I bought my Roboclean last year i was promised that they would make the first 2 payments. I was promised refilled filters i did not receive any of them. However, they did not. I called and emailed several times until their number was no longer in service. My roboclean stopped working 4 months ago. Less than a year of me purchasing this system. And then number i was given is still disconnected. So i have a system that does not work at all and no one to fix it. I am so disappointed in this company!
