what's the right way to store the braava jet m6 if i'm not using it for a few months?

Diagnosis

The iRobot Braava Jet M6 is designed for continuous operation, but long-term dormancy creates two primary points of failure: battery degradation and fluid stagnation. If left on its Home Base for months, the lithium-ion battery can experience "trickle-charge fatigue," where constant topping off reduces the overall lifespan of the cells. Conversely, leaving the robot powered on but off the charger leads to a deep-discharge state; once the voltage drops below a critical threshold, the onboard protection circuit may permanently disable the battery to prevent fire hazards, rendering the unit "dead" and unable to charge.

Beyond the electronics, the fluid delivery system is prone to crystallization. Residual cleaning solution in the internal pump and the narrow spray nozzles can dry into a hard crust. When you eventually restart the machine, these crystallized deposits can clog the spray mechanism, leading to "Dry Mop" errors or a complete failure of the Jet system. Confirming a storage failure usually manifests as a robot that won't power on despite being on the charger, or a robot that moves but fails to dispense liquid.

How to Fix It

To ensure the Braava Jet M6 survives a multi-month hiatus without hardware failure, follow this precise decommissioning sequence:

1. Power Down: Move the robot off the Home Base. Press and hold the HOME button for exactly 10 seconds. You will see the indicator lights flash and then go completely dark. This puts the unit into a deep-sleep state, preventing the battery from draining through standby power.
2. Fluid Purge: Empty the remaining cleaning solution from the tank. Fill the tank with distilled water and run a short "Clean" cycle on a small area of your floor to flush the internal pump and nozzles of any chemical residue.
3. Dry the Reservoir: Remove the tank completely. Rinse it with warm water and leave it upside down on a drying rack for 24 hours. Ensure the rubber gasket at the bottom of the tank is clean and free of debris before storing.
4. Component Removal: Detach the cleaning pad and wash it thoroughly. Do not store the robot with a damp or dry pad attached, as this can trap moisture against the chassis or allow dust to migrate into the drive wheels.
5. Sensor Maintenance: Use a dry microfiber cloth to wipe the cliff sensors (the dark windows on the bottom) and the front bumper sensors. This prevents dust buildup from hardening into a film that causes "stuck" errors upon reactivation.
6. Environment Selection: Place the robot in a climate-controlled area. Avoid garages or attics where temperatures fluctuate; lithium batteries degrade rapidly in temperatures below 50°F (10°C) or above 95°F (35°C).

If That Didn't Work

• Battery Recovery: If the robot will not wake up after months of storage, the battery has likely entered a deep-discharge state. Remove the battery pack from the underside of the chassis and use a multimeter to check the voltage. If it is below the operational threshold, you will need to replace the battery with a genuine iRobot replacement part to restore functionality.
• Clogged Nozzles: If the robot powers on but doesn't spray, the nozzles are likely crystallized. Use a very fine sewing needle or a specialized nozzle cleaning pin to gently clear the spray orifice. Avoid using harsh chemicals like bleach, which can degrade the internal plastic tubing.
• Wheel Stiction: If the robot reports a "Wheel Error" after long-term storage, hair or dust may have bonded to the axle during the dormant period. Use a can of compressed air to blow out the wheel assemblies and manually rotate the wheels to ensure they move freely.
• Firmware Reset: Occasionally, long-term power loss can cause a glitch in the mapping data. If the robot behaves erratically upon return, perform a factory reset by holding the HOME button while cycling the power switch to clear the cached environment maps.

Heads Up

• Avoid Third-Party Fluids: Never store the robot with non-approved cleaning solutions in the tank; these often contain higher concentrations of surfactants that crystallize more aggressively than the official Braava solution.
• Quarterly Maintenance: If you plan to store the unit for more than 6 months, it is recommended to power it on once every 90 days and charge it to 100% to maintain the health of the lithium cells.
• Storage Packaging: If the original box is unavailable, use a breathable fabric bag rather than airtight plastic. This prevents condensation from forming inside the chassis during temperature shifts.
• Check the Contacts: Before putting the robot back into service, use a cotton swab with 90% isopropyl alcohol to clean the gold charging contacts on both the robot and the Home Base to ensure a clean electrical connection.
