"vacuum is not sucking up dirt from the floor"に関する回答Sometimes the area between the brush and cannister (maybe a hose in your case) become clogged with hair and stuff. Figure out how to open it up.
"Why is my bluetooth speaker randomly turning off? (JBL Xtreme)"に関する回答I contacted the tech support and they were of little help, aside from telling me the device was optimized for a mobile device. Here is what I have figured out: (1) Make sure the driver is up to date (1) when you want to use it with your computer, get the video or whatever you want to listen to running then connect with the speaker. If you stop and start another video, you probably want to disconnect and reconnect pairing with the speaker or else it may crash. *if you loose the connection with the speaker and the bluetooth icon disappears then you have to restart your computer and it should reappear.
