It had MAYBE 4square feet left to clean, and instead of finishing up with the 20% battery power, it went home to the dock and charged for an hour or so, then drove all the way across the house to finish up that tiny area.
The only reason I mention it is that it seems like it doesn’t pick up as much as the Neato, and I wonder if that’s due to the amount of overlap as it passes back and forth over an area, with the D5 making overlapping passes with its larger brush.
Plus, it doesn’t flake out like and start mapping phantom rooms like the Neato Botvac D5 vacuum we tested at the same time as this unit.
All-in-all, we’re thrilled with the mapping and reliable cleaning software of the Xiaomi S5, plus it’s about half the cost of premium vacuums that don’t do the same job nearly as well.
