ROIDMI EVA: Self-Cleaning & Emptying Robot Vacuum

This is a 3-in-1 robot vacuum that also sweeps and mops. This quiet self-cleaning bot can self-empty and hold dirt for up to 60 days. Furthermore, when she mops, she auto-dries. The mop is pressurized and exerts 12 Newtons of force.

She has a 4 liter water tank, and the dual tank system allows for the separation of clean and dirty water. To self-clean the dirty mops, EVA goes back to the base. The antibacterial effect can go up to a whopping 99%! When it comes to the odor-free dust bag, it can actually eliminate 99.9% of the bacteria.

By the way, the waste water tank is 4 liters as well.

Whenever a carpet is encountered, EVA automatically makes a detour. This is not just a feature on paper: this was tested in the trenches.

EVA performs well on tiles, picking up dirt and small pieces of food. On a single charge, EVA can cover 200 square meters (or 2,000+ square feet) of real estate. When tested in a 600 square foot environment, EVA took 3 hours to thoroughly clean. She manages to redock when needed.

You can pause and reactivate EVA if needed. Just press the button on the base!

Spatially aware

EVA tries to be aware of its surroundings. She detects obstacles to make a detour. She has 360 degree omnidirectional LDS (laser distance sensor). She also detects heights to avoid falling off them. Even if she is under furniture or it is dark, she avoids getting stuck. There was no issue running EVA in a lightly lit environment.

EVA cleans in straight lines. 20 mm thresholds should be climbable in vacuum mode, and 15 mm thresholds can be surpassed when vacuum-mopping or just mopping.

Auto-drying mops

Now, you may ask, “How does the auto-drying take place?”

Well, a strong wind is generated through a vortex in order to accomplish fast drying, and the mop pads themselves are both anti-odor and anti-mildew. They are 4 inches and spin at a high speed. More specifically, the RPM (revolutions per minute) is 180. White soft fabric is for floors, and gray polyester fibers are for stubborn stains.

EVA’s vacuuming deserves a five star rating, especially because hair entanglement is not an issue, and its mopping is also great. She mops tiles and wood quite well, and she should take care of food-related stains on tiles with ease.

Smart implementations

Setting up EVA is quite easy, and the first charge took an hour.

You can enjoy voice control with her. She will also give you vocal updates about her status. Additionally, there is a smart LED color screen, and there are also gradient marquee lights. You will get flashing indicators in the case of:

  • The dust bag being full
  • The waste water tank being full
  • There being a shortage of clean water

When the mop is drying, the indicator light will be on. As for battery statuses:

Full BatteryIndicator light [ON]
Low BatteryFlashing indicator
ChargingIndicator light [OFF]

App control

There is an app that is easy to set up as well, and it is user friendly. You can set up scheduled cleaning if you like. We can confirm that this works. Even room cleaning can be tackled in the form of sequence setting. Name rooms as you wish.

If there are areas you would not like EVA to go to, you can set no-go zones, which EVA will respect. Otherwise, there is a spot cleaning mode for specific areas. Hit the spot button onboard EVA to make her go find dirt!

One more thing: updates can happen online OTA (over the air).
