This machine has been sold and marketed under many different guises and colours by different manufacturers.
It does, however, have a long history being known as the Hako Homeclean in light lilac colour with a lilac tinted dome.
Taski used to call it the Aquamat 10; it came in orange and included a smoky-brown dome.
The WAP model was yellow and the Nilfisk-ALTO was blue. Each usually came with a smoky-brown dome.
