Gone 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
With 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.
In 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.
