iRobot Roomba 205 vs MOVA E40 Ultra

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot and MOVA sites.
2026 verdict
As a vacuum-only robot compared against a full vacuum-and-mop station, the MOVA E40 Ultra is the stronger overall pick against the iRobot Roomba 205, ahead on suction, mopping, self-emptying and warranty length.
The iRobot Roomba 205 answers with a lower price and documented dual-band Wi-Fi, something the MOVA E40 Ultra does not publish. The gap is mostly about what each one is built to do: the MOVA E40 Ultra's station washes and dries its mop and empties the bin on its own, while the iRobot Roomba 205 has no mopping hardware at all, only an internal DustCompactor that reduces how often the bin needs emptying by hand. Buyers who want mopping and a self-cleaning station should pick the MOVA E40 Ultra; anyone who only wants a compact, budget-friendly vacuum should pick the iRobot Roomba 205.

What the differences mean

Mopping

The MOVA E40 Ultra cleans with an extendable mop washed and dried by its station. The iRobot Roomba 205 has no mopping hardware at all.

Suction power

19,000 Pa on the MOVA E40 Ultra against 7,000 Pa on the iRobot Roomba 205, a large gap on carpet and stubborn debris.

Self-emptying

The MOVA E40 Ultra's station empties the bin, washes and dries the mop on its own. The iRobot Roomba 205 has no self-emptying dock, relying instead on an internal DustCompactor to reduce how often the bin needs manual emptying.

Warranty

The MOVA E40 Ultra ships with a 3 year warranty against the iRobot Roomba 205's 1 year.

Wi-Fi bands

The iRobot Roomba 205 documents both 2.4 GHz and 5 GHz Wi-Fi. The MOVA E40 Ultra does not publish whether it reaches the 5 GHz band.

Price

The iRobot Roomba 205 is the more affordable of the two, reflecting how much less hardware and automation it carries.

Which one to buy if

What owners say

Owners of both robots like how little day-to-day attention their machine needs, though for very different reasons. MOVA E40 Ultra owners describe a station that empties the bin, washes the mop pads and dries them with hot air on its own, and call the mapping fast and the pet-hair pickup strong for the price, while a recurring complaint is mop pads detaching mid-run and a cluster of side-brush or motor failures within the first year. iRobot Roomba 205 owners instead like a compact charging base with no bulky auto-empty dock at all, thanks to an internal DustCompactor that cuts how often the bin needs emptying, and praise LiDAR mapping that works accurately even in the dark, but several say a full floor still needs more than one recharge cycle, and this model has no mopping of any kind.
