T.L.Killis was established in 1964 and has offices in Sheffield and Chesterfield, UK.
For 25 years they have sold window cleaning products to traditional window cleaners. The vast majority of the company’s window cleaning business over the pass 7 years has switched towards pure water window cleaning systems and WFP’s.
Traditional window cleaners started to enquire about using pure water and a pole rather than a squeegee, applicator and ladder and asked T.L.Killis if it could provide them with a system to get started.
A spokesman for the company said, “We looked at what was available on the market and decided straight away that the build quality of certain products out there was diabolical.
A cheap sack barrow with a plastic storage box screwed on it. This was the main reason we decide to manufacturer our own range of trolleys. Our market research told us that a traditional window cleaner wanting to change the way he cleaned windows was going to be a big step, so could it be done without having to spend a serious amount of money on a van mounted system?”
The first trolley the company built and still its best seller carries a DI resin vessel, so it will purify the water as you use it and will run up to eight hours on a full charge. It will push water down the micro bore hose up to 100 mteres in length, up to 65 foot in height.
” This meant that a window cleaner wanting to get started in pure water window cleaning could do so for under £1000,” continued the spokesperson. ” Most traditional window cleaners in our experience work from a car rather than a van. So the idea of being able to take several 25 litre bottles of tap water and the trolley with them is very appealing. Remenber – this trolley de-ionises the tap water as you go. Just replace the bottle when empty.”
“Feedback from our customers told us that the most common practice is to clean the top windows with the pole and the bottom windows with the traditional way, saving water and resin usage. One important comment made by most window cleaners is that after a hard days work, by using the pole rather than a ladder, they no longer suffer from aching knees.”
One of the questions T.L.Killis was frequently asked by window cleaners is; will my customers accept the change in the way their windows are about to be cleaned?
“The answer is that 90% will accept, but unfortunately some of the old fashion traditionalists take a lot more convincing,” said the spokesperson, “But when they realize that they will get their window frames cleaned for free they generally come round. But I would be lying if I said everyone would be converted.”
After the success of the DI resin trolley, the company began to manufacturer a range of reverse osmosis trolleys bot in 12 and 230 volt. ” Our trolleys will produce 1000’s of litres of pure water very cheaply and quickly – up to 6 litres per minute at 125psi from the 230 Volt machine and 3.5 litres per minute at 85psi from the 12 Volt machine. The average cost of DI resin used by a reverse osmosis trolley is 40p per 1000 litres of pure water produced.”
These systems are popular with contractors who do a lot of site work and need to produce an unlimited supply of pure water. Two people can work from these machines effectively all day without running out of water, providing the machine is connected via a hose to a water supply.
Window cleaners also buy these trolleys because they can rapidly fill their existing van mounted water tanks very quickly.
