HIXZAP X1 PRO review: 7,200 Pa of grip, a 25-minute backup battery and a remote that does everything without an app

HIXZAP X1 PRO at a glance

First impressions of the HIXZAP X1 PRO

The HIXZAP X1 PRO is a black, rounded robot with two spinning pads underneath, and it feels more substantial in the hand than the standard X1.

The box is generous: the robot, a remote, a safety cable, a power adapter and cord, a water bottle and a stack of 20 reusable microfiber pads.

That pad count tells you HIXZAP understands dual-pad robots. Pads get dirty fast, and you want plenty to rotate.

I started on the inside of our garden-facing sliding door. Tank filled, pads damp and fitted, cable anchored, plugged in.

It locked onto the glass with a strong pull, then worked from top to bottom in an S-shaped path, misting from the left as it moved left and from the right as it moved right.

When it finished, it stopped and beeped. The glass was clearly clean, with the familiar curved patches in each corner.

The real test came a week later, on the outside of an upstairs window. The X1 PRO’s grip and backup battery made that feel very different from the standard X1.

By the end of the month, it had become my go-to for high glass.

The other early impression was how calm the controls felt. A handful of buttons on the remote covered everything I needed, and I never once went looking for a manual after the first day.

That simplicity, combined with the stronger grip, is what separates it from the standard X1 in daily use.

What the HIXZAP X1 PRO actually is

The X1 PRO is HIXZAP’s step-up dual-pad✕Dual spinning padsTwo round microfiber pads that rotate against the glass and pull the robot along. They scrub well but leave small curved corners uncleaned. window robot.

HIXZAP X1 PRO design and setup

The design is the same family as the X1: a rounded body over two round pads.

Spinning pads scrub actively, which helps on fingerprints and light grease. Their shape means they cannot fill a square corner.

HIXZAP lists a minimum glass size of about 12 by 12 inches, so very small windows are out.

Before each clean

Our tip: Set spray to light for inside glass and strong for outside glass. Too much water on clean glass is the main cause of streaks.

How the dual pads clean

The X1 PRO has no tracks. Its two pads spin in opposite directions, and the friction moves the robot as they scrub.

The effect is like rubbing a window in small circles rather than dragging a cloth across it.

That is great for smudges and the oily film on kitchen and patio glass, which tends to smear under a flat pad.

It also means the pads get dirty quickly and show it as swirls, which is why the 20 included pads are so useful.

Suction and safety on high windows

This is where the PRO earns its name.

At up to 7,200 Pa, it grips glass from 3 mm thick and up, and it felt planted on every window I tried, including the outside of upstairs panes.

HIXZAP calls its approach 3-layer protection.

If the power goes

If the power is cut, the backup battery✕Backup batteryA small battery inside the robot that keeps the suction fan running if the power is cut, so the robot stays stuck to the glass while it beeps for help. keeps the fan running for about 25 minutes while the robot alerts you.

I tested it by pulling the plug on an inside window. It stayed put and beeped until I reconnected it.

That is the feature that makes second- and third-floor windows a reasonable job rather than a gamble.

Testing the backup battery and alarms

Safety claims are easy to print on a box, so I tested the X1 PRO’s backup myself, on an inside window with the safety cable✕Safety tetherA strong cord that clips the robot to something solid indoors. If the robot ever lets go of the glass, the tether catches it before it can fall. attached.

Mid-clean, I pulled the power plug from the wall.

The robot stopped moving, the fan kept running and it began beeping loudly. It stayed firmly on the glass.

I left it for ten minutes to be sure. It was still attached and still beeping when I came back.

I also slid a finger under one edge to break the seal slightly. The suction✕Suction (Pa)How hard the fan pulls the robot against the glass, measured in pascals. More pascals means a firmer grip, which matters most on outside windows and big panes. monitoring picked it up and sounded an alert straight away.

I would not test this on an upstairs window, and you should not either. But it gave me real confidence when I did clean high glass.

Dual ultrasonic spray and the 85 ml tank

Two ultrasonic nozzles mist the glass, one on each side. The left one sprays when the robot moves left, the right one when it moves right.

That keeps the glass evenly damp just ahead of the pads, which helps them dissolve dirt and stains rather than smearing them.

The remote lets you choose light or strong spray. Light was right for inside glass; strong helped on dusty outside panes.

The 85 ml tank is visible from outside the robot and lasted my whole ground floor on one fill.

Our tip: Use filtered or distilled water in hard-water areas. Ultrasonic nozzles stay clearer, and you avoid faint mineral spots on dark glass.

What to put in the tank

The X1 PRO sprays whatever is in its tank, which keeps running costs low.

