I had one and it fell apart so many times i got tired of the hassle of sending it back and taking time off to wait for it to be returned, envirodri stated that " i was the only one to experience these problems"
and that the machine did not have a design flaw they said that it should not fall apart because it is used to agitate a prespray i purchased it with the full understanding that this was what i would use it for and they recognised the guarantee when it promptly fell apart, the replacement fell apart too. even the machine they sent for me to use while my machine was being repaired had a huge crack in it, and they still denied that the machine has an inherent problem, i was dismayed with this illogical attitude, they kept telling me that the machine was tested by dropping it onto a concrete floor from three feet and all these other tests, it seems that treating it as a valuable antique as i was doing by the end, damages it
i did start to think it was me and that i was doing something wrong, so when the machine had a brand new case fitted, i sold it. I was aware that many were using it at the time who did not have these problems, so i could not rule out the possibilty it was me, envirodri claimed that one company they supplied had hundreds of them and none of them had ever cracked, mine was the only one, suggesting i was causing it. and that the machine was perfect when they returned it to me.
I replaced the machine with a Host reliant which although it is smaller is better on domestics and unlike the Envirodri the brushes can be changed in about ten seconds instead of the faffing about with those rods for ever bloody silly design to change the brushes, i never got the hang of it.
