# Bissell robot vacuum won't charge: causes and fixes

A Bissell robot vacuum that won't charge usually has its power switch off, a battery not seated properly, dirty charging contacts, or a dock without enough clear space. Here are the fixes from Bissell's SpinWave, EV675, SmartClean and DigiPro guides and how to pages.

## Short answer

Check the power switch first: Bissell says the SmartClean and DigiPro will not charge unless the switch is on. Turn the robot off, wipe the charging contacts on the robot and dock with a cloth, and reseat the battery so its terminals match the marks. Give it a 4 to 5 hour first charge, plugged straight into the robot on SmartClean and DigiPro models. If it still will not charge, the adapter or battery is likely failing.

| What you see | Likely cause | Fix |
|---|---|---|
| No lights, will not charge | Power switch off | Turn the power switch on. Bissell says the robot will not charge with it off. |
| E6 on the display | Battery not seated, or switch off | Turn it off, open the battery cover, reseat the battery with terminals matching the marks, switch on. |
| Dead out of the box | First charge not done | Charge 4 to 5 hours. On SmartClean and DigiPro, plug the adapter straight into the robot. |
| Docked but no charging light | Dirty charging contacts | With the robot off, wipe the contacts on the robot and dock with a cloth. |
| Robot will not back into the dock | Not enough space around the dock | SmartClean: 40 inches clear one side, 12 inches the other, nothing in front. SpinWave: 1 meter each side. |
| Dock has no power | Adapter loose | Plug the adapter firmly into the wall and the side port of the dock. |
| Lo on the display | Battery low | Return it to the dock or plug the adapter into the charge port. |
| EV675 flashing red | Battery low, or stuck, or cliff sensors | Charge it, then clean the cliff sensors if it stays red. |
| Light pulses slowly on the base | Charging normally | SpinWave shows slow white pulses and EV675 breathing blue. EV675 light goes off when full. |
| Still no charge from a good outlet | Owner fix: adapter or battery failing | Owner fix: test the adapter output with a multimeter. No voltage means a new adapter; voltage means a new battery. |
| Charges but runs are short | Worn battery | Replace the battery. Bissell sells genuine replacement batteries for its robots. |

## 1. Check the power switch and battery

Bissell's robots have a separate power switch on the side or underside, and it catches a lot of owners out. Bissell's DigiPro guide says plainly that the machine will not charge unless the switch is on. The SmartClean shows E6 when the switch is off or the battery is not installed correctly.

To reseat the battery on a SmartClean or DigiPro, turn the switch off, turn the robot over on a flat surface, press the two circles on the battery cover and slide it open. Match the plus and minus terminals to the marks in the compartment, close the cover and switch on. On an EV675, the battery cover is held by two Phillips screws.

## 2. Give it a proper first charge

Bissell says the first charge takes 4 to 5 hours on the SpinWave, SmartClean, DigiPro and EV675. For the SmartClean and DigiPro, Bissell says to plug the adapter directly into the robot's charging port for that first charge, not the dock, so the battery gets a full charge.

Learn what normal charging looks like. A SmartClean shows 99 when full. A SpinWave on its base shows slow white pulses. An EV675 shows a breathing blue light while charging, and the light turns off when it is full.

## 3. Clean the contacts and fix the dock spot

With the robot off, wipe the charging contact points on the robot and on the dock with a cloth. Then check where the dock sits:

- SpinWave: on a hard surface with at least 1 meter clear on each side and nothing in front, adapter plugged into the side port of the base.

- SmartClean: at least 40 inches clear on one side, 12 inches on the other, and nothing in front.

- EV675: away from obstacles, with the contacts on the robot and dock touching.

- To test docking on a SmartClean, turn it on and press the center power button until 00 and a dock icon show. It should back into the dock.

## 4. Replace the battery or the adapter

If the robot charges but only runs for a short time, the battery is worn. Bissell sells genuine replacement batteries, and it publishes a battery replacement video for the SpinWave. Batteries in older SmartClean and EV675 robots are removable using the cover clips or screws described above.

If it will not charge at all from a known good outlet, owners on iFixit suggest testing the power adapter with a multimeter. No voltage at the plug means the adapter needs replacing; good voltage points to the battery. They also suggest checking the battery terminals for corrosion.

## 5. When to contact Bissell, or replace the robot

Contact Bissell through support.bissell.com if a new battery and adapter do not fix it, or if the robot is under warranty. Bissell lists a one year limited warranty for the EV675 on its product page; check the warranty guide on your model's page before you buy parts.

A battery or adapter is a cheap fix on any Bissell robot. If an older SmartClean, DigiPro or EV675 needs a new charging board or main board, a new robot vacuum is usually the better spend.

## Questions people ask

### Why won't my Bissell robot vacuum charge?

Most often the power switch is off, the battery is not seated, or the charging contacts are dirty. Bissell says it will not charge with the switch off.

### How long does a Bissell robot take to charge?

Bissell says the first charge takes 4 to 5 hours. The SpinWave product page lists a 4 hour charge time.

### What does E6 mean on a Bissell robot?

The battery is installed incorrectly or the power switch is off. Reseat the battery with the terminals matching and switch it on.

### How do I know my Bissell SpinWave is charging?

On the base, the status light pulses slowly in white. A ring light may breathe for 30 seconds and then turn off.

### Can I replace the battery in a Bissell robot vacuum?

Yes. Bissell sells replacement batteries and has a battery replacement video for the SpinWave. The EV675 battery cover has two screws.
