In case the robot is used in a floorplan larger than it can cover with one battery charge, the robot is able to continue cleaning from where it left off the previous session, after recharging its batteries.Models The XV-11 was the first Neato product, released to market in February 2010. This product pioneered the core design and functionality found in all subsequent Neato models.In 2011, a more-expensive enhanced version was developed under contract for German appliance maker Kobold, distributed only in Germany as the Vorwerk VR-100, with some slow expansion later into other European locations.
This model appears very similar to Neato vacuums and shares many parts, but had an additional spinning side brush extending beyond the case edge, for areas not normally reached, and a more powerful suction fan. The bristle front brush and pleated filter were introduced first on these German models and later in 2012 for Neato models. The Vorwerk unit was also powered by a higher capacity, long used in laptop computers, compared to the cheaper (NiMh) battery used in Neato models. Differences in details of the charging process for these different types of batteries, as well as the additional side brush motor, requires different firmware programs for each model's computer. Updates to these programs are delivered separately by each company in case of revisions.In March 2012, Neato Robotics announced its Neato XV-21, a refinement of the earlier models, which is white but has a purple laser head and dust bin cover. This model is designed for pet owners or people with allergies, and features a combination bristle brush/silicone flap beater in a swirl formation and a new pleated filter, which is claimed to remove up to 3 times as much dirt as the original filter before clogging.
However, none of the Neato vacuum filters are, including filters for the XV-21 model (as of June 2012 ).
