You’ve never seen a robot vacuum this powerful with a self-emptying dock at such a low price. Roborock is going big for the last day of Amazon Prime Day. Fresh from the release of its new Roborock Q7 M5+ (with self-emptying dock) last week, the brand is offering Prime members a whopping 42% off.

The Roborock vacuum and mop combo features powerful suction and AutoEmpty technology that makes cleanup incredibly simple.

As Mashable's tech editor, I've been covering Prime Day and Black Friday events since 2019. So, instead of wading through hundreds of the best Prime Day tech deals to find the diamonds in the rough, let me do the deal hunting for you. I am a professional, after all.

We put several robot vacuums from Eufy, Ecovacs, and more through a series of mess tests to see which stood out.

The Roborock Saros Z70 offered a sneak peek at what smart homes might look like in the near future, and it's on sale for Amazon Prime Day.

Roborock has established itself with high-end robot vacuums but a week and a half ago, the brand launched a much more affordable alternative: the Q7 M5. The new product brings Roborock’s quality cleaning technology down to a lower price point and for Prime Day, Amazon is offering an even steeper discount.
