Easy battery swap vs hard battery swap: Most robot vacuums are easy, but budget models are a nightmare

Most popular robot vacuums (Roomba, Roborock, Dreame, Neato, Ecovacs) let you swap the battery in about five minutes with just a screwdriver. Budget bots like the Eufy G30 or older no-names often have the battery glued or soldered in, requiring a heat gun and serious effort. Check for “user replaceable” on the product page or a teardown video before buying — if it involves a heat gun, skip it.
