Bob actually works! Had my doubts, but he wandered around for 20 minutes and got a lot of terrier and cat hair. Takes a bit to get used to Bob's motoring patterns. Bob does not fit under the sofa, chair and a half or the overhang of the kitchen cabinets, but I can live wi/that.
Getting Bob to stable up on his charger is takes a few tries. Make sure the charger is very stationary and against wall, not a few inces off as written in directions.
Lots of pet hair means dumping collection thing several times during session.
Best if Bob works a little everyday.
Best packed appliance ever purchased. All clearly labeled parts and good diagrams in manual.
