Introduction

In iLife (Chuwi) V7, V7S robots 4 beeps mean that the brush is not rotating and vacuum requires clean up. If you already did the normal clean up (clean main brush, dust bin, side brush, center wheel) and your robot vacuum still encounters the same issue of suddenly stopping backing up and beeping 4 times it means that this time you need to clean the main brush motor. Something stops it from spinning.

In this manual you'll find tearing down and fixing robot vacuum iLife V7S. The issue fixed is continuous stopping with 4 beeps even with new brushes and vacuum cleaned.

This teardown is not a repair guide. To repair your Chuwi iLife V7 and V7S, use our service manual.

Now you should see something like this Unplug the power wire from the motor and put it aside, memorize how it was installed One all other parts were removed from the way you can put your vacuum on the side of the table or on your knees and start pulling out the motor tray from the bottom of the unit
  • Now you should see something like this

  • Unplug the power wire from the motor and put it aside, memorize how it was installed

  • One all other parts were removed from the way you can put your vacuum on the side of the table or on your knees and start pulling out the motor tray from the bottom of the unit

  • Use your fingers to push the transparent flap through the opening while pulling the tray out

  • With the motor tray removed from the unit unscrew three white screws from the side of the tray to open the main gear and the belt, remove all dust and hairs and unscrew 2 small screws holding the motor

  • With the motor removed use tweezers, needle or anything that works to remove hairs and dust from behind the motor gear. Once everything is cleaned and tidy apply some WD40 to the bottom of plastic gear and perhaps put a drop behind the motor gear. DO NOT SPRAY it on the motor or inside the motor. This could make a fire hazard!
