Scrubber Dryer Commonly Used Terminology Explained
Here are some additional explanations to complement the types of scrubber dryers previously described, detailing the terminology used by manufacturers and its importance in assisting you to make an informed decision.
Power Source - Mains Cable or Battery Operated
An important decision to make is whether to invest in mains cable or battery-operated machines, as each comes with its own set of advantages and disadvantages. Mains cable machines can be used anytime, as long as electrical sockets are available, allowing for extended operation. However, the downside is that the cable may become a nuisance in smaller spaces, presenting a trip hazard or the risk of damaging the cable, which could result in the machine malfunctioning and needing a replacement cable. With careful management, mains cables can be used safely without issues.
On the other hand, battery-operated machines are free from cable complications, making them a popular choice for adhering to health and safety guidelines. They allow operators to move freely wherever needed. The downside, however, is that battery-operated scrubber dryers are constrained by their battery capacity and runtime before requiring a recharge. Main cable scrubber dryers are generally more affordable than their battery counterparts. Neglecting battery maintenance can lead to battery failure, necessitating expensive replacements.
A relatively new innovation in the industry is interchangeable 'click-in & click-out' batteries, similar to those used in power tools. This system offers significant advantages; by purchasing extra batteries, you can charge one while using another to operate the machine. This theoretically allows for continuous cleaning without the need for mains cables. Additionally, the batteries can be charged in a safe dock rather than needing the scrubber dryer to be parked near an electrical outlet.
To make an informed decision, assess the areas where the scrubber dryer will be used. Look for any obstacles that cannot be moved and consider the number and proximity of electrical outlets, keeping in mind that mains cable scrubber dryers typically come with 15 to 20-meter cables. For battery-operated scrubber dryers, determine the size of the floor area to be cleaned and verify the runtime of the potential machine. Battery-powered scrubbers are gaining popularity, and advancements in battery technology now allow for longer usage periods without recharging.
Lithium batteries have become a standard feature or an upgrade option in scrubber dryer models. These batteries provide numerous advantages, including extended run times, reduced charging times, and enhanced battery life, along with increased battery cycles. Lithium batteries are lighter than lead-acid batteries, making scrubber dryers easier to maneuver. They require less maintenance, eliminating the need for regular water top-ups, which reduces the risk of damage. A key advantage of lithium batteries is their consistent power output, ensuring efficient performance during extended cleaning sessions, especially in larger facilities. They are also more environmentally friendly, with a longer lifespan and faster charging that minimises downtime and waste.
It's simply a matter of calculating the floor area and productivity rate to ensure you select a machine with sufficient battery life for your needs.
Scrubber Dryer Dimensions
The cleaning and scrubbing width, along with the squeegee blade suction unit's dimensions, indicate how effectively a scrubber dryer can clean a particular floor area. However, it's equally important to consider the actual physical dimensions of the scrubber dryer itself. Here are some key points to ponder:
- Does the machine need to fit through specific doorways and tight spaces?
- Where will the machine be kept and charged, if necessary? Additionally, is there enough space available for it?
- Will the machine need to be transported between different locations?
Scrubber Dryer Cleaning/Working/Scrubbing Width
The cleaning width is influenced by the size and positioning of the cleaning or scrubbing brush, cleaning pad holder, or cylindrical roller, which differs from the overall machine width. This information is important for estimating the time required to clean a floor. Additionally, the dimensions of the area being cleaned are significant, especially if there are narrow gaps or passageways that the machine must manoeuvre through. A commonly used cleaning width for single rotary scrubbing brushes on compact scrubber dryers is 15 inches or 400 mm, allowing easy navigation through doorways and tighter spaces. Larger walk-behind models can feature dual rotary or cylindrical brushes, Ride-on scrubber dryers come in configurations with one, two, or three rotary scrubbing brushes.
Scrubber Dryer Squeegee Width
The squeegee suction unit effectively gathers dirty water from the back of the machine, which is then vacuumed into the waste tank. Typically, the squeegee is wider than the machine body and plays a crucial role in ensuring the machine operates efficiently. An ineffective squeegee can leave behind dirty water, making its width essential to consider; a wider squeegee covers more area, but if it's too wide for the spaces needing cleaning, it won't function properly. Most scrubber dryers come equipped with a detachable squeegee tool system, which is advantageous for storage. Generally, scrubber dryers with a cleaning width of 17 inches or 500mm and under can pass through standard doorways with the squeegee still attached. However, larger machines, such as ride-ons, may require detaching the squeegee suction tool. Therefore, it’s important to factor in the squeegee width when planning the route for a scrubber dryer.
Scrubber Dryer Tank Capacity
Scrubber dryers are designed with two tanks: one for holding the cleaning solution and the other for collecting dirty water, which is vacuumed up from the floor using the squeegee suction unit. The capacity of these tanks plays a crucial role in determining how long the scrubber can operate before needing to be refilled or emptied. Tank sizes can vary significantly, ranging from 2 liters to over 150 liters. Consider the locations for filling and emptying the scrubber dryer: do you have adequate water outlets for refilling the machine? Compact upright scrubber dryers typically have removable tanks that allow for easy filling at a standard tap and can be emptied by transporting the tank to a designated disposal area. In contrast, larger scrubber dryers usually come with integrated hoses for both filling and emptying.
Types of Scrubbing Brush/Pad options
Scrubber dryers use either a brush or a floor cleaning pad holder (drive board) that employs a rotating motion, or a cylindrical roller brush that functions like a traditional vacuum cleaner. Recent advancements also include oscillating movement. The selection of the cleaning method depends on several factors, such as the type of floor surface, its evenness, and the nature of the dirt, which all play a role in determining the most effective cleaning strategy.
