Roomba buying guide 2025: Are Roombas the best robot vacuums?

Roomba buying guide 2025: Are Roombas the best robot vacuums?

Note: I have not tested Roomba Max 705 Combo in person yet.

The Max 705 Combo would be the best Roomba to have on call in homes where pet messes on the floor are common. In my testing, iRobot’s PrecisionVision small obstacle avoidance is some of the most reliable on the market, especially around surprise pet waste that needs to be avoided. For pet messes (or other spills) that do need to be mopped up, the Max 705 Combo uses heated scrubbing with auto-dispensed detergent for iRobot’s most hygienic cleanup possible.

iRobot also revived the stylish wooden accents that we first saw on the 2023 Roomba Combo j9+. Anyone with a strict decorating style will have a hard time turning down this elevated look, compared to the cheap-y plastic builds of most self-emptying docks out there.

As the most powerful Roomba to date, the Max 705 Combo is kind of a shoo-in for the best Roomba for pet hair. I’m also psyched on the return of the counter-spinning parallel brush rolls underneath, which iRobot omitted on a few other recent high-end Roombas. From past experience, this dual system is incredibly effective at digging into rug fibers to pinch pet hair and long human hair (without major hair wrap around the rollers).

However, the 13,000 Pa suction power of the Roomba Max 705 Combo is only impressive compared to other Roombas — not to flagship robot vacuums from other brands. That’s significantly less powerful than the 20,000+ Pa suction power of the Roborock Saros 10 and 10R that I loved in early 2025, and is completely left in the dust by the 30,000 Pa suction power of the mighty Dreame Aqua10 Roller Ultra that recently aced my hair clump tests at home.

It’s a similar story with the Max 705 Combo’s mopping. Yes, the heated paint roller-style mop surely offers a sturdier, more sanitary scrub than Roombas with a flat mopping pad or dual spinning mopping pads. But there are several other roller mop robot vacuums out there that do the same thing, aided by more powerful vacuuming and just-as-accurate small obstacle avoidance — all at more practical price points than this Roomba. Throw in the fact that the most expensive Roomba still doesn’t have a livestream pet camera, and it’s hard for me to recommend this Roomba over the other top robot vacuums on the market.

For decades, scientists assumed that this literally continent-sized block of ice rested on an expansive and stable chunk of Earth’s crust known as a craton. A team of researchers has now complicated that picture—mapping a vast, interconnected geological structure that fans out from a troubling “tectonic deformation.” Beneath this ice sheet, thinner and more geologically recent slices of crusty lithosphere fan out into hidden valleys called “pull-apart basins.”

These basins—30 elongated wedge-shaped valleys in total—constitute an entirely new, continental-scale geological region underneath Antarctica, in fact, one which the researchers have named the East Antarctic Fan-Shaped Basin Province (EAFBP). But it’s how they likely formed that has now caught researchers’ attention.

To put it bluntly, it turns out that about 90% of the planet’s fresh water ice may not be on solid ground. Geologist John Goodge called the team’s findings “provocative” in an independent commentary on the new study, published Thursday in the journal Nature Geoscience.

“East Antarctica is typically considered from seismic tomography and geodetics to be ancient and generally stable,” according to Goodge, who studies continental tectonics with the nonprofit Planetary Science Institute. “[But] something else is going on at depth.”

Continental divides

Goodge speculates that this seemingly “coherent pull-apart system,” as presented in the new study, might help explain a variety of mysterious heat and water flows beneath this ice sheet’s surface, like that enormous subglacial lake identified in 2016 or some of the hundreds more like it.

The study’s authors, led by geophysicist Egidio Armadillo at the University of Genoa in Italy, agreed: “Because these basins underlie about half of the East Antarctic Ice Sheet, they are likely to heavily influence both ice-flow and landscape evolution,” the researchers wrote in their study, also published Thursday in Nature Geoscience.

