Whatever is said in the review of Aquabot 5 is the same to my experience with Robopurifier 7 their latest model...worst is their customer support who never understands our complaints and acts and says the same thing as theirs is the best..Virtual wall wont function they say its not paired?This machine will never return to its docking station...This machine is not effective for wet cleaning...CUSTOMER SUPPORT JUST ANNOYS U...U WAIT FOR Weeks to get same lame excuse replies ..
