Fey HKS-881 specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
Mopping 1 fact
- Mop type
How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.
- no mop
Navigation and obstacles 1 fact
- Climbs thresholds up to
The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.
- 0.6 in (15 mm)
Robot 1 fact
- Dust bin in the robot
How much dust the robot holds before you empty it. It matters less with a self-emptying dock, which empties the bin after every run.
- 600 ml
