Coastal Bluff Roomba

We recently repaired a Braava M6 that wasn’t spraying at all, despite the tricks we have shared on YouTube. Links here for your reference.

So we dismantled the braava and discovered that the small peristaltic water pump inside had a permanent crease in the small tubing which was causing the water to not pass (see photo). As such we had taken the pump apart and replaced with a brand new tube. After reassembling the Braava, we are pleased to share that the Braava is back to working 100 percent and available for sale.

We are pleased to add another 3D printed part to our repertoire. This is another contact holder for some i series (ADE-N1) self emptying chargers. The original contact holder can either melt (deform) from overheating (could be from a defective battery) or the contact holder can break. This causes the the roomba to not charge. We have repaired a couple of self emptying chargers successfully with this part!

We have recently prepared a roomba j9 plus for sale with only 10 hours of use (used about 3-4 times). How is this roomba different than a j7 plus roomba? They look the same. Glad you asked! It has double the suction power and double the size battery to vacuum longer before it needs to recharge. It has the same features with the rubberized brushes, washable dustbin, ability to schedule vacuuming up to 7 days a week as the j7. So essentially it’s a bit of an upgrade to the j7.

We have owned a roomba over 20 years. We have owned the same set of couches too. This photo shows the evolution of the roomba in our home. You will see the first level (500 to 900 series roombas), the roomba was able to vacuum underneath with the original black posts. All was good! But then, when we upgraded to the i-series roomba, the vacuum was too high so this meant we had to make some custom raised wooden posts. This worked for many years until iRobot adopted the LiDAR navigation which meant the roombas were even taller! This urked us, so back to our shed to find some small square wooden risers so that the roomba can once again vacuum under our couches! 🤣

Recently we were working on a Dyson V6. Upon inspection it was noted that the dustbin was not working , specifically when pushing down the red release button, the bottom of the bin was not opening. We researched replacement bins and they were between $25 to $40. We then took a closer look and realized it was missing a necessary piece and the bin itself wasn’t actually broken. Long story short, we ended up finding what we needed and 3D printed the part. After installing (see part in black in photo) everything works perfectly!

We recently worked on an old Roomba 960 that was in desperate need of some TLC. We had taken it apart completely to clean the circuit board, clean all of its components, including the cliff sensors and navigation camera, which were full of dust, recondition all of the gears, replace the tire tread, as it was quite worn, replace the front wheel, which was also worn, and replace the battery panel. See the photos below of the before and after photos. We are very pleased with the result, and what's even better is that it's vacuuming much more quietly and much more efficiently than before!

We have launched a new video to provide a step by step how to install our 3D printed contact holders on YouTube. It had taken us a while to design the contact holders but also come up with a method to make the installation easier. Here is the link:

We have been working on a 3D printed replacement contact holder for the j9 combo self filling tower. This proved to be quite difficult to design but after multiple versions we landed on a successful print! We have been testing it out in our j9 combo self emptying charger for the past month. Here we have installed it (the black part of the contact holder). Some tricky work is needed for installation as it requires mounting the white gear component which can be tricky as there is a small magnet on top and a small spring to deal with while re-inserting the metal pin at the same time. We are going to have these for sale shortly for those that would like to repair their melted charging contact!

Today we finished working on a Braava M6 (mapping robotic mop) that we got from an auction. The braava was in rough condition as the charging contacts were corroded and the lid was doing some disco lights (blue, red and white all flickering at the same time). So we nicknamed this one braava lights!

When we dismantled it, we noticed the counter weights were heavily rusted and the small water tubes were also damaged. Long story short, we replaced the charging contacts with a brand new set, replaced the counter weights, replaced the tubing and repaired the lid (dismantled the lid, repaired the small circuit board and replaced the small magnet inside the lid which was also corroded). Now this Braava is back to its new condition!

This made us wonder why this roomba with very low hours of use had so much corrosion? We figured that the inner tubings were leaking from the use of an antibacterial cleaner (can be harsh on the small tubes), causing water to leak inside.

So the lesson here is to make sure to use a proper cleaner. Rule of thumb anything that is antibacterial (Lysol) is not a good choice for these machines.

See the photos below for the before and after!

We are donating a roomba, fully serviced by ourselves in support of the fundraising efforts of the local air cadet squadron! Here is a photo of the roomba that is being raffled off tomorrow amongst other great prizes! We think the winner will be ecstatic!