Over the month I compared hard tap water, filtered water and filtered water with a few drops of a non-foaming glass cleaner.

Filtered water gave noticeably fewer mineral spots on dark glass than our hard tap water.

A tiny dose of non-foaming cleaner helped on the greasy kitchen window, but made little difference elsewhere.

Avoid anything that foams, which can block ultrasonic nozzles and leave a film.

The remote: everything without an app

The X1 PRO has no app and needs no Wi-Fi. Everything happens on a small remote.

I liked that more than I expected. No account, no updates, no phone hunting.

Manual steering was handy for driving the robot to one nose print in the middle of a big door, then switching to spot mode.

If you love app control and schedules, you will miss them. If you prefer a simple remote, this is a plus.

S-shaped path and spot cleaning

Placed on the glass and started, the X1 PRO maps an S-shaped route✕Path planningThe route the robot follows across the glass. An S-shaped or Z-shaped path covers the window in overlapping stripes so nothing is missed. from top to bottom.

It works in overlapping stripes, which kept it from missing bands of glass or repeating sections unnecessarily.

When it finishes, it stops and beeps, so you know it is time to lift it off.

Spot mode tackles a stubborn mark with focused back-and-forth scrubbing.

How well the HIXZAP X1 PRO cleans

Everyday dirt came off well. Dust, pollen and fingerprints cleared in one pass, and the scrubbing pads handled smudges nicely.

On dirtier outside glass, one pass made a big difference and a second with fresh pads finished the job.

Edges and corners

Along straight frames, the X1 PRO gets reasonably close. It follows the edge and turns cleanly.

In corners, the round pads cannot reach, leaving four small curved patches on every rectangular pane.

My cleaning ratings by part of the window, out of 10.

A damp cloth fixes the corners in seconds, but if you want a robot that finishes the whole window, look for a square design.

Our tip: Wipe corners right after the robot stops, while the glass is still slightly damp. Dry corners take longer to clean and are easier to streak.

Outside and upstairs windows

Outside glass is where the X1 PRO shines among dual-pad robots.

With the cable anchored to a radiator pipe and the cord run through the window, I cleaned the outside of two upstairs bedroom windows that had not been touched in years.

The robot held firm, worked its S-path down the glass and beeped when done. I lifted it back in with two hands.

Clean outside glass in shade or on an overcast day. Direct sun dries the mist too quickly and leaves faint marks.

My routine for high windows

With this routine, I never had a slip or a scare in four weeks.

Balcony glass and big sliders

Large balcony panes and sliding doors are where the X1 PRO is most at home.

The S-shaped route covers a big pane in long, even stripes, and the 85 ml tank easily lasts several large doors.

On a friend’s apartment balcony, we cleaned both sides of the glass in about half an hour, with the cable tied to a sturdy railing post.

Strong suction mattered here. On a breezy day, it stayed planted without a wobble.

Our tip: On balconies, tie the cable to a railing post or other fixed structure, never to patio furniture that could slide.

Power and cord reach

The X1 PRO runs on mains power. The battery is only for emergencies.

That means unlimited cleaning time while plugged in, but you need an outlet within cord reach of every window.

For outside glass, I ran the cord through a door or window, and for windows far from sockets I used an extension cord.

Our tip: Keep the cord and safety cable apart. When they twist together, they can drag the robot off its path.

Kitchen windows, mirrors and shower glass

Indoors, the X1 PRO’s scrubbing pads were most useful on the grimy glass that flat-pad robots tend to smear.

Kitchen window

Our kitchen window gets a thin film of cooking grease plus water splashes from the sink.

With light spray and fresh pads, one full run cleared most of it, and a spot pass finished the area nearest the stove.

Bathroom mirror

The mirror came out bright and streak-free across the middle. The four curved corners needed a wipe, and on a mirror you notice them more than on a window.

Shower glass

Soap film improved over two passes. Limescale needed a descaler first, as it does with every robot.

Our tip: Let steam clear before cleaning bathroom glass. On a fogged mirror, the pads slip and the robot has to work harder for a worse result.

Which windows and surfaces it suits

HIXZAP lists windows, mirrors, tiles and any smooth glass of at least about 12 by 12 inches.

What using it is really like

Setup took about two minutes, and the remote made adjustments quick.

The noise is a steady blend of fan and spinning pads, clearly audible in the same room.

At the end, I lifted it off, wiped the corners and dropped the used pads into a bowl to rinse later.

My hands-on time for a typical session.

The deck door, a weekly job for the X1 PRO.

A whole-house cleaning day

I used the X1 PRO for a full cleaning day: inside glass upstairs, then downstairs, then outside panes in the afternoon.

I soaked eight pairs of pads the night before, set spray to light indoors and strong outdoors, and swapped pads every two windows.

