Dreame is one of the many newer robot vacuum companies that has been competing for the top spot. One of their flagship vacuums, the Dreame L20 Ultra robot vacuum, is down to its lowest price yet of $699.99 (originally $1,399.99) after a $100 on-page coupon. This is matching the Prime Day deal this vacuum just had, and it is a great one at that. The high-end vacuum comes with many features that will basically allow the robot to run itself (at least for some time).
This vacuum has 7,000 Pa of suction power, 350ml of bin volume for debris, a battery life of 180 minutes (three hours), and some great high-end features. The base station auto-empties your debris and can hold up to 3.2 liters of dust and 4.5 liters of water before it needs to be replaced (about 75 days, according to Dreame). It also automatically cleans the mop and dries it. The mop has an arm that extends to the side to clean farther than a robot vacuum would normally reach. It can also avoid obstacles and detect carpets so it automatically lifts its mop pads to not get the carpet wet (it only lifts 10.5mm, so it won't work on thick carpet).
The L20 is a step up from the mid-tier L10s Plus. The app for Dreame vacuums is solid, allowing you to create rooms and zones, and manipulate the map to merge and divide areas. The vacuum uses LiDAR technology to map your home and lets you have your own custom settings for each room. The app also lets you know when to replace parts and or refill the home base.
If you're looking for a robot vacuum that cleans well, has many features, and has a long battery for a good price, the L20 checks all of those boxes.
