Dyson is holding an early Black Friday sale on vacuums and related products. Sure, Black Friday isn’t for another month, but who are we to turn down a fantastic deal? To that end, the Dyson 360 Vis Nav robot vacuum is a whopping $600 off and down to $400 right now. That’s $100 less than its previous all-time low and the cheapest we’ve seen it.

Pick up one of the strongest robot vacuums we’ve tested for more than half off.

$400 at Dyson

Dyson was pretty late to the robot-vacuum party, but its entry was (and remains) one of the strongest in the category. It doesn’t have a lot of bells and whistles like a self-emptying base or mopping capabilities, but it makes up for that by having probably the best suction power of any robovac we’ve tested. All kinds of debris will fall in its path: dirt, dust, food crumbs, pet hair and more. It also has excellent obstacle avoidance, so you’ll rarely — if ever — have to dislodge it from getting stuck on the edge of a carpet or wedged in between furniture. Dyson’s mobile app is easy to use as well, so if you’re looking for a robot vacuum that does its main job incredibly well and you don’t mind skipping on some extras, the 360 Vis Nav is a great option.

Cordless vacuums are also a part of the sale. Take the Dyson V9 Motorbar cordless vacuum on sale for just $270 at both Dyson and Amazon, which is a discount of $330. That’s more than half off. Dyson devices are all over our list of the best cordless vacuums, and for good reason. The company makes effective products. The V9 Motorbar has been designed to clean all floor types, in addition to upholstery. It’s also been engineered to squeeze into tight spots, which is great for hitting those oft-neglected parts of the home.

The suction power is on point and the battery lasts for 40 minutes before requiring a charge. That’s just enough time to vacuum a standard-sized home if you don’t stop for too many breaks. The V9 is getting a bit long-in-the-tooth. If you want a newer model, the V11 Extra is on sale for $400, which is a discount of $260. This one boosts the suction power and increases the battery life to 60 minutes.
