iRobot Roomba 770: Why won't my roomba 780 stay in its dock?

Tue, 22 Oct 2019 04:27:22 -0700

My roomba 780 will try to dock itself but can't line up with the points. I have to stick a coaster of something under the back of it to dock and charge. And I have tried cleaning all the points, that is not the problem. It won't dock at the right angle.

iRobot Roomba 770: The Roomba barely moves then stopd

Wed, 20 Jun 2018 11:00:39 -0700

The Roomba comes off the charger moves a few inches - stops- beeps and sometimes the red triangle flashes. I have checked the battery and it is holding the charge. I have moved the Roomba to difderent locations and pressed start and the same thing happens. I have cleaned IR sensors. What is going on?

Also: Where can I get a copy of the service manual for Roomba 700 Series vacuum? I don’t need the owners manual.

iRobot Roomba 770: iRoomba 775 vacuum motor always on (?!)

Tue, 14 Dec 2021 13:27:01 -0700

Hi,

My Roomba 775 has started acting weird. With a full battery (measured ~15 V) even when the Roomba is switched off, as soon as I put in the dust bin, the vacuum motor will engage and remain running (?!).

Likewise, once I switch it on, the vacuum motor remains engaged. The Roomba won’t move if I press on “Clean”. Zero action, other than switching on the lights and keeping the vacuum motor running without need.

I’ve tried the reset trick (press and holding Clean for 10 seconds), but this did not help.

Any hints on where to look? I’ve googled up and down without success :(

Thanks in advance!

iRobot Roomba 770: Stripped screw of battery compartment

Sat, 02 Sep 2023 07:41:35 -0700

The battery compartment of the Roomba 770 has two screws. One of the two screws is completely stripped.

There is no remainder of the original drive slots. I tried putting some rubber sheet between the screw head and the screwdriver tip to increase traction, no result.

I want to access the battery compartment to put in the new battery I bought, as the screw is stripped I have no means of opening it. Everything else is intact. Can I somehow work my way around this? How can I remove the stripped screw? If necessary to buy addtional tools: I do not have much budget for this project.

Tools I own:

BLACK+DECKER Li2000 3.6-Volt 3 Position Rechargeable Screwdriver

Black & Decker 71-081 Double Ended Screwdriving Bit Set, 10-Piece
