I use the nozzle for smooth floors and carpet floors. The suction power (energy consumption!) I was able to reduce significantly with better suction result.
Weak points are:
o glides wear out I have the slides now with adhesive felt pads (chair glides) replaced. Would be desirable corresponding receptacles at the bottom of the nozzle, so that the bonding would be more reliable.
o the hinge is relatively thin ausgeührt and therefore already broken (which have been able to repair with a 35mm PVC pipe and epoxy.
For this, the function is perfect. In addition, the nozzle is relatively wide saves time.
