I like the small footprint of the unit and its quiet operation. It also has a large removal water tank, but it also comes with a drain hose for anyone who wants to unit to drain into a sink or bucket. You dan either use gravity to let the water drain to the hose ot use the pump function to pump the water across larger distance.
I also like that the unit is on easy rolling wheels and has a handle to help carry or move the unit if needed.
If you buy this one, remember to let it sit upright for 24 hours before you set it up. Those instructions are included but not everyone reads instructions.
