Scissor lifts and other ground work
For flat-surfaced, low-rise buildings, ground-level access from a scissor lift is a preferred option for window cleaning. Set up at the base of the building, the scissor lift is driven from the ground and the platform travels up and down.
For ground floor work, we bring day porters. When everything is hand-reachable, no special equipment is needed. Of course, ground floor windows have to be cleaned more often than higher ones because they are in everyone's line of vision and because their proximity to the roads attracts more dirt.
