You can expect to spend about $250 for a pet owner’s robotic vacuum. If you have a pet that sheds quite a bit, or if you have more than one animal at home, plan on spending a bit more for a better suction quality of vacuum. The more expensive versions of robotic vacuums designed for pet hair will run you about $100 more than a standard robotic vacuum. The process is relatively easy, once you get the hang of your vacuum. You will need to spend a reasonable amount of time programming your vacuum to understand the perimeters of the intended rooms. Generally, your robot has enough battery power to do a through vacuum through about three rooms at a time before it needs to be recharged.
