Ecovacs X8 tank problem?

Check the float first.
3DBlackMT replacement float next to an Ecovacs X8 water tank module #01 Compare the shape

If your Deebot X8 is not mopping properly or the tank is not detected correctly, check the small float first. Comparing the shape can help before replacing the complete water tray.

Typical symptoms

This page does not replace the manufacturer’s repair instructions. It helps you narrow down the issue and avoid missing the float as a possible cause.

1

Mops dry

The robot runs, but the mop pad stays noticeably dry or receives too little water.

2

Tank seems okay

There is water in the tank, but water delivery feels unreliable or uneven.

3

Small part missing

During cleaning or disassembly, a small part in the tank can get damaged, jammed or lost.

Quick check

Check first, then replace

1
Remove the tank.

Only inspect the water tray/mop tray when the robot is switched off and safe to handle.

2
Find the float.

Check whether the small part is present and sits in the right place.

3
Check movement.

The float should not be jammed, broken or visibly deformed.

4
Compare the shape.

Compare your part or installation point with the product photos before ordering.

Does this part fit your tank?

The most important step before ordering is comparing the shape. This page is meant to prevent wrong purchases, not just push a sale.

It may fit if ...

  • you use an Ecovacs Deebot X8 OMNI or X8 Pro OMNI,
  • the float in your water tray is missing, damaged or jammed,
  • the shape of your existing part or installation point matches the photos,
  • you are looking for a compatible replacement part instead of a complete water tray.

Please do not buy if ...

  • you expect an original Ecovacs part,
  • you have a different Deebot model and have not compared the shape,
  • the pump, seal, electronics or another component may be the cause,
  • you expect the complete water tray, the robot or additional accessories.

Why a 3D printed replacement part?

For small plastic parts, 3D printing can be the right approach: low volume, quick availability and no need to replace a large assembly.

Practical

Made for users who want to replace a small damaged or lost part.

Targeted

The focus is the float, not replacing the complete water tray or mop tray.

Transparent

Compatible replacement part from 3DBlackMT made from PETG. Not an original part and not affiliated with Ecovacs.

FAQ

Short answers for visitors who want to know whether issue, tank and replacement part match.

Is this an original part?

No. It is a compatible replacement part from 3DBlackMT and not an original Ecovacs part.

Which models?

Intended for Ecovacs Deebot X8 OMNI and X8 Pro OMNI. Please still compare the shape of your tank with the photos.

What do I receive?

You receive one replacement float. No water tray, no robot and no other shown parts.

What should I check?

Model, installation point, existing float, movement and possible damage. If unsure, ask before ordering.

Does this fix everything?

No. If the pump, seals or other components are affected, the cause may be somewhere else.

Why 3D printing?

For small low-volume spare parts, 3D printing is practical: targeted, quickly available and without replacing a complete assembly.

Important before ordering

Compare your existing part and tank with the product photos. If you are unsure, ask via Etsy before ordering and keep a photo of your tank ready.
