Recently, I bought a new vacuum and mop robot, but I noticed that it struggles to climb over obstacles around the house. In my case, a clothes drying rack.
Every time it reached the rack, the robot would try to climb over it and either get stuck or insist on passing through the exact path where the obstacle was.
You can download the 3D model (.stl format) from here: Vacuum cleaner ramp
To solve this, I designed a dedicated ramp that attaches to the bottom of the drying rack and fits it perfectly. The ramp can be moved from place to place without worrying that it will fall off.
The pipe diameter is 16 mm, so I designed a custom ramp specifically for it.
