The best Roomba robot vacuum deals before Prime Day aren’t on Amazon

iRobot makes some of the best robot vacuums on the market, but they usually don’t come cheap. Amazon Prime Day, however, is one of the best times of year to buy smart home devices, and robot vacuum deals are already picking up, especially as alternative retailers try to get ahead of Amazon’s main event. Right now, Wellbots is discounting a pair of top-of-the-line iRobot Roomba devices with up to $600 off regular prices.

This top discount applies to the Roomba J9 Plus Combo robot vacuum and mop. It is up to $799 starting at $1,399, a price that is below current offer at Amazon at $200. It’s our favorite robot vacuum for cleaning up pet hair and soft carpets, and the added mopping function is a plus. Also on sale is the Roomba J7 Plus Combo, our top pick for the best poop-detecting vacuum (yes, really) and our overall pick for two-in-one robot vacuums and mop devices. It’s got its price drop to $674down from a retail price of $999 and $25 lower the Amazon price at the moment (if you don’t need the mop function, just vacuuming is sufficient) $400 at Amazon (currently).