Rotary Brush & Pad Scrubbing: The majority of scrubber dryers utilise a rotary brush or disc cleaning method. They typically have a lower initial cost, are easier to maintain, and replacement disc brushes are less expensive than cylindrical brushes. The rotary motion is a proven technique, effectively cleans most floor surfaces. Most rotary scrubber dryers come equipped with a scrubbing brush, and additional cleaning pad holders (drive boards) can be bought to accommodate color-coded floor cleaning pads. This versatility allows rotary scrubber dryers to tackle various floor types. Softer cleaning pads can be used on delicate surfaces like wood, while harder, more aggressive pads are suitable for concrete and tiled floors. Investing in an extra pad holder drive board enhances the versatility of a scrubber dryer.
Cylindrical Brush Scrubbing: Cylindrical brush scrubber driers maintain less bristle surface contact with the floor compared to disc brushes and can rotate up to three times faster. Many cylindrical models, especially the larger ones, come equipped with a debris tray positioned behind the brushes. This feature collects small debris from the surface, eliminating the need for pre-sweeping before cleaning and reducing the risk of blockages in the squeegee area, which enhances productivity. A cylindrical brush scrubber dryer is a floor cleaning machine that utilises long, rotating cylindrical brushes to scrub and clean floors, making it ideal for tackling loose dirt and debris on uneven surfaces or grout lines. Additional brushes of varying grades are available for purchase, including softer options for delicate surfaces and harder options for more aggressive cleaning. Typically, cylindrical brush scrubber dryers tend to be more expensive than their rotary counterparts. Our advice: if you're uncertain, choose a rotary movement machine. However, if the floor surface is extremely uneven, consider using cylindrical brush scrubber dryers, as they will maintain better contact with the floor compared to rotary disc brushes.
Orbital Scrubbing: An orbital motion scrubber dryer functions through rapid, multi-directional oscillations instead of traditional rotating or cylindrical motions, reaching speeds of up to 2,250 RPM. This vibrational action is transmitted through a cleaning pad, effectively loosening stubborn dirt from floor surfaces, making orbital scrubber dryers ideal for deep cleaning and floor restoration. Unlike rotary and cylindrical models, orbital scrubbers are designed exclusively for use with floor pads and are incompatible with floor brushes. Typically featuring a rectangular deck for the cleaning pads, these machines can clean more effectively near corners and edges. The unique movement of the scrubbing pad allows for quicker soil removal and reduced chemical usage compared to rotary or cylindrical scrubbers, presenting a more sustainable cleaning solution. The flat deck design of orbital scrubber dryers makes them ideal for flat floor surfaces. However, if a floor has undulations, the scrubbing deck may not make consistent contact, resulting in uneven cleaning of certain areas. Orbital scrubber dryers tend to be more expensive than their rotary counterparts, it is also important to consider the ongoing costs of rectangular cleaning pads, which are significantly pricier than the circular pads used in rotary scrubbers.
Traction: Machines with Movement Assistance
Pedestrian or walk-behind scrubber dryer floor cleaning machines can be equipped with traction. This feature means that the machine will have an independent motor that enables self-movement. Typically, the controls to activate, increase, or decrease speed are located on the operating handle or screen, essentially allowing the user to drive the scrubber dryer. For smaller machines, this feature may not be practical, as it adds to the overall cost. However, larger machines with bigger solution and waste tanks often benefit from additional movement assistance due to their increased weight and size. This enhancement helps reduce operator fatigue and improves maneuverability in tight spaces. Traction is particularly advantageous in areas with inclines, when transporting the machine over large distances—such as from one building to another—and in situations where the machine is operated by various users of different shapes, sizes, and strengths.
Sound Level: The Noise Levels of Scrubber Dryers in Operation
When using a scrubber dryer in the presence of other workers or the public, the sound level becomes crucial. Typically measured in decibels, an acceptable noise level is around 63 dBA. Machines powered by mains cables usually produce higher sound levels compared to battery-operated ones. However, advancements in technology have led to the availability of exceptionally quiet floor scrubbers, particularly those with interchangeable 'click-in & click-out' battery options. These innovations utilise digital vacuum motors that operate at significantly lower sound levels than older models
Max Area Performance / Productivity Rate: The area that can be cleaned
This information is especially important when dealing with a large floor area that needs to be cleaned within a limited timeframe, typically measured in square meters per hour. Commonly referred to as the productivity rate, this metric indicates how much floor space can be cleaned in a specific duration. However, the figures provided by machine manufacturers may not always be completely accurate or applicable to every scenario the machine is designed for. Several factors must also be considered, including the distance to filling and emptying locations, the operator's speed while using the machine, and the condition of the floor surface. Some areas might need more intensive cleaning, while others may not. Nevertheless, the productivity rate remains a valuable reference when selecting a scrubber dryer.
To summarise, all scrubber dryers are designed to effectively wash, scrub, and dry floors, ensuring that surfaces are clean and safe. Our guide provides valuable insights into the considerations needed when selecting the ideal scrubber dryer for specific needs.
- For smaller venues with obstacles, opt for a super compact upright machine or a slightly larger compact model.
- For larger areas, such as halls or concourses, choose a walk-behind machine with a tank capacity of 40 liters or more and a scrubbing width of 500mm.
- For extensive cleaning or multiple large areas, a ride-on scrubber dryer is the best choice.
