How loud are Sun Joe tools? Sun Joe lists 85 to 113 dB

What do Sun Joe's decibel numbers measure?

Single values in dB, with no distance, setting or test standard on any of them. Some store pages and the pressure washer manuals call them sound power; everywhere else they go unlabelled.

Fifteen store listings say "Sound Power Level" and seven say "Decibels (dB)" beside a bare number. Manuals that print a figure use either a symbol line, "Sound power level is 96 dB(A).", or a technical data row called "Decibel Rating", and the help center answers "How loud is my...?" with "a decibel rating of" a number.

Sound power is the whole acoustic output of a machine. Sound pressure is the level at one listening spot. A Sun Joe sound power row and another maker's reading at the operator's ear are different things, a split that this explainer on power and pressure walks through.

Only the pressure washer and SBJ702E manuals add the A weighting, so the plain "Sound Power Level" rows form one group here and the dB(A) manual lines another.

Sound power rows on the store

Blowers, chainsaws, a pole saw, a chipper, an ash vacuum, two mowers and a snow blower carry one. The ASHJ201 ash vacuum is the lowest in stock at 92 dB.

Wherever the help center repeats one of these, for the ASHJ201, MJ401E, MJ403E, SWJ803E, SWJ698E, SWJ699E and the "Snow Joe Ultra", it agrees. The SWJ701E, covered below, is the only split. The CJ601E row is new. On October 17, 2026, neither its page nor its manual had a figure; by November 7 the page read "Sound Power Level 108 dB", and the manual still printed none.

How loud are Sun Joe pressure washers?

All the rated ones share a single manual line, "Sound power level is 96 dB(A).", and eight of them are still on the store. Pressure, motor and price leave the figure unchanged, so it cannot separate one washer from another.

The SPX7000-MAX manual is a scanned PDF without a text layer. Viewed as an image, its safety symbol page shows the same LWA 96 dB symbol beside the same sentence.

One older washer did better. "Sound power level is 89 dB(A).", says the SPX3000-MAX manual, 7 dB(A) below the rest, but the store no longer lists that model. Other brands' washers are compared in quiet electric pressure washers.

Several current washers print no figure: the SPX1500-Q, SPX1000, SPX205E-XT, SPX2790-MAX, SPX3000-QW2 and the brushless SPX4800, along with the 20V X20 cordless models.

Chainsaw rows from 85 to 110 dB, all sold out

Every rated handheld saw was sold out. Of the pole saws in stock, the SWJ803E lists 100 dB and the SWJ802E 105 dB.

The 85 dB rows look doubtful.

A 9 amp, 14 inch saw rating 25 dB below a 9 amp, 12 inch one is a gap nobody explains, and the SWJ599E and SWJ699E manuals mention 85 dB only in a warning that "you can be exposed to a noise level of 85 dB (A) or higher", the same warning the 12 and 18 inch saws carry.

The two sources also disagree on the SWJ701E, 107 dB on the store row against 104 dB in the help center. For the SWJ802E, the help center gives 105 dB while the store page has no noise row at all, and the help article for the SWJ800E pole saw has a title and no answer.

Which Sun Joe tools list decibels without saying what kind?

The tillers, the CJ603E chipper, the SDJ616 leaf mulcher and the HJ22HTE hedge trimmer, at 93 to 110 on a plain "Decibels (dB)" row. Whether these are sound power or sound pressure is never stated.

Tillers drawing 6.5, 12 and 13.5 amps all showing 93 reads like one figure copied across the family. The TJ603E and TJ604E were in stock; the 6.5 amp TJ600E was sold out. More tillers appear in quiet tillers.

Chippers sit on three different bases: an unlabelled 94 or 98 for the CJ603E, a 108 dB sound power row for the CJ601E, and a help center "decibel rating" of 113 dB for the sold-out CJ602E. With no shared label, they stay unranked.

Mowers and the one rated snow blower were sold out

The rated mowers list 92 to 96 dB and the one rated snow blower 100 dB, and every one of them was marked sold out on November 7, 2026. No in-stock Sun Joe mower or Snow Joe thrower prints a figure.

The 14 inch MJ401E and 17 inch MJ403E both show "Sound Power Level 92 dB" on the store. The 20 inch MJ408E has no store row, but its manual says "Decibel Ratings 96 dB" and its help center article "Sound power level 96 dB". Reel mowers and 24V cordless mowers carry nothing.

Snow Joe's 18 inch SJ623E lists "Sound Power Level 100 dB", matching the help center's 100 dB for the "Snow Joe Ultra". The wider SJ627E, the 320E and 324E electric shovels and every 24V and 96V cordless thrower print none. For throwers from other brands, see quiet snow blowers.

One figure at a distance, for a generator

Once, and only once, a distance appears: the Power Joe SJG4100LP propane generator, which the help center says "measures at 69db while idle and 72db at Max Load (measured from 23 feet)".

Those are sound pressure readings at about 7 meters, a different quantity from every sound power row above, so they stand alone. The generator was sold out at $899.00, and its manual prints no noise figure. A second help article says the "24V iONMAX Jet Blower runs at about 85-100 decibels". A 15 dB range for a blower with no model number earns a quote and no place in any ranking.

Most of the range has no figure at all

That includes the whole 24V, 48V and 96V iONMAX cordless range and the 20V X20 ECOSHARP tools, from blowers and mowers to snow throwers. Among corded tools, the TJ599E cultivator, the TJ602E and TJ605E tillers, the SWJ800E and SWJ805E pole saws, the SBJ597E blower, the HJ604C hedge trimmer and the AJ-series dethatchers and aerators print none either; their manuals ask for hearing protection but give no rating.

Elsewhere the quiet claims are words. The SWJ802E page promises "a quiet 6.5-amp electric motor", and the SPX4800 page says its brushless induction motor runs quieter than universal motors, with no figure for either. Blower vacuums from other makers are in quiet leaf vacuums.
