Frequently Asked Questions - Twin TT Aquafilter THOMAS

How does the water filtration system work on the Thomas Twin TT Aquafilter?

The vacuum draws air through a water tank, where dust and allergens are trapped in the water. The clean air then passes through a HEPA filter for final filtration.

How often should I change the water and clean the tank?

After every use, empty the dirty water, rinse the tank with clean water, and allow it to dry. The filter should be replaced annually or when dirty.

Can I use the Twin TT Aquafilter on carpets?

Yes, it is suitable for low-pile carpets and hard floors. For high-pile carpets, use the turbo brush accessory if included.

What does the Twin TT stand for?

The 'Twin' refers to dual motors: one for suction and one for the water turbine, while 'TT' likely stands for Turbo Twin or similar technology.

How do I maintain the suction power?

Regularly clean the water tank and ensure no blockages in the hose or brush. Replace the HEPA filter as recommended to maintain airflow.

Is the vacuum safe for allergy sufferers?

Yes, the water filtration traps 99.9% of allergens like dust mites and pollen, making it ideal for allergy prevention.

What should I do if the vacuum overheats?

The vacuum has an overheat protection feature that will automatically shut it off. Let it cool for at least 30 minutes before restarting.

Can I vacuum liquids with this model?

The Twin TT Aquafilter is designed for dry vacuuming only. Do not use it to pick up liquids as it may damage the motor.

Where can I find replacement parts?

Replacement parts such as filters, hoses, and brushes are available through Thomas service centers or authorized online retailers.

How do I store the vacuum?

Empty and dry the water tank, wrap the cord around the cord hooks, and store in a dry place. Keep the vacuum upright to prevent water leakage.

Dust vacuuming

Information for use

• Do not use the TWIN tt AQUAFILTER for dry vacuuming if the AQUAFILTER system has not been appropriately fitted according to the operating instructions. This could cause damage to the appliance.
• Do not suck up any liquids when dry vacuuming.
• Do not suck up any large quantity of fine dust, for example, chocolate powder, flour, etc.

To make the AQUA filter ready for use

Your TWIN # AQUAFILTER is set ready for dry vacuuming at the works.

Open appliance cover by lifting up the cover catch.

Draw out the AQUA filter from the dirty water tank by means of the grip. Fill up the dirty water tank with 1 litre of clean water. Insert the complete AQUA filter up to the stop behind the two guide ribs of the dirty water tank.

At the same time make sure that the wet filter is fitted and the circumventing AQUA filter seal is tight up against the inside of the dirty water tank.

Connect up suction hose and fit telescopic suction tube. Connect the required accessory.

To achieve optimal filtration we recommend rinsing out the AQUA filter quickly with clear water after approx. 40-60 minutes continuous operation or when a large number of drops of water can be seen on the underside of the cover. You should also change the water in the dirty water tank.

Should crevice nozzle or upholstery nozzle be fitted to the tube bend, use the nozzle adapter which can be fastened to the shut-off valve (24).

Insert nozzle adapter in either the crevice nozzle or upholstery nozzle before fastening the shut-off valve to the adapter.

The AQUAFILTER system is to be emptied and cleaned every time the appliance is used for hygienic reasons. Dirty water and moist parts propagate the growth of bacteria and fungi (see cleaning and maintenance instructions).

Wash suction cleaning/sucking up liquids

Information for use

• Caution! Petrol, thinners, heating oil, etc., can develop explosive vapour and mixtures when mixed with the intake air.
• Acetone, acids and solvents can attack the materials used to produce the appliance. Clean and dirty water can be sucked up without any hesitation.
• Clean and dry the dirty water tank and all the used parts after sucking up liquids.
• Never suck up liquids without the dirty water tank.
• Your THOMAS TWIN it AQUAFILTER is not suitable for sucking up larger quantities of liquid from containers or basins.
• Caution! Never operate the pump without liquid.
• Empty and clean the appliance every time it is used for wet cleaning. Dirty water and moist parts propagate the growth of bacteria and fungi (see cleaning and maintenance instructions).

Only use original products and parts to ensure perfect cleaning results.

