What is a scruber dryer & how it works Floor cleaning takes up about 54% of overall cleaning time. On the other hand the floor represents important aspects of the comfort of an environment: • The aesthetic aspect linked to cleaning and to its finishing • The safety aspect linked to a floor slipperiness • The hygiene aspect linked to cleaning and sanitation These observations gave rise to the need to mechanise floor- cleaning, with the aims of • Reducing floor-cleaning times • Making the floor immediately usable • Assuring constant cleaning results
The automatic scrubbing machines were designed to satisfy these aims. Inone single operation, theyWash, dry and sanitise the floor, leaving the surface completely dry.The machine consists of:• A washing unit with one, to or up to four disc or roller brushes, activated byelectric motors using water and detergent to remove the dirt.• A collection and suction system for floor dirty water (squeegee)• Water and detergent deposits (also called solution) and recovery deposits(dirty water)• A control and driving system• The machines can be powered with a battery (or batteries), cable-powered(mains) or, for the largest models, with petrol or diesel motors• The operator can use the machines walking (walk-behind scrubbingmachines) or sitting on them (ride-on scrubbing machines).
Why should I use a scrubbing machine for cleaning areas of limited size?There are many reasons, but well concentrate on the mainones (those put forward by the users themselves). The mainreason is that when you use a scrubbing machine with theright detergent, the floor gets an important sanitationprocess that cannot be compared with the manual cleaningsystems (mop + bucket) usually used on environments withsmall surfaces (up to about 1,000 sqm). Furthermore,cleaning operations take just half the time and require noeffort at all from the operator. All things considered, thereare good economic savings.
Obviously not. While offering benefits of a professionalnature, their use is very easy thanks to the attentionplaced in making their tasks as easy as possible for bothbattery and cable-powered models. Training is completelyunnecessary; just follow the instructions in the manualand youre ready to work.Thanks to years of experience, the current models havesimplified command systems while assuring maximumproduct functionality. On larger machines, the use ofelectronics means the command systems have a singlebutton for machine operation, and specific washingprograms can be pre-set for the desired application.Furthermore, the special attention to the ergonomic formof the instrument panels and commands allows you toimmediately recognise the individual functions, solearning times for the operator are minimised.
Do scrubbing machines have avery high water and detergent consumption?
The automation of floor-cleaning involves:- A reduction in working times and the immediate floor usage -Improving the hygienic standard of the surface and the maintenanceover the time - Consumption reduction associated with washingoperationsIndeedWater: cleaning by scrubbing machine optimises water consumption(and consequently detergent).As a comparison, we can wash and sanitise one sq.m. of floor using 0.05litres of solution, against the 0.5 litres needed with the manualsystem, while assuring highly improved hygiene results.Detergent: a reduction in water consumption means a reduction indetergent consumption too. Referring again tothe previous example, with 5cc of concentrated detergent we can wash10 s.q.m.
Does it need a lot of maintenance? The scrubbing machine washes and picks up the dirt, this consideration justifies the need for maintenance related to its use. The technology and technical solutions have made possible the minimisation of the necessary operations. After using the machine it is necessary to drain the dirty water and rinse out the recovery tank, clean the squeegee rubbers and if the machine is battery-powered, recharge the batteries. The filters must be cleaned regularly, with an authorised technician carrying out a check occasionally, or once a year
Is the machine difficult to use?• It is really easy to use the sweeping machine, whether it is a walk-behind, or ride-on model. Naturally, larger machines have more specific commands, but in all cases these are simple, intuitive machines requiring the minimum learning time.
Which version is better - the one withan internal combustion motor or the battery-powered one?• They answer different needs. The internal combustion motor (using petrol or diesel) is suitable for outdoor use, while the battery version cannot work outdoors, but is definitely more suitable for indoor operations. The latest models.Our machines are designed to assure, also for the battery versions, usage times comparable with those obtained from versions with an internal combustion motor. These versions can therefore be used for large indoor surfaces too, without the resorting to other solutions.
Can any type of waste be picked up?• Everything can be picked up, except rope, strings, and metal or plastic supports: these can damage the central brush. However the dirt collected must not be fixed to the ground, and the sizes of individual elements should not exceed those provided for their passage to the collection drawer. So large machines can remove bigger, heavier dirt than small ones.
