British Manufacturing Success Story

We designed, developed and now manufacture a unique washing and scrubbing head for use on compact road and pavement sweepers.

The head was originally conceived around ten years ago. Around this time Councils and cleaning contractors became increasingly concerned about the heavily contaminated water produced during street cleaning going straight into the drains. We knew from our experience providing industrial scrubber driers that using similar technology for street and pavement cleaning would solve this problem.

Our scrubber head is the result and now sells all over the world. Not only do we sell it fitted to our compact road scrubber drier, but it is also sold to other companies selling similar machines. As you can see in the video below it does a great job that no other machine can match.

The story here is simple. At the 2016 Canadian GP meeting a competing car had its gearbox break and deposit all its oil in the pit lane. This was obviously unacceptable so a local cleaning contractor used a machine fitted with one of our head and squeegee kits, built in Market Harborough, to wash the pit lane and collect the waste water and oil. Note the clean line across the white road sector, it’s even cleaner than the surrounding pavement.

British ingenuity and engineering skill at work, brilliant.

New Sweeper

Sweeper in use in gas stationA brand new sweeper has just joined our line-up – the R850. A mid-sized rider this machine replaces the R703 – a faithful servant but now showing its age a little. Major advantages of the new model are its larger size and therefore sweeping performance, strong, unitary construction which means less maintenance and its great price.

Tough Workhorse

The R850 is a tough no nonsense sweeper. This makes it resistant to operator error and easy to maintain. Its simple construction makes it very reliable in even the most arduous applications.

Technological Improvements

1The R850’s direct drive fans are a great example of technology reducing the number of parts and thereby increasing reliability. Add a larger filtering surface and this machine will perform much better than its predecessor in dusty environments. Other improvements include direct drive side-brush motors and a larger diameter main brush. For more details see this page on our website.

Cleaning Capacity

The R850 has a class leading 120 litre capacity hopper which means more sweeping between empties. Cleaning performance is enhanced by the machine’s litter gate and electric filter shakers. Available with either an electric or petrol motor this machine will provide many years of reliable sweeping.

It’s A Steal!

pig-tractorIf you consider that £70 million worth of plant and agricultural equipment is stolen every year with 95% never being recovered it’s clear that agricultural machinery tracking is vitally important to protect your assets.

We have teamed with TRACKER and now offer specially designed tracking products for agricultural machinery and will fit tracking devices to customers machines prior to delivery when required. This simple and cost effective step can reduce your insurance premiums by up to 25% and significantly increases the chance of your getting your plant back if you are unlucky enough to be the victim of theft.

Farm equipment tracking allows you to receive alerts when vehicles or machinery is removed from your premises. This means you can alert the authorities more quickly giving them a head start in recovering your equipment. This gets you back to work faster and minimises disruption and loss of earnings, especially at crucial periods like harvest.

As a leading distributor of Kubota tractors and commercial mowers we see this as a great additional service we are offering our customers. Our partnership with Tracker will be officially unveiled at Burghley Horse Trials, the first weekend of September. Additional information is available on our website in the Kubota section.

Road Sweeper or Street Cleaner?

Patrol Street SweeperGone are the days when a lorry mounted sweeper trundling along our roads fulfilled a council’s street cleaning obligations. With the advent of retail parks, large pedestrian areas and fast food retailing, cleaning activity had to become more effective and pedestrian friendly.

New Breed of Street Cleaners

The first and most noticeable change was the size of the machines. Truck mounted sweepers were fine on the open road but way too big and ungainly for a shopping centre. This brought about the compact street sweeper, a purpose built road sweeper that was smaller, lighter and much more pedestrian friendly. Typically these machines are the size of a small town car and have large front mounted glass cabs giving the operator excellent vision when working in crowded pedestrian areas. Compact they might be but quiet and efficient diesel motors make them perform at a level way above anything previously available.

