Review: HYDRA S7 Robot Vacuum (The Best Robot in 2020??)

I am a first time owner of Robot vacuum and this post is reviewing on the latest HYDRA S7 Robot Vacuum with mop.

The seller did a great comparsion table with one of the best robot vacuum in the market which is the Roborock S6.
Head to Head comparsion of the spec, clearly the latest Hydra S7 Robot is a winner.
Alot of graphical image is being used to illustrate the specs and capability of the Hydra S7 too which you can easily find it over here.

After using it for 2 weeks, I am very happy with this Hydra S7 (Vacuum + Mop feature) given that it is just SGD300+ in Qoo10 comparing to Roborock S6 at SGD599 in Qoo10.

It is a no brainer to buy Hydra S7 that have a better spec and nearly 50% cheaper than the famous Roborock S6.


1) Great job done in SWEEPING + MOPPING 

Did a few rounds of housewarming, I would say Hydra S7 did a great job in sweeping + mopping the sticky floor back to its clean state EVERYTIME.

Thanks to its 2300 Pa Suction power + Large 560 ml water tank + Large mop rag.

The amount of dirts collected in the dust box and mop rag shows how efficient and effective Hydra S7 is.

2) Good cable management

I love it that I can coil and hide the excess cable inside the docking so that it look neat and tidy.

3) Easy to setup and user friendly APPS

I did not experience any difficulty from unboxing to kickstart my very first cleaning. It is very user friendly.

4) Indicator LED light status

Aside from looking stylish, it also have LED light status that is visible to tell you the status of it if it is charging in process, battery full and etc.
It is also clever enough to warn you with RED LED light if let say you insert a water tank but did not insert the mop rag.

5) Product consumables lifespan

In the app, it also show you the lifespan of its accessories so that you will know when it is time to replace it.

6) Mini brush

This mini brush is very useful especially during emptying the dust box. 
A deep thought was given to hide this mini brush under the flip over of the robot make it very user friendly so that it will not get missing.

7) Great unboxing experience

Instead of using those thin cardboard like most others, the cardbox used is of good quality and thick. This give a great protection to the Hydra S7 robot vacuum against the rough handling during the delivery.

All items are placed nicely and neatly.
Very pleasant to the eyes too.

8) Super value for money
Hydra S7 at SGD300+ in Qoo10 VS Roborock S6 at SGD599 in Qoo10.

A better spec Hydra S7 selling at nearly 50% cheaper than the famous Roborock S6.


1) Floor is WET although the 'Water Seepage' setting is set to "Low" in mopping mode

2) Battery drop 20+% after 8 hours of standby/sleep mode

Even in standby/sleep mode for 8 hours, the battery dropped 20+%.
To solve this, I just switched off the robot before I went to bed and on it back before I leave the house.

3)  Schedule clean does not work without WiFi

If you have the habit of switching off your WiFi when you leave your house, the robot will not be able to start the cleaning with your pre-set timing. 
To solve this, I bought a timer plug for my WiFi router where it will auto switch on and off at your specific timing.

4) Stuck if you have floor cloth

If you are using large floor carpets, the robot have not issue going over it.
However, if you are using those lightweight floor cloth, then the robot will get stuck with it.
To solve this, you will need to set virtual wall zone (no go zone) OR remember to remove the floor cloth.
I think most robots are facing this issues at this moment.