You can get further supplies of the original THOMAS concentrated cleaning agent from your specialist dealer or the THOMAS Works Customer Service Department.

Before cleaning carpets

- Make sure that everything you want to wet clean is also suitable for wet cleaning. Do not wet clean your sensitive, hand-woven or non-fast dyed carpets, for example.

To check this apply a little cleaning agent solution to a soft cloth and rub this on the carpet at a not too apparent point. Should no traces of dye appear on the cloth it can be assumed that the dye is colourfast.

The carpet must not be wet cleaned should this not be the case.

Should you have any doubts please consult your specialist carpet dealer.

Should the carpet have been shampooed at an earlier point in time it may well be that stronger foaming will occur in the dirty water tank when using the THOMAS TWIN it AQUAFILTER for the first time. Add half a cup of vinegar to the dirty water tank to prevent any further development of foam.

Immediately switch off the appliance and empty the dirty water tank should foam escape from the air outlet.

When using the THOMAS cleaning concentrate for thorough cleaning any increased foaming is excluded because this concentrated cleaning agent is provided with a special anti-foaming agent.

You should not walk over your cleaned carpet as long as it is wet.

The room should be well ventilated both while cleaning and afterwards to ensure quick drying.

Carpet cleaning

Put the 2-piece anti-swash insert together.

Draw out the AQUA filter from the dirty water tank by the grip and fit the anti-swash insert.

Remove HEPA filter from the appliance.

Insert the anti-swash insert and dirty water tank in the appliance. Make sure that both the wet filter (13a) and the motor protection filter (15) are fitted.

Remove the fresh water tank for filling (draw tank straight upwards and out of the cleaner or fill up directly in the appliance. In this case you have to lift up fresh water tank cover.

When filling make sure that no impurities get into the fresh water tank to prevent the dosing valve from not functioning properly.

Fill up with cleaning concentrate and water to the grip lug (max. 2.4 litres).

We recommend THOMAS ProTex original concentrated cleaning agent for cleaning carpets.

See label on the cleaning concentrate bottle for application and dosage.

Use hand warm water (max. 30°C).

Connect up suction hose and fit telescopic suction tube.

Fit carpet spray nozzle (without hard floor adapter), connect up cleaning agent hose fast coupling to the shut-off valve and lock by turning. Then fasten the cleaning agent hose by means of the two tube clips on the suction tube.

Pull out the mains power supply plug and cable from the appliance and connect up.

Switch on the appliance and set for maximum suction power. Switch on pump. Control lamp comes on.

The spray extraction system

- The cleaning solution is sprayed deep into the carpet under pressure

- Dirt is detached and washed out fibre-deep

- Soiled water is extracted at maximum power and carpet pile restored to upright position.

All in one operation.

Detachment and washing out

Press the lever on the shut-off valve (24) until cleaning fluid escapes. Draw the nozzle straight over the carpet and press down the nozzle on the carpet at the same time. Release the valve lever at the end of a strip or when stopping work to stop spraying. When the sprayed liquid has been sucked up, lift the nozzle and begin at a new line with slight overlapping. In this way you can treat the entire area strip for strip.

i Should there still be traces of liquid remaining on the cleaned strips this liquid can be sucked up without having to spray again.

Make sure that the mechanical suction controller (25) is completely closed.

In the case of very stubborn dirt you can apply cleaning fluid when moving the carpet spraying nozzle forwards. The treatment can also be carried out by just putting the pump into operation.

Ensure that you do not spread too much liquid over the carpeting since this may cause waves or bumps in the carpet which, however, will disappear again after a longer drying period.

To avoid the liquid running back into the suction tube when stopping work hold the suction tube and hose upwards at an angle for a few seconds while the motor is still running. Turn off the appliance only after you have done this.

i Empty the dirty water tank after you have used up all the water and completely fill the cleansing agent tank from the fresh water tank to prevent the appliance being switched off automatically.

Should you not observe the above-mentioned instructions the float will automatically switch off the appliance as soon as the dirty water tank is full. (The motor will be clearly heard to be running at a higher speed.

Switch off appliance, disconnect the mains plug and empty the dirty water tank.

