Adding the patented SMARTKIT system to Charis-ONE enables automatic chemical dosing, carpet pre-spray with a concentrated solution, and carpet rinsing.
The concentrated chemical is contained in a bottle, while the machine tank contains only clean water. When the use of chemical is required, the machine automatically uses it in the optimal concentration, either during extraction cleaning or carpet prespray.

Using the special hose and gun, carpet prespray can be carried out by spraying a concentrated solution of chemical, which is left to act for a few minutes before cleaning. The prolonged action of the chemical facilitates the removal of dirt from the fibers, enabling better cleaning results and speeding up subsequent cleaning operations.

During carpet extraction cleaning, the machine delivers a controlled concentration of product without requiring the operator to perform any dilution. This avoids incorrect concentrations and wastage of product.

With SMARTKIT, carpet rinsing can be carried out by simply turning a lever. The rinsing step is recommended to remove any sticky residue of chemical from the carpet fibers, which would otherwise cause rapid re-soiling after cleaning. By rinsing the carpet at the end of the cleaning process, it will slowly resoil as it did when it was new.

If the prespray is carried out completely over the entire surface, no additional chemical will need to be used in subsequent cleaning operations, but cleaning can be done usingonly clean water. In this way, cleaning and rinsing are carried out at the same time, saving time, detergent and water.

Cleaning companies, hotels, conference halls, restaurants, clubs, pubs, offices, banks, shops, cinemas, theatres, ferry boats, ships, airports, fitness centres, school, universities, shopping centres, places of worship, mosques and all places with middle-sized surfaces of carpet. 

1. Very quiet operation, which allows the machine to be used without discomfort to the operator and other people. The machine can also be used during normal work activities and in particularly noise-sensitive environments, such as hotels, offices, and banks.
2. The three-stage high-waterlift vacuum system enables unparalleled dirt removal and a very short drying time: carpet can be dried in 1 hour!
3. Powerful and reliable rotary brush motor for vigorous brushing action.
4. Ability to adjust the height of the rotating brush to suit the type of carpet and degree of dirt.
5. Replaceable brush easily and without turning the machine over.
6. By rotating a lever, it is possible to select deep cleaning or maintenance cleaning mode, increasing or decreasing the flow rate of water sprayed.
7. Special profile of the vacuum head for better drying.
8. All controls are placed at a comfortable height for the operator.
9. Water spray operable by simply turning the machine's guide knob.
10. "Quick-disconnect" spray nozzles, replaceable by hand without the use of tools. Nozzles can be cleaned easily. The entire nozzle holder manifold can be taken out of the machine without having to bend the machine to one side to disassemble the nozzles.
11. Possibility of attaching the instant water heater (HT1800) to the machine body to increase cleaning efficiency.
12. With the addition of the patented SMARTKIT system, automatic chemical dosing, carpet pre-spray and rinsing is possible.
13. Possibility to connect the machine with optional external hoses and accessories, such as a carpet cleaning wand or a hand tool for cleaning upholstered fabrics and hard-to-reach corner.

1. High density polyethylene tanks, very strong and made for lasting a long time.
2. Transparent unbreakable cover, which allows to see the dirty water while it is sucked.
3. Easy to reach hole for filling the tank with clean water.
4. Drainpipe for easily emptying the recovery tank.
