Robot vacuums promise freedom from the daily grind of sweeping and mopping but many fall short when they tangle on hair, miss obstacles or need constant babysitting. The Roborock Qrevo QV 35A addresses these frustrations head-on with smart features that make hands-free cleaning actually work. Right now, Amazon has this model down to $399 after applying an additional coupon (from its list price of $649) and hits a new record low that makes premium robot cleaning accessible without the Dyson price tag.
So, where’s the allure in this particular device? Well, it’s in its 8000Pa HyperForce suction power which is downright muscular for a robotic vacuum cleaner. Budget robotic vacs generally top out at 2000-4000Pa so any vac with double that level of power is going to get deep into the fibers on carpeted areas to pull out dirt, hair, and other debris that budget vacs miss.
Why the All-in-One Dock Changes Everything
The docking station takes care of all things maintenance that would have been done by the user otherwise. Itself vacuums the dustbin in a sealed 2.7-liter bag with seven weeks’ worth of dirt in it. As a result, the user gets almost two months with no dustbin in their hands, no exposure to clouds of dirt in the dustbin otherwise. The docking station also keeps 4 liters of clean water for mopping which is able to clean 3,552 sq. ft area, replenishing the water in the robotic cleaner’s water tank in between cleanings. After mopping, the docking station also cleans the mopping cloths and then dries them so that mildew doesn’t form in the cloth.
The tangle-free brush system solves one of the most annoying problems with robot vacuums: hair wrapping around brushes until you have to cut it free with scissors. Roborock redesigned the side brush with an asymmetrical shape that’s SGS-certified for a 0% hair tangling rate, meaning hair simply doesn’t wrap around it. The main brush uses a full-rubber spiral design instead of bristles, so hair and debris slide through without getting caught.
Obstacle avoid technology in reactive tech helps ensure that the QV 35A doesn’t get stuck in a corner or knock over something in its path. The technology assists in avoiding furniture legs, power cords, feet and other obstacles in real time, in contrast to traditional robotic vacuums that would crash into everything in their path.
The two spinning mops operate at 200 RPM and actively cleans floors rather than simply pushing a damp cloth ahead of the vacuum cleaner. The water flow function gives 30 levels to control according to your floors, using reduced water amounts on wood floors but higher amounts on tile floors or linoleum floors. The 10mm mop lift function elevates the mops when the cleaner moves on to low pile carpet floors, avoiding damp floors on the carpeted areas so that it can clean the entire floor in one session without manual intervention.
PreciSense LiDAR Navigation scans your entire house in 360-degree imaging, and provides precision mappings that highlight rooms, positioning of furniture, and floors. The robotic cleaner then relies on these mappings to clean rooms in an optimized manner rather than choosing paths at random. Additionally, it allows storage of mappings for up to four floors, so if it’s a multi-floor dwelling, the cleaner remembers the layout for each floor and cleans accordingly. The intelligent mapping function also allows for zoned cleaning where you can decide to clean either the kitchen or living room rather than the entire house.
At $399 with the discount, the Roborock QV 35A is priced in the middle tier for flagship tech specs.
