Since each accessory will contain the Roomba for about 25 to 30 minutes the (stock) battery won't last for more than about 80 to 90 minutes. So using 4 to 5 LH/VWs will require a battery capacity of 120 to 150 minutes.
I checked and yes, Roomba takes 25 minutes to clean a zone. After this it starts to search for a lighthouse to move to the next zone. Fully charged 790 could work up to 100 minutes => 4 zones, not more.
Now I devided the apartment into 4 zones. Zone3 and Zone4 could be transformed into a single zone if I remove Lighthouse 3. Tommorow I will check if Roomba could cope with all 4 zones.
