Neato Robotics has announced a new model of robotic vacuum, the Neato XV-21 Pet & Allergy automatic vacuum cleaner, which is aimed at helping customers control allergens and pet hair in their homes. Compared to the older model Neato robots, the XV-21 boasts: Lower noise, a new bristle brush, and a new filter with better air flow which is designed to catch smaller dust particles. We reviewed the Neato XV-11, here.

Neato’s press release about the XV-21 makes the aim of this new vacuum clear. It mentions that the Asthma and Allergy Foundation of America recommends that people who suffer from allergies can help prevent outbreaks by reducing pet dander, hair, and feathers in their home, and also recommends vacuuming frequently.

By scheduling the robot to clean automatically while they aren’t home, an allergy sufferer can reduce their exposure to airborne dust, pollen, and dander. The press release also mentions that it’s easy to schedule the robot to vacuum every day.

Besides aiming to reduce pet hair and allergens around the house, Neato has updated the look of the robot vacuum with a futuristic purple and white design, that is also kind of simultaneously retro. The new brush is designed to reduce the noise made by the robot, make it pick up hair better, and also make it work better with hard floors.

The new vacuum is expected to be available at the end of April 2012 and will have a manufacturer’s suggested retail price (MSRP) of $429 US. Owners of past models can upgrade their robots, which will be compatible with the new features. The new filter will have a MSRP $29.99. The Pet and Allergy Upgrade Kit (which includes the new bristled brush) will have an MSRP of $59.99. To use the new items, however, earlier models (XV-11, XV-12, and XV-15) will need to be upgraded to the newest firmware, which as of this writing is 2.6.
