If rotaries are arguably more versatile and productive, why are scrubber dryers often indispensable?
The answer’s largely cylindrical, explains Gordon McVean, international sales and marketing director
at Truvox International.
There are more ways than one to clean a Floor, and still produce consistently satisfactory Results. Rotaries and scrubber dryers both do it, day in, day out, which is why buyers sometimes struggle when choosing between them.
Often it’s not a matter of right or wrong, but what’s better, depending on the type and mix of floors, their usage, and the comparative advantages of the brush and disc technology used by scrubber dryers and rotaries respectively.
As a manufacturer producing both machine types, including variants on the two themes, we have an even-handed perspective on the cylindrical brush versus disc cleaning debate. Firstly, a quick summary of why we’re founder members of the rotary fan club.
Rotaries are one of the most common cleaning machines in use worldwide, and for good reasons. They can undertake a wide variety of cleaning tasks. Contract cleaners and facilities managers appreciate how cost-effective they can be.
And improvements in recent years have made them even easier to operate.
Discs, whether driven by a belt or directly, can achieve very high speeds for burnishing, but the 200-400rpm range is suited to cleaning and maintenance, when large swathes of hard flooring can be tackled in a comparatively short time. Productivity rates range from more than 400m2/hour to 560m2/hour.
Depending on the speed and pad or brush attached, a rotary can glide through diverse tasks, from spray cleaning and scrubbing to polishing and bonnet mopping carpets.
This versatility is one of the main drivers of their popularity. A strong claim to the versatility title can be made on behalf of the scrubber dryer too.
No, this type of machine cannot buff and polish hard floors like a rotary fitted with the appropriate pad or brush. But a machine like the Multiwash can wash, mop, scrub, and dry in one pass.
The machine is compact, with a 34cm brush width. Its low height and long reach makes it ideal for cleaning under desks and furniture. It turns in a highly respectable productivity of at least 350m2/hour.
Impressive though that is, the machine goes further. The Multiwash turns in the same consistently high cleaning results across such a range of surfaces, it’s the all-terrain machine of floor cleaning. Its territory ranges from laminates, vinyl tiles, and linoleum to concrete, marble, stone, and slate.
This wide range also includes some surfaces that are problematical for other cleaning machines, such as safety floors and those with rubber studs. Entrance matting and low-pile carpets too are well within the cleaning capabilities of the Multiwash, which can also take elevator and travelator cleaning in its stride, when equipped with a specialist brush.
How is this possible? It’s largely down to cylindrical brush technology. This provides effective cleaning of hard floors by deep scrubbing, using minimal moisture, to leave floors thoroughly clean.
A cylindrical scrubber dryer pumps cleaning solution onto the hard floor, scrubs the floor using counter-rotating brushes and then picks up the cleaning solution – either through the rotary action of the Multiwash or with the in-built vacuum and squeegee blades of the Solaris – so the floor is safe to walk on in minutes.
The Solaris can easily clean hard floors at a rate of 470m2/hour – more than three times the productivity of traditional mopping, with far superior results.
It has a 40cm cleaning width. Most scrubber dryers that use cylindrical cleaning will also be very quiet in operation, making the machines ideal for daytime cleaning when in use around customers, patients and staff at work.
