Had my Powrflite for 6 months now, So far no problems at all.
Apart from soft body, it marks easier than Ninja.
Over summer cleaned 3 schools with it, one 15000 Sq ft.
Wonderwand,
CFR 5" combi tool, just replaced valve couldn't get a seal kit (Woodbridge).
I would happily clean upholstery with 66 feet of Hide a Hose,
Have not tried further as i only have the 2 high pressure hoses.
Most of the time i use Craftex premium clean, although i have tried
m Power , undecided on that some amazing results, and some total carp.
Nemesis quite impressed, certainly better than M Power.
Nemesis super, seems worse than regular Nemesis.
One step sample with machine, again impressive, but you have to buy too much.
If M Power and One step so good why don't suppliers let you have smaller amounts
instead of seeing you as a one hit wonder.