Pedestrian Area and Pavement Cleaning

Ronda Road CleanerWith more pedestrian areas to keep clean councils turned to these compact road sweepers as a solution. Being sweepers they are great for collecting dust, waste paper, litter and fast food containers. However, the fast food industry presented an additional problem; pavement staining. Drop your cup of coffee on a York stone pavement and you leave a stain. Spill your chips on the pavement, they get walked on, the grease and the ketchup get absorbed; more staining. Imagine this 24/7 in all our major cities and you see the issue.

Scrubbers to the Rescue

Technology that has been in use in industrial scrubber driers came to the rescue. We took the wet wash and scrubbing head from a large industrial scrubber drier and combined it with a compact road sweeper chassis. Add an over-size squeegee and voila you have a brilliant pavement and road cleaner. Obviously other essential changes were made, not least of all the addition of twin water tanks but the end result works, and works brilliantly. Take a look at the before and after pictures of a York stone pavement cleaned with plain water.

Environmentally Kind

Pavement Scrubber DrierIn addition to producing a stunning end result it was pointed out to us that as our Powerflex street scrubber drier collects the waste water it solves another problem: Washing streets with high pressure hoses is done with limited success – the real downside of this approach is that all the dirt and grease is washed into the drains – not popular with the water boards. The Street scrubber drier collects its own waste water, and the grease and filth – result.

 

Choosing the right cleaning machine!

montageWith the vast array of cleaning machines available which one do you choose? This post attempts to give you some insight into the questions you will need to answer. Not rocket science but maybe help you prepare for your discussions with prospective suppliers. Also it might help you avoid overlooking an obvious but important point.

Dry or wet?

Dust and debris that is dry can be collected by a sweeper. Introduce water, grease or oil and the situation changes. So the first consideration is just that, will your cleaning be in a dry environment? Yes; look at sweepers. No; then you will need a scrubber drier or a combination machine.

Cleaning Result Required

If you just want to collect dust and debris and are happy with the appearance of the floor then again a sweeper will do just that. However if you want to remove marks and staining from the floor you will want the scrubbing action of a scrubber drier.

Where do you want to clean?

Working inside vs outside introduces a number of considerations. I addition to the wet vs dry situations we have already considered there is the machine’s motor – if its not electric it will produce fumes. Is this acceptable? If not electric power is a your only way to go. When looking at the sweeper’s power requirement look for synergy with the forklifts you might have on site already. Do you have LPG powered forklifts or red diesel on site for tractors then could your sweeper’s motor take advantage of these resources?

Size of the problem

This is a trade off. Cleaning machines have a theoretical cleaning capacity, this is derived from the machine’s cleaning width and its working speed. So, if you want to clean your warehouse floor you could choose a large machine that cleans it in an hour. A machine with a smaller cleaning capacity might take two hours but cost 30% less. There is your dilemma!

A walk behind sweeper can clean a large car park. But, the time it takes when you consider the speed at which it can operate, the number of trips to empty the hopper and that the operator might be exhausted by the amount of walking would make it unacceptable: Then you have to figure out how much you want to pay to reduce or eliminate these factors.

So there you have it. Not exhaustive and it does not cover everything, but this might be useful as a starting point. At the end of the day talking to your suppliers engineers will be the best way to get just the right machine for your application.

Brushes as in Powered Sweepers

 

main-brushes

Powered sweepers use brushes to pick-up the dirt and debris from the floor and deposit it in the hopper. This post talks a little about the different brushes and their function.

Main Brush

The main brush sweeps dust and refuse into the bin at the rear of the motor-sweeper. Never sweep up string, wire, etc., which can become entangled in the brush and damage the bristles. Periodically check the condition of the brush. The main brush rotates against the direction of travel of the motor-sweeper and throws the dirt and debris over itself into the rear hopper on motor-sweepers having an up-and-over sweeping system.

Adjusting the main brush

The main brush should just touch the floor. While the motor-sweeper is stationary on an even floor the section of floor covered by the bristles should be 3 cm wide. If the main brush no longer touches the floor, or leaves lines of dirt, it has worn down and must be lowered. Once beyond the limit of adjustment the main brush should be replaced, a simple procedure on our sweepers.

