iRobot Roomba Max 705 vs MOVA E40 Ultra

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot and MOVA sites.
2026 verdict
In the crowded field of all-in-one self-emptying robot vacuums, the MOVA E40 Ultra edges out the iRobot Roomba Max 705 by adding what the Roomba cannot do at all: mopping.
MOVA E40 Ultra
Winner
MOVA E40 Ultra
Buy on Amazon GermanyCheck price
It rates higher with owners, carries a three-year warranty against one year, runs 260 minutes per charge against 120, pulls 19,000Pa of suction against 13,000Pa, and its station washes and hot-air dries its own mop pads. The iRobot Roomba Max 705 keeps a real advantage in smart home reach, documenting Apple HomeKit, Samsung SmartThings, Home Assistant and Matter alongside Google Home and Alexa, a wider list than the MOVA covers. Both self-empty at their docks. Choose the MOVA E40 Ultra if you want vacuuming and mopping handled together, and the iRobot Roomba Max 705 if the broadest smart-home ecosystem support matters more than mopping.

What the differences mean

Mopping

The MOVA E40 Ultra mops with an extendable pad reaching into corners, and its station washes and hot-air dries the pads automatically. The iRobot Roomba Max 705 has no mopping function at all; it is a vacuum-only robot.

Suction power

19,000Pa against 13,000Pa favors the MOVA E40 Ultra, a difference that shows up most on thicker carpet and heavier pet shedding.

Battery life

The MOVA E40 Ultra is rated for about 260 minutes per charge, more than double the 120 minutes iRobot rates the Roomba Max 705 for.

Warranty

MOVA backs the E40 Ultra with a three-year warranty, two years longer than the one year iRobot gives the Roomba Max 705.

Smart home platforms

The iRobot Roomba Max 705 documents Google Home, Alexa, Apple HomeKit, Samsung SmartThings, Home Assistant and Matter, all six. The MOVA E40 Ultra covers Google Home, Alexa and Home Assistant, with no Apple Home, SmartThings or Matter support.

Cliff detection

iRobot documents cliff detection for the Roomba Max 705. MOVA does not confirm whether the E40 Ultra detects drops, which is worth checking if your home has stairs it needs to avoid.

What owners say

Owners of both machines say the auto-empty dock is what sold them, but they are solving different problems. iRobot Roomba Max 705 owners upgrading from older Roombas praise faster, more accurate LiDAR mapping and strong pickup on carpet and pet hair, with WiFi setup failing on router passwords with special characters as the main complaint. MOVA E40 Ultra owners describe a home mapped in about fifteen minutes, quiet running, and a station that empties, washes and refills without being asked, but the recurring complaint is mop pads detaching mid-run, alongside scattered reports of side-brush or motor failures within the first year that support has generally replaced.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
