have been using the aztech vc3000 for about 2-3 weeks now.
Batt life is somewhat unpractical. Manual says switch off docking station if not in used. the robot must be docked all the time because if you don't, batt will eventually die out and it won't auto charge on its own. then machine's time will be lost and you need to configure it again. You need the machine's time because it has a "scheduled cleaning option." so, if you don't dock it always(may degrade battery life like all electronics), then, it can't maintain system's time with real time.
also, it doesn't recognise barriers so well, sometimes it just keeps bumping into surfaces and then scrape against them as it tries to turn itself out of it. *heartpain* when you see the scratches on a newly bought machine.
other than that, price at 199(not including further discount due to Lazada's offer) quite ok for that.
Side track a bit, Lazada's delivery and pricing totally beat our local electronics store.
Lazada may deliver the next day upon ordering. Local stores deliver 6 bizness days later.
Lazada is cheaper. Local Stores already discounted price also more exp.
