Frequently Asked Questions (FAQ)
Why does my Roidmi Eve Plus no longer return to the charging station?
The most common problem is an aging battery. If the remaining capacity drops too quickly below a critical level, the robot shuts down before it can reach the station. Replacing the battery solves this problem in most cases.
My Roidmi robot vacuum stops in the middle of the room, what can I do?
This strongly indicates a defective battery. Even if the app showed a high charge shortly before, the voltage can collapse under load. Check the charging contacts for dirt and perform a reset. If the problem persists, a new battery is required.
Can I replace the battery in the Roidmi Eve Plus myself?
Yes, the replacement is relatively easy for technically skilled users. Typically, the robot's bottom cover must be unscrewed to access the battery compartment. The battery is connected with a plug and can be simply unplugged and replaced.
Does this battery also fit robot vacuums other than Roidmi?
Yes, this battery, designated H18650CH-4S2P, is a standard model also used in many robot vacuums from brands like Viomi, Lydsto, Proscenic, and Others. Always compare the model number and connector shape before purchasing.
How long does a new battery for the Roidmi Eve Plus last?
A new, high-quality Li-Ion battery typically lasts 2 to 3 years or several hundred charging cycles, depending on usage frequency and charging behavior, before its capacity noticeably declines.
What do the designations 4S2P and 18650 mean for the battery?
'18650' describes the size of the individual cylindrical battery cells (18mm diameter, 65mm length). '4S2P' means that eight of these cells are installed in the battery pack: four connected in series (for the voltage of 14.4V) and two such strings connected in parallel (to increase the total capacity).
