That is good news.
Im sorry if i helped sturr things up,
As a Manurfacturer/supplyer it is frustrating when we come up with something that is a handy tool at a decent price, and are accused of passing off, while i admit its not a new idea (because of the 1976 pattern) , and been around for thirty something years, by no means have we tried to pass off, we think the concept of a retrofit end is a good one so domestic window cleaners can use their existing investment (their WFP).
We have also sold them to traditional window cleaners that carry the hose end up the ladder to clean, aswell as to WFP window cleaners, aswell as being great for gully's, lawns etc.
So i am safe in the knowledge that when somebody buys a Polarvak they know they are buying a Polarvak, and no other.
So it would be nice to just be left alone and not pesterd by another supplyers solicitor claiming nonsence, before this when we were asked if ours could go 45' + (commercial) we would say no but heres a company in London that produce a totally different concept better for high guttering, because i think theres plenty of market for all companies involved with vacuum cleaners that are tweaked to clean guttering.
We have worked with Numatic on parts of our system i.e the wet/dry unit, the cuff fit cyclone inlet, the end tooling, we buy the hose, and manurfacture the retrofit part, which i think im right in saying no one else has done, however it has not been patterned because i think our prices are competitive enough that why would somebody copy.
If other companies wish to, they can because we hope that our brand and after sales service will mean we can have a small share of the market.
