Very quiet

I received the Z60 as part of the Get and Create program.  I will include reviews both good and bad to give a fair review of the Z60.

I decided to test the sound of the Z60 for both quietness and pitch.  I have the V50 and have been very impressed by the minimal noise it makes when cleaning.  The Z60 is similarly quiet, however there is a different noise and pitch with the roller mop compared to the mop pads.  While I notice the noise difference, it is not annoying - just different.

I thought a good test would be to focus on how my dogs react to the sound.  They are both older and can get spooked by sounds or moving objects.  It worked out well today that Ollie was more curious than normal to the Z60 running.  To be fair, I have only had the Z60 run a couple of times since I received it, so I don't think they have had time to acclimate to the sound.

The videos I have included are the start of the clean cycle and then vacuuming of the living room directly in front of the sofa where the dogs are sleeping.  The Z60 is quiet enough that it doesn't disturb them or bother them if they are close to it.  In both videos, you can hear the Z60 running.  Again, the sound is not too loud and the pitch is not annoying at all.

I'm impressed with the sound level and confident that I could have it running at night without waking me up or freaking out the dogs with strange noises in other parts of the house.
