The heart of the machine is the motor. Solidly built and very easy to start. But a screw was missing in the main fan cover plate, and this allowed water content from damp leaves to leak out over the machine when using it as a vac. Not a big problem, just caused a mess.
Biggest gripe is the way the tubes fit onto the motor. Different tubes are used depending on if you are using the unit as a vac or a blower. The design means the tubes have to be plugged in and then rotated 90 degrees to lock in place. This is not easy to do! I put some grease on to lubricate, but this just attracted grit etc.
I wanted the machine primarily as a vac. We have a chestnut tree which drops enormous leaves this time of year. I might have been asking too much (it is commercial grade?) but slightly damp leaves easily jammed in the outlet to the bag. This meant removing the pipe, not easy to do - see above! And if you didn't clear right inside the fan, then the machine would quickly block again.
But it works well on drier smaller leaves. Really good power and the collection bag holds a lot of mulched leaves. Emptying the bag is best done by leaving it attached the the machine, as to remove it from the pipe is a bit of a faff, and to remove the pipe from the machine is tricky - see above. Bag itself is good quality, good strong zip.
All in all good, but let down by the quality of the pipes. The plastic used is poor quality and because they flex so much, that creates the fitting issue.
