The long standing question of what method of mechanical cleaning system is best for scrubbing floors remains as unanswered today as it has always been.
So what are the key differences between disc brush and cylinder brush methods? And which one is THE BEST?
Rotary floor scrubbers, utilising the rotating disc brush system, are ideal for wet stripping, scrubbing and buffing floors.
Scrubber driers using disc brushes work well on smooth surfaces and large walk behind and ride-on machines will save time in open areas whereas smaller compact machines such as the Comac Vispa 35B are better suited to more congested areas such as restaurants, school classrooms etc, where they effectively wash and dry floors and can even be used to strip wax from the floor.
Disc brush machines offer easy to change, variably aggressive, pads or brushes.
These features make disc scrubber driers ideal for retail applications where pads are not only inexpensive, but offer a great deal of surface contact for scuff mark control and floor shine. For industrial applications, disc brushes often make sense because they deliver greater down pressure than cylindrical brooms, and heavily soiled floors benefit from heavy down pressure.
Cylindrical brush machines are great for uneven surfaces and floors with grout lines.
Cylinder brush machines such as the Multiwash and Nilfisk CA340 allow you to wet the floor, scrub and dry in a single pass and are particularly effective on non-slip safety floors and also for cleaning the grouting between tiles.
Cylindrical brush scrubber driers, such as the Fimap Genie BS, will (wet) sweep small amounts of solid debris into a removable tray whilst also washing, and drying, the floor.
In this event it is possible to eliminate the manual pre-sweeping of floors for greater productivity with less potential blockages in the squeegee section of the scrubber drier. In addition, there is often no need for a separate sweeper when a cylindrical brush scrubber drier will do the job.
Cylindrical scrub brushes keep less bristle surface in contact with the floor than disc brushes but they usually turn their brushes up to three times the rotation speed of a disc brush. This will often offset the greater surface area advantage that disc brush scrub decks offer.
Which is better? Both versions have a good rating on cleaning performance and both will clean your floor!
Disc scrub brushes have the advantage of lower initial cost and simplicity of maintenance. A disc brush will last longer and a replacement brush usually will cost less than a cylindrical brush. Cylindrical brush decks (as an option) will typically increase scrubber drier cost by £500 to £1000.
Cylindrical scrub decks eliminate the need to pre sweep your floor and may save the expense of true combination scrubber/ sweeper machines or separate dry sweepers.
It is fair to conclude that both systems have advantages over each other and both will deliver good cleaning performance, so ultimately it is the type of floor surface, the level and nature of soiling, and of course the budget that will influence the final decision.