Side brush

The side brush sweeps dirt from the edges of floors and from corners, and directs it to the centre of the sweeper where it can be picked up by the main brush. Looking from the operator’s position, the left hand side brush turns clockwise, the right hand side brush turns counter clockwise. On large machines the side brushes can oscillate so that when they meet an obstruction they will swing out of the way. Up to three side brushes can be fitted to extend the sweeping width of a machine.

Adjusting the side brush

Check that the shape of the trace left by the side brush is circular. As the bristles of the side brush wear down, adjust the height of the brush from the floor.  When the motor-sweeper is not in use, the side brush must always be raised above the ground, to prevent its bristles from becoming bent.

Scrubber Drier Technology

Scrubber Drier - MetroEuromec’s range of industrial scrubber driers is available with a low cost attachment that improves cleaning efficiency. The “roller brush” assembly is an option on most of our pedestrian and ride-on models.

The roller brush is a powerful pre-sweep unit. Mounted at the front of the machine it picks up loose debris from the floor before the scrubbing process. This enables scrubbing and sweeping in one pass, without the need for the area to be cleaned with a vacuum cleaner before scrubbing. Cleaning times are reduced by as much as forty per cent.

We are a specialist supplier of cleaning equipment and offer a full range of sweepers and scrubber driers to suit most industrial cleaning applications. Our scrubber drier range comprises nine models which offer the widest possible selection for any commercial cleaning task.

scrubber drier pre-sweep

Walk behind scrubber drier fitted with the roller-brush pre-sweep option

Our walk behind models feature single, two disc or roller brushes and may also be fitted with special squeegees for the cleaning of different surfaces. Standard features include high capacity polythene solution and recovery tanks, suction motor, brush head, squeegee and anti foam device. The largest pedestrian model will clean an impressive 1800 square metres per hour.

Our range of ride-on scrubber driers copes with the most demanding of industrial and commercial cleaning applications. Available with either scrubbing rollers or discs, they all have impressive cleaning performances. Scrubbing widths vary from 800mm to1300mm with the largest having a theoretical hourly cleaning performance of 3,800 square metres.

Metro is a high performance ride-on scrubber drier that has a 6000 square metre per hour cleaning capacity, by virtue of a 1050mm cleaning width and large 270 litre solution tank. Rear wheel drive offers good traction on all surfaces and the drivers position over the front wheel ensures the machine is safe to use in the most crowded environments.

Sweeping Changes

Sweeper cut awayWe supply sweeping machines that use an overthrow sweeping system. So what you might say, well let me explain.

In the illustration you can see how our Brava sweeper is arranged internally. Notice the brush rotation is against the direction of travel and that the collected dirt and debris are thrown over the brush into the rear-mounted hopper. Now this has many advantages over the forward throw system used by other manufacturers.

OVERTHROW SWEEPING SYSTEM:
• The dirt is thrown from high to low, so the hopper can be deeper and have a greater capacity.
• The hopper can be filled to 80-90% of its capacity.
• Collection of light and heavy, small or bulky dirt is easy and equally effective.
• Perfect visibility of the work area because the hopper is at the rear not the front.
• A large range of size and type of dust filters can be used to improve performance in different circumstances.

FORWARD THROW SWEEPING SYSTEM:
• The dirt is thrown up from below and therefore hopper must be shallow
• The hopper can only be filled to 50-60% of its capacity as the dirt tends to collapse back onto the brush
• Collecting light and bulky debris is much less effective (leaves, paper, etc.)
• Poor visibility of the work area because the hopper is stuck out in front of the brush.
• Smaller dust filters are used so as not to penalise visibility, but that reduces the sweeper’s performance.

So there you have it – over throw sweepers are going to collect more dirt and debris in any given situation and they will work longer and more efficiently. Don’t take my word for it – try one and see for yourselves.
