Robot Vacuum and Mop with Multifunctional Dock
Roborock QV 35S Review

10,000Pa suction | 360° LiDAR | Structured-light avoidance | 200 RPM mops | Maps up to 4 floors

Overview

The Roborock QV 35S is a robot vacuum and mop with 10,000Pa HyperForce suction, LiDAR navigation that scans 360° and structured-light Reactive Tech obstacle avoidance. It maps up to 4 floors. Its two liftable spinning mops turn at up to 200 RPM and lift automatically for carpet. Its spiral-designed rubber floating main brush is an all-rubber anti-tangle design, and it has an arc-shaped asymmetric side brush.

The Empty Wash Fill Dock empties the robot and empties more often when it detects a lot of hair, washes the mops in a three-stage process, dries them with cold air and refills the robot’s water tank; you fill the dock’s clean water tank with cold tap water by hand. The 5,200mAh battery can charge off-peak, the robot climbs thresholds up to 2 cm, and it works with Amazon Alexa, Apple Siri Shortcuts and Google Home.

Setup & Installation

Press the dock base on firmly until it clicks, connect the power cord to the back of the dock and keep the spare cord in its storage slot, then click the mop axles into the robot. Place the dock on a hard, flat floor (wood, tile or concrete) flat against a wall, leaving at least 0.9 m of height, 0.4 m of width and 1.2 m of space in front, and fill the clean water tank with cold tap water only. Hold Power/Clean to turn the robot on, wait until the power light is steady, put the robot in front of the dock and press Dock to send it in to charge.

Download the Roborock app. Open the robot’s top cover, hold Power/Clean and Dock together until you hear “Resetting WiFi” and the Wi-Fi light flashes slowly, then tap “Add Device” or “+” in the app and follow the in-app guide. The robot connects on 2.4GHz Wi-Fi only. Roborock says to vacuum at least three times before the first mopping run.
