The PowerDetect robot vacuum is powered by 3 deep-cleaning technologies that enable the robot to maximize performance by sensing mess level, floor type, and edges & corners. DirtDetect sees even the hidden debris and automatically increases suction and cleaning passes to remove the mess on carpets and hardfloors. The only robot with NeverStuck technology, it will navigate around obstacles AND lift itself up and over thresholds and onto thick carpets. Not only can the robot deep clean, but you also do not have to worry about it getting stuck. PowerDetect finishes the cleaning mission every time and with each clean will empty itself into its bagless base that contains a HEPA Anti-Allergen Seal trapping dust & allergens inside.
3 DEEP-CLEANING TECHNOLOGIES: Three powerful cleaning technologies detect and react to hidden dirt, different floor types, and edges for up to 50% better debris pickup*. (*vs. Shark RV900S)
WON’T GET STUCK FOR UP TO 2x MORE COVERAGE*: NeverStuck Technology ensures you don’t have to babysit your robot. It lifts & lowers to maneuver over obstacles, across thresholds, and easily avoid getting stuck (* Based on internal stuck protocol vs. Shark RV750).
SENSES THE DIRT YOU CAN’T SEE: DirtDetect Technology senses hidden debris and automatically boosts suction.
CLEANS EDGES AND CORNERS: EdgeDetect uses blasts of air to pull debris out from corners and edges into its cleaning path delivering 50% better edge cleaning* (*vs. RV2600 with EdgeDetect turned off)
MAXIMIZED PERFORMANCE ON ALL SURFACES: Shark’s FloorDetect Technology detects different surfaces and optimizes brushroll engagement with the floor to maximize cleaning performance based on the floor type.
Customers find the robotic vacuum performs well, with one noting it’s better than the Roomba. However, reliability and cleaning performance receive mixed feedback – while some say it works amazing and does a great job, others report it stops working in the middle of the job and cleans randomly. The value for money, stability, mapping, and noise level also get mixed reviews, with some finding it worth the investment while others say it’s not worth the money. Moreover, durability is a concern as units break after 8 months of use, and the 45-day tank doesn’t last a week.
