Kirby Demonstration Sight Glass \u2013 Visible Results for Mattress Cleaning<\/h1>\n

With the Kirby demonstration sight glass, you can immediately see what your Kirby removes from a mattress, carpet or upholstered surface. Thanks to the transparent housing and black collection filters, dust, hair and other fine debris become clearly visible. This makes this Kirby accessory particularly suitable for demonstrations, professional mattress cleaning and checking cleaning results.<\/p>\n

What is the Kirby demonstration viewing glass?<\/h2>\n

The Kirby demonstration viewing glass is a transparent accessory that temporarily replaces the standard Kirby outer bag during a demonstration. You then place a round black collection filter inside the viewing glass, allowing the vacuumed dirt to be collected and clearly displayed.<\/p>\n

During cleaning, the intake air flows through the transparent demonstration glass. As a result, you can immediately see how much dirt is being removed from a mattress or upholstery, for example. Especially when used in combination with a Kirby mattress cleaner<\/a>, the viewing glass provides a clear visual check of the cleaning results.<\/p>\n

Easy to install and use<\/h3>\n

The demonstration glass is quick and easy to install. First, remove the Kirby outer bag and then place an original black collection filter inside the viewing glass. Next, attach the transparent viewing glass to the Kirby and you can begin cleaning.<\/p>\n

The vacuumed dust and dirt then collect on the black filter. This creates a clear contrast, allowing you to see the results immediately. After the demonstration, remove the viewing glass and reinstall the standard outer bag.<\/p>\n

The Kirby demonstration viewing glass is intended exclusively for demonstrations and short cleaning checks and is not designed for everyday vacuuming.<\/p>\n

Original collection filters for the Kirby Demonstration Sight Glass<\/h2>\n

For proper operation, we recommend using only the designated black Kirby collection filters. These filters combine good airflow with clearly visible cleaning results.<\/p>\n

Alternatives such as paper or cloth may become clogged more quickly. As a result, airflow may be reduced and the demonstration system may operate less effectively.<\/p>\n

The Kirby demonstration viewing glass comes standard with 200 black collection filters. For professional or regular use, you can also order a roll of 1,250 demonstration filters. This bulk pack costs \u20ac120.00 and may have a slightly longer delivery time.<\/p>\n

Suitable for various cleaning applications<\/h3>\n
