AI found three parts to save my five-year-old Roomba

Our Roomba j7+ is about five years old, which apparently makes it an elder statesman in robot-vacuum years.

It still cleaned well. The battery, drive-wheel tires, and little front caster were worn. I already handled brushes and filters. I wanted to know what else genuinely needed replacement before I opened it up and started practicing unnecessary robotic medicine.

The exact model mattered. This was the original vacuum-only j7+ with the self-emptying base, not the later Combo. AI recommended a small refurbishment instead of replacing every module because the machine had reached the horrifying age of five.

The wheel question was especially useful. If the motors still sounded normal and moved with equal resistance, I didn't need two complete wheel assemblies. I needed new rubber tires. The rest became a clean-and-inspect list: cleaning head, side-brush motor, wheel wells, sensors, charging contacts, camera lens, bumper, and the Clean Base evacuation path.

Then I asked for the three parts on Amazon. AI found a battery that explicitly listed the original j7+, a genuine iRobot caster with the correct part number, and replacement tires. It checked recent owner reviews from people using the same robot. One supported the battery in a nearly five-year-old j7+. Another said the chosen tires gripped the dock correctly.

“Compatible” on a listing is not the same as “works in the machine sitting in my house.”

I ordered all three. The parts that still work will get cleaned and left alone. The Roomba gets a battery, a caster, and new tires, then returns to its tiny vacuum job with dignity.
