The Dyson DC23 Turbinehead is a powerful canister vacuum, for all-around performance. DC23 Turbinehead features Dyson Level 3 Root Cyclone technology, the most efficient technology for capturing microscopic dust. Turbine head refers to the air-driven brush bar, which spins up to 90 times per second, and is ideal for cleaning medium and short pile carpets. It can also be turned off for hard floor and delicate surfaces.DC23 Turbinehead has a lightweight adjustable wand. An extension tube adjusts to the length you want, and it is sealed, to maximize airflow and increase suction at the floor tool. It also features a detachable handle, which allows you to fit tools directly to the end of the hose, for cleaning in tighter places.

Dyson refurbished vacuums have been stripped down, cleaned out, reassembled and thoroughly tested. They're restored to a fully functional condition. In short, they are everything a Dyson machine should be- they work properly and don't lose suction. Dyson refurbishes vacuums that are returned to us by retailers or consumers. Refurbishing these machines, rather than disposing of them, means that the parts and materials are re-used instead of wasted. When a machine comes to us to be refurbished, it is first stripped down as far as necessary. Components removed from the machine that meet our high standards of quality are kept and cleaned. Most damaged or broken components are sent away for recycling. The core of the machine is thoroughly cleaned and new parts are added to replace damaged or cosmetically unacceptable parts discovered during the stripping down process. Just like our brand new machines, the rebuilt machine then undergoes a comprehensive series of electrical and performance tests to ensure that it works as it should. For our vacuums, one of the tests carried out is a suction test. All refurbished vacuums are electrically tested in compliance with electrical and safety requirements. One of the primary differences between a new Dyson machine and a refurbished Dyson machine is its appearance- a scratch here or there or a slightly clouded bin may provide a clue that it has been previously used. After it has passed all of the tests, the machine is then packaged and sent out. All Dyson refurbished vacuums come with a 6 month parts and labor warranty.
