Q7T+
A robot that vacuums and mops with a flat pad. Its dock empties the bin.
Vacuum and mopPrice band: Under $500
Our take
An under-$500 robot with 10,000 Pa and a self-emptying dock. Its bin is the smallest stated in our list, its mop pad doesn't lift, and it has no obstacle avoidance.
By Emma Walsh
A 200 ml bin sounds like a problem, and on a robot without a self-emptying dock it would be one. It’s the smallest bin stated in our list. The Q7T+ gets away with it because the dock empties the robot for you into a dust bag. The estimate for that bag is seven to nine weeks before it needs changing.
That dock is 21.2 x 17.8 x 25.9 cm, and emptying is its one job: it doesn’t wash or dry the mop, refill water or add detergent. For a robot for under $500, that’s a sensible place to spend the money.
As a vacuum it has 10,000 Pa of suction, and it turns that up by itself when it detects carpet, which is why the Q7T+ is the budget pick in our carpet guide. Its main brush is an anti-tangle one in a comb style, and the single side brush is anti-tangle too. Navigation is by laser.
The 3,200 mAh battery gives up to 180 minutes and takes about 4.5 hours to charge. The robot is 9.9 cm tall, weighs 3.3 kg and makes 65 dB, and it works with the Roborock app, Alexa and Google Home.
The Xiaomi Robot Vacuum H40 is the obvious alternative from the same band. It has the same 10,000 Pa, climbs a 2 cm sill and has a 4-litre dust bag, and its app lets you set what happens at each carpet.
Before you choose, weigh the two things the Q7T+ doesn’t do. Its mop is a flat pad that doesn’t lift for carpet, so this isn’t the robot for mopping around rugs. It also has no obstacle avoidance, so it suits a floor that’s kept clear of cables, toys and socks.