Is the waste collected at the front or back?• The sweeping machines have a waste hopper; it can be fitted at either the front or the back. Both loading systems have advantages and disadvantages of. Our machine uses rear loading for its smaller models, giving priority to the collection and loading capacity of small, lightweight debris. On larger models however, front loading allows the collection of larger, heavier waste (for which these models are more suitable). The focus is therefore on the functional aspect of the individual models, without damaging other aspects such as visibility, accessibility, comfort, effective container volume, and type of filters.
Can I work if the floor is damp?• Yes, if we are talking about wet surface or limited water patches. Naturally, in these conditions there is no dust problem so you can work without suction. This also means the filter is protected against the dampness, that would damage its surface and make it impossible to clean, forcing you to then replace it.
Does it need frequent maintenance?• The sweeping machine is a simple device requiring no continuous maintenance. Like all cleaning machines, just a minimum amount of maintenance is necessary after use: emptying of the waste container, cleaning of the filter, visual check of the brushes. With the motorised versions, you should always follow the manufacturers indications (oil, filters and so on), although these are reduced to a minimum now as well.• It is advisable to have a check carried out by an authorised technician at least once a year, or after 250 work hours. It is important not to work in environments where there are rope, strings, straps or nylon packaging of a size that could get caught up in the central brush and prevent it from working.
What do the suction vacuum and air flow rate values mean?• These are two typical vacuum cleaner characteristics that we can sum up in this way:• Suction vacuum is the capacity to lift the material to be removed. The greater the value, the greater the lifting capacity. The air flow rate is the capacity to convey the lifted material and, when there is a lot of dust, to keep it suspended in the tubes. The correct combination of the two values therefore allows the material to be lifted and, at the same time, conveyed towards a collection container.
Can I remove dust and liquids at the same time?• Some models are designed to remove solids and liquids simultaneously. This is done by directing the air flow (which conveys the solids and liquids) not directly onto the filter but onto a dynamic (cyclone) separator. In this way, the heaviest material is collected at the bottom of the container (and liquids can be separated from solids via grilles), while the air with the lighter particles is filtered and sent back into the environment.• When removing liquids with a vacuum cleaner, or for liquids with no dynamic separation, the paper/fabric filter must be removed.
How do I choose the type of filter?• The models are equipped with class L filters.• For increased filtering needs (a greater capacity to hold back dust that passes through the filter), there are class M filters. For specific suction operations such as fine dust or bacterial charges, class H (Hepa) filters are available. These filters cannot be used by themselves - they must be preceded by filters of a lower category (L or H). Additional filters (nylon, TNT or disposable paper bags) are also available for specific requirements.
When removing large quantities of dust, do I have to interrupt the job often or can I work continuously?• A special model - three-phase, of course - has been developed for this precise application. It can work continuously because the filter cleaning operation is carried out via air flow reversal and the mechanical action of a hammer activated by the air flow.• For less extreme applications, some models (SEA) have an automatic electric filter shaker.
Single disc machines The single disc machines are ideal fordeep-down and maintenance cleaning,where the surface needs to be treated or protected.
Whats the difference between asingle disc machine and a scrubbing machine?
• The single disc machine is technically more simple. It was created before the scrubbing machine, with the aim of mechanising cleaning operations - especially the washing and treatment of very different types of flooring (marble, terraces, wood, terracotta, klinker, linoleum, etc.). The cleaning operation therefore requires two alternate phases (washing - drying), mechanising a task that would otherwise be performed manually by two operators, taking more time. The scrubbing machine is the evolution of the single disc machine, equipped with a system for collecting the water/detergent solution and dirt removed from the floor. So the single disc machine is still the best for deep-down cleaning operations and special treatment, but the scrubbing machine is more suitable for maintenance cleaning, where adherent dirt needs to be removed without intervening on the surface and the floor must be ready for use again as quickly as possible.
Can I wash and polish with a single machine?• There are models that can work at two different speeds (usually 150-300 rpm), so they can be used for both washing and polishing. Please remember that these are compromise solutions however; they cant be compared with the use of two specific machines (a classic 150-160 and a high speed machine of 400 rpm), and they are only suitable for surfaces of limited size
Are they easy to use?• Theyre professional machines. This means that, to use them, some training is needed with regards both maneuvering and - especially - treatments (using the specific products and pads). Machine maneuvering varies for high and low speeds. Low speeds require an alternated right-left movement and, for specific needs, you can work in a limited area; high speeds need continuous, straight line movements.
