Mains power and performance and plenty of both, the outstanding specification of the TT4045G is, without doubt, to the highest standard both in terms of design and performance. The big advantage of cable machines is the amazing power provided by mains operation, three times that of battery machines and due to the lack of costly batteries and 24V components, the machines are truly cost effective, almost two for the price of one. Cable machines are used extensively in many industrial applications where floors are quite often rough and exceptionally dirty.
