Eureka Lists 6 Robots; Only the 3 J15 Docks Wash Mops

Eureka’s US store listed six robot vacuums on 29 October 2026: the J15 Max Ultra, J15 Ultra, J15 Evo Ultra, E20 Evo Plus, E20 Plus and E10s. The letter is the split: the three J15s have a dock that washes and dries the mop pads, and the three E-series robots have a bagless dock that only empties dust.

Prices below are each product page’s “Regular price” that day. Specs are Eureka’s, from its compare page and each product page; where the two disagree, we say so.

The 6 Eureka robots, by list price

Robot	List, 29 Oct	Halloween discount at checkout	Suction (Pa)	Battery (mAh)	Obstacle sensing (Eureka)
E10s	$399.99 (sold out)	—	4,000	5,200	Right-side PSD
E20 Evo Plus	$399.99	$210	10,000	5,200	Right-side PSD
E20 Plus	$449.99	$250	8,000	5,200	Dual-line laser + right-side PSD
J15 Evo Ultra	$599.99	$300	22,000	5,200	Single-line laser
J15 Ultra	$699.99	—	19,000	5,200	Single-line laser + RGB camera
J15 Max Ultra	$1,199.99	$500	22,000 (21,600 in its Product Specs)	6,400	Single-line laser + RGB camera + infrared vision

All from Eureka’s US pages on 29 October 2026. A dash means the product page showed no checkout discount that day. The E20 Plus is also sold in white as a separate listing at the same price. PSD is a position-sensing distance sensor.

Suction does not climb with price. The two robots at 22,000 Pa sit $600 apart in list price, and the E10s lists 4,000 Pa at the same list price as a robot rated at 10,000 Pa. All six quote pascals, so the column compares like with like within Eureka; the J15 Max Ultra page notes its figure comes from Eureka Lab tests.

The dock and the mop

Robot	Dock	Water tanks, clean / dirty (L)	Mop wash	Mop drying	Mop lift on carpet (mm)
E10s	Bagless, empties dust	—	—	—	10
E20 Evo Plus	Bagless, empties dust	—	—	—	10
E20 Plus	Bagless, empties dust	—	—	—	10
J15 Evo Ultra	Empties dust (bag or bagless: see below)	4 / 3.4	80 °C water	55 °C air	12
J15 Ultra	Bagged, 3 L	4 / 3.4	75 °C water	55 °C air	12
J15 Max Ultra	Bagged, 3 L	4 / 3.4	Cold water	55 °C air	12

Water, wash, drying and lift figures are from Eureka’s compare page; the J15 Evo Ultra and E20 Plus pages repeat their lift figures, and the J15 Ultra page repeats its 75° wash. A dash means Eureka lists none.

The E-series robots mop, but their docks hold no water, so the pad is not washed at the dock. A J15 dock washes the pads and dries them with hot air, and all three J15s extend the mop toward edges, which Eureka calls ScrubExtend.

The J15 Max Ultra lists a cold-water wash where the cheaper J15 Evo Ultra and J15 Ultra list 80 °C and 75 °C. What it adds instead, by Eureka’s pages: a 6,400 mAh battery and up to 360 minutes of runtime, a scraper that clears the dock’s wash tray, a roller brush that lifts on wet spills, and 40 mm obstacle crossing (stated as 4 cm) against 20 mm for the other five.

The J15 Evo Ultra page contradicts itself on the dust: its specs and FAQ call the dock bagless with a 4 L dust cup, while its feature copy describes a 3 L dust bag lasting up to 75 days and its box list includes a pre-installed bag. The compare page gives 3 L. If bags matter to you, ask Eureka before you buy.

How drag pads, spinning pads, rollers and tracks differ across makers is in our guide to robot mop types; here the point is which Eureka has a dock that cleans the pad.

Who each one suits, by the specs

• Vacuuming with a light mop, and no mop washing: the E10s, E20 Plus or E20 Evo Plus. Of these, Eureka lists the most suction on the E20 Evo Plus and the only laser obstacle sensor on the E20 Plus (affiliate link to Amazon, opens in a new tab).
• A dock that washes in hot water and dries the pads: the J15 Evo Ultra or J15 Ultra; the J15 Ultra (affiliate link to Amazon, opens in a new tab) adds an RGB camera, the Evo Ultra lists more suction.
• The larger battery, the self-cleaning wash tray and the most obstacle sensors: the J15 Max Ultra (affiliate link to Amazon, opens in a new tab), with a cold-water wash.

Narwal’s range is sorted the same way as this page. Eureka is not among the robots in our review roundup, and what each price band buys across Roborock, iRobot and eufy is in robot vacuum prices, feature by feature.

Questions people ask

What is the difference between the Eureka J15 Ultra, J15 Evo Ultra and J15 Max Ultra?

All three have a dock that washes and dries the mop pads. On Eureka’s compare page the Evo Ultra lists 22,000 Pa and an 80 °C wash, the J15 Ultra 19,000 Pa, a 75 °C wash and an RGB camera, and the Max Ultra 22,000 Pa, a cold-water wash, a larger battery and the most obstacle sensors.

Which Eureka robot vacuum has the most suction?

The J15 Evo Ultra and J15 Max Ultra, both 22,000 Pa on Eureka’s compare page. The Max Ultra’s own Product Specs give 21,600 Pa, so Eureka’s pages disagree on that one.

Do Eureka E20 robots wash the mop?

Not in the dock, on Eureka’s figures. The E20 Plus and E20 Evo Plus docks are bagless dust stations, and Eureka’s compare page lists no clean or dirty water tank for them. Both robots lift the mop 10 mm on carpet.

What is the difference between the Eureka E20 Plus and E20 Evo Plus?

Eureka lists 10,000 Pa for the E20 Evo Plus against 8,000 Pa for the E20 Plus. The E20 Plus names a dual-line laser for obstacles; the Evo Plus names only a side sensor. Both have a bagless self-emptying dock and a 10 mm mop lift.

Is the Eureka J15 Evo Ultra bagless?

Eureka’s page says both. Its specs and FAQ call the dock bagless with a 4 L dust cup, while its feature copy describes a 3 L dust bag lasting 75 days and its box list includes a pre-installed dust bag.
