At the Basingstoke, we lay out a pre-measured amount of dirt onto carpet, hard floor, and upholstery, then tread this into the floor and leave it to sit overnight. Then, using a set number of passes, we clean the dirty area. We then assess the area, looking at whether it’s sodden, damp, or completely dry. We assess the carpet and upholstery pile to see if it has been restored and lifted, and we look at the color of the carpet and upholstery too. For ease of use, we assess how easy the machine is to assemble and what tools are available (for example, if it comes with an upholstery cleaning tool, hard floor cleaning tool, or pre-treatment wands.
