Most of the smarter robot vacuums these days can make a map of your home and remember the quickest route through. The Neato Botvac D7 is upping the ante by remembering every floor of your house.
Basic model robot vacuums tend to be pretty inefficient and take a long time to (and a lot of battery life) to clean your floors. Upgraded models make this process smoother by creating an internal map of your floor and remembering where objects and walls are the next time it cleans. This is great on its own, but if you move your vacuum between floors to clean the whole house, then most vacuums lose that memory and have to start from scratch every time.
Neato’s Botvacy D7, on the other hand, has received an update that lets it retain up to three separate floors’ worth of maps in its memory. So, if you move it from the upstairs to the downstairs for a cleaning job, it will still remember where your tables are and work around them efficiently. You can even buy $40 charging stations from the company to put on each floor of your house so you can move it where you need it and then let it do its thing.
