Excellent functions.  Only criticism is the plastic rollers on tje power head ate held with tiny weak screws and break easily.  So be careful about banging the plastic power head into anything.   Dyson needs to beef thos part up as I find the rollers important at maintaining the most effective height of the power bar to the floor for effective suction.  

Everything else is excellent and I cannot praise enough just got good this vaccuum is at keeping my home clean amd healthy.
