The benefit of cleaning involves a certain expenditure which increases directly proportional to cleaning intensity. Cleaning costs themselves are made up of about ~ 60% labour, ~5% administration, ~10% materials (detergence and care products, consumables) and about 25% for buying and maintaining the cleaning equipment.
However, disc brushes scrub a given floor surface area for longer than two roller brushes, assuming the same travel speed. They have, a shorter contact time, but this is more than compensated for by the higher number of bristles in contact and a higher rotation speed which creates a higher kinetic energy. Nonetheless, the contact time of disc brushes is not always identical: Owing to the circular scrubbing pattern, the edges are treated only briefly while the areas in the middle of the disc are treated for much longer.
Another advantage of roller brushes is the fact that they do not slew washing solution sideways. This means that their recovery efficiency is better and less water is lost in the recycling
mode. Furthermore, thanks to their high speed, they can also be used for polishing and crystallising.
Roller brush systems are particularly suitable for cleaning problem floors, such as non-slip tiles, studded rubber and other structured floor coverings, because they are better at getting into recesses than disc brushes. Advanced machines have nowadays the possibility to offer multiple speed settings so the machine can be tuned much more precisely to suit different cleaning challenges. In addition, roller brush systems normally include a sweeper function which means in that no pre-sweeping is required if only small dirt particles are littering the floor.
For both brush systems, different brush types are available as well as pads. From soft for granite tile floors to very hard brushes for stubborn sticky dirt, the right choice is important to get the best results. For pads, there is also wide choice available. During the demonstration of the machine, the suppliers should bring different sets to test and come up with the right solution for your cleaning challenge.
Another feature which can reduce the cost of the machine operation considerably over the usage period is to select a machine which has a detergent dosing system. The detergent is not poured in the fresh water tank but added from a separate tank to the fresh water flow at the brush and can be switched on/off or the detergent concentration regulated according to the soiled floor conditions. A smart operator can save 1000s of rupees. More advanced machines have even a smart dosing system which can be programmed by the supervisor so the operator can’t make mistakes.
So it is now up to you to make the right decision for the selection of the right machine seize for the area to be cleaned. It is not the original purchase price which should determine the decision but the kind of dirt to be removed, the frequency of cleaning and the cost per sqm which will give the least cost over a period of three or five years. The trained sales person of your machine supplier should be able to show you the calculation for the right machine with the perfect configuration.
