Every robot we weighed, on carpet
More detail behind the picks
The Saros 20's brushes never needed cutting free in one home that ran it daily for 90 days with a shedding dog. That same home tester found the first map drew his rugs as circles, which broke the automatic pad drop until he traced the rugs by hand, a twenty-minute fix. The L60 Ultra PE also avoided 21 of 24 obstacles at Vacuum Wars, and the Qrevo Curv 2 Flow recovered 87% of buried sand in medium pile there. One more suction example: the Roborock Q7 M5+ claims 10,000 Pa and measured 2.24 kPa at the brush, several times the Saros 20, yet cleaned buried sand only as well as Vacuum Wars' average.
Skip these, and also considered
Who tested what, and how
Vacuum Wars buys its robots; its carpet figure is sand worked into medium-pile carpet and cleaned at maximum power, with the bin weighed, and its pet-hair figure comes from hair flattened into carpet and run twice. The Hook Up, unsponsored, in April 2026, spread a weighed mix of flour, salt, flax and rice on high-pile carpet and ran two vacuum-only passes at top suction; its auto-captions garble the Saros 20's name, so that robot is identified by its stated 36,000 Pa. RTINGS buys retail units, scores a sand, rice and cereal mix on low and high pile by eye, presses synthetic pet hair into low pile with a weighted roller, and runs a loose tasseled rug in its adaptability room. Its X60 review ran on firmware 4.3.9_1495 (July 2026), and its Q7 results come from the dockless Q7 M5, which RTINGS says is the same robot as the M5+. Several climbing robots top out at exactly 1.5 in (38 mm) at RTINGS, which looks like the top of its threshold range rather than the robots' limit. Consumer Reports tests robots on medium pile; its carpet list featuring the Roomba Max 705 dates from August 2025.
Where sources disagree
On the eufy Omni S2, The Hook Up's 78.8% on deep pile and Vacuum Wars' 87% in medium pile sit against RTINGS' "poor" on both piles. Method explains it: loose debris is lifted and pressed-in material is not. Vacuum Chef's deep coffee-grounds carpet test also scored the S2 below its predecessor. That unit came from eufy in late November 2025, ahead of the hardware upgrade eufy made before the S2's US launch, so the result may describe older hardware than the current S2. Why the brush behaves that way is still open.
The Dreame X60 has one weak lab result, CNET's sand on midpile, run by CNET's own method. RTINGS' tester said in comments he wouldn't recommend it "right now" because of software bugs, and one owner describes phantom walls appearing after a few days; firmware has also moved its carpet results upward at one lab. The Hook Up found 7.1 g caked in the bin after auto-empty, while another reviewer found only crumbs, and RTINGS' tester found the highest auto-empty suction setting helps a lot.
On the Roborock Saros 20, Tom's Guide measured 70% of pet hair on its own rug against 90% on hardwood, with an unclear dose, and a one-week cat owner on very short, dense carpet saw hair left behind. That may be a weak spot lab carpets don't reproduce; it is unconfirmed.
Dreame says the L60 Ultra PE removes its mops on long-pile rugs, while Vacuum Wars records that it doesn't drop pads at the dock. That stays open.
Where RTINGS' threshold figure sits below Vacuum Wars' and The Hook Up's on the same robot, RTINGS' test ceiling explains it, so the table gives the tallest single step any lab recorded.
