Soft intermediate brush (Gold/White):
Best used for 100%, 80/20 and 50/50 wool carpets. Excellent for cleaning rugs such as Orientals and Persians. 

Standard brush (White):
The most versatile of all the brushes, effective on both residential and commercial carpets. It can be used on virtually all carpets except for delicate wool and wool berber carpets and rugs. Especially effective on moderately soiled cut pile carpets.

Stiff intermediate brush (Black/White):
This brush has a combination of stiff and standard bristles so that it is effective in not only cleaning moderate to heavily soiled carpets but is also effective in lifting crushed carpet tiles. Great on both loop and cut pile carpets.

Stock code: E40-4-9002BK

The Envirodri system is one of the most efficient and environmentally responsible ways to clean all types of carpet without the use of water.

To be used in conjunction with Pro 40 Envirodri Microsponges, the Envirodri dry carpet cleaning machine is suitable for both spot and deep cleaning schedules and enables facilities to maintain their flooring without disruption to daily activities. 

The system cleans using 100% biodegradable, natural, soft, sponge-like particles which have been moistened with just the right amount of cleaning ingredients to dissolve and absorb dirt and grime from carpet fibres. The GEN4 machine effortlessly glides over carpets, agitating the microsponges into the fibres whilst also acting as a pile lifter - cleaning whilst simultaneously restoring previously flat, crushed carpet. After use, simply vacuum to reveal clean, odour-free and dry carpeting.

Dry carpet cleaning is one of the most efficient ways to clean all types of carpet without the use of water. The Envirodri Dry Carpet Cleaning system is simple, reliable, environmentally responsible and above all economical, where the products do the hard work for you, reducing labour, downtime and waste.

How The Dry Carpet Cleaning Machine Works

The Envirodri system uses a cleaning powder (Pro 40 Envirodri Microsponges), which is slightly moistened with just the right amount of detergent and wetting agents which is sprinkled over a carpet. The GEN4 CRB (counter-rotating brush) dry carpet cleaning machine is then used to agitate the granules deep into the carpet pile, which get straight to work to absorb dirt and deodorise the floor. Once complete, these granules are then vacuumed away leaving behind a dry, clean carpet, ready for immediate use.

Pro 40 Envirodri Microsponges
Pro 40 Envirodri Microsponges

Stock code: PRO40

Suitable for use on all carpet types, Pro 40 Microsponges is one of the most advanced dry carpet cleaning powders on the market today. 

Made from natural, soft, sponge-like cellulose fibres these microsponges have been moistened with just the right amount of cleaning ingredients to dissolve and remove dirt and grime from carpet fibres. 

Suitable for all types of carpet and both spot or deep cleaning, the microsponges should be used in conjunction with the Envirodri GEN 4 Dry Carpet Cleaning Machine or a carpet brush. 

Benefits of Using a Dry Carpet Cleaning Powder

No downtime

One of the main benefits of dry carpet cleaning is the rapid drying time – a significant factor for 24-hour businesses and facilities. Dry carpet cleaning is exactly that, it cleans carpets whilst keeping them dry. Businesses which operate 24 hours a day or that require a quick turn-around favour this method as carpets are cleaned and can then be put back into immediate use. Traditional wet cleaning can require anything up to 48 hours to fully dry – meaning sections of a building must be fenced off or closed down completely.

Along with this, as carpets can be used during and immediately after cleaning, carpet maintenance can take place at any time convenient to the business, whether this is during peak times, early morning or overnight.

No sticky residue or water marks

Wet carpet cleaning uses vast quantities of water. By using such a volume of water the operator risks causing water damage to furniture, fixtures and of course the carpet itself. As no water or heavy liquid detergents are applied with a dry carpet cleaning powder there is no risk of watermarks or sticky residue being left behind.

Shrinkage and expansion

Some types of carpet are at risk of shrinkage or expansion, which is caused by sudden dramatic changes to its temperature and moisture content. Dry carpet cleaning adds very little extra moisture to a carpet and is always room temperature so the risk of any type of shrinkage/expansion is zero.

Mildew or mould

When there is a lot of moisture and limited ventilation/poor drying conditions mould or mildew can become a problem. Not only can this be costly but can also pose as a health risk to customers and staff. There is no risk of mould or mildew when dry carpet cleaning. In fact, the Cleantec dry carpet cleaning system uses environmentally responsible products so indoor air quality is never compromised.

Suitable for all carpet types

Unlike wet methods, the Cleantec dry carpet cleaning powder is suitable for all carpet types. So whether you’re cleaning on raised office flooring, commercial carpet tiles, Persian rugs, sisal or wool you will always be able to carry out your carpet maintenance using this product. Our carpet cleaning products have also passed the rigorous independent tests of the Woolsafe board and carry the ‘suitable for use on wool’ as well as the 'suitable for use on synthetic fibres' endorsements. Something you are unlikely to see with other methods.

Our Pro 40 Envirodri Microsponges are also compatible with other counter rotating brush and low moisture extraction machines including the HOST Freestyle Carpet Cleaning Machine, the HOST Liberator Carpet Cleaning Machine and the HOST Reliant Dry Carpet Cleaning Machine. 

<h2">How to use PRO40 Envirodri Dry Carpet Cleaning Powder

Vacuum the carpet thoroughly. Most dry dirt is found at the base of the carpet and should be removed prior to commencing cleaning. Vacuuming also assists in opening the carpet pile allowing for deep cleaning. 

Working in small areas at a time apply the dry carpet cleaning microsponges directly to the carpet and brush in using the  Envirodri GEN4 Dry carpet cleaning machine or other dry extraction carpet cleaning machine. Leave for a few minutes to allow the compound to dissolve and absorb dirt and vacuum away. For treating heavily soiled areas use PRO40 Envirodri Microsponges in conjunction with PRO7  Biological Carpet and Upholstery Cleaner, PRO41 Envirodri Spot Remover and PRO43  Envirodri Pre-Cleaner.
