eufy RoboVac 11S Slim Vacuum Cleaner is on sale on Amazon now. Down from $229.99, it is priced $159.99 with $70 discount.
I got this one -- it's $230 new and 100% worth every penny. She's not always the best at finding her "home" at the end of a cleaning cycle, but that's my only complaint and it's partially my fault anyways for not putting her dock in a more easily accessible spot.
