The T-Racer T 450 is great patio & deck cleaner. It will happily clean any large outdoor surfaces efficiently and effectively, without splashing and is up to 50 percent faster compared to cleaning with a spray lance. The reason for this is the twin-jet rotating arm, which ensures dirt removal on large surfaces. The additional power nozzle, which can be conveniently activated when needed using the pedal, also allows effective cleaning of corners and edges. The T 450 also features a special protection grid, which enables the cleaning of Japanese gardens and other gravel surfaces. The pressure can be optimally adjusted by altering the nozzle clearance to the object being cleaned. This means that both hard surfaces such as stone and concrete, and more sensitive surfaces such as wood, can be cleaned. Thanks to the so-called hovercraft effect, the T-Racer is particularly easy to manoeuvre.an be cleaned in no time thanks to the practical handle.
