Robolta H4 Ultra review

The quick answer

The Robolta H4 Ultra is a cordless stick vacuum with 35 kPa suction, a 450 W BLDC motor, a detachable 2500 mAh battery and up to 60 minutes of runtime. Its auto-empty station collects dust into a 2.5 L sealed bag, and it comes with multiple brush heads for floors, sofas and cars. Choose it for hands-off dust disposal; it does not mop.

Why we like it

35 kPa listed suction from a 450 W brushless motor
An auto-empty station with a 2.5 L sealed dust bag, so the 0.25 L bin empties itself
Up to 60 minutes of runtime on a detachable 2500 mAh lithium-ion battery
Multiple brush heads for floors, sofas, crevices and cars
Lightweight and portable, with a low-noise design per Robolta

Before you buy

It is a dry vacuum, so it does not mop.
The 4 to 5 hour charge time is long, though the detachable battery helps.
Robolta lists no weight, size or decibel figures.
The page showed a Sold Out notice beside the buy button, and the store ships within India only.

Why we like the H4 Ultra for hands-off dust disposal

Cordless vacuums are quick, but emptying the small bin is the chore that makes people stop using them. The H4 Ultra docks into a station that pulls the dust into a 2.5 L sealed bag, so the 0.25 L bin never needs a trip to the dustbin. Add 35 kPa of listed suction and up to 60 minutes of runtime, and it covers a large flat in one go.

Setup and where it fits

Place the station on a flat wall-adjacent spot with room to dock the handheld unit and hang the wand and floor head. The battery is detachable, which helps with the 4 to 5 hour charge time. Robolta says it is lightweight and portable and suits car cleaning, but lists no weight or size figures, so check the handling before buying.

Everyday cleaning

The 450 W brushless motor drives the floor head, and Robolta supplies multiple brush heads for floors, sofas and crevices. The dust goes into a sealed bag in the station, which Robolta says means no manual emptying. Robolta describes the design as low noise, but gives no decibel figure.

What to know before you buy

This is a dry vacuum with no mopping. The page showed a Sold Out notice beside the buy button even though the feed showed it available, and the store ships within India only. The station’s bags are consumables, and the 60-minute runtime is Robolta’s figure, probably for a lower power mode.

Our buying advice

Buy the H4 Ultra if you want a cordless vacuum that empties itself. Robolta lists it at ₹21,999, and the partner program reports 3% off with code SEBASTIANBASSOL, which would bring it to about ₹21,339.03 if it applies; confirm the total at checkout because eligibility has not been verified. If you also want mopping, compare the R2 Pro robot vacuum.
