Then there are the top-of-the-line Roomba s9 and self-emptying Roomba s9+, which we do not recommend. Instead of the classic puck shape, it has a D-shaped body and extra-wide brushes to improve its edge-cleaning and corner-cleaning abilities. It also has four times more raw suction than the already-strong Roomba i3 EVO, i7, or j7. That helps it consistently pick up larger debris like cat litter or yard waste better than most robots, though it still doesn’t come close to deep-cleaning dust from a rug like a traditional vacuum. We don’t like the s9 because it’s one of the clumsiest navigators we’ve tested.
Still, with regular maintenance and replacement parts such as batteries, brushes and filters, these devices can last just as long as traditional vacuums. Clean the bearings on the brush roll, caster, and side brushes every few weeks. You might need a screwdriver for this job, but many bots let you pop out the parts with no tools. Most bots come with a tool that can cut and then brush away the fuzz. These bots can use a handful of different technologies to make their maps.
Certain models are pretty good at avoiding certain obstacles, but none of them reliably avoid every kind of common floor-clutter, and some models just don’t deliver on their promises at all. The biggest problem with the RoboVac series is that they don’t last as long as Roombas do, and they can’t be fixed when they break. About a year after the 11S dyson robot vacuum was released, we started to hear from owners whose bots had already died, and the complaints have kept on coming. It’s not uncommon to hear about Eufy bots that break within 18 months, but it’s rare to hear about Roomba 600 series models failing so quickly. Pair our specialized robots together for a complete clean with less effort from you.
On its strongest suction setting , the S4 Max has enough oomph to suck up almost anything from a bare floor, but even the Balanced suction setting is fine for common debris like crumbs or pet hair. Its single brush can pick up surface-level debris from most types of carpets, but it won’t dig up hair like a dual-brush Roomba can. Also consider the Eufy RoboVac 11S, which is so quiet and nimble that it blends into the background like no other dyson robot vacuum robot . This basic, affordable bot sounds more like a desk fan than a vacuum—even if you’re home while it works, you’ll barely notice it running. It’s shorter than most bots, which lets it glide under more furniture, picking up plenty of hidden debris. The big downside is that the 11S don’t seem to be built to last for more than a couple of years on average, and we’ve heard about plenty of unrepairable breakdowns that happen even sooner.
It then repeats the main clean a second time but at a 90 degree angle to the first pass. This isn’t the end of Proscenic’s magic, however, because it’s also managed to keep the price of all this down below £500, making this a very compelling package for the price. You should also clean the sensors — usually a dry cloth will suffice, but check the manufacturer’s instructions. However, they cannot navigate stairs, and some models are more sophisticated than others. You should also keep the room bright so that the vacuum’s optical sensors can function properly.
The i7+ will detect objects only once it’s made contact with its bump sensor so could end up chewing a cable. It did navigate its way around my office chair, but it took a good amount of time to do so. Once we hear it start, we now turn chairs over onto the table to give it an easier time at cleaning. A great thing I can see from Roomba is that it offers improvements to its app over time. One new feature that has been introduced since the i7+ came out is the ability to set areas that the robot shouldn’t go into, such as your pet’s food and drink bowls.