Hard floor cleaning

Push the hard floor adapter into the carpet spray nozzle.

By using this system you can clean and dry your hard floor coverings at one and the same time.

See carpet cleaning for procedure.

We recommend THOMAS ProFloor concentrated cleaning agent for hard floor cleaning.

Upholstery cleaning

Use the upholstery spray nozzle to clean upholstered furniture, car seats, etc. Push this nozzle on the handle together with the shut-off valve (24). Fasten the short spraying hose to the shut-off valve and nozzle.

When cleaning upholstery make sure that not too much liquid is applied because you will have to take a longer drying time into consideration depending on the sub-structure.

See carpet cleaning for procedure.

We recommend THOMAS ProTex concentrated cleaning agent for upholstery cleaning.

Window cleaning

Push the window nozzle adapter on the carpet spray nozzle. You can clean your windows and glass surfaces with this system and dry the surfaces at the same time.

See carpet cleaning for procedure.

To suck up liquids

You can suck up spilled, non-hazardous water-based liquids (for example water, coffee, etc.) with the THOMAS TWIN tt AQUAFILTER.

Select a suitable nozzle and fit it to the respective suction tube or handle.

Cleaning and maintenance

Only service and clean the appliance when it is switched off and the mains power plug has been connected.

After wash cleaning / sucking up liquid

iPlease use a moist soft cloth to clean the appliance housing. Do not use any aggressive cleaning agents or solvents.

Remove fresh water tank empty.

Empty dirty water tank.

Clean anti-swash insert, dirty water tank and wet filter using clear, possibly warm water.

Check motor protection filter for contamination and clean under flowing water and renew, if necessary.

Keep float (13b) in the dirty water tank clean and fully functional at all times. This float interrupts the suction operation when the dirty water tank is full.

Dry up spray water in suction chamber with soft cloth.

Remove contamination on the intake connector and on the inside of the housing cover.

i The housing cover can be taken off the appliance for easier cleaning.

To do this open the cover and swing it down vertically. Press the cover forwards until it slides out of the hinge. Afterwards swing the cover upwards and out of the way.

Insert in the housing cover vertically to fasten and close it. The cover automatically clips into the hinge.

Fill the fresh water tank with clear water to service the pump and valves and make the appliance ready for operation.

Put the spraying system into operation (operate the lever on the shut-off valve) over a wash basin, for example.

The appliance and accessory parts are to be thoroughly dried after being used for cleaning.

Press the shut-off valve lever to make the system completely pressureless.

After vacuuming

1. AQUA filter system

Open housing cover by lifting up the cover catch.

Remove dirty water tank.

Pull the AQUA filter (12) out of the dirty water tank by means of the grip and pour the dirty water away (for example in the toilet).

Remove foam filter (12a). To do this pull the AQUA filter frame slightly upwards and then fold it over to the side out of the way.

Now thoroughly rinse the AQUA filter, foam filter, wet filter and the dirty water tank with clear water. Do not use any cleaning agents.

It is essential to ensure that the parts are dry before being refitted.

The filter can be also removed for easier cleaning when dirt and fluff have blocked the suction filter (12b); refit the suction filter after cleaning.

Remove contamination and fluff on the suction connector.

2. HEPA filter

Your TWIN tt AQUAFILTER is provided with a high quality HEPA filter (14), which can be cleaned several times depending on your needs and the type of dust found in your home.

Clean your appliance when the suction power decreases and as when needed (at the latest every six months). Proceed as follows:

Remove the HEPA filter from the appliance and knock out the dirt on a firm underlay.

If the filter is strongly contaminated it can also be rinsed out with clear water (without cleaning agent) and be subsequently cleaned by knocking out the dirt.

Do not use any brushes for cleaning. Always allow the filter to dry out thoroughly before fitting it back into the appliance again.

Do not damage the filter fins when cleaning the HEPA filter.

The filter is to be replaced by a new filter should the suction power of the appliance not be improved to a considerably extent after cleaning the HEPA filter.

3. MKA microfilter

The MKA microfilter (19) is to be replaced every six months.

To do this press down the two plastic lugs on the blow-out cover and fold it back.
