Very Good: Outlook, ease of use, apps friendly, big water tank, big waste water tank, big dust bag, floor mapping coverage, overall mop/vacuum work quality.
Reminder: Before starting this RoidMi, just remember to enable the floor to be robot friendly, i.e. remove all loose pieces, cables, floor mats, etc. Then, this RoidMi will get the job done, nicely.
It's also the cheapest all-in-1, from the few models I shortlisted.
To Be Evaluated: Durability, how long it would last before the 1st breakdown, repair maintenance cost, repair parts availability.