About 40 minutes of my own time covered the whole house. By hand, upstairs outside glass never got done at all.

Robot versus cleaning by hand

How to get the best results

• Match spray strength to the glass: light inside, strong outside.
• Rotate pads every two windows.
• Center both pads so it tracks straight.
• Use filtered or distilled water in hard-water areas.
• Clean outside glass in shade.
• Wipe corners while the glass is still damp.
• Keep the cord and cable apart.

Pad care with 20 pads

Twenty pads in the box is a statement: HIXZAP expects you to swap them often, and you should.

With a dual-pad robot, pads do the scrubbing and the moving, so any dirt on them shows straight away as swirl marks.

My routine was to soak several pairs before a session, wring them until just damp, and lay them out on a towel.

I swapped pairs every two windows, and immediately after any very dirty outside pane.

Afterward, I rinsed them together and hung them to dry. Every few weeks I machine-washed them on a gentle cycle without fabric softener.

Cleaning and maintaining it

Supplies and long-term ownership

Running costs are low. The tank takes water, and 20 washable pads will last a long time.

There is no storage case, so I kept the robot, remote, adapter, cable and pads together in a lidded tub.

After four weeks of regular use, inside and out, suction and the backup battery worked exactly as on day one.

Noise, pets and family life

The fan and spinning pads make a steady, busy sound. It is fine in the next room, noticeable in the same one.

Our cat was fascinated by the spinning pads for a day and then lost interest.

With children and pets around, keep the cord and cable out of walkways, and remember that outside sessions involve an open window.

Which homes it suits best

If your problem windows are high up and you want an affordable, app-free robot you can trust, the X1 PRO is a strong choice.

Who will enjoy it most

Owners of multi-story homes who have been putting off upstairs windows will get the most out of it.

People who want an app, schedules or perfectly finished corners will be happier with a square, app-controlled robot.

Living with it: week one to week four

Week one: inside glass and getting used to the remote.

Week two: upstairs outside windows, with the cable anchored and the backup tested.

Week three: a full house cleaning day and a proper pad rotation routine.

Week four: quick weekly runs on the doors and spot cleaning for prints.

My overall satisfaction each week, out of 10.

What surprised me, good and bad

The best surprise was how much I liked the remote. No app turned out to be a feature, not a gap.

The second was confidence on high glass. The grip and backup made upstairs windows routine.

The less welcome surprises were the corners, which I knew about but still noticed, and the need to plan around outlets.

How each detail compared with my expectations before testing.

Common mistakes to avoid

The HIXZAP X1 PRO is easy to use, but these habits hold it back.

What I would change

A square-corner solution and a longer cord would make it close to complete.

Is it a good first window robot?

If your first reason for buying a window robot is high or outside glass, the X1 PRO is a sensible first robot.

It is simple to operate with the remote, has meaningful safety features and comes with everything you need, including plenty of pads.

Expect a learning curve on spray strength and pad swaps, and expect to wipe the corners.

If your windows are all at ground level and easy to reach, the standard X1 may be all you need.

Is the HIXZAP X1 PRO worth the money?

For high and outside windows on a budget, yes.

You get strong suction, a real backup battery, live suction alerts, a capable remote and 20 pads, which is a lot of robot for the money.

You give up corner coverage and the polish of premium robots with stations and apps.

Ask yourself three questions. Are your problem windows high up? Do you prefer a remote to an app? And can you live with wiping the corners?

If so, the X1 PRO is easy to recommend.

Where your money goes

Compared with the X1, you pay for more suction, the backup battery, live suction alerts, a better remote and more pads.

If you clean upstairs or outside glass, the backup battery alone justifies the step up.

How it compares with the HIXZAP X1

From manufacturer data and my own testing.

How I tested and scored the HIXZAP X1 PRO

For four weeks, I used the HIXZAP X1 PRO on sliding doors, large windows, balcony glass and the outside of upstairs windows.

I tested both spray strengths, spot cleaning and manual steering, ran a whole-house cleaning day and checked the backup battery by cutting power.

I rotated pads on a schedule, tracked corner coverage and timed my hands-on work.

I then checked my notes against HIXZAP’s published specifications.

• Cleaning (7.9): dust, fingerprints, pollen, grease film and outside grime on windows, doors and balcony glass.
• Edge coverage (7.0): how close the dual pads reach to frames and how much is left in the corners.
• Ease of use (8.1): setup, the remote, spray strength, spot cleaning, pad swaps and storage.
• Safety (8.3): 7,200 Pa suction, the 25-minute backup, suction alarms and the safety cable.

The overall score of 7.8 is an editorial rating that reflects those four areas.
