Gergo A.: Dear Seller! I am Gergo from Hungary. I am the manager of a cleaning company. I would be interested in the machine. I have to clean 50,000 square meters of polished concrete floors/day. Please send details or a video in action: - suction engine? - rear suction rail lowering motor? - brush drive? - what is the condition of the brush? - what is the condition of the wheels? - what is the condition of the batteries, how many operating hours do they have? - is there a scrubbing brush and ped holder? - how many operating hours does the machine have? - possible errors? - lifting and emptying the garbage container? - when are the drive belts? - when was the hydraulic oil changed? - filters? suction? Thanks

Gergo A.: one more question: plate brush or roller brush?
