Due to the technology used and advanced features of robot vacuums, they are generally priced higher than traditional vacuums. The customary price of robot vacuums would range from $400 to $1,300. However, there are exceptions. One robot vacuum that has a low price tag is the iRobot Roomba 694, which is usually priced at $180. Said robot vacuum is included in this list so do not judge a model solely based on its price. On the other hand, one robot vacuum that is priced high is the Roborock S7 MaxV at around $1,400. Comparing the Roomba 694 and the Roborock S7 MaxV based only on price is quite unfair though as it offers varying features and functions.
