Robot vacuums can be a big help around the house by automating a regular chore, but they can be pretty expensive. That’s why it’s a wise decision to wait for a shopping event like Amazon Prime Day to buy one,

As of July 1, this impressive device is $50 off and is now available for just $399.99. That's the lowest-ever price according to price tracker camelcamelcamel.

Robot vacuums are incredibly useful, but tend to be expensive. Fortunately, I found some deep discounts leading up to Prime Day, coming up July 8-11 this year.
