the gun is worth it. If your upholstery regularly gets dirty deep down, reach for spray extraction instead of the gun.

It's exactly with upholstery that forums raise the question of whether compressed air works the dirt in deeper. After an upholstery session that went wrong, a user on autopflegeforum describes leftover dirt and a whitish haze from the cleaner.

Check the limits on the specific tool. According to its manual, the Tornador Black isn't insulated against electrical voltage; electronics and seat belts are ruled out for it. For other tools, you need the relevant tool and material approval. On airbag covers, TÜV SÜD warns that cleaners can attack the material. Treat the headliner only sparingly so it doesn't get soaked. The Black manual prohibits acidic, alkaline or highly flammable cleaners. For SONAX, its own tool and cleaner approvals apply.

Safety means safety glasses, hearing protection and respiratory protection against the spray mist, for bystanders too, as Tornador writes in the Black manual. Under DGUV rules, you never point the nozzle at your body and never blow off clothing. In the engine bay, on wheels and on the underbody, users report that the gun is unwieldy and doesn't do much.

In the end, it's a simple sum: the gun doesn't suck anything up. Whatever it loosens from gaps and felt has to be picked up afterwards with a vacuum or microfibre towel. You'll find all the tools in this chain under Cleaning equipment. Plan how you'll pick it up before you loosen it: only once the dirt is in the vacuum or the towel is it out of the interior.
