This is brilliant on flat surfaces but if you have patterned rugs it's no good. My kids ran the battery down in a bit over 10mins doing their rooms so I had to wait for over 2hours while it charged before I could do the rest of the house. Would not recommend for families for this reason. When I did get my turn I found it heavy, both my wrist and back were sore by the time I finished. Also really stressful when the battery light starts flashing when you're just about done.