Armadillo’s team, coordinating across Europe and the U.K., developed their new understanding of Antarctica’s hidden bedrock via an exhaustive set of sensory data. Gravitational and magnetic anomalies were mapped via low-altitude airborne surveys. Ground surface features were mapped with seismic tools, using sound waves that vibrate through the ice and ping back information about subglacial landscapes in 3D.

Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica
                The East Antarctic Ice Sheet is almost unfathomably huge. Covering about 75% of the entire frigid continent (nearly everything on its side of the Transantarctic Mountains), the sheet covers about 3.9 million square miles (10.2 million square kilometers) and extends down 1.4 miles (2.2 km), on average, before coming into contact with Earth’s surface. At its deepest, the ice plunges down over 3 miles (4.9 km).

Credit: Nature Geoscience All of this data—the fruits of “multi-national efforts to image within and below the ice sheet,” as Goodge put it—had already revealed that regions of the continent were “undergoing more rapid movement and ice-mass loss than previously recognized.” Armadillo’s team merely helped to explain why.

 The mechanism Armadillo and his colleagues proposed for the formation of these fan-shaped basins is called “distributed rotational extension.” It involves points called Euler poles around which tectonic plates pivot or rotate rather than smash into each other or pull apart. The result is a bit like decks of cards being spread out on a table, thinning out the stack of Earth’s crust as it moves. An icy situation Goodge took pains to spell out the basins’ implications for melting Antarctic ice due to climate change and the risk of rising global sea levels.

 The mere existence of these basins, he wrote, “could introduce widespread, systemic instability to the East Antarctic Ice Sheet” via thinner layers of Earth’s crust and more heat flow from below. On top of that, a series of fault-line “troughs” documented between the basins appear “tailor-made to promote outward flow of ice streams from the interior” into the world’s oceans, he said. That said, the team’s findings are unlikely to end this debate. As Goodge noted, Antarctica is “the last continental frontier of scientific exploration.” It’s still a very mysterious place, one that’s challenging to study given its inhospitable temperatures and extreme geography. Its “cryptic subglacial geology” might stay that way for a while.      #Scientists #ContinentSized #Geological #Structure #Hiding #Beneath #AntarcticaAntarctica,Geology,mapping,Plate tectonics

Ahead of this year’s World Cup, Amnesty International warned that millions of fans attending the tournament are at risk of attacks on their human rights, especially in the United States. The organization added that the tournament, which will also be held in Mexico and Canada, could take place amid severe restrictions on freedom of expression and peaceful assembly.

In a report titled “Humanity Must Win: Defending Rights, Tackling Repression at the 2026 FIFA World Cup,” Amnesty outlines a range of risks faced by fans, players, locals, and media attending the tournament in its three host countries.

In the US, where three-quarters of the World Cup matches will be played, the report finds there is a “human rights emergency” characterized by racial profiling and mass detentions by agencies such as Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP).

“This World Cup is far from the ‘medium risk’ tournament that FIFA once judged it to be,” the organization wrote. “The joy that fans hope to experience over a six-week celebration of football is overshadowed by the reality of violent arrests, mass detention,” and other abuses.

Earlier this year, then-acting ICE director Todd Lyons said ICE would be a “key part” of security during the World Cup. Since then, the extent of ICE’s role has not been fully clarified. But in May, Department of Homeland Security officials told NBC News that ICE is offering its personnel to local police departments to help with security during World Cup matches.

Amnesty International’s report indicates that in Mexico federal authorities have announced the deployment of around 100,000 security agents, including members of the army, in response to high levels of violence. According to Amnesty, this decision increases the risk for those demonstrating, including a movement of searching mothers who have planned peaceful protests in the vicinity of the Banorte Stadium (formerly Azteca Stadium) in Mexico City to demand transparency, justice, and reparations for the 133,500 disappearances registered in the country. This initiative is expected to be joined by other mobilizations during the tournament, linked to access to land, water, housing, and criticism of gentrification.

In Canada, the report notes, there are fears that the country’s housing woes will lead to unhoused populations in host cities like Toronto being displaced by World Cup activities.

When Amnesty released its report in March, the organization claimed only four of the 16 host cities had published plans for the protection of human rights during the tournament.
