Overall its a very good robo vac and well worth the money. If you can, defiantly go for the slightly more expensive self empty base station as its alot easier and save time compared to the regular robo vac, The only issue I have with it is the latest software update caused some issues with the suction power settings. It seems once the battery % hits around 80-85% the max suction power just refuses to work and the highest it will go is turbo, aka the second highest suction power. Ive contacted eufy about it and we both agreed its probably a battery or other hardware fault so they sent me a replacement robo vac under warranty but made no difference. that to me says it most defiantly has to be a glitch with the latest software update because what are the odds both units have the same issue? Probably pretty dang low.
